This video has strong Project Farm vibes, thank you for the homebrew testing. I had an Anderson window guy come a few weeks ago, told him the CRAP windows that are on my house now are from them and I would never buy one again, now your testing reaffirms my stance.
Interesting and somewhat informative. It would be good to show impacts from something like pebbles or hail at speed. I am not aware of any window problems caused by weight lifting weights in real life, or for that matter 270 lbs hung from a strap off the frame or sash. Fun to watch, none the less.
A friend of mine is on the plus side of 375 pounds, not fat. Was a Football player, now retired. He always buys "The Best" as he can afford too. He was sitting on the window sill of his house that had 1 year old RenewByAndersen windows. The sill cracked and split, cutting his leg a little. Still fighting with them to replace it under warranty as they said it was not designed for that weight. He had sat in the same window many times when it was a wood frame and sill. Same issue with the Andersen slider door frame, split where his boot heel met it.
What i would like and think is way more important is that you show the flashing details on both windows that are included and what each one tells you how to flash. As we all know WATER is the KISS of DEATH of all construction projects.
That is really hard to say. There are over 100 companies that offer black exterior windows. If you're looking for a black window and it must have blinds built in between the glass, that narrows it down quite a bit. If you're looking for a vinyl windows, that narrows it down even more. The only company I'm aware of that makes black windows with blinds between the glass and they are made out of vinyl would be Pella. Otherwise, there are many major brands that make black windows with blinds between the glass but they are going to be windows that are made out of wood.
I have spent 30 years installing windows and I have experience with both of these windows. I’m aware of the manufacturer’s claims regarding strength! But this kind of strength you tested doesn’t really address real world concerns. Once a window is installed, I don’t think these strengths are an advantage.
I have seen first hand Anderson Fibrex window sash break at the lock rail on single hungs from customers apparently slaming them shut. Thats the reason I clicked on this video, I have been leery of pushing sales on Fibrex because I have seen how brittle it can be.
Thank you for may of your informative videos. It is very hard to chose between different windows. I also learnt the pros and cons from your single hung and double hung windows. I think I need not buy all double hung windows except the ones that are high up. The draft in double hung is my concern. Renewal by Andersen gave me their best quote as 31k for 10 3'x5' double hung fibrex windows with inside grids and cedar trim. I think it is very high. Any idea how much should be a reasonable price for 10 windows? Main goal is insulation and no draft.
I'd avoid Renewal. Find a great local company and you'll get a better installation at a better price. I started a website to help people locate a great window company near them. We may have someone in your area. Please visit TheWindowExperts.com
@HoustonWindowExperts Thank you for the quick response. Yes, I already visited your website and submitted a request. I did not see a list of installers in the Portland area on the website. Thank you again.
Been a carpenter for 50years, not a fan of Pella. One thing I always look for decent weather stripping. I want to see at least two layers of weather stripping, preferably three! Triple pane quadruple pane whatever won’t do squat if air leaking around the gasket areas!!! I’ve installed Anderson and I prefer their product.
Awesome job guys. I was not shocked at these tests, fiberglass is definitely stronger than fibers but where fibers really wins is on the paint/durability. Fiberglass windows peel, chip & flake off and Pella claims a warranty will void if you try to repaint them vs fibrex won’t peel, chip or flake and you can paint them if you want.
I sell both myself(well I use sell loosely) I dont like pella, they pay a lot for a name to be honest, in my opinion, and in NY their service is not good.. But I will most certainly be selling even less of the 100 series now.. I will stick with the Marvin Essential, which is a similar makeup of the Impervia, but in my opinion much better quality aesthetically. Can you do a comparison on the Impervia and Essential if you have not as of yet? Appreciate your videos!!
VS implies a victor. A battle. You basically did a commercial to sell windows. They’re both awesome! You should buy them both! What did we learn? You’re a salesman.
Also can you do a direct comparison on Anderson's best and Pellas best thermo producing windows double and triple pane vs the European windows like Schuco, Neuffer, Zola, Alupro,, Loewen, Unilux, Schuco, Yawal, Sierra Pacific windows etc. This type of information is what consumers and contractors need. Also lay out price comparisons. This is the one area in my search for building our two new custom homes that i can't find reliable/unbiased information.
You would have to compare Pella with plastic wrap and duct tape. The plastic and tape would win. And last longer. Pella makes terrible windows...CHeck out older reviews, the only positive ones are those that have just been installed, and people like they are clean.
UL UNDERWRITING LABS DO these very test and other test for fire and safty And its in a controlled environment with machines that will take accurate measurements then find the stress points and limits of a product in all aspects, what im seeing of these nother product has any closed cell or lightweight spray foam in them A closed cell foam would make the unit more ridged and more energy efficient But neither company takes advantage of this. All you get is an air gap. Hell for 40k bucks for 11 windows youd think it was built better then a new Ford pickup truck but they are not. Thd Ford truck has a closed cell foam in all body structure supports. You can make thin products if somthing else is filling the void. As much as I hate wood rot, woods still a better option.
