How to Insulate a Garage Door THE RIGHT WAY!

Insulating your garage door can make a big difference when it comes to a cooler garage! I this video I show you how to insulate a garage door DIY for extreme heat conditions. Simple styrofoam garage door kits don't provide a thermal radiant barrier but Polyisocyanurate foam (poly-iso) will!
Polyisocyanurate foam insulation is perfect for a garage door insulation project. It has several benefits over other foam insulations. It offers not one but two, thermal radiant barriers because it has a foil coating on both sides! Poly-iso foam is also more rigid and less messy to work with than styrofoam. This foam Is also light weight and has a nice metallic finish that cleans nicely.
For my garage door insulation project I made a cellular design with wood spacers to keep the foam away from the hot metal so that heat would not transfer by contact into the foam.
I picked up my polyiso foam at the big box store but I found the foil tape cheaper on Amazon. I put a link below.

I appreciate your unique approach to this Fred. The air gaps have to help isolate the heat quite a bit. Your attention to detail is amazing, most folks would skip the alcohol wiping but that will make the tape stick 5x to 10x longer than without that step. You are the type of guy anyone with any house pride would want to hire.

I've watched several of these vids and I like this plan the best, the double air gap will help to prevent heat transfer from on substrate to the next. Good plan. Thanks.

[@shinekraj4944]

Thanks for sharing this video. This is quite labor intensive when compared to filling up the space with 1" - 2" solid sheet. It would be great if you could follow up with a thermal scanner video just to confirm if it's worth to take this approach. Thanks again.

[@carlotta4th]

With a foil backed foam it needs an air gap or work or the foil aspect is useless and you're just putting foam in. I think this video's process is great, but maybe a bit overkill for the everyday person--I chose to just do one layer instead of the two he did (for ease and finances). But obviously two would be better than one since the air gaps let less and less heat transfer through each subsequent one. In Arizona he probably needs this.

[@MrFredsDIY]

Good luck with your project! I was contemplating this project for quite some time. I wanted to do something more than the normal thick foam kit because it’s so blessed HOT here in Las Vegas. My neighbor has the regular foam and he is happy. I just wanted more lol.

(mtn. edge) because....well i'm sure you can get a few ideas probably why and one or 2 could probably be correct. Anyway its just killing my wife and I along with are big fatty cat. i was able to get a little a/c unit but its not big enough at all to really feel a difference unless your right next to it. so iv been trying to think of how i can put up make shift walls that will help keep the cool air in a smaller area but my big issue i think is the garage door. by 8:30 -9:00 A.M. i feel that heat just radiant against the door because mine faces south and gets contact from the sun till it starts setting.... i would really like to use the stuff like you did in your video but i cant afford that. i mean i was going to see if i could collect something like really big packing foam from a maybe a fridge or what ever and wrap it in my own foil from the kitchen.. lol its like that for me right now. thank you for your time and video very easy to follow and understand. maybe if you have any ideas or know where i could salvage some scraps so we don't cook and over heat because the rate its going its not looking to good. Not to mention on top of everything i can only work on it at night because its the only time its barrable to work in there but i need to sleep at night so i can get to work in the A.M. sorry for the long message. just had to vent i guess. look forward to seeing more videos. thanks again Levi Patton

[@2-old-Forthischet]

I just used Reflectix to insulate the interior of my cargo van for my camping trips. It made a tremendous difference for hot or cold! I used the leftover material to make an insulation panel to shield my AC condensor in the patio from the summer sun. The area above the panel facing the sun was 140 degrees and the area below the panel was 95 degrees! The concrete floor of the patio where it is installed was 120 degrees!

[@alexdroban4312]

Looks really good! Thank you for sharing. I live in Arizona and am considering doing this with my garage doors. Just a couple of questions. You used wood spacers tabled to the surface. Do you worry that the heat will release the adhesive and these spacers will end up rattling loose behind the inserted foam panel? Could you have cut your panels from the width dimension, 48”, of the large foam for easier workability and less waste? Have you tested this for effectiveness? Please provide a review video months later if you can. Pros and cons and what you may have done differently. Thank you!

[@carlotta4th]

I'm on year two of my installation and haven't noticed any rattling. But I used dryer foil tape and put one on each end of the stick just to make sure it wouldn't slide around. Seems to be holding well because the foam pushes on the sticks anyway.

Here is a follow up I just finished kzbin.info/www/bejne/hn7MgJyqeNyjl80

[@chrishigh4862]

Well done. I'm in a milder climate however, the humidity makes up for it. I'd like to see some up close assembly shots of what you were doing. The right spacer being shorter confused me as the left should have been shorter as well for the top panel to sit on both evenly, correct? What have you done to combat the exposed aluminum rails? They are essentially heatsinks as well.

