This gentleman took the time & trouble to make a video to show you how he did a project. Have the detractors shared their experience? I doubt it. Please don't be rude to those who go to trouble to be helpful. And maybe he lives in a cold place and has a heater inside for winter, in which case, the foil faces inside. Maybe you, commenter, live in Florida. This is an excellent, helpful video, clever and to the point!

I just got a house with a huge garage (detatched) that was unfinished and uninsulated that i want to turn into a wood shop... This is the best idea i have seen so far for tackling the door problem. I most definitely will give this a shot when the spring time comes.

Started turning the garage into an outdoor living space Thank you for taking the time to make this video for us all.

JAMES.thank you sooo much,from land o lakes fl.So kind of you to do this.Means a lot to those of us that play drums and to have the garage reinforce and coolor its great.Thank you.!!

Okay,....this was super helpful!!! Geez,. Thank you for taking the time to put this demo together... cheers.

I would’ve known to do this. Thank you so much for taking the time to share your experience; it’s greatly appreciated.

Just a suggestion. I believe cutting the slots in the foam to help install it reduces your R-value. Though not significantly I believe it reduces it more than the method I used. I cut my panels in half using a razor knife and then put the bottom half in and put the top half in pulling the bottom panel out slightly to create a v in the two panels and then pushed the two panels in together and taped them with special tape that is made for these panels. I don't believe the spray-on foam is any advantage at all because of the differing expansion rates of the materials. The properly sized panels with those lips at the top of the bottom and properly taped should hold them in place. It did in my case.

Awesome job! Not only for the task of insulating the door but you filmed, narrated and edited the tutorial. I like this- I’ll check out more of your videos!

Looks good! I'm heading to Home Depot today to buy the same insulation and stumbled onto your video. Answered all my questions. Thanks!

Nice work, last week I insulated my garage with typical (pink) r13 fiberglass insulation rolls, my garage was just studs and siding, I'll be putting up walls soon but I was gonna do what you did to the door first to try and keep as much of the elements out so thanks for your method

put some aluminum tape to seal in each panel on the edge of the insulation boards where they meet the frames of each door panel. this will seal it even better. but good job with the spray foam atleast to glue on those boards.

Super excited to watch your video. Something I put off for 7 years. But found at Lowes a kit and it’ll take 2 kits about $120 to do our door. Your video helped me to have a visual to do it. Thanks!!!!! ❤️

Here at Hunter Door service in southern New Jersey The difference in price of a hollow garage door and a Styrofoam back garage door is between $60 and $80. The benefit is it comes with the correct springs so the door is perfectly balanced and won’t wear the soft plastic gear inside your garage door opener. If you take on this DIY project be sure to put a bathroom scale under your garage door and make sure your door doesn’t have more than 8 pounds of deadweight. If it does then referred to other garage door KZfaq videos on how to balance your specific spring system to accommodate the additional weight of the materials you used in this DIY project.

Did this for our garage when I turned it into a LuLaRoe shop for my wife. Just installed an AC last week and it works great.

I'm watching this video MUUUUCH later since it was first posted, but have already watched it multiple times over the last few months - and this one is simple, and has been the driving force to convince me to NOT go with the kits and opt for this DIY. THANK YOU! I actually missed the little detail of relief cuts completely so thanks for mentioning it as I've seen many (too many) other videos where they don't do that and the foam pops and breaks. I'm super nervous about my measurements given I'm always just a tad off but seeing this, I will deff "encourage" my husband to help me with them as he always manages to avoid assisting my home improvement projects and woodworking then critiques my off angles and sizes. Hope to have as much success as you did, thank you!

thanks for the advice on telling the home depot workers manager about the courtesy of cutting the pieces . also you can often look on your receipt and fill out an online survey about how happy you were for lowes and home-depot worker , and pretty much any place else now a days . its better than yelp reviews for getting your neighborhood businesses up to speed

Nice job. I’ve been wanting to do this for a good while. Georgia summers are brutal and all that heat traps in the garage and really warms up the room above it. Need to get off my ass and get it done.

