After quite a few years of designing SIPS and visiting a plant, I am a fan too!
Love my home made air to air heat exchanger .
What a brilliant concept.

Useful information, thanks for posting
Great overview! Thank you!
Good Morning BorntoRunBarefoot! I've never seen SIPs in anything different than 4 feet widths, but the lengths do vary. 8 feet is the shortest, and I've worked with panels that are 16 feet long. I've heard of panels as long as 24 feet. Are you planning to build with SIPs? After living in a structure built with them, I really like them.
Drop by my website stevemaxwell.ca for a visit sometime. You'll find lots of stuff there, including tool giveaways, articles and the chance to ask me questions.
Bye for now and thanks for watching!

I've got a problem with the price being 5% higher than stick built homes when you know damn good and well that thosr sections being built cost less than a stick built section and the fact that your cutting down on material and man hours worked then why is it 5% higher your saving a shit load at the normal rate of a stick built so why 5% more and how I know is that I've been in business my entire adult life and no company takes on a new design in building if it doesn't mean cheaper for them because it doesn't matter if the amount that it's better is 100 times the previous if it doesn't save them money and is going to cost them 5% more they will not do it unless it's mandated by law and then they'll try to get around it all I can see is this way saves money on 2x4 and 2x7 and truses less wood in a building and foam is cheaper than wood or you'd be building that section out of small truse like beams inside it for support
There used to be a company here in northern West Virginia called panelcraft. They would make any size you want up to 42 feet long. You could put up four walls with just 4 panels. They sold the business and I can't find them anywhere like that. They actually cost a lot less than traditional building. Seems like it caught on and it is a lot more expensive now
@@who-manwho4182 SIP panels cost more to make, not less, than stick frame. A stick frame can be put up by 2 guys and hand tools. Quality is down to subjective onsite skills. SIP panels involves a factory, CNC machinery, Certification & testing (no grandfather rights here...), and regulatory compliance. It's not even an 'apples vs apples' comparison you're making, it's a 'fruit vs veg' comparison..... And if the only thing that matters to you is price, then you're missing a whole other bunch of points...........
Here in Ireland, we can make panels up to 12m long x 3m wide. Most roof panels we make are up to 5m long x 2.38m wide. For walls our most common panel sizes are in the region of 4m - 6m long x 3m high. All are craned in: too heavy for manual handling.
This video is really fabulous. And the way of demonstrating the SIPs uses and installation is excellent. Thanks for sharing it.
Awesome informative video 👍👍🌹🌺 excellent
Hi Steve,
Can SIP's be used for those wanting to build a Passive home? You mentioned saving around 1/2 on energy bills but I was sure I have read Passive homes save even more.
Finally for a tiny house on a trailer build,I think the only SIP choice would need to be the thinnest ones.That is because of the narrow width of the build.If using the 4 1/2 width,what is the R value there?
Thanks so much,Tim.
Hi Steve,
I have done field cutting in the past when the homeowner can't decide where to put a window until the walls are up and they are standing inside the structure. Sips are great for that especially when the window or door opening is under 4'.
I am in SW Minnesota and the manufacture I use pre-cuts all my panels for me. It's fantastic. I am at the point now where sip structures is all I do. (Not sure how to send pictures)
I am surprised there are no manufacturers by you who would do cutting. Where are you located? My supplier has shipped to New Zealand, Japan, etc....
Take care!
very nice Thank You Steve!
Well,I had started building a Small house for me and my wife in 2003,I paid a guy to frame it and get in the dry,and same sad story He run off with the Money!We had just got through losing everything we had in a flood in 2002.I live in Texas Hill Country about 40miles north of San Antonio.Anyway,I had a 5th wheel we pulled up here on the property and have been living in it.I'm Disable from a construction accident but can still do some work.I've been trying to figger out how to get a home built on not much money!ha,ha.Like your Product!Thank You for the Reply Steve!!
How long do SIP houses maintain structural stability when they are fully involved by fire? Running electrical lines in continuous void spaces around flammable foam seems like a hazardous application. What is SIP's resistance to electrical arcing compared to fiberglass insulation?
Electrical lines are not meant to be bare and cannot spark in wall cavities if installed correctly. If rodents are a concern for chewing wires, there is less likelihood for rodents to burrow into the dense hard foam than in fiberglass. Also, many newer foams are treated with a boron solution during manufacturing for fire resistance. Paper faced fiberglass is going to spread fire much faster than a newer SIPs panel.
