An attached garage that s on the chilly side can make it hard to keep adjoining rooms comfortable without driving up your heating bill as the cold air passes through the walls and makes. The floor of your garage is probably built on a slab which means that it isn t insulated and is an ongoing source of energy transference.

Generally these will offer the highest levels of insulation when installed fully behind a garages structural opening and will usually provide a u value of between 1 4 and 2 w m k when fitted. Higher r values mean that less heat passes through the door. Garage door insulation is of limited value anyway given the other areas of the garage that are equally problematic in terms of heat loss. Installed u factor a tested value of actual energy loss whether heat or cold of an installed door wall or window assembly.

Here is a brief definition of each. If you are shopping for a garage door with insulation you may see a few different numbers provided that measure the effectiveness of the insulation. An r value is a measure of how effective a material is at insulating a garage door against heat loss. The effectiveness of the insulation is expressed as an r value which is a measure of thermal resistance to heat flow.

Model 5740 17 5 r value. Most garage door insulation has an r value of between r 8 and r 12 because it is so thin to fit the space. The lower the number the lower the energy loss and therefore the better the thermal performance. Model 5720 12 76 r value.

Classic steel model 8500 has the highest level of garage door insulation for our residential doors with an r value of 16 22. Garage door insulation use a special foil backed blanket insulation to fit over the inside of the garage door. U factor will vary between 0 66 and 1 00 depending on finish and color selection. Polyurethane garage door insulation provides thermal efficiency 9 31 r value.

Thermacore construction provides a continuous layer of foamed in place cfc free polyurethane garage door insulation sandwiched between two layers of corrosion resistant steel for maximum thermal efficiency. The higher the r value the better the insulation in the door.
