How to Insulate Your Garage Doors and Save on Energy Costs! 

Alright, the follow-up videos on the results, FAQ and 10-month update are posted. The links are in the description, enjoy!

Haven’t even watched your whole video yet. Had to give you props for the time stamps. Wish more you tubers thought like you

Your attention to detail is astonishing. You even correct your grammar in your editing. 😂 That’s worth admiration and praise. Both the insulation job and video production are of very high quality. Thank you.

Dude, you are an absolute perfectionist! Watching you cutting the pieces off the masking tape to make everything look neat is so satisfying. Thank you for such a detailed video. This will help me with my garage door project.

For anyone doing this: You're much better off using 1" to 1.5" RMax polyisocyanurate foam with the metal foil on both sides. It's more expensive than EPS foam but has double the R-value. And in such a small depth of a 1.5" wall you will really need it if you expect it to really help. That and having a foil layer up against the door's sheet metal will greatly GREATLY aid in reflecting heat or cold back out while the inside foil layer does the same. Using white EPS foam and then having to add an additional layer of bubble foil (to inside only) will still only give ~1/2 the R value and again, if anything, the foil should go inside against the door's sheet metal for optimal heat reflection. If I was using EPS then I would at very minimum buy a roll of attic foil (it's ~2mm thick) as install that first. But again, the actual metal foil on RMax thermasheath-3 is superior to using raw EPS. As they say... you pay for what you get.

Nice, clean install and I appreciate the attention to detail and Overkill. Can't wait to see the 280 completed! 👍

Would love to get an update to see how it's doing for colder months. I like working in garage in the winter but man does it get cold. Thank you. PS really enjoy how meticulous you are

I love how thorough you are on/through out the entire project, way to go! Good video.

Just get foil faced rigid insulation and cut to fit. that way radiant barrier is already on foam insulation. comes in 3/4", 1", or thicker depending on your door

I've watched several videos on the process of insulating a garage door. This was by far the most informative! I was torn between the two techniques and I really appreciate that you showed the difference between the single and double layers. This was very helpful and I really appreciate you putting this video together!

I did this three years ago. Worth it!

I’m an over kill type of person too. Plus for esthetics I think I will do both. Thank you for this awesome video.

Time stamps on video were helpful when replaying and your detailed explanations were great! I subscribed due to how well this was put together. Looking forward to more videos

This video helped a lot I really appreciate it also your video quality and editing is great

Love the way you edit your videos with the music choice on your time lapse. 👍🏼

Great video. Kudos to providing detailed info, amazing attention to small details, and your sense of organization. Saw that you even made a video of your garage organization. Looking forward to watching more of your videos.

You can buy Rigid Insulation foam boards that are essentially the same thing as this Garage Insulation kit, just at a fraction of the cost. Especially if you're going to be cutting to size anyway.

This doesn't feel like overkill. it was exactly what I was looking for!

Wow thank you for this video. I did the cellophane insulation like you and fortunately I did not have to use tape as I have a standard size garage door. It made an incredible temperature difference as mine is west facing and the summers get pretty hot in this part of California.

Thanks for taking the time to shot this video.......my garage is roasting as it gets morning and midday sun. You inspired me to insulate!

Thanks for the video. You have the most organized garage I've ever seen.

Love the garage videos man! I’m not much of a restoration guy but I’ve been subscribed since the first garage build video and love seeing the garage build and welding content. Honestly even the restoration stuff keeps me entertained. Keep up the good work!

I subscribed because your video is well put together, you explain things clearly and thoroughly and most importantly... YOUR MUSIC IS NOT ANNOYING AND IS PLEASANT!!!! Nice Vid!

Very detailed tutorial. Thank you!!!!

Homie great video! This was exactly what I was looking for. Big ups!

your work is so clean!

Good job. I also like the classical music. Very relaxing.