Great vid, very informative. I read in comments what you said regarding ants. Yikes! I live in the southeastern USA. What would you do to prevent ant nesting?????
You said all SIPS are OSB/foam core but what i about aluminum or steel skins? I know they exist. Do you have any info in that regards?
Thanks for a great video. Is there a difference between PU and Polysteryne fill?
Yes - Pros & Cons to both.
Hi Steve how long have SIPS been in the industry and has there been enough time to do a study on them to see what is the average life of them is ?
What concerns is the durability and shelf life of the glue and the foam cores.
Is there any history of SIPs delaminating in homes or in construction and falling apart ?
I have seen how strong these are on a Bob Vila show they put 4,000 pounds on one panel and it held up.

what types of fire ratings are available with these panels. Are they U.L. listed?
Where's the structural integrity?
1. Is there outgassing? 2. What will termites do to this wood in the coming decades? An earthen or concrete dome will never be attacked by anything. 3. How many decades will the foam glue that seals the panels last? 4. How does this system stand up to extreme heat in a forest fire or next door fire?
They have metal clad as well. Use steel framing and there is no termite problems.
Hello,
I wonder if you can use those panels as slab in a metallic structure?
If yes, How would the junctions be?
Thanks
+ricard gimeno perramon Good Morning Ricard!
Yes, SIPs can be used for self-supporting floors. The thicker the panel the more it can span. Panels are 4 feet wide, and the joints are accomplished with a double-thickness of 1 1/2"-thick lumber fastened together and fitted into the recesses along the edges of the panel.
I hope this helps. Thanks for watching!
Steve
I wouldn't stand on anything like this without trusses underneath.
What's the R-Value of the sips and the weight for a standard 4' x 8' SIP panel?
On average 0.3
How do I buy them in Townsville, Queensland, Australia.
Is it ok to put battens on the inside to create a void for plumbing and wiring prior to plasterboard? For would that affect the fire rating? Also, is wood cladding ok on the outside or does it need fireproofing first?
i’ve seen sips with battens.. I think Kingspan TEK has an example implementation on their website with cross batten service cavities on the internal side of the sip, and brick outer leaf also (instead of siding)
Where do I get 4 x 8 SIPs in N. TX?
i'm not a builder but i see some issues/challenges with these. Running new electrical/cable or even plumbing after it's built would seem to be a major pita. What about wall mounts - ex, tvs? there's no stud to anchor the mount into - and i sure as heck wouldn't rely on OSB to hold it. Then there are building codes. In california , years ago i think i recall a requirement for fire blocks about halfway up a wall. maybe i am misinformed as it being an actual requirement. But speaking of fire, is the foam in these panels flammable? more so than traditional insulation?
what about plumbing? still haven't found a simple solution other than tearing up the panel and patch?
Ease?
Well if you have a crane, and electrician on site, at all times.
Have fun playing with all the foam sealent.
The out come can be good.
Air to air ventilation is necessary.
Things have changed since I used these systems 25-30 years ago. I hope for the better.
Roofs over heat killing shingles, even with the vented panels . Have fun. Chris
Sorry if this sounds really dumb, but I am currently writing my uni assignment. I have to advise on a building which could be used for emergency housing. It must be built on site and must be able to withstand extreme weather conditions. I would like to suggest SIPS but would you need cover the sips panels with an external barrier to the elements? If so, what would you suggest? also do these need any steal frame for support etc? Thanks in advance.
DannyRed Hi There! That's not a dum question at all.
SIPs panels function on their own, without any need for structural support in walls. Roofs can also be made with nothing other than SIPs. A weather barrier is required for SIPs made with oriented strand board, but SIPs are also made with plywood. These would need no exterior protection in an emergency situation because uncoated plywood SIPs are even used for buried foundations. My contact in the industry is a guy named Jeff Taraba. He owns Thermapan and you can contact him at jtaraba@thermapan.com.
Does this help? I hope so. Please let me know.

***** I really appreciate that Steve. Thank you very much, you will be referenced in my assignment!
Can someone comment on the the strength and longevity of a home built using this technology vs homes built with traditional technologies.
hello steve, is it possible to use concrete foundation for SIPs house
+Yoonis Mohammed Hi Yoonis!
Yes, it's certainly possible to put SIPs walls on a concrete foundation. I made the building I'm in right now that way.

how do these houses stand up to hurricanes what is the wind rating? lets say the house is bult to code in florida what can it take
Several SIP-built homes were knocked off their foundations in Louisiana and Mississippi during Hurricane Katrina. The homes were found, more or less intact, several miles from their foundations after the hurricane. They had floated away from their foundations after wind and water wrenched them off the concrete slabs.
