Attic Insulation Levels

Why are other types less suitable.

Attic insulation levels.

Level up insulation is a professional insulation installation company in beverly hills and we offer a wide range of services including insulation installation replacement and removal as well as crawl space and attic insulation. In general to optimally isolate an attic on average an r value of the insulation is required ranging from r 50 to r 60. Add weatherstripping around the perimeter and a sweep to the door of a walk up attic. Inspecting your attic insulation.

Pull down stair or ladder. If i were to build another home i d invest in even better insulation. Insulation levels are specified by r value. Affix rigid foam insulation to the attic side of the hatch or door.

Attic hatch or door. Rigid foam boards trap air or another gas to resist conductive heat flow. If i need storage space in my attic where is the best place. The higher the r value the better the thermal performance of the insulation.

Insulation level are specified by r value. R value is a measure of insulation s ability to resist heat flow. The higher the r value the better the thermal performance of the insulation. R value is a measure of insulation s ability to resist heat traveling through it.

So we have between r36 and r56 in the attic. The floor limits the cellulose to a depth of 12 inches in some places. Add the right kind of insulation. The table below shows what levels of insulation are cost effective for different climates and locations in the home.

The depth varies quite a bit because we have attic trusses and a floor in the attic. Your attic should have a certain amount of insulation in it and the recommended level of insulation for your attic is dependent on where you live. Find your zone on the map and then use the above insulation r value chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces. What type of attic insulation would you recommend.

First things first you need to go up into your attic inspect the condition of the insulation and calculate the current level of insulation. The insulation levels of an attic or of any part of a house are understood through the r value that is the value with which the insulating material is resistant to heat flow. Bulky materials resist conductive and to a lesser degree convective heat flow in a building cavity. The recommended level for most attics is to insulate to r 38 or about 10 to 14 inches depending on insulation type.

Cellulose insulation has an r value of approximately 3 to 3 5 per inch. These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation.