“Reverse privacy” Cracked me up! Great video - thank you for the info. :)

Excellent job. Thank you 🙏

This by far is one of best DIY videos I have seen... Great for us perfectionists. 😁... Love the Datsun 240 Z (or 280).

Excellently presented and described. Thank you!

I really enjoyed this and will be doing it myself

Great video. You are an intelligent RU-vidr. You explain what your doing very well. Can't wait to watch other videos.

Iam so amazed and impressed. I like the discipline and attention to detail. I think this is a great video and it’s organized very well.

Idea, instead of using yellow tape on the top window panels,you should use double sided velcro stripes; You can take off any of the top window panels in the day, so you can see on the outside .

The interrogation garage!!! Looks great man thanks for the footage

I like your meticulous attention to detail and overkill. I'm a lot like this myself. Great job. I am interested to see the second video showing the temperature readings. Thanks for posting this. Cheers

Great video. Just what I needed to know before I started my own garage project. Much appreciated.

Excellent job and informative video, thank you!

Looks great, thanks for the breakdown

Really cool video. Excellent job and explanation for any personal idiosyncrasies...that effect cost outcome, etc.

Looks great and what a difference! That's going to be my next project.

Great video! Really good job walking through the steps. Subscribed!

This was great! Your process and detailed guidance is terrific. We were looking for a tip to insulate our garage for our freezer and to play ping pong. Thank you!

Very cool man ( no pun intended), going to give this a try over the weekend!

WOW! What a beautiful garage you have made. I'm just starting wood working. I Love the shelving you have. THANK YOU FOR THE INSULATION TIPS AS WELL!!!

Erik Satie - Gymnopédie No.1; Nice choice. Also very nicely done insulation tutorial with temp. results. Thanks

Thanks for sharing .

Excellent video, it’s practically storyboarded. My questions were answered and thats because of your due diligence. Great bluetooth monitor btw. We have used the same model for the past 15months in the baby nursery. Based off of the timeline you stated, 3weeks for one video is impressive. Its probably closer to 5weeks between ordering materials and post production… Subbed…

Thanks brother! This helped a lot .

While living in Vegas this was a normal process. The problem was locating the foam. It had to be ordered in 4X8 foot sheets from the hardware store. I used a hot wire machine to cut it, I just happened to have the machine. The process is good for both heat and cold. Yes, it freezes in Vegas too, it even snows! The blue or pink foam is a closed-cell foam and even better but it costs more.

I bought Reflectix and tape 6 weeks ago; just wasn’t sure what to do. This is great so thank you! We, too, get the summer heat (southeast PA) beating on not one but two sliding doors into our living room. I like the idea of using Gila Window Film. I’ll give that a try in the spring.

Great video!!

+1 for using a nice piano montage music, and not the typical youtube soundcloud dubstep.

Great video! New sub and like here. Thank you for covering up those windows. That would have absolutely driven me crazy. Your time stamps, links and chapters. OMG.. top notch. Thank you so much for the time you put in.

To get privacy in the evening, you’ll need to install external lights above the filmed windows that are bright enough to reflect off the windows, or have lights indirectly/directly pointing at your windows. You’ll need to play with placement to make it work correctly.

I'm definitely doing this !...thank you, greetings from southern Tx

Nice job thanks for the details !

Yeah - kudos for time stamps. I will look for other videos of yours. The overkill will come in handy when you heat your garage, as it should reflect heat back inside. 👍

Just watched both videos about the garage door. Appreciate the pragmatic approach to this! Also have a '99 Miata, so you can bet I'm a new subscriber. Thank you!

Love the detail

I'd suggest after cutting reflective panels to size, and double check fit, use 3M Super 77 spray adhesive. This will insure the panels stay put, and glue to the foam. You won't need the tape, but can carefully install to seal the edges if you like.

Good informational video and relevantly presented. Best wishes on your Datsun Z restoration.