I also have a friend who has a SIP-based home just north of Lake Pontchartrain whose house has two large trees fall on it during Katrina. Limbs did puncture the roof but damage was minimal. The trunks snapped upon impact with the roof. These were two pine trees with base diameters in excess of 20 inches. The technology is extremely strong.
There were two ways to prevent this. 1. Better anchoring to the foundation. 2. Better house design, e.g., a dome presents so much less wind resistance than a box that they stay put in 150mph winds. They withstand F5.
Don Duncan I’m not providing these as an example of a SIP vulnerability. Quite the contrary! The OPs question concerned SIP survivability in a hurricane. My response was to illustrate the SIP technology was extremely strong and survivable, even if, in one case, the House was torn off its foundation or in the second case, when extreme winds blew down a very large tree onto the house. In both cases, a conventional frame house would most likely have been destroyed. Both of these houses were very near the eye-wall of Katrina as it made landfall on the MS/LA coast. I viewed both of the houses a couple of days after Katrina hit, everywhere around them the was pretty much catastrophic devastation for stick-built houses. The only other home construction technology that demonstrated similar survivability was concrete home and many of then lost their roofs.
In addition, I visited the second house a year after Katrina, after some normalcy had returned. I was also impressed how cool the house was with very minimal A/C, how quiet it was inside despite truck traffic outside. If ever I build a house, I will utilize SIP construction.
Great video Steve.
I like the SIP panels. I would definitely build my home with this product. The only improvement I would make to this product is; I would sheath the exterior panel with Zip System OSB Sheathing, for both the walls and roof. I imagine this would greatly increase cost of the panels, but a man can dream.
BTW: Did you use post and beam framing for your workshop, to accommodate for the SIPs?
+byron simon I watched a few videos on the Zip system... I agree. I would be prepared to pay a premium for that if something like a SIPS with Zip System was available in Australia.
Eco panels in Mocksville NC has just what you are looking for.
+Steve Maxwell Two questions please:
1. Website Vertigo: I saw this in one of your comments: _"For construction, woodworking, renovations and tools, drop by for a visit at __stevemaxwell.ca__. Homesteading stuff is at __www.realrurallife.com__"._ And somewhere else, a suggestion from you for people to sign up for newsletters at a different website -- baileylineroad.com. How is that third website different from the other two?
2. DIY SIP construction: Have you looked into or have experience with making your own SIPs? By that I mean, buy plywood, foam, and adhesive; and then find a way to paint on the adhesive and weight down the assembled panels until dry. Might be more cost effective, maybe for small projects like outbuildings, etc. Don't know as I've never priced SIPs.
Are these panels approved in Bedford, VA, or any where in Virginia?
+Coral Rock Plumbing Inc. ...Im sure they are... ACME Panel Co.located in Radford Va. will give you info.
How long before this foam material breaks down especially in a very hot state etc
Hello Hard Truth!
SIPs panels have been code approved for 50 years, including for hot climates. Here where I live it's not a hot climate, but in the summer my all-SIPs roof on my workshop gets hot enough to fry eggs on. You simple cannot put your hand on the roof it's so hot, with the only thing between the shingles and foam is 7/16" of OSB. Things work and last fine, even when the foam is super hot.
I hope this helps.
Bye for now,
Steve
@@SteveMaxwellHowTo thank you for taking the time to respond
Problem is even small mistakes lead to big problems. Small seal gaps can lead to structural failure.
Where you get your pannels? What company? Thanks
How is it adding to the building cost when they use less wood less man hour work less over all labor less material you know as well as I do that damn foam isn't more expensive than trust or joist
I'm a big fan of SIPS and I believe that they are the future of housing. I still have some concerns though. I don't know if other Australian RUclipsr's can add to my comment. My concerns here in Sydney would be termites. I don't know if termites are a problem in Canada or not. They can be an issue in Sydney and especially in the warm Tropical areas of Australia. I'm referring to Termites attacking the plywood of the SIPS panels. My other concerns are Fire Resistance and Acoustic Performance and moisture. How do SIPS panels perform as far as sound insulation is concerned Vs stick frame with say rock-wool sound proofing batts. How about moisture sealing of the plywood? Vapor sealing etc. Those are my main concerns. Other than that I'm a 100% true believer in SIPS. Especially if I lived in a very cold climate. Do SIPS constructed homes 'breath' well?

What is double glazing?
Thank you.
