Garage Door Insulation
What is insulation and why is it important?
Insulation is material that has the ability to reduce heat or cold transmission.
Amount of heat necessary to raise the temperature of one pound of water one degree Fahrenheit.
Laboratory-determined value of the thermal conductance of a material.
Ability of a material to retard the transmission of heat. The higher the R-value, the better the insulating performance.
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.