Appreciate your videos, have learned more from you than just about any other on RUclips and wish I lived closer to Houston. But how does this testing help someone make a decision between fiberglass and Fibrex? A typical 30x54 window sees a 300 pound total load when wind speed is about 120mph, and it's distributed over the whole window area not concentrated as in this test. So the actual deflection each of these materials' frames will see under normal or even elevated circumstances (say, 60 mph wind) is going to be negligible. Or, close enough to one another that I'm probably not making a buying decision based on this kind of strength performance. The impact test is more relatable and interesting, but drop an iron weight on a high-end aluminum-clad frame and I bet that doesn't work out very well, either. Andersen makes A-series fiberglass as well. What might be more interesting is how fiberglass compares to Fibrex in terms of temperature expansion/comtraction, long-term durability in its assembly, color stability over time, etc. All that said, I realize much of what you set out to do here was to verify Pella's strength claims. Thanks.
I was surprised at Renewal By Andersen Limited Warranty only covers installation for 2-years and does not cover "performance of the low-maintenance exterior glass coating on products with HighPerformance Low-E4® glass"
You perform a great service. I live in the Las Vegas, NV area. In the summer we are very hot (107+) and very dry (2%). But we can get below 32 in the winter. My house has 1999 contractor vinyl windows and they have held up pretty good. But it is time to replace them. Vinyl is what most replacement window companies in the area offer. The Anderson guys say vinyl is not good (yet their product is 60% vinyl). But Anderson is about ~2x the price of high grade vinyl and the warranties are about the same. I want to also consider Pella fiberglass and vinyl. Can you offer any advice for a very hot and very dry climate? Thanks.
I also live in Vegas, and my house was built in 1988 with custom aluminum windows that have failed which is to be expected after so long. I got a few quotes 73k for Marvin fiberglass, 53k for Milgard vinyl, and ultimately 40k for Pella Impervia fiberglass, I'll probably be going with the Pella. Note: my windows are black
Thanks for doing this video guys, this helped me make my decision. I recently had an Andersen Rep at my house and after the quote I recieved, I felt the price was quite outrageous actually. I was going to consider them for a different product I know wouldn't have been as expensive, but now I wouldn't recommend them for a Barbie Dream House!
Anderson Works with you ! Pella Pay when job is complete ! A single hung window$1,100.00 installed ? And Winters are brutal ! Might as well leave the window open !
I'm more curious how well or how they resist transferring heat and cold. Also how well the windows insulate. It's unlikely that they will be hit by a weight.
The reason the temperature was rising so fast is because these materials are good insulators. The heat cannot make its way into the part very well so the surface warmed up fast.
Jeff, Great video and actually the idea behind your "tests" isn't really that far off from some of the actual testing that windows and/or window glass might be subjected to before consumers ever see it.
Ceteris paribus (all things equal) in terms of window size, similar glass package, same installation team, installed at the same house, etc. - are they priced equally? Or does one come with a price premium? Premium percentage?
Thank you for watching. The Pella Impervia should cost about 30% more than the Andersen Fibrex. However, in the wrong hands, Fibrex would be pitched at double the price of the Impervia.
@@HoustonWindowExperts Thanks Jeff for the prompt reply. Would I be correct in assuming if I wanted to remain within the Andersen family of windows I would need to move to the A-Series to get similar performance to the Impervia? If so, are the A-Series and Impervia by Pella on par in terms of pricing? Thanks in advance!
Not necessarily. Andersen does not have any windows that are true fiberglass. If you wanted to compare the Pella impervia to anything else, it would be the Milgard fiberglass windows or the Marvin fiberglass.
@@HoustonWindowExperts I'm deciding between these 2 windows and Its so hard to choose whether it's worth spending that extra 30% for the Impervia. That is a significant difference but it is a better window. What to do???
This came up with perfect timing. I’m remodeling a 61 year old house and started researching windows yesterday. I’ve literally been making a spreadsheet to decide between Andersen or Pella. Thank you!
Would you still be able to offer my friend that spreadsheet? She is replacing windows in her forever home for her and her 21-year-old disabled son in MI. I am researching this very topic on her behalf.
@@louisbrien7509 Sadly I have already deleted the spreadsheet. I was really just doing a pro VS con for each. I ultimately went with the Pella windows. Best recommendation is to have their sales team come out and show you the actual windows or go to a showroom. Also... just a heads up... Lead times are about 5 months on order to install date.
@@jasonreaves4789 Julie has signed with Anderson after negotiating a price break to bring their product closer to the price of Pella's, they are scheduled for installation in June/July, she is very glad they have their own financing too. Not cheap by any means.
