Which Garage Door Insulation Works Best?

[@willusher3297]

Thanks for all the effort put into this. A couple tips to improve accuracy: 1 - The laser dot is marking the center of a circle and the temp is averaged within the circle. The diameter of the circle is dependent on the distance and the angle set by the manufacturer. Check the manual for this info. 2 - the paper wasn't making good contact with the insulation, so there was very little conductive heat transfer. 3 - paint a black matte section directly on the insulation and read the temp off of that at a close range for the best accuracy (verify w/ a thermocouple taped to the service, or similar).

[@brendancurtin679]

Also the outside temperatures were pretty varied. So, Idk if percent reduction in temperature is all that useful when comparing one panel with a 220 degree outside temp to another with a 180 degree outside temp.

[@Qwerty-y9h]

Agree about #3, there's no control for the different emissivity of the materials. Not sure how accurate this analysis ended up being.

[@jmackinjersey1]

Exactly, that is one reason he was getting the different temps on the outside, especially between the two temp guns. 1 foot difference in distance makes a huge difference in temp reading.

[@cryptonymsslc]

[@BriBo24x7]

By the way, I've also installed a mini split AC in my garage. I used the 24,000 BTU unit from Senville for our 3-car garage, which is much cheaper than most units at $1250 US dollars at the time I purchased in Feb of 2023. A guy in my neighborhood installed one before me and he recommended it based on their price, and phone support. He called all of the main companies and Senville's support was the best. I can attest to the support because I ran into an issue with the AC drain pan connector leaking, and they sent me a whole new inside unit. I was initially considering the 18,000 BTU unit, but I'm glad I went bigger. I left unit going nonstop during the hot months and set to 76 degree, it felt really cool in there. It's so nice! One thing I'll warn you of is be thinking about what you'll do with the condensation. These units can fill a 5 gallon bucket in a day, and the ground will be saturated where the drain line drips. I ran PVC to a flowerbed about 10 feet away and the plants in that area love the extra water.

Great video comparison! Having a 100° garage was very unpleasant! After 2 years with my insulation I have to say that my garage is much more people friendly now. Thanks for the shout out!

[@jimh4375]

[@Favs3916]

IR thermometers measurement is dependant upon the emissivity of the material. If you want accurate results then stick some black pvc tape on and ensure it completely covers the field of view ( touch it against the material or cover a much larger area than you're measuring.) This can completely change the readings.

[@charlie-jay]

Came here for this comment, and agree totally.

[@slamdvw]

that's why he was using the paper...

[@Traqr]

Also get closer. The laser dot is just for aiming - these IR thermometers read from a cone, 10:1 for the Klein single-laser unit. That means reading from 8' is measuring a bigger spot than the paper.

[@Traqr]

​@@slamdvw... Also, looking through the IR camera from 8:15 is clear that the paper is only warm in about the middle third, where the tape is holding it near the insulation. The "wings" that curve away from the wall are almost room temperature. Interestingly, you can also see the "heat reflection" of the foil-based insulators.

[@pit9820]

What are you talking about)))) look's like this guy took IR thermometer for the first time in his life🤣🤣🤣

[@kstack34]

After watching this i was about to go get some OC Foamular boards for my garage but luckily did some quick research. Owens Corning warns against using their boards in this manner because they are combustible and require a thermal barrier. I hope you put up a disclaimer.

[@Prepheckt]

Did you find a replacement?

[@alexnelson9505]

The double reflective insulation is a radiant barrier and needs an air gap. If you install it on the inside ridges of the door with polyseamseal, it will seal the segments of door and have the highest R value with the least amount of weight.

[@Bama1963]

I just used the Owens Corning fiberglass insulation on my 2 car garage 8 panel door and I only had to pay $142 from Lowe’s for the 2 kits. Not only is it warmer in my garage but the door is remarkably quieter when it’s operating.

