Had to circle back and thank you for this video! This has got to be one of the most helpful/cost effective tips on the Internet. Worked like a charm even on R-30 bats. Cost me like $20 and saved hours!! Thank you again!
Best I've come up with is my angle grinder with a cutting wheel on it. Neat clean cutting and $12.00 at harbor freight. Compress the insulation with boards and slice through it with paper side up.
The very best ever tip on cutting fiberglass. Even if you didn't have to cut it, it's a nightmare. This reduces things from nightmare to bad dream you can handle. Thanks! =)
Thanks for sharing this! This works amazing! I was able to take the insulation to the wall, hold it in place, and cut it to length without measuring. I'm surprised they don't make a commercial product like this just to cut insulation.
that's a pretty clever idea. I wouldn't have believed it until I saw it in action. Seems to make a nice clean cut. For some strange reason I'm craving a turkey sandwich. thanks for posting.
haha I just recently re-watched this video and realized I say awesome way too much but I was just super stoked that day because it made fiberglass go a lot better. Lol. I can see where the craving comes from but maybe after doing fiberglass you won’t be hungry 😁
Hey thanks dude! This looks way way easier than the scissors I’ve been using. What is really bad is cutting a bat of 9 ft long lengthwise! Can’t wait to try this!
You’re welcome! Yes it cuts like butter 😁 especially the length wise cuts are a pain normally. Have fun! It’s fiberglass so anything that can make it go better is good right? 😊
Dude I clicked on this video thinking “wow what a stupid idea” I completely take that back and willingly say that I judged too quickly! That thing looks great. I’m about to insulate my barn and I’m going to break out my wife’s turkey carver (sneakily so she doesn’t see it) and thanks!!
I just started this job in the garage and found right away, my knife wasn't going to "cut it". Fang for a few hints/ideas, I've settled on this. As with most anything, sometimes the right tool is off in some other drawer. Thanks.
My wife gets mad when I use her good scissors, pots and measuring cups for doing things other than kitchen work, now she is going to hide the electric knife too.
I bought a hamilton beach electric knife at my local wally world just for insulating my garage, I can't even begin to figure out how many times that $20 knife paid for itself just in time saved!
@@SmartEasyDIYer used a couple coupons without issue but today had an online order canceled. Called and they said they couldn’t see a reason other than “corporate review”. Have you had any similar issues?
I need to cut insulation to fit inside a narrow bay in an open ceiling. Using this method, the facing paper also gets cut and one side can't be stapled to the joist. How would you secure the batt to the ceiling after cutting this way?
You can get insulation support wires from Lowe’s or hd made for holding it in place. You may have to cut them down some too if your opening is undersized. If it’s just to hold it for a bit till the drywall is in you might get away with cutting it oversized so you still can staple some paper, otherwise the wires might be the best thing.
Right on! What is funny about this vid is that the electric knife he’s using is rated one of the worst by America’s Test Kitchen (PBS) for carving food. That said, it apparently was made for this job! Awesome! So- if your house has the Cuisinart knife, no problem! ;-)
Yeah but it gets dull really fast and then just tears the paper. You can do it if you have lots of blades. I’ve done it that way a lot too till I discovered this and how easy it is. Depends how much you have to do if it’s just a small project knife is fine but for anything bigger I would so recommend this. Myself I’ve done enough I hope to never touch fiberglass again if possible. Lol
Use a yellow Olga long blade that has snap offs, one blade would last you all day, as an insulator I would never use that electric knife in this video, I'm sure it works but you can't carry that in you're tool belt all day
@@SmartEasyDIYer they do and amazon has it but then when you need it 2 years later the battery will be junk, on slow use tools Im going back to plugin. I can leave them in a box for 10 years and theyll still work once pluged back in. Seems lithium or old nicads just go bad over timeand are so expensive.
I know the pain you are going through with this type of insulation! Looks like a nice tool for this type of job. You're going to tick off the kitchen folks as Dewalt and others are going to start selling these for 500.00 + dollars. ;) .. All kidding aside; nice find..
I bought one of these, not sure if I will use it on insulation in the future or food; time will tell. I guess they had an issue with the case cracking, I probably won't unbox this for a year so give me an update as to whether you see this issue or not. I know you will stress this unit so let us find out if they resolved the issue. Probably would have had a 5 star review otherwise. Walls open put in more electric then you think you will need. Not rich but I buy things and when I have time I unbox and have fun with them. I have about ten right now from kitchen stuff to woodworking latest acquisition Dewalt 745 in which I would like to make a table around which will come sooner then later. Your place looks like it is coming along very nicely, keep up the great work and give us and overall view of your work and update. Gerald
Ok awesome I hope you enjoy using it. This is actually my second one. I have one at work and one for my own projects. I’ve never carved a turkey with it just insulation but they both have held up well so far. So yeah it sounds like you have a lot of projects are there certain ones you like working on in particular? I have so many videos to put together of the building process so I will put more up as I get time. :)
@@SmartEasyDIYer ts a good idea, dont get me wrong. I work in insulation. I've tried everything. But the long snap off razors always prevail. I dont usually even snap them just change the blade out every 1 to 2 days. They also trim spray foam very well and can cut any glues off the floor. More handy than a regular razor.
The only thing you making veido need to know is LESS TALK. just show us tell us what we need to know. pictures speak louder then words good lord on and on.
This is genius. I absolutely hate dealing with insulation. This saved me hours. Thank you!
You’re welcome. I’m glad it worked well for you! I dislike insulation too. Lol