Who did you end up going for. Renewal quoted me $27k for 6 windows and one patio door. Two windows being doubles. I was in shock. The starting price was $39k…
I live in Michigan and can tell you our windows have never been subjected to 50 or 100 lbs of weight, so while these tests were fun to watch, they don’t really matter to me. The real test is how the joints separate when the windows are fiberglass - the joints are connected with metal fasteners and when it’s cold those separate and result in drafts. Fibrex windows are fused together with high heat and pressure, just as you pointed out. They don’t separate at any cold temperature that we’ve experienced. I’ve had both types of windows. Fibrex is by far superior and more energy efficient. Additionally, fiberglass requires regular maintenance in the form of gel coating every year. Renewal by Andersen’s Fibrex windows are completely maintenance free. Bottom line is that Fibrex is the better product when you test it for what really matters to us. As I’ve said I’ve had had both in my house when It was 20 degrees below zero for several days.Now that’s a real test! Sorry Houston.
Thank you for watching and for your comment. It's a common sales pitch for fibrex salesmen to tell you that fiberglass needs a new gel coat every year. They must be thinking about fiberglass that's used for boats. This is nothing like that at all. As long as you are enjoying your windows, that's great!
Marta, it sounds like you work for the Renewal folks. The gel coat story is completely inaccurate but a rehearsed phrase by RBA reps. Infinity windows use an Acrylic finish and Pella uses a wet paint finish. Neither one will ever require gel coat applications. (they're not boats). The corner keys are a high density plastic that conducts virtually nothing. (and does not expand and open gaps). By the way, I am from Grand Rapids!
Thanks for watching and for your question. If you look through my videos you will see that I have specific videos on each of those products and outline their benefits and their drawbacks. That might be helpful for you to watch.
@@HoustonWindowExperts my mistake. What I meant was different materials they both have meaning wood fibers and pvc verses the Total fiberglass in Pella. Doesn’t Andersen now make an all fiberglass sash?
I just bought Anderson windows what is the best model they produce? I'm paying 27000.00 dollars for 5 windows and 1 patio door. Thanks for your input 👍
@@HoustonWindowExperts “that is expensive” is an ignorant quick reply without knowing anything about the window types or sizes , etc.. including a patio door!
I'm am currently in the process of becoming an employee of Pella. Would you able to discuss the pros and cons you have faced to ensure I make the right career choice? Please PM me
@@HoustonWindowExperts Indeed! A window question for you... Have you heard of United Windows and Doors on out NJ? They are sold in Lowes and after comparing the "vinyl feel" of their 7400 replacement window compared to Pella 250 and even 450 and Anderson 100, the United felt less vinyl hollow to me and had good corner welds. I did look at the companies you represent and they were all Western or Southern based companies which makes sense for you so I suspect you may not have come across United unless they are in Lowes across the country. Another reason I like United is the factory is a 1 hr drive from me.
What is this test proving in the real world installed up right in a lumber frame. Unless someone is throwing boulders at your window frames what's the point ?
UV testing is done by exposing the vinyl to accelerated exposure. (usually is a lab). The main ingredient you would use in your vinyl batter to have a higher resistance to UV would be titanium dioxide. I would look for a vinyl product that brags about how much titanium dioxide they use. That usually gives you an indication as to how well it will resist exposure.
I wish I had access to some European windows. I think that would be an awesome comparison. If you, or someone reading this comment, has access to some of European Windows, please reach out to me.
Kolbe Forgent is in a separate category. It's a polymer and fiberglass hybrid. I haven't personally had any experience with it but I do like the fact that it can have a wood interior option. I think the frames are a little too bulky for smaller windows because of how much glass space will be lost. By the way, we may know some great window companies in your area. Check out JeffsList.com
@@HoustonWindowExperts Thanks for the reply. We are leaning towards the Kolbe Forgent because they have large impact rated sliders and the wood interior is very appealing. Haven't found any other brands with this combo.
@@HoustonWindowExperts Yes I did notice that the impact rating drastically reduced the available options for large sliders (i.e. Pella Impervia does not offer impact rated sliders). Is there a reason you do not carry Kolbe products? What is your overall impression of them? Also, thanks for the link to your website. I will check it out.
Most manufacturers do not want to have too many dealers in town with their products. It's about protecting their territory. There was a dealer in our area that already sells this product and so we do not want to add that to our list because we would not sell enough of it to be well-informed.
