R36 Attic Insulation

So we have between r36 and r56 in the attic.

R36 attic insulation.

The floor limits the cellulose to a depth of 12 inches in some places. Cellulose insulation has an r value of approximately 3 to 3 5 per inch. R value is a measure of insulation s ability to resist heat traveling through it. R values like r 38 are used by the construction industry to describe the thermal resistance of insulation materials like those used to insulate your attic when you are looking at an r 38 insulation you are actually reading a description of its resistance rather than size or thickness of the material.

Insulation level are specified by r value. Insulation decreases the amount of heat entering from outside when it s hot and traps warmth inside when it s cold. The r value indicates how well insulation resists heat transfer. The table below shows what levels of insulation are cost effective for different climates and locations in the home.

From schools to businesses to family homes our insulation works everywhere. Most homes are insulated in the attic and any floors located above unfinished basements or crawl spaces.