[@charlieman007]

I still haven't done the insulation because I was wondering what method to use from the different videos on KZbin but you did the work for me, now I know which one I'll use. Just EXCELLENT !!! Great video, Thank you !

[@rrome6178]

I really appreciate thorough comparison of the techniques, their effectiveness and cost!

[@adambrenner]

Great video. However, please note that Owens Corning Foamular products are combustible and must be covered by a 15-minute thermal barrier I would not recommend using Foamular to insulate a garage door.

[@mattpengelly]

This was a really informative and well done video. I will definitely use the information I learned here. I did want to make one suggestion: a percentage temperature drop isn't really an accurate conclusion from the results. The reason is that our temperature scales' zero points aren't really zero temperature. They're just arbitrary points on the spectrum we assigned to be 0. 0 Celsius is more useful than 0 Fahrenheit, obviously, but neither truly represents zero temperature. Point being, 100 degrees is not twice as hot as 50 degrees and a drop from 100 to 50 wouldn't really represent a 50% drop. The only way percentages would work would be if you were using the Kelvin scale, whose 0 point truly is zero heat at all. But since none of us think in that scale, everything else would be meaningless to us. I think using actual temperature drop would be a better measurement. I'm sure you converted to percentage because your outside high temps weren't all the same and you were trying to account for that, which makes sense, but I think the problems with percentages just compound the discrepancy.

[@PedroCoelho98]

With those IR thermometers the further away you read, the more area you are getting the measure from... the laser dot seems to be the only point you are measuring but read the manual and it will tell you the area being read with distance...

[@LRN2DIY]

Great info. I'll have to experiment with that to see what that might change.

[@Alero2k4]

A few years ago I did an install using the owens corning kit and then went around the edges with foil tape. It was a literal night and day difference in the garage temps. I did have to have a local company come out and replace my springs due to the added weight on a double door, but it was completely worth it! I also want to add, you should have your door springs adjusted regularly, it’s cheap to have them come out and they do lose tension over time and tend to stabilize after about 2 years of daily use. It’s not really a one and done thing.

[@robertgarrett7007]

I agree completely. I adjust my door springs myself after watching my installer and watching several KZbin videos. ( I’ve been involved in home construction for years).

[@Keifsanderson]

Great tip on the rebalancing the garage door spring. I hadn't thought of that.

[@brunodemelo4997]

The thin reflective sheet could be mounted with an air gap. So they could have been mounted to the door frame rather than the door panels.

[@evahsia]

This would add a R value of about 1, excluding the thermal conductivity of any material installed between the door and the sheet to keep the air in place. Per my calculations, that would bring the option up to an R value of about 3.8.

[@pazu8728]

I think another yt video mention that without the air gap the double reflective insulation became heat conductor and be less effective. Any reflective material is for repelling radiant heat transfer not for stopping conduction heat.

[@IL_Bgentyl]

How I installed mine. Made a solid difference but not sure exact numbers

[@Shauny_D]

what about to keep heat in during the winter?

[@jkelley14701]

As I understand it, the double reflective stuff is supposed to have an air gap. It's in the instructions. Using the reflective stuff as the final layer in Fred's method would likely increase the efficiency.

[@ecoomber]

Awesome video as always! I live in London in a 1960s era apartment block with no insulation (it's crazy, I know). I'm on the 10th floor and have a wall of windows that are 80s-90s era but so drafty in the winter wind. I've done all the rubber strips and plastic sheeting stuff, but what really works is putting in foam panels in the windows! Yes it blocks the view, but when I wake up for work in winter it's dark outside and when I get home from work it's dark already, so it's no big deal. The foam is pretty easy to work with for beginners and is renter friendly.

[@MrNside]

Reflective face insulation is by far most effective with an air gap. It usually says so on the insulation board itself. It's manufactured to be used as sub-siding with either vinyl siding or brick on the outside, creating that inherent gap. The DIY Fred solution is just following recommendations from the insulation maker, and then doubling it up because why not?

