That s particularly true if you have a heating system in the garage.

See chart for r value comparisons. The r value of a 1 3 4 inch wood door is 3 03. Between 9 18 4 the difference between the r values is caused by the thickness of the doors 1 model is. A 2 1 4 inch solid core wooden door for example has an r value of 3 70.

An r value of 16 is not twice as good as an r value of 8. R values climb as thickness of the material increases. 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. 1 3 8 and the other model is 2.

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. Another thing that effecting the r value is the material of the insulation. However you also need to analyze the door s cold resistance before making a purchase decision. It does not offer twice as much thermal resistance or twice the energy savings.

Know exactly how much you need with our project calculators. In general a higher r value means better insulation but there s more to it than that. A garage door s r value represents its ability to slow the transmission of heat. Attached but not actively heated or cooled garages should have a garage door with an r value between r 6 and r 9.

Overhead door corporation uses a calculated door section r value for our insulated doors. We have several door styles to meet your insulated door needs for both residential and commercial applications. The higher the r value the greater the insulating properties of the door.

If your garage is not detached then the garage is probably insulated and you ll want a garage door with an r 12 value. R value of garage door insulation what is r value.

The higher the r value the greater the insulation performance. Today s garage doors with polyurethane insulation will have an r value of 12 18 garaga s residential garage doors provide up to r 18 but you also want to choose a door that has otherwise good construction. When it comes to r values for garage doors the higher the better.