You’re welcome! I’m glad it worked well for you. 😁👍
By far the best way to cut this stuff. Bought a Black and Decker one off of Amazon for $20.
Thanks! I’m glad it worked well for you!

"saw" it in action
@@tylerstephens8542 lol
OMG!! Why couldn't I have seen this a week ago.. been dealing with the same JM R13 for 2 days with a utility knife. Next job this is coming with!
It does make it so much easier and more enjoyable, if fiberglass can, in fact, be enjoyable. 😂 thanks

Haha awesome thank you! Yeah you best do it sneakily. 😉 good luck.
buy her a new one, cheapo.Use the old one on your project. Best of Both Worlds. Good luck.
Just did this today and it worked great thanks 👍
Awesome! 😁

Haha yeah sometimes the knife doesn’t “cut it” 😁. Good for you! Good luck with your project! Happy itching.
My wife gets mad when I use her good scissors, pots and measuring cups for doing things other than kitchen work, now she is going to hide the electric knife too.
😂😂 I know how it is! Just take it and act innocent. 😇
Ask8ng for forgiveness is much easier than asking for permission!
That’s for sure! 😂
wow cool, great tip!!!!
Thanks I’m glad if it helped.
The knife is a great tip- thanks
You’re welcome.
Wish I had seen this last week.
Me too! Maybe next time. 😁
how much can you cut fiberglass before it goes dull?
I did my whole house and it was still cutting ok. I could tell it was duller but still going.
I bought a hamilton beach electric knife at my local wally world just for insulating my garage, I can't even begin to figure out how many times that $20 knife paid for itself just in time saved!
That’s great!
Thanks for the Lowe’s coupon
You’re welcome!
@@SmartEasyDIYer used a couple coupons without issue but today had an online order canceled. Called and they said they couldn’t see a reason other than “corporate review”. Have you had any similar issues?
No I never have. Hopefully they sort it out.
Wow mate !! Amazing idea !!

Does it work for unfaced fiberglass?
Yes it should.
Great idea!
Thanks. It’s the best way I’ve found so far
saved my butt, doing my own install too.
Awesome. Good luck insulating! 😁
Right on! What is funny about this vid is that the electric knife he’s using is rated one of the worst by America’s Test Kitchen (PBS) for carving food. That said, it apparently was made for this job! Awesome! So- if your house has the Cuisinart knife, no problem! ;-)
That is funny I had no idea about the food rating. Yeah maybe it’s destined for cutting insulation! 😂
ITS LIKE MAGIC.
🫣😁👍
Good video man awesome
Thanks!
why is the insulation over the studs?
That’s the way it works with the kraft faced type.
Called Face stapling insulation goes between studs then u take the edge of the paper that has a flap n staple it to the studs
Just use a utility knife? And sharpen it up really good?
Yeah but it gets dull really fast and then just tears the paper. You can do it if you have lots of blades. I’ve done it that way a lot too till I discovered this and how easy it is. Depends how much you have to do if it’s just a small project knife is fine but for anything bigger I would so recommend this.

Maybe they have a cordless one by now. Lol

This is a superb hack. However I need it now so I'm going to the thrift store to see if they have one. They always have ten or more😅
Thanks. That’s actually a great idea and who cares if it’s well used. That way you won’t get in trouble for taking your wife’s nice one. 😅😅
I started cutting mine (R-19) with a gigantic pair of hedge trimming scissors.
Haha that may work too!
Smart Easy DIY just found your channel. I appreciate everything on here. KEEP GOING BRO!
Thank you! I appreciate that
What about all the fiberglass filaments you're agitating into the air?
It does it just from handling it too. It’s good to wear a mask.
Don’t ask your wife to borrow anything!

A long retractable razor blade will do it all with 1 cut. About 10 times quicker than this method. I want to cut things once in one spot not twice
Yeah but my experience is they dull very quickly. If you’re doing a big project anyway. I went through too many knives
@@SmartEasyDIYer ts a good idea, dont get me wrong. I work in insulation. I've tried everything. But the long snap off razors always prevail.

Cool thanks for the info. It’s probably faster since you do it every day. 😊
With Stanley knife cut much faster i nice cut. Unless tool waist of money. Sorry
If that works for you. I prefer this over Stanley knife when possible but that’s just my preference.

Wear a mask man pls
I do normally but I didn’t want to just for the video demonstration I would’ve sounded muffled. Lol
Great idea!
Thank you!
