R Value Wood Garage Door

The higher the r value the greater the insulating properties of the door.

R value wood garage door.

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. 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. What r value should you look for in a new garage door. R value is a measure of thermal efficiency.

Attached but not actively heated or cooled garages should have a garage door with an r value between r 6 and r 9. R value measures how well certain building insulation materials can resist heat. Another thing that effecting the r value is the material of the insulation. 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.
