The Easiest & Most Effective DIY Garage Door Insulation

[@georgehernandez4195]

I did this to my garage yesterday with 1” board. My wife asked me what I was doing. I told her and a day later ur video popped up on my KZbin feed. When I was done I opened the door and could hear the opener struggling. I saw ur video a day later and made me look up the specs on the 1” board. To my surprise they are 5 lbs per board. I used just under four boards. That’s just under 20 lbs added to the door. I took the door off the opener and sure enough it was harder to open by hand. I added three 1/4 turns to my spring and that seems to make up for the extra added weight. The opener sounds back to normal. I put a new spring a few years ago and up sized it from original. Thanks for the tips 👍🏽

[@matthewhorwat7540]

You should have enough tension in the springs so that if you do the manual release so the door is disconnected from the door opener, the door shouldn't close by itself, and should require virtually no effort to lift it.

[@BOHICA_]

I see garage door installers weigh the garage door with a scale.set in the middle with the door disconneccted from the opener. You are looking for less than 10 lbs.

[@ROCKINROBIN7791]

i did this 2 years ago with same board. but i added a sheet of bubble insulation first, then the board and then another sheet of bubble insulation. and finally i added foil tape to hold the bubble insulation and board inplace. came out really well. way less hot in the summer and less cold in winter. one thing to remember is a well insulated garage door by itself is only part of the solution. u have to make sure the space above and around the garage is well insulated or u wont get the desired temp. u want.

[@ROCKINROBIN7791]

@@christophermackin147a roll of bubble insulation you can get from lowes. just an added barrier. I also learned that you can install a temperature controled ceiling fan vent in the attic ( not the bathroom kind) or on the side of the garage wall. both options will pull hot air from the garage along with small inlet vents in the garage door to let outside air circulate through the garage. that will help keep the garage cool. next on my to do list.

[@Wankidy]

How many foam sheets did you use for your project

[@ROCKINROBIN7791]

@@Wankidy three 4'×8' 1inch thick foam boards.

[@brenthood3399]

You can buy a foam insulation kit from some local Garage door companies. They will be cut to the right height 21" for the top and bottom and 16" for intermediate sections. They will be 8'ft. long so you cut them about in half depending on the width between the vertical styles where the hinge's mount. they often have a thin white PVC pebble tec finish backing skin so the whole door is white inside. This is easy to clean when you get dusty spiderwebs on the back of the door. They are not cheap because the Garage door company wants to make a healthy profit as it is a specialty item. They are installed the same way the insulation was installed in this video. They are a snug fit and it is a bit of a wrestling match to get the panels in place. I could insulate a whole door in about 2 hours but I have a lot of experience. If I were to do this I would compare the price of the kit versus the cost of enough sheets of Owens -Corning insulation to complete the job at your local Home Depot. If you Garage gets Western sun in the afternoon this will keep the garage much cooler. However, if you pull your car into an insulated Garage after your commute home it will also keep the heat from your hot engine in the garage. The insulation will add weight to your garage doors spring(s). They may need to be adjusted to get the door to open smoothly. Call a pro to adjust the spring. It will be much cheaper than a trip to the Emergerncy Room if you try to do it with out the proper tools and knowledge and some thing slips. If you try and get hurt you will still have to call a pro to get it done. Trust me. Springs can kill. Let a pro take the risk.

[@Just_A_Name14]

[@johnrogers1423]

I filled the whole panel space by cutting the 40 mm thick polystyrene sheets to the correct size but in two halves. The top and bottom halves could then be angled in at the top and bottom and pushed in together in the middle creating a very tight fit. I cut two of the rows approximately 20% and 80% of the panel size as the door's reinforcing rails would then cover the joins. The sheets have been in place for 5 years now and none have popped out. I also glued wall wrap (foil) behind the foam. I also corrected my mistake of not ordering the west facing door in white by painting it white to reflect the afternoon summer sun.

[@shubinternet]

I appreciate you letting us see your mistake and how you fixed it. Thanks!

[@127001er]

Definitely need to seal around the edges of the door. My garage door is 16’ x 7’, and it really flexes inward in a strong wind, which lets rain and snow to get inside past the seals. Some things that have helped with that problem are: brush seals for outside surrounding the door, the ‘Green Hinge System’, a double-bulb rubber bottom seal, and a threshold seal. These four things have made a significant impact in reducing water and snow intrusion. Thanks for the video.

