R36 Attic Insulation

Insulation our building science makes insulation br smarter.

R36 attic insulation.

R value is a measure of insulation s ability to resist heat traveling through it. Most homes are insulated in the attic and any floors located above unfinished basements or crawl spaces. 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. Its expert engineering lets you create the most comfortable environment without compromising your design.

So we have between r36 and r56 in the attic. The depth varies quite a bit because we have attic trusses and a floor in the attic. Insulation decreases the amount of heat entering from outside when it s hot and traps warmth inside when it s cold. 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. The higher the r value the better the thermal performance of the insulation.

The r value indicates how well insulation resists heat transfer.
