The Smartest Way to Insulate Your Garage Door: A Complete DIY Guide

When the girls start helping you clean, it's adorable! I love it when my kids want to help me.

Great video Carlos! I appreciate the detail explanation for heat transfer. Thanks

The approach that I've used in 3 houses in blazing Florida is: Buy the 2 inch 4×8 sheets of rigid insulation with the radiant foil on one side (shiny foil goes toward the door). Cut to fit on my table saw with rabbet joints to help it fit into the channels. Its a snug friction fit thatnis slightly fatter than the door. So once you add the stiffener braces, it just snugs everything up! The door barely rattles now as the styrofoam adds a lot of stiffness and deadens the sound a LOT. I also installed an oversized ductless mini split in there as well. So it's quite comfy!

The production quality is excellent for a channel with less than 200 subs. Carlos, you are doing great work!

Great video Carlos! I got lots of good info from it for my identical project and the ways you shared your thoughts for “future Carlos” and after you slept were quite enjoyable and entertaining! Appreciate your level of detail and the fun you and your family put into this video. Keep up the great work! Many thanks, Rob

I’ll definitely look into applying this solution in my own garage. Seeing the difference in temperature from inside and outside was crazy! More comfortable garage temperature = more time working on all the home projects!

Thank you carlos. This is the exact thing I wanted to do to my garage.

cheers for the advice Carlos

Looks so easy with your explanation . Very good info. Thanks

Great video, I appreciate that you showed the mistakes like garage bracing, and what you would have changed like the tape. Subscribed!

Great Video…

5 years ago I did a radiant reflective barrier with an air gap, no foam on my garage door. There is a 20 to 30 degree F difference from the outside of the garage door and the inside temp. I did the same for my ceiling. Now when it's 110 outside it's about 85 to 90 degrees in the garage. That is about as hot as it gets here. So I am happy, I guess when it gets into the 120s in a few more years I will need to foam board up as well.

Awesome!

Bro that Zelda tune!!!! hahahahahah Subscribing for more Zelda tunes, 3D prints like Majora's Mask... oh yes and the DIY content! Great work dude

Me anima a la instalación del aislante!!

Maybe it was just me but I found the background music a bit distracting/loud. Other than that great video, best of luck.

Muy bien explicado!!

It's a nice effort but there is something fairly obvious that you are missing called thermal bridging. The metal frame that extends from the outside of the garage to the inside will still allow a substantial amount of heat transfer and you will still have issues with the garage heating up. It would take a much longer period of time to do so but it's definitely there and you have essentially installed the insulation incorrectly.  What you are aiming for is a continuous surface of insulation with virtually no breaks in it. To do so, you will need to install the insulation over the internal surface of the garage door and you likely don't need to remove any of the parts of the door. You are clearly not going to be able to attach the Festool tracks the way you currently do and you may have a problem with the door mechanism which is why this isn't often done. To be perfectly honest, you likely want a door that was built as an insulated product as retrofitting is not always possible and is always hard. As to radiation, I think you might be over engineering this whole thing. Your garage door is metal and that reduces radiation substantially Having your door painted in a light color also reflects a lot of the radiant heat back so the foil insulation is great but it mostly works because of the air pockets and not the foil.

Throw a little portable AC and heater combo in there and you will be working in luxury conditions

Awsome, I really enjoyed your video 👍🏻👍🏻
