As a homeowner, it’s important to know a thing or two about insulation and what type of insulation is right for your home. Insulation helps slow down heat movement or heat transfer in a home.

When it gets warmer outside, it slows the hot outside temperatures and keeps it from entering your home. Even if you know how insulation works, there are several different types of insulation.