From a strength perspective yeah the impervia looks good but I am really disapointed in how easy the finish chipped off the impervia. IM about to order impervia for a new build and that is one thing the marvin guys said was the impervia is just powder coated vs acrylic. It shows here. I would like too know what the marvin would do. I wasnt going with marving because I prefer the more modern interior look on the inside. The marvin essentials wont mull a transom too the top of a triple casement we have. And the elevate is wood interior, I just dont like the look. The other thing im not super excited about on the impervia is the exterior corners stick out like a sore thumb, you can see the light colored fiber fibergless
@@HoustonWindowExperts I really wish those windows looked like impervia from the interior. They look more like plastic. Really stinks because the finish seems better for sure form an exterior perspective. And the marvin modern is double the price.
I live in Michigan and can tell you from first-hand experience that the Fibrex product by Renewal by Andersen is far superior in terms of energy efficient. They cut my energy bills by 25%. Now, if you plan to drop 100 lb weights on your windows, I can see why you may want to go with Pella. (Joking, of course)
Lol... I'm glad to hear that. Any energy efficient window is expected to give you at least a 30% reduction in energy cost. I'm glad you're happy! Thank you for watching and your comment.
When I see the title, I just cringe. I was a builder in Indiana for 30 years. The cost of either of these manufacturers has a past that is riddled with destruction both to homes and the financial cost left to the consumer. Now I see these products with insane prices and I just look to history. The mess they left their customers in is horrific. I understand this is a new product... that is still no excuse for the mess they left to homeowners.
I would take a high quality vinyl over the Fibrex product. It's too brittle, in my experience. If the budget allows, the Impervia would be better to have than Fibrex or a lesser quality Vinyl.
@@HoustonWindowExpertsWhy is being too brittle a bad thing? The Renewal reps are trying to sell me that vinyl is too flimsy and becomes warped over time, whereas the Fibrex stays the same shape 20 years later. They didn’t use the world brittle, LOL, but I interpreted Fibrex’s rigidity (my word choice) as a good thing - though I would have used the words “firm” or “solid” because brittle implies it will break…is that what you mean? The Fibrex breaks? Thanks! Still trying to decide…
The fiberglass products I'm aware of use corner keys and screws that are also sealed with a butyl product. I'm unaware of any glued fiberglass windows.
Wouldn’t you want a little bit of flexibility bend wise in a window - as long as it could flex back? I don’t necessarily understand why being stronger against torsional stresses would be better for a window in a static wall, except for minor weather related swelling, which I would think then flexibility would be better so that seals don’t break and pop necessarily?
This is comparing Apples and Oranges. Yes Fiberglass is always going to be stronger than Composite Material. Fiberglass is also always going to be more expensive than Composite. I appreciate the comparison. But it should be a comparison to upsell Fiberglass vs Composite, Not Pella Vs Anderson.
Paul, thank you for your comment. I did this comparison because both companies compare these two materials in the home and claim to be better than each other. In my market, the Andersen brand actually sells for more than the Pella brand. Having this information is helpful to a homeowner who may be confused about the claims being made by both brands.
With all due respect, Paul. Fiberglass is a brand name and it is a composite. Fibrex is a brand name and is also a composite. This is actually an apples to apples test. Also, carbon fiber is a composite and is almost always stronger and priced higher than fiberglass products. Great video guys! Thanks.
This test proves nothing and when are you going to have 300 lbs on a small piece of your window? Or have weights dropped on it? Andersen’s glass pack which is 80% of the window roughly. Is way better pella doesn’t guarantee the argon gas the minute it’s manufactured. Look in the warranty.
@@Grande79 same glass, not same warranty. Pella offers no warranty after manufacture date, Andersen offers full replacement for 20 years. I am currently looking at both and still struggling, price is similar for both windows on my final quote for me because I have alot of arches and those are pricy with fiberglass. Hard to justify spending $60k on new windows but I definitely won't do straight vinyl in hot Texas heat.
While a warranty is important, it should not be the first concern when buying a window. In fact, the better the window, the less you need a warranty. But to answer your question, the best I've heard of is from Simonton windows. They offer a lifetime warranty that is transferable twice. Not like you should care after the first warranty anyway.
Look into improveit windows. Their warranty is crazy good. I'm actually considering having their windows put in my house. I'm learning about how to choose the right one. The one thing that I learned is their window is kinda chunky.
The best way to know who makes their window is to ask for the NFRC number. Go to the NFRC website and enter that number. That will tell you WHO is actually making the window. You can then go shop for that same window and buy it for 39-40% less.
Gotta take reeeeaaaally good care of the fiberglass to keep it lookin nice since paint doesn’t bind well without the coating…. May be strong but definitely not maintenance free that’s for sure
I agree, you have to take care of any window you purchase. I do like that this is a powder coat finish and it's much better for adhesion than a painted product would be.
I’ve had no problems with my new home built in 07. I have all fiberglass entry doors which were primed and painted. I haven’t touched them since new in 07. I hate steel as it dents and rusts and wood is beautiful but worrisome with weather.

What brand is best to order windows in BLACK? Preferably with built in blinds.
