R Value Wood Garage Door

In general a higher r value means better insulation but there s more to it than that.

R value wood garage door.

1 3 8 and the other model is 2. That s particularly true if you have a heating system in the garage. Actively cooled or heated garages should have a garage door with an r value of r 13 or higher to save on energy costs. 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. A 2 1 4 inch solid core wooden door for example has an r value of 3 70. When determining how much insulation you need don t guesstimate calculate. See chart for r value comparisons.

If it s not insulated then an r 6 value will do. Attached but not actively heated or cooled garages should have a garage door with an r value between r 6 and r 9. However you also need to analyze the door s cold resistance before making a purchase decision. An r value of 16 is not twice as good as an r value of 8.

R value measures how well certain building insulation materials can resist heat. The higher the r value the greater the insulation performance. 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. Higher is better when looking at garage door r values but it s not the only factor to consider.

R values climb as thickness of the material increases. Know exactly how much you need with our project calculators. A garage door s r value represents its ability to slow the transmission of heat. A value of r 16 offers a 5 reduction in heat flow and a 5 improvement in energy efficiency over an r value of 8.