[@cadthunkin]

I would think the dominant factors are flammability, durability in presence of moisture, and weight. The pink foam flammability is scary to me, I won't be doing that though it seems like best option otherwise. The eps (not xps extruded) styrofoam can absorb water I thought. Sealing it like Fred's method seems like asking for trouble. But maybe the foil faced foam options deal with water so those then stand out as best. That service call to adjust spring will cost more than the entire installation so there's that...

[@BiggMo]

13:57 the Springs are considered a wear product that occasionally will require replacement. Tighter springs result in shorter life, so the cost of the added insulation could escalate

[@asusreviews]

True, and probably best to oversize springs when replacement time comes.

[@shubinternet]

You could combine the Owen's Corning NGX with the lightweight double reflective insulation that is taped to the frame, and give you an air gap between them. That might be the best combination.

[@LRN2DIY]

That would be a great one to try for sure!

[@DougSims]

I did this as well for my garage door. Made it bearable in the summer with a west facing garage door in the south.

[@elysiarodriguez6599]

do you mean the double reflective bit goes first in the slot and then the NGX?

[@CeasersWorld]

I actually just did this! Double reflective insulation before putting on the NGX and it’s made a huge difference. So much of the heat doesn’t enter the garage now 👍🏽

[@decibellx2194]

There is a lot of these vids out there and it's a great project for the DIY person. one thing that is often left out is the insulation adds extra weight to the door. not a ton but still extra. I learned this the hard way. That extra weight also wears on your springs and can shorten their life.

[@LTVoyager]

Having the lower panels much hotter than the upper panels completely invalidates your test. The higher temperature on the outside will greatly increase the amount of heat radiated outward and thus a good part of your “greater” temperature differential inside to outside has nothing to do with the insulation on the inside, but is due to a faulty test. You need to test again ensuring that you have the exact same temperature on the outside of each panel.

[@ColonelSandersLite]

Yep. This exactly. TBH, I also question the overall utility of this. I'm sure it helps some but with all those gaps in a garage door, the thing's gonna leak heat like a sieve no matter what you do.

[@jaredanderson2009]

The lower panels are hotter because the insulation, all the heat that would be leaking through the door is being isolated on the outside since the insulation isnt letting it through. So you could actually use these outside panel temps to show which insulation is better as well

[@rm5282]

Remember, the lower panels will probably be hotter due to proximity to the concrete landing in front of the garage. Depending on how hot it is outside, the lower panels may be exposed to more heat.

[@stargazer7644]

I would have just kept ambient temp outside and heated or cooled inside the garage and monitored the face temps of the panels. You need to adhere the same material to the inside, and make sure the thermometer is only measuring that material for emissivity reasons. The IR thermometer measures a circle much bigger than the laser dot.

[@stargazer7644]

@@ColonelSandersLite It makes a huge difference. Just make sure you don't have air gaps around the door.

[@davidwostrel]

Why is everyone so scared of these "torsion" garage door springs they are completely safe to DIY. They are not "tension" springs with hundreds or thousands of pounds of pressure on them. I really feel like there is this lie that people that overcharge to replace these springs "professionally" are perpetuating all over the place that they are super dangerous. Buy the $12 proper tools to adjust them and save $500 every time they fail, and fail they will because they don't hold up to as much use as we put them through now. But if you do add insulation to the door you should not just "turn up your springs" you should replace them with heavier springs so they are not straining more against the load and will fail faster. Torsion garage door springs are DIY friendly! Tell your friends!

[@TomahawkDIY]

Very interesting! Thanks for the summary at the end - I love that the top two in performance didn't add too much weight, were economical, and one is pretty quick and easy to install. Could be interesting to add in the insulation installed by a garage door company to the test.

[@LRN2DIY]

Hey Mike, for sure. There are a dozen or more other solutions that would be fun to try but at least, like you mentioned, there are some efficient and inexpensive options to start with.

