Garage Door Insulation
What is insulation and why is it important?
Insulation is 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 the 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, transmitted through one square foot of material (the door) in one hour at a temperature difference of one degree Fahrenheit from one side to the other. The lower the U-value, the better the insulation. |
