This number is calculated as a function of thickness of the insulator and its physical properties.
Garage door r value recommendations.
That s particularly true if you have a heating system in the garage.
The higher the r value the greater the insulating properties of the door.
R value of garage door insulation what is r value.
See chart for r value comparisons.
R value is a measure of thermal efficiency.
A value of r 16 offers a 5 reduction in heat flow and a 5 improvement in energy efficiency over a value of r 8.
It does not offer twice as much thermal resistance or twice the energy savings.
Thus r value is used to show the energy efficiency of a product.
Higher is better when looking at garage door r values but it s not the only factor to consider.
I recommend this range for attached garages that are not conditioned heated or cooled depending on where.
We have several door styles to meet your insulated door needs for both residential and.
Finally the larger the number the better the thermal insulation of the door.
When buying a garage door it s important to consider a few different aspects before worrying about r value.
I recommend this range non insulated and detached garages where you don t spend a lot of time.
For instance r 16 is better than r 12.
For instance if your garage is not attached to the home and is insulated you ll want to look for a door with a rating higher than r 10.
