Garage Door Insulation
What does insulation do and why is it important?
Insulation
Material that has the ability to reduce heat or cold transmission
Insulation Terms:
BTU
Amount of heat necessary to raise the temperature of one pound of water one degree Fahrenheit.
K-Value
Laboratory determined value of thermal conductance of a material.
R-Value
Ability of a material to retard the transmission of heat. The higher the R-Value, the better the insulating performance.
U-Value
Amount of heat, in BTU, is transmitted through one square foot of material (the door) in one hour at a temperature difference of 1 degree F from one side to the other. The lower the U-value, the better the insulation. |
