A: Diamond Certified insulation contractors use top-quality brands like GAF, Applegate Insulation, Owens-Illinois, Knauf Insulation and Kingspan Insulation.
Q: What types of basement insulation do insulation contractors offer?
A: Insulation contractors offer two types of radiant barrier insulation: foil-based and fiber-based.

Fiber-based radiant barrier insulation is made from a reflective material, such as metalized polyethylene, that is installed between the attic and the living area of the home.