The video was very informative and your smile was a perfect compliment. You looked like you really enjoyed making this video.

Great that I found your video , just about time to insulate my garage this winter. thank you!

Thank you James. Your instructions were great. Looking into doing this too. Subscribed.

I like that you used foam, and how the line cuts made installation possible for the extra height panels.

Glad I watched, this is how I will do my garage door. It looks professional and should help lower the day time temperatures in my garage.

Thank you so much for this video! Easy to follow, very informative with lots of good tips =)

Very nice presentation. I am glad you took the time to show it to the world.

very helpful video , you have done the awesome job that i been searching and learn to get my home garage door insulation . thank you

I Enjoyed your video. Its nice to see it go up before I take the job on myself. Good job. love the foil look on the inside.

Dude, I finished my mine using your informative video. Thank you very much.

Thank you! Never thought of this. My next project before winter comes.

Thanks for putting the video up! Been wanting to do this for awhile, will be doing it this weekend. Thanks again.

Thanks! This is just what I needed. My garage door is just like yours. Good job!

Thanks for the video, your install is more thorough than others. Wish you would include how you measured for the correct width. My garage door has 1.25" clearance at some points, 1.5" at others.

Thank you Jim for sharing your accomplishment. I have been thinking to do something with noisy garage door. Even though temp insulation is not my need in San Diego but this might reduce vibration noise from flimsy panels.

I love this video clip. I'm going to get my hubby to do it like you did.

Enjoyed watching this project. We will try this in the spring.

Your excellent video was enriched by some very good comments. Most worthwhile watching, Thank you.

Good work, can even hear less echo after the insulation was installed.

This is insulation 101 for me. I understood everything you conveyed and will take your method to see if I can do my door the same. You are a natural instructor. Maybe you can afford to have somebody hold the camera for you? :-)

Great video and good job giving some credit to the dude at home depot. The world would be a better place if more people appreciated others for the good jobs they do.

Looks good to me! I think you did a good job. It certainly sounds like you did a good job. Yup, its good!

Thanks for taking the time to make this video very informative, I may do the same to my garage door as well.

Thank you for sharing!! I saw this other guy and he cuts the panels and slides them in, flexing it was genius! LOL

Simple enough. Great tutorial. Thanks!

Thank you for explaining what you did it was very easy to understand.

I was thinking of doing the exact same thing to my garage door!! Nice job!!

Thanks for the video! It was very helpful! You blazed a trail for me.

Very useful you used a very common method from the aircraft industry . Thank you for reminding me

It also occurs to me that with the foil on the inside, the reflection of your garage lights would add the the interior brightness

Good job and nice and clean! May God Bless you!!!

Thanks buddy this was helpful. I'll be trying it out in my garage . It's like a over In there

Thanks for the video! Very informative and I'll be attempting this soon.

Did this to my garage door. Foil to the inside, foam to the door. I live in El Paso, TX. It has helped greatly with both heating and cooling as my garage is my shop. Before doing this it was almost impossible to work during the summer. Now it is pleasant and cooled with a small AC unit thru the wall.

Excellent work! Thank you so much!!

Awesome diy video. Very well explained seems simple and low cost. Please share more videos of diy like this.

Looking to do exactly this . Appreciate it James.

Great project. Thanks for sharing.

Very clever! Looks great too.

Pretty straightforward! I will try it this week.

Thanks for sharing. Using the foam was a great idea

Very informative, the cutting seemed a bit much; but then again, I haven't gotten to that stage of the installation. Looks great at the end, Hope mine looks as good!

Hey what a great video I truly enjoyed it I have one quick question is that insulation going to be able to keep heat out of the garage

i want to let you know yes i found value in your garage door insulation video, yes sir, thank you, you have helped me

For future reference, when you spray with the Great Stuff foam, you should hold the can upside down.

