R Value Wood Garage Door

A 2 1 4 inch solid core wooden door for example has an r value of 3 70.

R value wood garage door.

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. R value is a measure of thermal efficiency. Higher is better when looking at garage door r values but it s not the only factor to consider.

R value measures how well certain building insulation materials can resist heat. What r value should you look for in a new garage door. When determining how much insulation you need don t guesstimate calculate. We have several door styles to meet your insulated door needs for both residential and commercial applications.

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. 1 3 8 and the other model is 2. A higher r value means a slower transmission of heat which means less cold air leaking into your garage in the winter and less heat invading your garage in the summer. It does not offer twice as much thermal resistance or twice the energy savings.

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 value of r 16 offers a 5 reduction in heat flow and a 5 improvement in energy efficiency over a value of r 8. The higher the r value the greater the insulating properties of the door.

Attached but not actively heated or cooled garages should have a garage door with an r value between r 6 and r 9. See chart for r value comparisons. 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.