That is really hard to say. There are over 100 companies that offer black exterior windows. If you're looking for a black window and it must have blinds built in between the glass, that narrows it down quite a bit. If you're looking for a vinyl windows, that narrows it down even more.

I recently had an Andersen Rep at my house and after the quote I recieved, I felt the price was quite outrageous actually. I was going to consider them for a different product I know wouldn't have been as expensive, but now I wouldn't recommend them for a Barbie Dream House!
Lol... Love it!!
Anderson Works with you ! Pella Pay when job is complete ! A single hung window$1,100.00 installed ? And Winters are brutal ! Might as well leave the window open !
Anderson, $2200+ per window. And all will finance!
Wow, that was great Jeff. Pella! I'm think of purchasing the 250 series. I'm doing my homework now. Thanks again.
Thanks for watching
I'm more curious how well or how they resist transferring heat and cold. Also how well the windows insulate. It's unlikely that they will be hit by a weight.
The Impervia performs better in heat and cold transfer.
I live in the Tampa Florida area, do you have companies in this area I can contact for home windows?
Yes, please check out JeffsList.com
The reason the temperature was rising so fast is because these materials are good insulators. The heat cannot make its way into the part very well so the surface warmed up fast.
Thank you for your comment.
Jeff,
Great video and actually the idea behind your "tests" isn't really that far off from some of the actual testing that windows and/or window glass might be subjected to before consumers ever see it.
That's good to know. Thank you for watching
Not bad but you did turn the fibrex around 2x giving it an unfair advantage and it still failed! lol
Agreed
I'm in the market for new windows and I found your unscientific test very informative hot cold and bend thank you so much
Thanks for watching
Ceteris paribus (all things equal) in terms of window size, similar glass package, same installation team, installed at the same house, etc. - are they priced equally? Or does one come with a price premium? Premium percentage?
Thank you for watching. The Pella Impervia should cost about 30% more than the Andersen Fibrex. However, in the wrong hands, Fibrex would be pitched at double the price of the Impervia.
@@HoustonWindowExperts Thanks Jeff for the prompt reply. Would I be correct in assuming if I wanted to remain within the Andersen family of windows I would need to move to the A-Series to get similar performance to the Impervia? If so, are the A-Series and Impervia by Pella on par in terms of pricing? Thanks in advance!
Not necessarily. Andersen does not have any windows that are true fiberglass. If you wanted to compare the Pella impervia to anything else, it would be the Milgard fiberglass windows or the Marvin fiberglass.
@@HoustonWindowExperts I'm deciding between these 2 windows and Its so hard to choose whether it's worth spending that extra 30% for the Impervia. That is a significant difference but it is a better window. What to do???
@@jasn010impervia much cheap than Anderson fibrex😊
This came up with perfect timing. I’m remodeling a 61 year old house and started researching windows yesterday. I’ve literally been making a spreadsheet to decide between Andersen or Pella. Thank you!
Great! Thank you for watching!
Would you still be able to offer my friend that spreadsheet? She is replacing windows in her forever home for her and her 21-year-old disabled son in MI. I am researching this very topic on her behalf.
@@louisbrien7509 Sadly I have already deleted the spreadsheet. I was really just doing a pro VS con for each. I ultimately went with the Pella windows. Best recommendation is to have their sales team come out and show you the actual windows or go to a showroom. Also... just a heads up... Lead times are about 5 months on order to install date.
@@jasonreaves4789 Julie has signed with Anderson after negotiating a price break to bring their product closer to the price of Pella's, they are scheduled for installation in June/July, she is very glad they have their own financing too. Not cheap by any means.
Who did you end up going for. Renewal quoted me $27k for 6 windows and one patio door. Two windows being doubles. I was in shock. The starting price was $39k…
Do a strength test to the corner joints.
Good idea for the next one.
I live in Michigan and can tell you our windows have never been subjected to 50 or 100 lbs of weight, so while these tests were fun to watch, they don’t really matter to me. The real test is how the joints separate when the windows are fiberglass - the joints are connected with metal fasteners and when it’s cold those separate and result in drafts. Fibrex windows are fused together with high heat and pressure, just as you pointed out. They don’t separate at any cold temperature that we’ve experienced. I’ve had both types of windows. Fibrex is by far superior and more energy efficient. Additionally, fiberglass requires regular maintenance in the form of gel coating every year. Renewal by Andersen’s Fibrex windows are completely maintenance free. Bottom line is that Fibrex is the better product when you test it for what really matters to us. As I’ve said I’ve had had both in my house when It was 20 degrees below zero for several days.Now that’s a real test! Sorry Houston.
Thank you for watching and for your comment. It's a common sales pitch for fibrex salesmen to tell you that fiberglass needs a new gel coat every year. They must be thinking about fiberglass that's used for boats. This is nothing like that at all.