[@smody121]

Be careful doing this, make sure you leave a little gap and to not seal the door air tight or you might start getting mold if you don't already have temp control.

[@LRN2DIY]

Great points. I noticed while I was shooting some thumbnail pics that just standing next to the door I felt a breeze and, after feeling around, it was coming from the gap at the top of door. I haven't yet installed the seals (I thing I'm going to seal the living daylights out of this thing) so that makes sense but it's crazy how well that cold (or hot) air finds a way in. I recently finished installing rock wool through the garage and will be installing a mini split soon so it should be very comfy in there by the time I'm done.

[@127001er]

@@smody121 I agree,but there’s still some air intrusion even with those things installed. For my needs, they have really helped to reduce the wind driven rain and snow from blowing into the garage. My cement slab can form some serious condensation under the right conditions, which is why I installed a cheap, small ceiling fan. And my garage walls aren’t insulated yet. Maybe some day.

[@ericsaresky6246]

XPS, including the new NGX, polystyrene foam board is highly combustible and must be covered with a protective or thermal barrier to separate it from a interior living space by code in most areas. Since a garage door is exterior and not to a adjoining living area, it would probably pass code. However, not mentioning that it’s highly combustible to your viewers is a concern. Someone adding a XPS to their garage door that may do work such as welding or grinding, will find out just how combustible it is.

[@MoneyManHolmes]

Is there anything that would perform similarly and not be a potential fire hazard?

[@chrish42000]

Id watch a video of someone testing the flammability of different foam boards, and painted with fire retardant paint.

[@finchhawthorne1302]

A super important consideration! Especially because a common objective with DIY garage insulation is to use that space as a living space or or as a workshop.

[@caitiekay3306]

This sounds important and should be pinned

[@5467nick]

@@MoneyManHolmes Vacuum insulated panels and aerogel can be non-flammable and have very high insulation per inch, but are relatively expensive compared to other insulation. Some foams can include flame-retardant chemicals so they can't sustain a flame and won't spread fire, though they will still be damaged by heat and may give off nasty fumes while hot. Cement foam might also be able to qualify in some formulations, though it's not as common as other options and might be too brittle for something like a garage door.

[@scottrsmith2389]

My garage door just died. It was 24 years old and had many added braces to repair fatigued metal and such. But it finally gave up the ghost, jumped the track, and almost fell on the car. it was time. Guess what? You can buy new doors that are heavily insulated with R10 or even higher. Metal on both sides, insulation in the middle. And it wasn't that much of a percentage more money than the cheaper non-insulated one. 15% to 20% more or so. More? Yes. But not double the cost or anything. Now it is well insulated, and also far stronger and rigid. Now, it's very much like an insulated steel front door. Big improvement. So, if you are at the point of getting a new door anyway, look at higher end double-wall insulated ones.

[@kweejee]

Thanks for the info. I'm on year six of "probably should replace this."

[@ScytheNoire]

Watching you put the wrong size panels on the top and bottom was driving me crazy. Glad to see you went and fixed it. Best way is to probably make a grid ahead of time and measure each panels, just in case the top, bottom, or sides are different.

[@Openroadoutfitters]

Thanks for this video. I bought six 4 x 8 sheets and did both the double and single garage doors, with hurricane braces, in about 4 hours. One of the easier home DIY projects I've done. I have yet to seal them in place with spray foam but the individual boards are staying put, no problem.

[@steve_hall]

Please be aware that rigid foam insulation is highly, highly flammable, and by code is not allowed to be exposed on interior finishes. And garages tend to be a location with open flame and where most house fires start. Better a proper three-layer insulated garage door with metal panels on both inside and outside faces to meet requirements in many jurisdictions and safe practice.

[@jacojaco8436]

Hi. Do you have the name of the panels you’re talking about??? And what R value do they have?? Thanks.

[@steve_hall]

@@jacojaco8436 I'm unaware of any retrofit solutions because of the challenge fitting insulation and protection, combined with the added weight. As Nils illustrates, the insulation alone is challenging, but non-flammable protection adds weight. I've seen people try this with fiberglass batt (non flammable and light weight) but it's loose, can get caught in the hardware, tough to hold in place, and has too much air leakage and lower R than rigid to be an effective insulator, even with foil facing. Most manufactures I know use options from the factory, for example, a 1000 uninsulated, 2000 insulated interior-protected with polystyrene (barely non-flammable I suppose), and 3000 insulated interior-protected with steel.

