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.
