Frequently Asked Questions

How Does Insulation Work?

Insulation works by resisting heat flow, which increases your home’s energy efficiency and helps reduce your monthly bills. How it stops heat transfer depends on the type of insulation – for instance, radiant barrier, which is installed in attics, reflects the energy from the sun, while fiberglass traps warm air.

What Is R-Value?

If you’ve ever talked to an insulation contractor, you’ve undoubtedly heard the term “R-value.” Basically, the R-value of a certain type of insulation refers to how effective it is at stopping heat transfer! The R-value depends on the material, thickness, and density of the insulation, and of course, installation (improperly installed insulation is almost like having no insulation at all!).
