Most garage door insulation has an r value of between r 8 and r 12 because it is so thin to fit the space.
What r value insulation do i need for garage door.
When determining how much insulation you need don t guesstimate calculate.
Without these weatherproofing features the cold or heat will reduce the energy efficiency of the door.
Some materials provide better insulation than others.
The floor of your garage is probably built on a slab which means that it isn t insulated and is an ongoing source of energy transference.
In garage doors the higher the r value the better the door will be at stopping heat loss.
The thermal resistance value of a garage door doesn t mean much if the door isn t equipped with effective thermal breaks and suitable weatherstripping around and between the door sections.
This adds insulation to the garage door without impeding its functionality.
Insulation materials are designed to stop the flow of heat.
If your garage is not detached then the garage is probably insulated and you.
The r value is just a measurement of how well the materials are working.
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.
Do different insulation materials affect the r 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.

Garage door insulation is of limited value anyway given the other areas of the garage that are equally problematic in terms of heat loss.