Double glazing is two layers of glass in your windows as opposed to a single pane.
they are strong and you can opt for metal skins or plywood
except the fact that if you get a leak the wood leaks and the foam gets waterlogged adding to the weight you have no solid framing strength and your house breaks an falls apart.
Pretty sure the insulation in the panel - what you are calling the 'foam' - is inert so can't absorb water.
what happens when the glue holding the plywood and foam together degrades over time ? it is hard for me to trust in just glue holding plywood and foam together. id like to know more about how the bond is made.
and the fact that if you get a leak the wood leaks and the foam gets waterlogged adding to the weight you have no solid framing strength and your house breaks an falls apart.
This might all be true, but I see two major problems with this system. One, How would this system hold up in a fire? I'm guessing not very well because the heat of the fire would cause the insulation to separate from the panel making much of the structure very unsafe to be in or to have fire fighters come remove you from it. Two, what would a flood do to this system? I'm guessing the flood waters would cause major damage to a system like this vs. conventional stick framed buildings. Imagine trying to replace a whole panel vs a sheeting and dry wall from a flooded house. I believe the flooded SIP house might even be totaled after a flood and require complete rebuilding. Homes don't just have to provide shelter in sunny clear weather. They sometimes have to save you from the harsh elements. This SIP house would be like trying to find shelter in a large foam ice chest.
True true true. Ive been a mechanical contractor for 20+ years i love the idea of higher r value walls but not at the expense of strength and safety. Nothing has changed my mind from stick frame with spray foam, or formed concrete with the insulation built into the cast. The sips structure at the end also would not do well in high winds either.
Dunno, compared to concrete houses, both sips and wooden frames look the same in terms of structural resistance, but i can appreciate the modular nature of sips
I think it would depend on the fire treatment of the plywood and the air seal of the house. A tight envelope might prevent a fire from spreading by using all the available oxygen. With flood damage it would be dependent on how fast you dried it out. We're dealing with flood damage right now. Our neighbors with sheet rock have had to tear out everything that got wet, but our wood paneling has been fine, and so has the foam. Regardless it would require mechanical ventilation
Love your video. One thing I would disagree on is field cutting all doors and windows in the field verses having it done in the factory. Especially for walls of windows in a great-room where engineering/sizing of posts and headers is required, this would be advantageous to put the liability back on the SIP manufacturer. Keep up the great videos.
Mike Dandar Hi Mike! Thanks for your note. There are no SIPs suppliers that I know of in my area that deliver read-cut panels, but that's not as big a deal as you might think. Cutting on site is pretty easy, and all the details need an engineer's stamp before you get a permit anyway. I have heard of pre cut SIPs in other places, but never worked with them.
Do you have a building project in the works?
Drop by for a visit sometime at my online destinations: @/stevemaxwell.ca and Bye for now, Mike. And thanks for watching!Steve
Hi Steve - and all - actually we in Ireland deliver all panels with opes pre-cut: cutting them in the factory is the only way, and it's done on a big bed (16m x 4m) CNC machine. For what it's worth we only use 15mm OSB3 to both sides as for very large panels (our biggest is 15m x 3m), 9mm/11mm isn't rigid enough for onsite handling and shipping. John Moylan, SIP Energy, Ireland.
It may be quick and easy for Steve, and he makes a good buck quicker, but it's not a better built home for the consumer!
Something worth while, is worth while because of the time and effort put into it. This is a home you may live in for 30 years or more. You want it to be a good home. No studs 16" on center, and you call that strong? Sometimes tried & true has proven out to be better than "New & Improved." Ask a contractor how he would build his house, or have him show you how his house was built...
There are manufacturers that offer the SIPS with 16"OC studs.
Can you make me your affiliate in the Philippines? We need the technology to build strong houses because of the frequent typhoons that visit the country/
Good Morning Jesse!
Thanks for your note and for watching. I think SIPs would make a really great house in typhoon areas. I know of one house in the Caribbean that remains standing after 5 hurricanes flattened every house in the area each time they came. I don't make or sell SIPs panels, but I can put you in touch with a trusted manufacturer who does. Send me an email at steve@stevemaxwell.ca and I'll get you some details. You might also like to sign up for my newsletter at stevemaxwell.ca
Bye for now, Jess!
Steve
Walls with nothing to hold them in place. I wouldn't put one of these up in a hurricane zone.
i would
So which part of a SIP makes it suitable for supporting a structure, the water-soluble sawdust on the outside, or the coffee-cup material on the inside? And I guess in this perfect world, no one needs to run wires or plumbing...