[@petem6503]

The least effective at 43% is actually the best value, and since the max performer is 56%, the performance between the two isn't quite as much as you might think. If it was me, I'd simply take all the bubble wrap I get from Amazon and See's and get to work taping them up. In most cases, the bottom line isn't heat flow, but the cost to heat or cool the heat flow. "Cost" includes mechanical heating and cooling, but also includes the insulation treatment. It actually takes rather little improvement of a bare metal panel to make a big difference in performance. The first 4 of "R" are the most impactful.

[@aaron2a540]

It's worth noting that is only true on the day of purchase but as time goes on your heating or ac cost will likely trump that initial cost difference.

[@stargazer7644]

You cannot take percentages of degree measurements and compare them. It's meaningless. What's 10% of zero degrees? You have to convert to Kelvin first.

[@SilverSparrow5]

Don’t pay attention to my username as I’ve had this account for like 13 years. I work as a garage door technician. You’re never supposed to add insulation to an uninsulated door without changing the springs. The springs are designed by weight so adding to it after will screw that up. So if you’re planning on adding DIY insulation, also plan on paying $300+ for new springs. Adding more winds to the current springs will just reduce the life cycle and cause them to break prematurely. Garage doors are a lot more complicated than people realize.

[@lazygardens]

I insulated our garage door with styrofoam panels, and it didn't make much difference in the garage temperature, BUT it definitely decreased the icy draft flowing down the door in winter. Comfort level is much higher. Door faces north, single garage is in walk-out (and drive-out) basement, almost 100% underground with living spaces above and on one side. Keeping cold out is more important then keeping heat out.

[@rcguymike]

Most of the heat leak will come through the metal of the garage door itself. You should try a kit that attached to the inside of the metal. I was able to cut the kit so that when closed it butts up pretty tightly together and you take the hinges off 1 or 2 at a time and run the foam and radiant barrier underneath. The screws will still conduct but it also makes the door significantly quieter in operation as well

[@marklefler4007]

Minor suggestions: most paint reflect some Infrared, which is how the thermal temperature measuring devices works. So you might have been getting a reflection of the heat source when making the outside measurements. Best to turn off the outside heat source and move them out of the reflection line, or just use a direct contact thermometer. None of this should change the relative performance between the samples though. It just might have exaggerated the temp difference.

[@bobbg9041]

On the solid owens corning closed cell the 1" and add an air gap. Then the reflective over that also taping the sides. The reflective works better with an airgap you you put it right on the metal it lowers the effects, thats why the bottom left one works the best. As far as getting a 2" thick sheet in, no problem, cut it into 2x2 squars Pluse the 6" the side rails are 3" each side added. Take a circlur saw and cut a groove down the center you slide one side in add gap filler then slide the other side infill the gap with spray foam and run foil tape over it. One big draw back with a foam insulation if it burns it gives off very toxic gases, by code it cant be exposed. You have to have a 2 hour firewall over it.

Great test. I like the results you came up with. Remember if you add weight it might not just be adding tension to existing springs but a completely new set of springs.

Cool experiment but to be honest I would like to see a more controled experiment done inside so the varibles such as lighting and heat can actually be controled.

[@jdjohnson]

As a garage door guy I recommend the bubble insulation. Any of the other choices not just required adding tension but to do it properly the spring needs to get changed to match the new doors weight. That repair is usually more than the cost of insulation. If you want to go with the thicker stuff I recommend doing it when you're already planning on changing out the springs. Springs are only rated for 10,000 cycles and depending on how you use your door those 10,000 can add up pretty quickly.

