R Value Of Wood Garage Door

If your garage is not detached then the garage is probably insulated and you ll want a garage door with an r 12 value.

R value of wood garage door.

A 2 1 4 inch solid core wooden door for example has an r value of 3 70. Attached but not actively heated or cooled garages should have a garage door with an r value between r 6 and r 9. 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. When determining how much insulation you need don t guesstimate calculate.

In general a higher r value means better insulation but there s more to it than that. See chart for r value comparisons. 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. Extra job supplies needed range from 24to 28wooden doors require additional equipment such as miter saws and sanders.

If it s not insulated then an r 6 value will do. I think so but the reasons may be a little surprising. Below is a list of our garage doors and the r value of each one. There are mainly 2 materials for insulating garage doors polystyrene and polyurethane.

That s particularly true if you have a heating system in the garage. R values climb as thickness of the material increases. A door that is never opened is called a wall. For example the door s description may read 16 ft x 7 ft r value 6 5.

The r value of a 1 3 4 inch wood door is 3 03. Should you be concerned about r value in choosing your garage door. R value measures how well certain building insulation materials can resist heat. The higher the r value the greater the insulation performance.

However you also need to analyze the door s cold resistance before making a purchase decision. 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 value of r 16 offers a 5 reduction in heat flow and a 5 improvement in energy efficiency over a value of r 8. If you have ever shopped for a new garage door you have probably come across an r value.

Another thing that effecting the r value is the material of the insulation. A 7 foot x 8 foot wooden garage door ranges from 974to 1 468. 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.
