R Value Of Wood Garage Door

I think so but the reasons may be a little surprising.

R value of wood garage door.

If it s not insulated then an r 6 value will do. R value measures how well certain building insulation materials can resist heat. A door that is never opened is called a wall. There are mainly 2 materials for insulating garage doors polystyrene and polyurethane.

See chart for r value comparisons. When determining how much insulation you need don t guesstimate calculate. Another thing that effecting the r value is the material of the insulation. Actively cooled or heated garages should have a garage door with an r value of r 13 or higher to save on energy costs.

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. Below is a list of our garage doors and the r value of each one. That s particularly true if you have a heating system in the garage. For example the door s description may read 16 ft x 7 ft r value 6 5.

In general a higher r value means better insulation but there s more to it than that. A 7 foot x 8 foot wooden garage door ranges from 974to 1 468. 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.

A 2 1 4 inch solid core wooden door for example has an r value of 3 70. Know exactly how much you need with our project calculators. Extra job supplies needed range from 24to 28wooden doors require additional equipment such as miter saws and sanders. The higher the r value the greater the insulation performance.

The total price ranges from 740to 1 140. Basic labor for 5 4 hours of installation is between 340and 412. R values climb as thickness of the material increases. 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.

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. 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. However you also need to analyze the door s cold resistance before making a purchase decision. Attached but not actively heated or cooled garages should have a garage door with an r value between r 6 and r 9.