[@opinionsevrywhere]

Chris High, I think the left side of the door cavity is recessed. The 44" of the top panel does not go inside the recess, but sits on top at all the edges. The top and bottom is the same, not reduced width for top to sit on but to create the "box" edges. Cool project and the little foam strips around the perimeter to make the "cell" is a good effective idea. The little lattice strips should keep the back panel from contacting the doors' surface. Theory is to limit the heat transfer and 2 little contact points hopefully reduce the transfer. I edited my previous post... I watched again and the little scraps he tapes onto the back panel are the spacers to have some support for the top panel and another air gap. That right edge foam strip that goes in before he measures the panel lengths, was not a spacer (works as 1 though), but it was the edge of the "box" and was thinner because the top panel sits on top of it flush with door rails. I was a little confused too. Hope that helps.

[@justinjimenez6960]

Foil-coated polystyrene (styrofoam) board is (at least in my area) much cheaper than Polyiso, and will perform effectively just as well. As to the "double-sided reflective insulation" - reflective barriers are one-way insulating strategies. The foil facing the outside will reflect radiated heat back to the exterior. The interior-facing reflective barrier will actually be hurting your efforts in a hot climate, as any radiated heat from objects in the garage will be reflected...back into the garage. While the styrofoam can be more fragile if you scrape against it, I found its flexibility to be a bonus, wherein I did not have to cut spacers due to the design of my garage door panels that had a natural crevice for the board sections to hold their place in towards the interior side of the panels. I was able to cup/bend my board sections enough where they popped back into place once inside the metal lip of the door panels. I used no additional tape/foam/glue, and the panels have stayed perfectly in place since I did the project 5 years ago. As to the "added weight/springs" issue some have brought up - polystyrene is also much lighter than Polyiso, such that (personal opinion only) - I saw no need to upgrade my springs, nor have I noted any detrimental effects of the insulation on the door mechanics.

[@JoseMartinez-dk1pw]

As I watched the video, I did see that the interior-facing reflective barrier was facing into the inside; so, it is safe to say that it should be install facing the garage door(outside) instead?

Would have loved to see the same time of day with similar temps in the same time of year measured before and after. Another user posted that the foil should be pointed outwards, but foil is also conductive, as well as radiative. I think that its a wash between the two, but probably MORE resistant to heat leakage in climates that have colder climates as well when facing inwards.

[@MrFredsDIY]

Thanks for the insights. Having the reflective side inward helps with heating & cooling the garage space (even if only a little). Here is a follow up a year later with more data points. kzbin.info/www/bejne/hn7MgJyqeNyjl80

[@timrick2]

I admire the creativeity and the detail, but I have to side with the 2" thickness vs the 1/2". Although 2" is heavier, it is in NO WAY "heavy"!! Especially when only 3 1/2 sheets are needed for a double door. It's also a little more expensive, but the 3 1/2 sheets needed at $46 each is only about $50 more than the 7 sheets needed if using the 1/2". Additionally, rather than just the R-6.4 that you have, (R-3.2 x 2 layers), just one sheet of 2" would have given you R-13! Finally, the heat trapped in the air gap STILL has to transfer and dissapate somwhere, and that will be whichever side is cooler.

[@ramonmiquilena2423]

I also dont see where the difference between 8 sheets of 0.5" vs your estimate of 3.5 sheets of 2" (maybe is just that the cell has at least two sides and you are not making the cell design

Thanks for watching! My understanding is that both sides are foil faced but one side is reflective and the other is painted. Perhaps facing the more reflective side outward would be best.

I think that you would have a better result even though more money using thicker insulation. The overall R-value is determined by the outside air layer, the garage door, the inside air layer, the insulation and the other inside air layer. Las Vegas still has some humidity so you might see some condensation on the very inside of the insulation.

Nice work. I'm in Florida, my west facing door is 138 today. Only problem is that it's a hurricane rated door. It has EIGHT horizontal braces the whole length. Working around those will be challenging.

[@MrFredsDIY]

Wow! Good luck with your project and thanks for watching!

[@randys2358]

I'm in south Louisiana and also had to contend with a hurricane rated door. Those horizontal braces can be removed. It's fairly easy but definitely recommend a second set of hands. I removed one bar at a time, installed 1" polyiso board with 1" spacer blocks (polyiso) to achieve the air gap and to set the boards flush to the door panel flanges. I used 3M foil tape, which I found to be easier to use than the peel and stick duct foil tape. Once the panel spaces were all closed up, I'd replace the support bar and move to the next strip. Rinse and repeat. My door is south facing, so it is exposed to sun Nearly the whole day! I'm sure you can relate, that door felt like a broiler when you got within two feet of it! Using an IR thermometer, the inside of the panels read the same as the ambient temp in the garage - which this summer, has been frick'n hot! But it is still a significant improvement! Once I tackle some of the other sources of significant heat gain I should get that space under control!

