R value of wood garage door.

Shoppers may get the impression that this number is important and it is but most are unsure about what it is or why they should even pay attention to it when choosing a garage door. R values climb as thickness of the material increases. A 2 1 4 inch solid core wooden door for example has an r value of 3 70. If you have ever shopped for a new garage door you have probably come across an r value.

Extra job supplies needed range from 24to 28wooden doors require additional equipment such as miter saws and sanders. See chart for r value comparisons. Between 9 18 4 the difference between the r values is caused by the thickness of the doors 1 model is 1 3 8 and the other model is 2. Basic labor for 5 4 hours of installation is between 340and 412.

The r value of a 1 3 4 inch wood door is 3 03. A 7 foot x 8 foot wooden garage door ranges from 974to 1 468. In general a higher r value means better insulation but there s more to it than that. If your garage is not detached then the garage is probably insulated and you ll want a garage door with an r 12 value.

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. I think so but the reasons may be a little surprising. Should you be concerned about r value in choosing your garage door. 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.

There are mainly 2 materials for insulating garage doors polystyrene and polyurethane. If you were living in an extremely cold climate and never intended to open your garage door it could be very significant but the r value of an open door immediately becomes zero. That s particularly true if you have a heating system in the garage. If it s not insulated then an r 6 value will do.

The total price ranges from 740to 1 140. Another thing that effecting the r value is the material of the insulation. 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.

Actively cooled or heated garages should have a garage door with an r value of r 13 or higher to save on energy costs. Below is a list of our garage doors and the r value of each one. For example the door s description may read 16 ft x 7 ft r value 6 5. A door that is never opened is called a wall.