[@2mustange]

From what i have researched, gauge, length, quarter turn all determine what can be lifted and the gauge usually determines life cycle if done correctly. But in most calculators they give a range. This method is adding 10lbs so likely can still be within spec

[@MrFriday83]

​@@2mustange Probably, but not certain. You'll probably get away with not replacing the spring.... But, the other thing is how old is it? If its pretty old might as well replace it,.. Its easy to get sucked down a rabbit hole by adding the weight. just be prepared to. I think Johnson's advice is spot on. Most doors are out of balance, now add 10 pounds? Its going to show it even more. So, if you're planning to add weight, you should be prepared for someone to come out and rebalance it. This is NOT a DIY project they are stupid dangerous.

[@SilverSparrow5]

Well they do make high life cycle springs that are made to last past 10k

[@SilverSparrow5]

@@2mustangeit depends on the door length and height really. Not all doors will just be adding 10lbs. You’re not supposed to add insulation to an uninsulated door after springs have already been installed for uninsulated weight. Just asking for one to break then you’ll be out of pocket $300-400 for a new set. Some companies charge $400+ in some states. Garage doors are a lot more complicated than people realize.

[@jdjohnson]

@@2mustange I have software that gives my technicians exact numbers 🤷 and really a lot more goes into it than that. The doors weight, drum size and radius all go into engineering the proper spring size. Does it have high lift or is it pitched at a angle, that all changes the IPPT and in turn changes either the gauge wire and or length. If you want more cycles you will have a longer spring but that will also change the gauge needed to match the IPPT. If you run out of room and go too long to fit you can play with the diameter and make it larger or smaller to get different results or even go with a quad spring setup.

I agree with those who suggest the percentage should be based on the absolute scale. But it doesn't matter for heat flow, which is only dependent on the difference in temperature. Q=kΔT. I estimated the actual R values, taking into account the R value of the door itself (Δ20°F). I get the following, normalized to R5 Formular. (Estimate is +/- 10%.) Door Δ20°F - R1.7 Silver reflector Δ55°F - R2.8 Gap filler foam Δ57°F - R2.9 R8 FG Δ61°F - R3.1 2" Rigid Foam Δ77°F - R4.0 R5 Formular Δ97°F - R5.0 DIY Fred Δ100°F - R5.2 I think the most interesting question is why the R8 fiberglass performed so poorly. Possibly because it was pushed in collapsing the depth.

Great clip, thx for the data. I note others warning of OC requiring a thermal barrier but I see it advertised as garage door insulation. Any additional knowledge since you made this video? I was wondering about a reflectix underneath as well as tape around the edges instead of spray. Thoughts?

[@AronGreen]

One I've seen (and wanted to try myself) is the double reflective and 1" formular. I forget which way is best, the reflective first or reflective second.. but either way, that's what I had seen and wanted to try myself.

[@anthonyarrigo2202]

One of your best. Thanks for the information.

[@LRN2DIY]

Thanks so much!

[@gregmize01]

props on your audio volume!

[@54ameneses]

Great and useful video! Considering the cost of a tech to tweak the springs, what weight could you add without adjusting the springs?

[@fennkevin]

Tom's Key rocks! Turns out we have a mutual friend :) Mike is my brother-in-law. Great video. I purchased a roll of the double reflective insulation but haven't installed it yet. Bought before watching your video. Looks like it will definitely make a difference for cheap. Interested to see the results this summer. You have a new subscriber.

[@meeran071]

Excellent comparison.

[@twinwankel]

I used Smart Shield, a 3mm thick reflective roll from Azn. It worked well. The garage used to be sweltering in the summer and now its bearable. I also put a dark window film on the glass panels and that helps a lot. I do like the glass panels to bring in sunlight even though they allow more radiant energy in. I spent about $90 on the reflective roll and about $20 on the window tint. I have a rolling floor HVAC in the garage when I work there in the summer and winter. I love my man cave. It has everything for a good shop.

[@LRN2DIY]

That sounds awesome. No solution is perfect, including all of the ones I tested, and your setup sounds fantastic. I really wish I had windows in my door but we bought the home as-is and that's ok. Enjoy that man cave!