If you can get Thermax insulation the R value is 6.5 per inch. Made by DuPond and Dow Corning. Waterproof. Aluminium on both sides. Good job on the garage door!

a DIY i could actually do myself for the first time in my life lol!

Great idea, Thanks so much I will do mine the same way you did .

This was helpful because I’m looking for the most reflective yet simple way to do this on my own Thanks

Always wear safety glasses when using Great Stuff. It has isocyanate in it and will blind you if you get it in your eyes.

Nice work. This is gonna be my next project. Thanks!

The garage door installation video is Super! Thank you very much for sharing the information. I am definitely going to try this on my garage door. I think that you are very smart!

Nice Job, thx for the spray foam tip !

Thanks for sharing. This is a great DIY. I will try this out. I have two garage door to door. Not happy about that. lol

Great video and instructions. Thanks for making it.

As per your request, yes I like your vid; and it gave me some good ideas and a starting point. I have to control the climit in my garage this summer as I have several mining rigs which heated my entire 1st floor by just using the HVAC fan to circulate the heat all through the winter, and not only did it offset the normal billing average from last year, but I saved on or about $65.00 per month. My rigs are whisper quiet so they severed a dual purpose. I have one garage door and a window I need to insulate, and the A\C unit will also go in that window. I wired a 12X30 detached garage with 120v & 240v, and was going to set that building up to build a mining farm; however it has a fiberglass roll type front door and figured it would be easier to insulate the traditional style garage door. I will use the 12x30 as a workshop, as dust and heat are the primary reasons electronics fail. Thank you for sharing brah, I wondered how the relief cuts many only minimally affect efficiency? However if you use the expanding foam in the relief Cuts before you do the flex insertion possibly that would just mitigate it completely? Very Respectfully, WX2

Came out great, nice job, you should be proud!

Thanks! Next Project! My bedroom is over the garage...winter is the worst!!!

I’ve done mine two different times and I finally gave up on it but I haven’t tried this way but I will! Ty

Great tip , I'll be doing the same thing , thanks for the info , Houston Tx

Using those relief cuts is a great tip.

This great. We want my son to convert th garage as his personal living space. I think this going to keep the Canada winter coldness at bay.

Great tutorial. Thank you!

Great Video and Great Smile! Now its been 3+ years since you did this video, how is everything holding up? I live in NJ and its getting cold and it will probably get really hot too. I was wondering if it made a significant difference after your did this install and if there is anything you would have done differently.

What a super idea. Got to try this.

Scraping the driveway is genius. I have been using my hands

Outstanding. Helped bunches

Very nicely done! I have bad knees... I think, I'll do the top to rows and then raise the door to do the next two rows without having to squat, stoop, or kneel!! Just a thought!

Thx - well done, James!

That looks really nice Great Job !

I like your method. I hate using the foam stuff but I might. Going to do mine.

Wow this is great!!!! It looks nice and clean

Great vid! I used the Reflectix to insulate the interior of my work van and it was almost like a miracle for climate control.

Thanks & great video. Thanks for all the tips and tricks you did here too. Wondering if you notice a cooler garage and about how much cooler and when it got cold outside, how much warmer ?

Good job. Where I live all foam board has to be covered with a fireproof material like drywall...which wouldn’t work in this instance. I had to settle for the fibreglass blanket made for garage doors.

Very nice video Thanks for sharing... You learned allot from this, how to cut it yourself, fitting each part in and using the foam spray as adhesive,,, We can do most things ourselves... but being safe is No. 1 Please read all directions and watch a slue of You Tubes on the subject and have a call number just encase you need backup.. Good DIYing to Ya.

Great video, information is very helpful. Thanks for sharing.

Great video. Thanks for sharing

Great job! What were the measurements for the relief cuts? I need to do this to my garage too 😊

This video was really helpful thanks !

Nice craftsmanship

Great job. Thank you! Since the foam insulation is sticky, it must help keep the panels in. Do you think the panels will hold without the foam insulation?

Excellent work. I learned something today. Thank you!
