Or 8 Ft. Single Garage Door Insulation Kit - 9' x 7' or 9' x 8' single metal door insulation application with a very efficient fiberglass R-Value. R-Value is a measure of thermal resistance used in the building and construction industry. It is the ratio of temperature difference. Because garages are becoming an extension of the home's active living space, insulating your garage door will keep your garage warmer in the winter and cooler in the summer. It also acts as a sound insulator keeping outside noises out. Easy-to-install, the kit includes: (1) 22' x 37' roll of R-8 vinyl faced fiberglass insulation for a standard metal 1 car garage, 17 self-sticking retainer pins, and 17 retainer pin caps.