[@allenfranklin225]

Any alternate suggestions on insulation besides purchasing a new door?

[@seant4884]

Per Owens Corning on Home Depot’s website for this material, “Foamular is combustible and requires a protective barrier or thermal barrier as specified in your Local Buidling Code.”

[@manyakus8919]

Good job, definitely will reduce heat transfer..depending on where you live, your code might require you to cover the panel (fire hazard).

[@spacecoastkid5033]

In live in Florida and it's required to have hurricane bars horizontally across the door. Mine has 5 huge bars which I would need to remove in order to install foam panels.

[@Mattthewanderer]

Nice. This would be a worthwhile upgrade for my simple garage door even without the full seals. My primary trouble is extreme heat radiating through the door on summer afternoons and this would work nicely to lessen the heat buildup in my garage.

[@abnereng5161]

The last insulation install on our garage door made the door very heavy. The spring needed adjustment. Just went with a lighter insulation. The heavy foam insulation caused the garage door to not stay open.

[@joshuabourdon8110]

Sorry if this is a duplicate comment. Installation of this material as suggested is unsafe. Per the manufacturer, "Owens Corning Foamular products are combustible and must be covered by a 15-minute thermal barrier such as 1/2" drywall. We do not recommend using Foamular to insulate a garage door. There are better choices such as the Owens Corning Garage Door Insulation Kit. Thank you for your inquiry!"

Ok that works and looks good but you made way more work then you needed to do.

Then you put one edge in and give it a little bend and pop the other edge in. It'll fit tight, no spray foam needed and the lip on the garage door panel holds the foam in.

Pro-tip from an avid DIY’er that’s also in his 60’s. In order to do it thoroughly right?, you have to take the screws out of the hinges allowing you to get a bigger piece nestled or nested into place taking up the entire panel void-space. No need for messy spray-foam crap.

[@JJP1960]

So you're saying you can cut to 17.25" and they would fit perfectly? I would think there would be more waste? But to get a perfect fit WITHOUT the foam spray then it would be worth it.

@@JJP1960 it’s arduous to take out the hinge screws in order to do each panel - But I’ve done my own garage door & I did my daughters last year in the middle of July. Slow & steady, measure twice cut once & man-handle each foam panel into place. It’s not fun, But it’s nice, neat & not so messy without having to use a $20 can of spray foam.

Then he had 1.5" foam board left, the type with the foil on one side. We filled the panels with that foil facing in. So there is foil on the outer side of the foam and the inner. We used expanding foam to be sure all the recesses were filled. We also used foil tape to cover the gaps. Most stuff he had left over from doing the house, except enough foam, one more foam board, and he had a roll and a half of the foil tape left from redoing the HVAC and I got some of the tape from my bro who has done HVAC for 40+ years...needed a bit more to finish it. The door no longer gets hot and it faces south and in the winter you put your hand on the outside of the door and it is cold, there is no heat escaping. The foil board inside cleans easily and it reflects light, we noticed that right away. He had a broken door spring already and he replaced it with a heavy duty one.

I've tried a lot of improvised tools when I needed it and some work but I've also been hurt by the ones that didn't.

[@LRN2DIY]

I've already done the spring replacement. I bought winding bars and went through the entire process of weighing the door (with insulation) and getting the properly rated new springs for the new door weight, then VERY carefully removing the old and putting in the new. It was a pretty reasonable experience but half the video (that is coming out) is about safety. I know it can be a dangerous process.

Had you cut the height of the panels from the inside of the top and bottom C-channels, and then cut all the panels in half length-wise, you could have avoided the spray foam altogether by first inserting the bottom half of the panel and then inserting the top half of the panel.

[@abbytomkiewicz2232]

Thanks! I am going to do that! What type of spray foam did you use?

[@TheMadHatter10-6]

How many boards did you use there not including the mistake?

[@hankwest5662]

I used single side reflective, on thr interior side it is white. However during install i stuck it to the support struts, creating an air pocket between the insualtion and the garage door.. I notice when you did the test st the start, you sruck the reflective insulation directly to the garage door. All the DIYers ive followed have shown its far more effective creatinf an air pocket in the door, bexause obviously air doesnt transmit temperature as well - similar to the way a dry suit works much better for divers.