As long as you are enjoying your windows, that's great!
Love it!! Great points!!! And totally agree!!
Thanks for watching
Insulation and weathering resistance are the most common concerns in cold zones; I prefer Andersen.
Marta, it sounds like you work for the Renewal folks. The gel coat story is completely inaccurate but a rehearsed phrase by RBA reps. Infinity windows use an Acrylic finish and Pella uses a wet paint finish. Neither one will ever require gel coat applications. (they're not boats).
The corner keys are a high density plastic that conducts virtually nothing. (and does not expand and open gaps).
By the way, I am from Grand Rapids!
Nice videos, thank you. I don’t see an email address. I hope you can refer someone in the Clearwater Florida area.
Please check out JeffsList.com
Gooooooooooooo Pella, thank you, That is such a great product.
Thanks!
what about the comparation between thermal break aluminium window and PVC windows? what is your idea ? which one you will advice ?😀
Thanks for watching and for your question. If you look through my videos you will see that I have specific videos on each of those products and outline their benefits and their drawbacks. That might be helpful for you to watch.
This is good but the glass type means a lot. Who makes the glass? And I believe Fibrex costs less than Pella so not sure this is a fair test.
The glass is exactly the same in both units. They are made by Cardinal Glass.
@@HoustonWindowExperts my mistake. What I meant was different materials they both have meaning wood fibers and pvc verses the Total fiberglass in Pella. Doesn’t Andersen now make an all fiberglass sash?
Andersen does not have a fiberglass product. It's Fibrex.
I just bought Anderson windows what is the best model they produce? I'm paying 27000.00 dollars for 5 windows and 1 patio door. Thanks for your input 👍
That is expensive! I hope it's great!
@@HoustonWindowExperts “that is expensive” is an ignorant quick reply without knowing anything about the window types or sizes , etc.. including a patio door!
What would you have said?
Been waiting for this video , just started working as a Retail Sales Consultant for Pella 1 month ago, love your videos!
Thank you for watching!
I'm am currently in the process of becoming an employee of Pella. Would you able to discuss the pros and cons you have faced to ensure I make the right career choice? Please PM me
I’m putting black Impervia in my entire house. Looks good.
Congratulations!
The drop test should include one at the highest on a fresh spot. Hitting the same spot incurs cumulative damage which would really never happen.
oops commented too soon I see the fresh drop was done.
Thank you for your comment.
Gotcha
@@HoustonWindowExperts Indeed! A window question for you... Have you heard of United Windows and Doors on out NJ? They are sold in Lowes and after comparing the "vinyl feel" of their 7400 replacement window compared to Pella 250 and even 450 and Anderson 100, the United felt less vinyl hollow to me and had good corner welds. I did look at the companies you represent and they were all Western or Southern based companies which makes sense for you so I suspect you may not have come across United unless they are in Lowes across the country. Another reason I like United is the factory is a 1 hr drive from me.
Great video thks!!
Glad you liked it!
Thank you. Interesting. Though in my experience, hard hail tends to come when the weather is warmer.
Thanks for watching and your comment.
What is this test proving in the real world installed up right in a lumber frame. Unless someone is throwing boulders at your window frames what's the point ?
I'm confused on if this is the fully fibrex window material or an anderson 100/400 which just has the fibrex coating on the exterior?
This is fully Fibrex.
Wow I'm literally looking at a circular add for Fibrex vs. Vinyl. LOL.
Thank you for watching!
So informative thank you!! Subscribed!
Thanks for watching and thanks for the sub!
What are the price difference is? For all we know, pella is four times the price
Depends on what part of the country you live in, and who your dealer is. In most cases, the Pella product is going to be about 10% more expensive.
@@HoustonWindowExperts nice, not as much as I thought it would be! Thank you
On the Dock without Steel Toes! OSHA not Approved 😂😂
Brittleness is worse the colder it gets. Deflection should be worse the warmer it gets.
Agreed
Can you please review Albert Genau as well? I couldn't see anywhere in US. But when i visited Spain it was very common
Hi, do you have access to one so I can review it?
@@HoustonWindowExperts no I don't maybe you can reach out to the company
I love watching your videos' they teach me quite a lot about the different product lines. Thank you Jeff😆
Thanks for watching
How do you test the UV resistance? Which material is best UV resistance?
UV testing is done by exposing the vinyl to accelerated exposure. (usually is a lab). The main ingredient you would use in your vinyl batter to have a higher resistance to UV would be titanium dioxide. I would look for a vinyl product that brags about how much titanium dioxide they use. That usually gives you an indication as to how well it will resist exposure.
What's your opinion on the performax54? Sold by improveit
See my other reply to your question.
Just signed up. Looking for windows in San Antonio for a new build.

How does Milgard fiberglass compare to these two?