He is all talk but till i see these homes being testing in real life over 20 years.
Yes Ive wondered about the longevity of super insulated houses. I doubt they will be around in 200 years like the houses Ive lived in.
This guy must be a SIP salesman. I don't build with flake board. Moisture makes it come apart in time. Build with plywood. Any builder will tell you that. A good realtor will also tell you that a plywood home sells better and is more structurally sound than a home built from flake board. Al little more expensive, but well worth it down the line thru the years. If you build too tight with no air circulation, you will get dry rot. A faster build might be nice because you get in your home quicker, but faster does not always mean better...
Good Morning Woodrow,
No, I'm not a SIPs salesman, and no, you don't need to build with "flakeboard" to building with SIPs. You can get SIPs made with plywood if you want. There are even SIPs panels made to use underground as a foundation wall in place of a masonry wall. Just so you know, though, OSB (what you call flakeboard) these days is highly resistant to water. I'm personally not crazy about OSB, but it does stand up to water surprisingly well. I've submerged the stuff for days as a test and it's just as strong as ever. The main benefit of SIPs is greater strength than frame construction and better energy performance. I know of a SIPs home in the Caribbean (made of "flakeboard"), and it has been the only building standing on this island after three hurricanes flattened every other building with each storm. Also, side-by-side tests of a SIPs home right next door to a frame home (both built to code with identical floor plans) showed 50% less energy use than the frame home even though both have the same R wall in the walls.
Thanks for watching,
Steve
Looks like an electrician and plumbers nightmare
Good Morning Josh! Yes, you'd think so, but it's actually quite easy to run pipes and wires. The key is to think vertically not horizontally. Running pipes and wires through floor and ceiling spaces gets you where you want to go in the building, then you simply drop down or come up with the pipes and wires. SIPs panels can have vertical channels cut in them without diminishing strength. I use a router to cut grooves in the OSB, lay in the pipe or wire, then foam over the groove. It works quite well. I hope this helps. Thanks for watching! Steve
Audio issues in this video are distracting from the content.
sips kill fire fighters
4chencookiiz I don't believe this is true. We tested an ICF house, and found when it’s closed up, fires inside just don't spread, eliminating the need to fight the fire in the first place.
3 times stronger is 200% stronger not 300%.
Poor sound
wayyy too much camera flip ><
Yeah whats up with that camera flip?
Omg right?
I hate a liar
Nice video but terrible editing. There is nothing gained by using those jump cut profile shots.
Hi berglerlemur,
Yes, I'm not crazy about the jump cuts either. The editing was done by my son when we was a teenager, and I wanted to give him some creative control over things. He's older now and quite an accomplished video editor with lots of happy clients. He's moved away from the jump cuts ;-)
Take care,
Steve
+Steve Maxwell it's a very good edit for a junior. I can definitely see why he's done well.
theres gotta be a downside
Yes, there is a drawback to SIPs. A couple actually. This first is that they shouldn't be exposed to weather for more than a few months. This means that the building needs to go up and get dried in fairly quickly. Another issue is ants. They do love to nest in foam. I understand that chemicals are added to discourage ants, but I don't know if it always works.
Thanks for watching!
Steve
thankyou
These side camera angles are just weird and annoying. They degrade the video.
Hi Mark,
Yes, I agree. This video was done about 6 years ago by my 21 year son. He was just learning the craft of videography then. He's a lot better now.
Thanks for watching!
Steve
Styrofoam is non biodegradable. Its disturbing to see that stuff blowing in the wind when you cut the panel.
Hi Steve,
Most Styrofoam litter ends up as marine pollution. When it does eventually break down it releases toxic by-products. It is made from petrochemicals. Most countries have banned its use as packaging.
I like your product, its a great alternative to conventional methods but I wouldn't like to see it turn into a mainstream solution. Its got a great R rating which is a plus, but that's about it. I don't know where or how you would dispose of it in the future when it is finished as part of the construction. In the meanwhile could you please promote safe and responsible disposal of the waste. I used to work with the product the product here in Melbourne and I regret all the times I let it blow in the wind.
Good luck to you Steve.
cool product but terrible recording! sound is bad can't hear!
Bad audio
Most videos I've seen using using SIPs apply them to a timber frame or stud frame, which is wasteful, uneconomical, and totally misses the point.
these things will bow something awful
Please re-edit your audio. The phase cancellation in this video is dreadful. A single source audio is always better than multiple, out of phase sources. The video is helpful, but the sound makes it almost painful. You’ll get better views if you fix this.
