Garage Door Insulation - Customer Project - San Antonio, Texas

This project was sent in by a customer last June and we submitted it to our garage door insulation project area on the website. Recently we spoke with our customer again and this time he is helping a neighbor insulate his garage door.

Here is a brief excerpt of our correspondence that we wanted to share as it clearly shows the effectiveness of using reflective insulation in the right applications. Thanks again for the pictures and write up of your project. We look forward to seeing pictures of your neighbor's garage door as well.

"With my second floor living space directly over the garage it was been awesome to have it maintain a perfectly balanced temp in there.  I don't run the AC/Heat all that often and it still stays pretty close in there due to the insulation. Pretty awesome stuff and cheap enough that everyone should do it."

Project File - Garage Door Insulation

Who: Customer What: Insulate Garage Door Why: Minimize radiant heat gain through door. Customer has workshop and utilizes air conditioning Where: Greater San Antonio, Texas How: Insulated on framework from panel to panel. Used ¾” self-tapping screws to hold insulation on. Added pieces on side to trap air (see pictures). Trimmed each panel instead of overlapping material for aesthetics.

Feedback: Customer stated garage is easily 8-12 degrees cooler. Mini split A/C unit installed and only has to drop the temperature 10 degrees not versus 20-22 before the installation.

Our thoughts: This is the best garage door insulation installation we have ever seen. The reason is because the customer is meticulous and understands the mechanics of heat transfer. By applying InfraStop® on the frame of the garage door a generous 2" airspace was created. By blocking the side channels this airspace was preserved. Trapped airspaces are great insulators. This also allows the foil insulation optimal efficiency as well.

By screwing the insulation into the frame at each bend in the door allows for one, a permanent install. There is no worry of tape adhesion to the door not holding up. Construction adhesives can be avoided as well. These are difficult to get off door and will damage the insulation if it ever needs to be removed.

Secondly, by screwing above and below each bending point in the door, it can be open and closed with no obstructions or material rubbing against each other. By removing hardware and reapplying where needed this garage door insulation application not only looks fantastic but performs extremely well too!