[@drdrako98]

Not sure if you check comments on old videos, but I’m curious how it holds up to static electricity and shop dust (like sawdust)

[@greatpix]

I wonder if you could use some thick rope to fill in the gaps instead of the foam and if it would be effective insulation too?

[@alexandermaciag377]

Hello. Did you also have to make adjustments in spring tension on your garage door since there is an addition to the weight of the garage door lift and retract?

[@justthoughts8254]

love it! thanks for this content

[@QuinaeShanice]

Thanks for sharing. Now would this be great for a garage with no venting as well??

[@thefeds2579]

You earned a like for the spray foam removal. I honestly would have left it as good enough instead of digging it out.

[@30fold]

This may be fine for temperate climates, but not in Arizona when the sun shines on your door. The amount of radiant heat transferred by all that exposed metal not covered by the foam board (the joints and sides) is still enormous. It's just one giant heat sync. I'm wondering if there's some type of coating that can be applied to the entire inside surface.

[@twister434]

Paint the outside of your doors with the most reflective (mirror type) paint available plus that will really piss your neighbors off.

[@BoomaOhDet]

Think the added weight would overload a Chamberlain belt drive garage door opener?

[@joef5014]

Did you stack 1” and 1/2” sheets? Can’t find 1.5” thickness anywhere. Great video!!

[@zenginellc]

In case this helps anyone, the big box stores near me don't carry the same things: Lowes: $46.48 - FOAMULAR F-150 | 1.5" Thick | R-7.5 Home Depot: $21.58 - FOAMULAR F-150 | 1" Thick | R-5 $43.00 - FOAMULAR F-150 | 2" Thick | R-10

[@user-LarryG1261]

Thank you for this. What about roll up garage doors?

[@SyddlesFuzz]

Sweet! Thank you for this~ Going to do this in my home.

[@SyddlesFuzz]

Do you think the reflective foil, on the other side of the insulation, would be helpful?

[@LRN2DIY]

This kind of insulation doesn’t have the reflective foil. It’s a denser material with a higher R-Value than the white and silver stuff.

[@SyddlesFuzz]

@@LRN2DIY The question was about adding some

[@eotceotc]

@@LRN2DIY What I wanted to know was not the garage door heat difference but the overall garage temperature. Do you recall how much the entire garage temperature went down by?

[@granitetek]

I used the foamular ngx to insulate my garage door after watching your video approx 2 months ago. I then used Big Gap filler around the edges as noted. Today I am noticing in the upper and lower corners of each panel it looks like the board is having a chemical reaction of some sort and is breaking down. Look almost like someone took a lighter to it. burnt styrofoam look. Any ideas?

[@Rio2002]

so i too want to cool down my garage went to a local auction company and picked up 20 panles of 2 in foam board for $125 then started researching on how to glue or tape them in. saw you video at number one and i watched it, then watched the previous one. so then i checked the temps in my garage and my door was about 105* and walls were about 110. then i checked my roof and it was 135*. i saw you house has a room above it so you dont have to worry about heat from the top. would using 2" foam for the roof be a good idea also?

[@pjseiber2774]

When I purchased my garage doors I got them already insulated. Would it be worth the time and expense of changing out the insulation. Mine also leak lots of air at the joints between the panels.

[@marcelogomes2870]

Nice video. I'd just like to mention that only the heat transfers in or out. Cold doesn't.

[@ishangaur9667]

@LRN2DIY - My main requirement is to insulate garage for cold weather and use it as my Gym .I am in NW Portland Oregon where temperatures avg 40 in peak winters . So far I tried doing only reflective material to insulate the garage but it did not make any difference I would say at all.. how do I solve this problem to keep cold outside of the garage is it even possible?

[@tiamogonzalez3641]

I like you, man. Great video

[@davidcronhelm4804]

How you fire rate foam

[@rpdx3]

Measure once, cut twice. That’s my motto! 😅

[@kjisnot]

Does it really make that much difference to do the foam to fill in small gaps? In my case I was interested in reducing radiant heat from the metal panels in the afternoon summer sun. It did help a lot. However there is always air and not much insulation going on around the door edges where there is typically a thin vinyl weather flap. Heat and cold will always be leaking around there.

[@OnTVaustralia]

How much heat radiates through the internally exposed sheet metal?
