"Viral DIY: Insulate Your 16ft Garage Door for $100! Watch, Save, and Share the Secret!"

⁠job completed while I listened to NFL division games on radio. I went slow and careful and kept getting happier and happier. It was about 31 deg out when I was doing this. I was running a small electric oil radiator on hottest setting before starting and as I completed job I could feel the heat holding better. I’m very interested in this mostly for sun here in Louisiana. Gets HOT. If I can keep my garage cooled off 7-10 degrees cooler I’ll call it a big success. My garage door is 18’ x 8’ and that’s a LOT of surface area for heat and cold radiation. That’s a project I’m happy to complete. My receipt for the job was about $110 do 5 insulation panels and I had a bunch of AC tape on hand so only had to buy one roll too. Anyway my job didn’t come out near as “pretty” as yours but it will be good and functional! PS - I shoulda bought that razor knife. I used a long carpet knife that cut 3/4 way through and my stuff snapped good like dry wall but left a bit jagged edge. That’s alright though doesn’t affect functionality! Cheers and thanks again. Job done thanks to your pushing me with your own video!

Looks good, Dean. We live in Australia, so our problem is keeping the heat out in Summer. We insulated our garage door when we built our house 5 years ago and the builder thought we were crazy but our garage stays reasonably cool. In comparison, our son's garage, which is not insulated is like an oven.

I am a 69 yr. old retired teacher. I moved into a smaller home in Houston with horrible insulation. My garage was so hot that the food in my pantry melted! I have used these insulation sheets on the garage walls. Big difference. I decided to follow your excellent instructions for insulating the garage door. Mine didn’t look as nice as yours, but it did work nicely. The cost has gone up, of course, so the cost was around $150. Thank you!

Also, put plywwod under board you want to cut so you don't cut the other boards underneath accidentally. Quilting for thirty years has taught me some lessons.

Things you didn’t know you needed. This is the answer to my freezing garage. Great video.

We did this and it made a huge difference in winter/summer temps in garage. Highly recommend it.

LOWES sells garage styro-foamed panels with white insulated taped backing already on. Paid 100 bucks for 2 boxes of 8 panels that took me less than an hour with less fuss. Enjoyed your clip btw. 😊

I don't even have a garage but I enjoyed learning about this material and how you did it. 😊

While R-4 is a lot less insulation than most of us have in our walls, it is almost infinitely more than the R-0 that was there before installing 1" foam board. Thanks for the video !

Thank you so much! I bought the supplies and insulated my garage doors last weekend. So happy with the result!

I have been wanting to insulate my garage door from the heat for a few years now from the extreme heat. This looks easy and affordable. A few years ago I insulated the ceiling. I couldn’t believe the difference !

What an excellent presentation. Being just south of Austin, this should help keep my garage cooler in the summer and warmer in the winter.

The top panel is longer do to the curve of the track. If it was the same length it would not seal along the top. That is how it was explained to me when I was younger. I worked for my father, who installed them.

Dean, you really did a great job with this video. Your explanation of the technique and the various tradeoffs is well done and incredibly helpful. Best, Chris

Never felt so engrossed into any instructional video! Thank you for such detailed video, Dean.

You da man Dean. I’m doing this job tomorrow here in Louisiana. Should have done this five years ago. I need it for both weather extremes here! Thanks for the great tutorial. Nice to have you talk through the variations I have on my own door! I owe ya a snort of bourbon neighbor!

Well done video! By sharing what you've learned you will keep a lot of us from making mistakes and wasting materials.

I literally just bought this exact same foam panel from HD yesterday, but I was using it to make an insert for my fireplace opening to block the cool air. Now I have a reason to buy more. Thanks for the video! 👍🏽

So glad this showed up in my feed! I've seen other similar videos in the past, and you've finally given me the nudge to do this. I live in Houston, and from reading comments, the benefits of being able to block out heat will make this a wonderful project, much more than the very occasional cold that we get. And this is cheap enough that I will plan on insulating my attic as well. Thanks much!

Thanks for the info I also live in Texas. The only thing I’ve changed is when I cut each panel in the middle I cut it at a 45° instead of straight 90°. Makes putting them all the way into the lips easier
