DIY Insulated Garage Door

okay this will be a quick review of my diy insulation for my garage door okay this is a run-of-the-mill door nothing special just a basic garage door now i decided to go with foamular one and a half inch insulation and also to put that up you'll probably need pl300 a special type of adhesive just for foam don't use regular adhesive it won't work it'll melt the foam so one of the things i wanted to make sure is that i didn't need to put any more tension around that spring above the garage door so i measured each piece and it's roughly 1.1 pounds so the net weight of the whole project would be roughly 17-18 pounds okay with my door here i've got kind of an odd shape i've got a little lip here on the outside of that door and i also have on the on the bottom side of the door a little trough with the lip as well and i had a couple choices between insulation that uh distance here between the door and the lip is about an inch and a half so i looked at the radiant backed insulation it was okay i just couldn't get it to get an inch and a half thickness and i really wanted to maximize the r value of that door so what i decided to do was just go with the formular inch and a half xps foam it's r i think seven and a half so that seemed to work the problem with the formula is it's very rigid and it it's not subject to bend very easy so what i did is i instead of trying to mill stuff out here i use a piece of foam there and i use that as an insert inside that cavity instead of trying to having to screw around and try and bend that board and break it not that it happened and that was a lot easier to do and the fact that you know if you want to just slide it in don't get the thick inch and a half formula it just won't bend it's too rigid so in that aspect it's kind of a pain to work with but the other good part of it is seven and a half r value so here's the foam board and stuff installed onto my door i just haven't slided underneath that little rail and it turned out really nice that the top sections i actually had to glue because i guess based on the the way the door opens with the garage door opener there's some force on it so i glued those pieces okay so here's the final product luckily i made some decent measurements and i was able to friction fit all the panels into place except for the top ones those had to be glued in so if you know what you're doing and you get accurate cuts you'll be able to friction fit these otherwise you'll have to glue them all okay without further ado here's some of my results i've done brake jobs in my garage in the past and i tell you it gets hot as hell in there and it gets way above what it is on the outside so on this day the max peak was looks like 93 degrees and i also got a sensor inside the garage that measures that temperature so it looks like i peek inside the garage at about 88 at roughly i don't know between five and six o'clock so here's my thermal imager of the outside of the door the outside door gets about 110 degrees ish and so that's a little bit after the sun hits it i didn't get it the exact angle i've got a shadow up there already so this is an east facing door so it gets hot very quickly very fast and as you can see it's uh you're fluctuating here but majority of the doors around 109 110 degrees so it really bakes the inside of that garage okay so now we're on the inside the panels are 81 82 degrees and as you can see the top there the rafters are about 88 and the reason it's not 100 and something degrees as it's on the door is because there's siding in the way so that's absorbing some of the heat but it's basically keeping that garage way cool compared to what it used to be okay this is a little temp sensor i stuck in here to do all my measurements so the time i measured it was 80 degrees in the garage okay these are my winter results i've done some brake jobs in that garage in the winter and i'll tell you the inside temperature can get as cold as the outside because there's no insulation so on this day we had a low of 14 degrees which is a perfect example to show how insulation works here so this is my thermometer inside the garage and it looks like it it bottomed out at about 32 degrees so to illustrate my point i left one of the insulation panels off so i could thermal image the garage door okay with my thermal imager on i'm recording 30 degrees on the back side of the door that's fairly cold and 37 degrees on the insulation panel 36 37 degrees that's a significant difference and especially in a garage that does not have an insulated door heat tends to migrate from a higher potential or a hotter surface to a colder surface so the heat is actually being sucked out of the garage so to speak through that door amongst other things like the uninsulated walls but the door is probably the the biggest heat loss due to the fact there is absolutely zero insulation okay this is a thermal image of my garage door it's pretty freaking cold out here and that yellow spot you can see is where the panel's removed so there's no insulated panel on that section so looking at the garage door we're roughly looks like between 21 and 23 degrees on the door itself and as we pan back over it will be intuitively obvious that that panel is gone that's where the heat is literally heating up the outside of that garage door so there's a four to six degree temperature differential between the door okay here's another snapshot illustration on a different day you can see the the vast difference between temperatures here okay for you gearheads out there this is an absolute must to do in your garage if you like to work in hot and cold seasons so that's all i have hope everybody liked it and inspired you to do a garage diy insulation job and put some more interesting content out