[@Rudy32225]

In a FL home with those horizontal hurricane bars, I made horizontal cuts on opposite sides of the foam panel and used a Z-fold technique to fit the panels under the bar that gave a snug fit and worked well. No need to remove the bars.

[@aacar4095]

Nice video and great insulation, but if you want the super easy method, you don't have to build a box to get a fairly drastic change in insulation--you can just glue panels right to the door. Just cut 1" thick rectangular panels to your garage panel sizes, then simply put some caulk on a few of the high spots (clean the areas on the door first), slide in the panel and make sure it's resting on the bottom edge of the individual panel areas, press to make sure it has contacted the door/caulk and that's it (some use double sided tape). When measuring for the panels, make sure there's about a 1/4-1/2" overlap so the frame will slightly hold the panel if they come unglued, but mine never did. I did this in Canada north of North Dakota and even when it was like 5 degrees out, I could make the single story garage 50 degrees or more with just a little space heater. Going from a thin layer of highly conductive metal to a door with 1" of insulation makes a massive difference, even if you don't build a box and make an air gap. I just did it on a second garage recently. If you're going to use your garage a ton then I think maybe the box method is worth it, otherwise just slap up some panels ;-)

[@cskierski]

I wonder how the caulk would last in the insane heat we have? I feel like it might just cook right off. 🤣 I need to get the laser thermometer out, but I’m guessing my garage door gets to his temps or higher. The high today will be 110° F, and the garage faces west with FULL sun for several hours a day. I’m so anxious to try this!

Do you have any tips on how to adjust the garage door springs? I love this design and if I'm going to DIY this, I would like to DIY the spring adjustment. I'm just not sure on how much of an adjustment I would need. Any help is appreciated. I love the videos. Keep up the good work.

[@MrFredsDIY]

Thanks for commenting! Those torsion springs scare me so I called my garage door guy.

[@LawrenceKaneshiro]

I like the idea up to the tape. Not sure if the tape will hold up. After a year, did it?

[@MrFredsDIY]

Areas that were clean and dirt free have held up well. I have a few area that I have has to clean better and reapply. I have a follow up video for this on my channel. Thanks for watching!

[@realLunaboy1]

Awesome video! Would you do everything the same if you were concerned about a couple months of very cold weather?

[@MrFredsDIY]

If I were in a mild climate perhaps I would do a single layer to cut down on cost. Thanks for watching!

[@melrich2124]

The hindge supports are not insulated. Why did you not use spray foam to insulate? I like your approach and I intend to insulate each hindfge segment to make as complete a heat barrier as I can. Would appreciate your thought on this extra step.

[@MrFredsDIY]

Spray-foam is a good idea and the cost would be minimal. Thanks for watching!

[@derekj3601]

I can feel a draft of air coming through my garage door at the seams where the panels hinge and butt up against each other. Would covering those gaps with a bubble wrap insulation be a good idea or any possible better solutions? Yours looks great by the way.

[@MrFredsDIY]

There really shouldn’t be much of a “gap”. It could be that your door needs adjustment. Thanks for watching!

[@chuckredd9131]

Might be a little expensive, use the rubber door strips with aluminum edge. Maybe your garage door man might have some rubber stripping that goes on bottom of door. (Used/free)

Good video, interesting and thought-provoking.. I guess your door is 16 ft. mine is 18 and therefore all my sections are a bit longer than 48. thinking of piecing some of my panels by foil taping both sides to make better use of the material. Otherwise I'd only get two panels per 4x8.. My door panels might be a bit shallower too.. planning on trying to use reflectex 5/16 foam with foil on both sides, (comes in a roll) against the door and then doing what you did with 1/2-in sheet material. Any thoughts on that plan?? Thx.

[@MrFredsDIY]

Thanks for checking out the video! That sounds like a solid plan. The basic concept of my strategy was: 1, use a spacer to avoid direct contact with the metal of the door. 2, create an air void and 3, have two layers. Perhaps a spacer in the void will keep the cavity’s integrity. Good Luck with your project!

[@sumtxdude9974]

@@MrFredsDIY yeah.. I totally get your concept and what you're trying to accomplish from an insulating standpoint, but I think I really only have about 1-5/16 to work with. That is the difference between the square panel design impressions from the back side and the inside edges of my flanges.. so I don't really think I can fit half inch three times plus the space for your wood spacers.. you mentioned having about 1 3/4. Anyway, I guess I'll work it out but I like you're combination of radiant barrier, foam insulation and dead air space. It compromises but gives you protection from radiant heat in the summer as well as insulation and R-value to help hold inside temperature. Hope it's working well. Thx.

