Do you need radiant barrier installation in Southern California? Sierra Insulation Contractors is the company to call! We work with builders, contractors and building managers to install radiant barriers in commercial spaces, for both retrofit and new construction projects. Radiant barrier insulation is made of a reflective surface (like aluminum foil) applied to a substrate material. The substrate materials range from cardboard to other insulation materials. This type of insulation is installed right under the roofline and helps buildings reflect (rather than absorb) sunlight, keeping spaces cooler and more comfortable and helping maximize energy efficiency and savings.