[@nostradamus7648]

What brand and model HVAC and has it been reliable?

[@turboflush]

When comparing the percentages.. though the double bubble is the worst.. still not far off. When comparing percents. That custom insulation is interesting.

[@sam08330]

Thx so much for the information and your time, appreciate it! Great information!

[@BigSteelThrill]

most excellent offering 👍

[@jhors7777]

Thank you for posting this helpful video

[@chrisperrywv]

Dude- you’re in my head! Garage cooling AND decorative hardware are both on my list. Haha

[@BriBo24x7]

Great video! I'm sure that was a lot of work. One thing I've noticed about our insulated garage door is the metal parts of the door (that you see on the inside of the garage) radiate a lot of heat and can still burn you. Yes, the idea is to knock out the largest source of heat, which you do with the insulation panels, but it would be nice if there was a way to minimize the metal parts also. I've installed radiant barrier film in the attic, and I've considered covering the inside of my door with that. Does anyone know of another solution?

[@josh90301]

What you are talking about is called thermal bridging. I haven't found a great way to solve that problem since the metal hinges need to move, so whatever used would need to be flexable enough and not get in the way.

[@beckibalok6428]

will you do same for winter weather? curious how much warmer interior will be with each of your samples. Thank u.

[@lishajoyh8154]

Knowledge is power thanks for sharing

[@JoeTheDIY]

Your videos are just awesome! I'm just learning, but you're a pro.

[@Greg-McIver]

Great video! If you haven't done it already, compare wall insulation types against closed cell foam insulation.

[@Preciouspink]

Wow that is a lot of effort,impressive

[@stargazer7644]

Infrared thermometers do not measure just where the dot is. They measure in a cone which gets bigger as you get farther away. Since the emissivity of metal is far different from foam, your temp measurements will not be accurate because you're measuring areas beyond the paper. Your IR camera has an emissivity adjustment that you need to set for the material you're measuring to calibrate the readings.

[@AdministrativeReload]

For the panels with a reflective side, it makes a difference which way you orient the reflective side. Face in if you want to keep heat in, face out if you want to keep heat out. The insulated cells could be extra effective for climates that expirience hot and cold extreemes as you could make one side face out and one side face in. Just a thought.

[@beamazing2876]

Your video was simply amazing !

[@ArialStacy]

Hell yes! Thank you Mr. Perfect, for making This video Great content on all videos

[@zlcju]

The Formular NGX does not take 1 minute to install each panel. By the end of my install I got down to about 10-15 minutes per panel.

[@eibach1000]

great video and that involved a lot of work. for the double reflective insulation, did you leave an air gap between the garage door and the insulation? Supposedly about a 0.5 to 1 inch gap makes a big difference. I ask because its the cheapest, lightest, and easy to install. Curious to see results for a double layer of the reflective insulation with an air gap between the garage and an air gap between the two layers. I think it would be similar to Freds DIY insulation result but lighter and easier to install

[@jesusfreakster101]

Looked up the winner today and it’s 43 dollars per 4x8 sheet.

[@MyDubydoo]

Any thoughts to maybe checking how well the garage door manufacturers insulation works? Pretty affordable. Made for the doors, and look like it is supposed to be there. 5 of your 6 options actually call for different springs than a non insulated door torsion system. I get what you are trying to do, but you will cost the viewer more money by not knowing what IPPT is and how its calculated.

[@exclusivelynyc]

Excellent, excellent video. Thank you

[@dtsang508]

Just the video I was looking for!

[@Goalsplus]

I don't know how long you had the heater on the outside spot but I think the real test, which would be pretty hard to do, is eight hours in the heat.

[@LRN2DIY]

That would be good to try, yeah. There are many ways to improve this test, like testing it on a south facing garage door in Las Vegas in July as well as an extreme cold test. I feel like this gave me a good idea at least, so it's a start.
