(Video) Insulating Your Garage DoorFebruary 26th 2015
Q: Our garage doors seem to be of a fairly light material, which tends to let in a lot of cold air in the winter and hot air in the summer. Is there any way to insulate these doors to solve this problem?
A: Metal garage doors are generally made of light material to make it easier for them to go up and down.
This material allows a lot of cold or heat to radiate into the garage.
To correct this, insulation can be applied to the inside of the door. Bat or rigid foam insulation does not work, as it would add too much bulk and weight and impede proper operation of the door.
The product to use is a foil insulation that can be attached to the back of the door with Velcro. This will reflect the cold or heat out, keeping the inside of your garage more comfortable.
Note: A regular bathroom exhaust fan installed in the garage wall approximately 18 to 24 inches off the floor will keep relative humidity under control, and prevent metal items such as tools and lawn or garden equipment from rusting.