I prefer Milgard and Pella over the Andersen Fibrex.
Next Windows I Buy Won’t be Pella ! Single Hung window $1,100.00 each ! And still feel cold air in the winter !
Yikes.
agree that Pella is stronger and less deflection. Andersen has more deflection and distortion
Richard
Thank you for your comment.
How would weights be dropped with the glass in it
Please elaborate?
Pella vs Marvin. I have both installed
Great!
What do you think of the Alside 80 series?
Sorry but I don't know much about it.
With a strait face Anderson just gave me a quote of $3k per window
That's cheaper than what I normally hear.
Y don't you show & talk about impack windows
Thank you for watching. We don't sell them so I don't have any to demo.
Thanks for the video. Itd be great to see something on European windows.
I wish I had access to some European windows. I think that would be an awesome comparison. If you, or someone reading this comment, has access to some of European Windows, please reach out to me.
@@HoustonWindowExperts Klar and Eurowindows, both in Norwalk, Ct. and Rhea, Darien, Ct. , all manufactured in Poland.
Oknoplast.
How would either of these compare to the Kolbe Forgent windows? Do you have any experience with Kolbe products?
Kolbe Forgent is in a separate category. It's a polymer and fiberglass hybrid. I haven't personally had any experience with it but I do like the fact that it can have a wood interior option.
I think the frames are a little too bulky for smaller windows because of how much glass space will be lost.
By the way, we may know some great window companies in your area. Check out JeffsList.com
@@HoustonWindowExperts Thanks for the reply. We are leaning towards the Kolbe Forgent because they have large impact rated sliders and the wood interior is very appealing. Haven't found any other brands with this combo.
If you need impact rated windows, that does narrow down your field quite a bit. Good luck.
@@HoustonWindowExperts Yes I did notice that the impact rating drastically reduced the available options for large sliders (i.e. Pella Impervia does not offer impact rated sliders).
Is there a reason you do not carry Kolbe products? What is your overall impression of them? Also, thanks for the link to your website. I will check it out.
Most manufacturers do not want to have too many dealers in town with their products. It's about protecting their territory. There was a dealer in our area that already sells this product and so we do not want to add that to our list because we would not sell enough of it to be well-informed.
Dude cloning is illegal
LOL
Awesome video as always , you should test Elevate windows with that test
Great suggestion!
From a strength perspective yeah the impervia looks good but I am really disapointed in how easy the finish chipped off the impervia. IM about to order impervia for a new build and that is one thing the marvin guys said was the impervia is just powder coated vs acrylic. It shows here. I would like too know what the marvin would do. I wasnt going with marving because I prefer the more modern interior look on the inside. The marvin essentials wont mull a transom too the top of a triple casement we have. And the elevate is wood interior, I just dont like the look. The other thing im not super excited about on the impervia is the exterior corners stick out like a sore thumb, you can see the light colored fiber fibergless
The Marvin Ultrex is far better than Pella Impervia. The finish is so awesome!
@@HoustonWindowExperts Are you referring too the essentials line?
Yes, or the Infinity product.
@@HoustonWindowExperts I really wish those windows looked like impervia from the interior. They look more like plastic. Really stinks because the finish seems better for sure form an exterior perspective. And the marvin modern is double the price.
That was a good test. I live in New England and we have both hot and extreme cold. Paella has my interest.
Thank you for watching.
I also like paella, that is, seafood rice 😁😉
I live in Michigan and can tell you from first-hand experience that the Fibrex product by Renewal by Andersen is far superior in terms of energy efficient. They cut my energy bills by 25%. Now, if you plan to drop 100 lb weights on your windows, I can see why you may want to go with Pella. (Joking, of course)
Lol... I'm glad to hear that. Any energy efficient window is expected to give you at least a 30% reduction in energy cost. I'm glad you're happy! Thank you for watching and your comment.
When I see the title, I just cringe. I was a builder in Indiana for 30 years. The cost of either of these manufacturers has a past that is riddled with destruction both to homes and the financial cost left to the consumer. Now I see these products with insane prices and I just look to history. The mess they left their customers in is horrific. I understand this is a new product... that is still no excuse for the mess they left to homeowners.
Thanks for watching and your comment.
Great video. I reside in Philly area. Can you provide a Philly window replacement expert please?
Ruth, you can email us at the office info@houstonwindowexperts.com and someone can see if we have a referral in your area.
I will never use fibrex windows again. Frames and sash bow over time, especially the darker colors. Some wont even open and close , just 5 years old
Excellent Video!
Thank you very much!
Either one of these are better than any vinyl window, correct?
I would take a high quality vinyl over the Fibrex product. It's too brittle, in my experience. If the budget allows, the Impervia would be better to have than Fibrex or a lesser quality Vinyl.
