Frequently asked questions
What is R Value?
An insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value -- the higher the R-value, the greater the insulating effectiveness. The R-value depends on the type of insulation, its thickness, and its density. The R-value of some insulations also depends on temperature, proper installation, aging, and moisture accumulation.

Air Barrier vs Vapor Barrier
Air barriers are designed to prevent the flow of air, and the moisture attached to it, from entering a building envelope. A vapor barrier only aims to prevent the transport of moisture by vapor diffusion into a home’s building envelope. Notably, the amount of moisture carried by airflow is 50 to 100 times greater than that carried by vapor diffusion. According to the U.S. Department of Energy, "air movement accounts for more than 98% of all water vapor movement in building cavities.” Generally speaking, it is recommened to maximize the air tightness of a building, but to strategically limit vapor sorption to allow a home to adsorb/release water vapor at a controlled rate.
