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.

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.

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.

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!

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

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

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.

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

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

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.

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

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 .

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

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

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!

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'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.

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.

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

This guy isn’t messing around.

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

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

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

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.

Great video. You are an intelligent KZfaqr. 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.

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

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.

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.

I stood outside your doors and watched you most of the night. I was wondering if you could see me. The window film is great!

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

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.

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

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

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. 👍

Nice video. Still waiting for your update. Thanks

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!

Would love to see your restoration vids of that Z!

bruuuuuh. this is perfect. the new house we bought has a triple stall garage with 3 doors. the big one has 16 glass panels and the small has 12. our garage faces west and it's a literal furnace in there getting upwards of 130 degrees. after watching this vid, i just bought some reflectix and now i'm considering gila as well.

Excellent job. Thank you 🙏

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!!!

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

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!

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

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.

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

Excellently presented and described. Thank you!

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!

Very detailed tutorial. Thank you!!!!

Thanks for sharing .

Excellent job and informative video, thank you!

Nice job thanks for the details !

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

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.

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

Looks great, thanks for the breakdown

I did this three years ago. Worth it!

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

Nice video - I think you should do a garage tour and go into how you built your shelving.

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!

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

your work is so clean!

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

I think you put the radient barrier first to reduce infrared radiation, then the foam to slow down heat transfer for best results. But definitely good you covered the windows with that radiant barrier.

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

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

I really enjoyed this and will be doing it myself

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

The degreaser "Awesome", which you can get at Dollar Tree, yup, for a dollar, is amazing at removing oil/fluid stains from concrete floors. Spray, scrub, rinse or power wash off. Thanks for the video.

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

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

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

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

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

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…

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

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

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

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 🤙🏾.

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

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

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

what started as seeing how you went about cooling your garage to watching all your videos on the Z!!

Thanks brother! This helped a lot .

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.

Good choice on the Bach.

I found the static cling works great

Nice use of Satie.

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

Great video! 19:50 you registered a 40-50 degree difference in temp? Amazing! I'm going to do my doors before June 2021..

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.

Love the detail

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.

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.

Wow, nice job!

Home depot & Lowe's have the foam boards with foil on one side for 10-15 bucks that are 4 foot by 8 foot and 3/4 inch thick. I have cut them to size next to the car in the parking lot ( a little away from the crowd of cars at the front where people want the good spots) that way they can stack inside the car in what ever size your use is. I have the panels made for east side facing windows in the morning of the house, west side windows in the afternoon. Put a drawer pull handle in the middle with fender washers to keep the bolt heads from pulling through to make it easy to pop it into the window sill. Oh yeah, use the chrome looking tape around the outside edge of those panels, otherwise the little Styrofoam balls will make a mess. I have found the chrome looking tape with duct tape stuff at the 99 cent only stores and works good.

You and others might want to reconsider using foil tape. I use foil tape for wrapping heating ducts. It does not break down as does "duct" tape. It would make a cleaner and neater job on your garage. Good video! Thanks.

Good info. Thnx
