R Value Of Wood Garage Door

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

R value of wood 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. 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. 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.

That s particularly true if you have a heating system in the garage. A 7 foot x 8 foot wooden garage door ranges from 974to 1 468. If it s not insulated then an r 6 value will do. The r value of a 1 3 4 inch wood door is 3 03.

Extra job supplies needed range from 24to 28wooden doors require additional equipment such as miter saws and sanders. Actively cooled or heated garages should have a garage door with an r value of r 13 or higher to save on energy costs. The total price ranges from 740to 1 140. A door that is never opened is called a wall.

Another thing that effecting the r value is the material of the insulation. 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. If you have ever shopped for a new garage door you have probably come across an r value. 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.

There are mainly 2 materials for insulating garage doors polystyrene and polyurethane. See chart for r value comparisons. R value measures how well certain building insulation materials can resist heat. 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 example the door s description may read 16 ft x 7 ft r value 6 5. Should you be concerned about r value in choosing your garage door. However you also need to analyze the door s cold resistance before making a purchase decision. I think so but the reasons may be a little surprising.

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. Know exactly how much you need with our project calculators. R values climb as thickness of the material increases. When determining how much insulation you need don t guesstimate calculate.