💥 FYI: You would have better results if the reflective layer was installed underneath the foam layer. 🤑🤪 EXCELLENT video, thankyou for sharing. 👍

Good demonstration. The radiant barrier should be directly on the door to radiate the heat. Foam insulation can be over the radiant barrier

The foil tape is designed for the high heat of heating ducts... I would recommend it over any other for this.

Solid video. Was thinking how to do this before the Texas summer descends.

Wow, nice job!

Love the Sonett!!!

Nice job👏👏👏👏

R tech 1.5” foil backed foam insulation panels at HD fit most garage door depths, cuts with a circular saw, table saw, or 3 old school hand saw. Messy but huge money saver. 3 car garage 4 panels high takes about 3 hours.

I like that you put racing stripes on the inside of the doors.

Nice video. Still waiting for your update. Thanks

Insulation cleans super clean!!! Awesome video :). I live in Alaska and we get -50 weathers this insulating my garage door would be great but using painters tape might not work too well for me since garage doors gets super cold and tape might just fall off 🤷‍♂️. Anyways keep up the good work 🤙🏾.

Great idea. Those huge clear glass windows are a thieve's delight for all of your tools and stuff.

Looking to insulate my garage. Great video! Thank you!

Me & my g/f used that gila window tint in our old apartment in Phoenix az to save on cooling costs every month, it was the darker tint, the install was very easy we sprayed soapy water on the windows & squeegeed the water off. It was a huge difference in our apartment

great video man.

Good choice on the Bach.

Great video, and thank you for all of the extra details and information. 👍Subscribed.

Nice job and I can appreciate the overkill. And nice touch with the music from My Dinner with Andre.

You earned a Like from the well done insulation. You earned a Subscribe for knowing you can't use an IR thermometer on shiny stuff. I like how you did this. I'll probably be doing my doors the same way. Looking forward to exploring your other vids.

I found the static cling works great

The IR thermometer measurement is a divergent spot, it's not measuring just the tiny laser dot, which is just for aiming purposes. Need to get much closer or use a larger target tape. For an accurate measurement you need a larger surface with an emissivity of something around 0.95. You can compare measurements with an actual thermometer to see if the tape being used as a target is suitable.

I've been thinking of doing the same thing to my garage, but for a different reason. During the winter the basement gets very cold since it faces North and is in a constant shadow, especially on a cold night. The bare metal doors suck out any heat. Insulating them in the same manner as you have should make the basement garage workshop a better place to work. Thanks for the tips.

Thanks so much bud this helped me a lot

Oh man that is an awesome car!!!

I use some of the govee temperature and humidity products to monitor my crawlspace humidity. Pretty nice product 👍

Good info. Thnx

Haven’t finished watching yet, but love the 240Z. My dad had a 1971, and I later a 1972 240Z

Thanks for this. I am going to place a layer of reflective material directly against the metal per the instructions. Then place the Celloform insulation. And perhaps another reflective layer on top of the insulation.

Looks good.

Why y’all works so well

Hey guys, I felt like I needed to make a revision here. I don't suggest using masking tape to hold up the Reflectix. It looks like it's coming off in some places that I didn't take care to press it down really well. More of an annoyance than a big issue, but if you're doing this, go ahead and use the foil tape.

You're a perfectionist, just like me 😂 good video!

Came for the insulation info, saw the Z and had to subscribe!

Ceramic film blocks more heat than any film on the market. Easy to apply on flat glass. Overall great video man. Love the way you laid the video out.

great video, i also looked into the polystyrene garage kits. I went to a big box store and found 48x96 sheets of reflective/foil backed polystyrene.

my favourite part of those z cars was the engine, wonderful machine.

I’ve just discovered your channel! Great OCD work on the insulation. You mentioned you wash the floor a lot to remove the dust. Consider painting the (what looks like concrete) with epoxy paint. I did mine on bare concrete and now has very little dust from the floor itself. I insulated my garage doors too but as I’m from the UK, the problem I had was to keep heat in when it’s 0 degrees C outside.