@@HoustonWindowExpertsWhy is being too brittle a bad thing? The Renewal reps are trying to sell me that vinyl is too flimsy and becomes warped over time, whereas the Fibrex stays the same shape 20 years later. They didn’t use the world brittle, LOL, but I interpreted Fibrex’s rigidity (my word choice) as a good thing - though I would have used the words “firm” or “solid” because brittle implies it will break…is that what you mean? The Fibrex breaks? Thanks! Still trying to decide…
I liked the clear framed glasses better. The dark ones make it seam like you're hiding behind them.
Thanks for the feedback.
As a production manager for an Austin-Area window install company... I don't think I'd recommend Andersen again.
WOW the Anderson Window got destroyed......
Thank you for watching.
Pella impervia has serious frost issue.
I think it's hard to find any window that does not have Frost issues in a really cold climate. Are you up north?
But when making the frame of the window fiberglass has to be glued. Your opinion on glued or mortise and tenon joint?
The fiberglass products I'm aware of use corner keys and screws that are also sealed with a butyl product. I'm unaware of any glued fiberglass windows.
Wouldn’t you want a little bit of flexibility bend wise in a window - as long as it could flex back? I don’t necessarily understand why being stronger against torsional stresses would be better for a window in a static wall, except for minor weather related swelling, which I would think then flexibility would be better so that seals don’t break and pop necessarily?
Glass is rigid. If the frame flexes too much you end up with seal failures.
@@HoustonWindowExperts ok got it - that does make sense.
This is comparing Apples and Oranges. Yes Fiberglass is always going to be stronger than Composite Material. Fiberglass is also always going to be more expensive than Composite. I appreciate the comparison. But it should be a comparison to upsell Fiberglass vs Composite, Not Pella Vs Anderson.
Paul, thank you for your comment. I did this comparison because both companies compare these two materials in the home and claim to be better than each other. In my market, the Andersen brand actually sells for more than the Pella brand. Having this information is helpful to a homeowner who may be confused about the claims being made by both brands.
With all due respect, Paul.
Fiberglass is a brand name and it is a composite.
Fibrex is a brand name and is also a composite.
This is actually an apples to apples test.
Also, carbon fiber is a composite and is almost always stronger and priced higher than fiberglass products.
Great video guys! Thanks.
Thank you for watching.
@@Craizg35 which brands use carbon fibers?
I don't know if any company that makes carbon fiber windows.
Wrong kind of testing… put fiberglas in direct sunlight without doing a coating to protect from UV damage every few months and see what happens 😂
I've done that. I installed thousands of fiberglass windows for over a dozen years in the Houston weather and have had zero issues.
Dang it I just ordered Andersen 100 windows
Its okay, the Andersen 100 is 30% cheaper than Pella Impervia. That is significantly less.
This test proves nothing and when are you going to have 300 lbs on a small piece of your window? Or have weights dropped on it? Andersen’s glass pack which is 80% of the window roughly. Is way better pella doesn’t guarantee the argon gas the minute it’s manufactured. Look in the warranty.
Thank you for your opinion.
@@Grande79 same glass, not same warranty. Pella offers no warranty after manufacture date, Andersen offers full replacement for 20 years. I am currently looking at both and still struggling, price is similar for both windows on my final quote for me because I have alot of arches and those are pricy with fiberglass. Hard to justify spending $60k on new windows but I definitely won't do straight vinyl in hot Texas heat.
Agreed
Imprervia frames a little stronger but Andersen has a much better glass package and efficiency
You can get comparable glass packages from either manufacturer and they both use Cardinal glass.
Jeff, what manufacturer offers the longest or best warranties? Thanks
While a warranty is important, it should not be the first concern when buying a window. In fact, the better the window, the less you need a warranty. But to answer your question, the best I've heard of is from Simonton windows. They offer a lifetime warranty that is transferable twice. Not like you should care after the first warranty anyway.
Look into improveit windows. Their warranty is crazy good. I'm actually considering having their windows put in my house. I'm learning about how to choose the right one. The one thing that I learned is their window is kinda chunky.
The best way to know who makes their window is to ask for the NFRC number. Go to the NFRC website and enter that number. That will tell you WHO is actually making the window. You can then go shop for that same window and buy it for 39-40% less.
Gotta take reeeeaaaally good care of the fiberglass to keep it lookin nice since paint doesn’t bind well without the coating…. May be strong but definitely not maintenance free that’s for sure
I agree, you have to take care of any window you purchase. I do like that this is a powder coat finish and it's much better for adhesion than a painted product would be.
I've found it to be extra delicate in transportation and install
But I haven't worked with fibrex
I’ve had no problems with my new home built in 07. I have all fiberglass entry doors which were primed and painted. I haven’t touched them since new in 07. I hate steel as it dents and rusts and wood is beautiful but worrisome with weather.
Good point.