[@dcwatashi]

I just saw another video doing something similar, but he was in a cold climate and did not do the cell My garage door faces north I’m in the Pacific NW, so do I need to do this extra step? I’m just trying to insulate the garage a little more

[@tomaratari3847]

I'm wanting to do this in my garage but wondering about if condensation could/would occur and the tape holding... Currently the interior door of my garage forms ice / condensation on it during the very cold months here in Michigan. When the sun comes up over the house and hits the door, it all melts (drives me nuts!) with water even pooling on the garage floor. With the lattice gap, I'm wondering if this would still occur and then leak down and mess with the tape... Any thoughts would be appreciated! Thanks again - great video!

[@MrFredsDIY]

Thanks for watching the video. Of course here in the desert, moisture is not a problem (usually it’s dust). Polyisocyanurate with a foil backer can be used in in crawl spaces, basements and garages and one of the foils functions is as a moisture barrier. I’m not sure if the condensation would still occur between the door and foam. The foil tape is very sticky and folks use it around AC condensers where it’s fairly moist. Insulating the door might help to stabilize the temperature of the metal and seal out moisture from the garage so that it doesn’t have a chance to condense onto to door. Good luck with your project.

[@levipatton9067]

@@MrFredsDIY yeah thats smart also what about useing like a silicon to attach the spacers and not the tape ? just would take a bit longer for drying time?

How would you seal the horizontal gaps on the panels? Is there a piece of stripping you can stick just above the hangs down in front of the gap? Mine has a small draft.

Did something similar and after the first evening of working in garage added a layer of fabric to take the glare off the foil . Was maddening.

[@ambervaldivia5178]

How did this help out in the winter? Two of my rooms sit over the garage so it gets extra cold. Will this also help with that?

[@MrFredsDIY]

It does help in the winter too. Here in Las Vegas it can get down to freezing overnight in the winter. I have a small heater I use in the garage and the insulated door helps. Thanks for watching!

[@stem_saving1644]

This is definitely the way to keep heat out with radiant barrier. Air gaps are the key that people fail to understand. In cold or mixed climates, it won't be as efficient at stopping thermal heat transfer. But your in a mostly hot climate. I chose 1.5" pink insulation for mine since I have both extremes of heat and cold. Definitely nice build. Any results on temp drops for before and after?

[@jeffbguarino]

From what I understand the best air gap is about 1/2 inch. Any more and you have circulation and defeats the gap function. You are best to put more layers of insulation which have the microcells already in the material. The weight of the insulation is not important. You just adjust your garage spring so that the door is actually weightless. Also the hot or cold climate does not matter. In a cold climate the hot area is inside and in a hot climate the cold area is on the inside assuming you have A/C. My wall of my house have R 20 insulation and on the outside is R 10 Blue SM. If made an airgap in the middle of my wall , it would just lower the overall insulation of my house and do no good at all. The insulation value of a 1/2 inch airgap is about R = 1 while the 1/2 inch Polyisocyanurate is probably about R!0, so 10 times better than an air gap. Also if you use airgaps , in places that aren't walls so you have space for air gaps, to keep them to 1/2 inch or they are useless. The air inside quickly sets up a convection current and transmits the heat or cold perfectly.

Wow, I have never seen such a thorough garage door insulation process. We live in New England, and it gets pretty cold up here. What do you think the R value is for a cell insulation solution like this? I wonder if it would be sufficient for freezing temperatures that sometimes dip below 0.

[@ThePetessf]

The air gap really increases the R value, if you glue all the components together airtight. It will work on New England for sure.

This is timely, my finding this video. I live in Austin, TX and it's been really hot this summer. I think insulating the garage door would help a bit plus blowing some insulation into the attic above the garage. *QUESTION:* The door doesn't seal well on the sides and top. Any ideas to improve that? Weather stripping at the top should be possible but, if I put some on the sides, the door might drag it off after awhile. Thanks.

[@MrFredsDIY]

If you look at 2:24 you can see that I have garage door seal installed along the top and sides that doesn’t interfere with the operation of the door. Thanks for checking out the videos!

[@RobertShaverOfAustin]

@@MrFredsDIY Thanks for the quick response. I looked at the prices of the 4x8 sheets half inch thick and they were $37 each. The 1.5 inch thick boards were only $18 each. Must be a big demand for the 0.5 inch stuff. I think I might use the 1.5 inch for the price savings even though it will likely be less efficient. What do you think?

any suggestions on how do this install when your garage door does not have a frame for the cell to lie on? The inside of my garage door just has the hinges, but no horizontal or vertical frame for each rectangle. i could just tape the first spacers directly onto the door, but am worried that the tape wont hold all the weight from the entire cell over time?

I like this idea…I don’t like the tape showing because I’m a little OCD. But I do need some horizontal bars to reinforce my door from winds .. (Oklahoma) ..the bars could hold the foam in place…I need to think about this. Thanks for the idea for sure! What was the post instal temp? 😂
