CertainTeed offers its tailored hybrid insulation system, which combines insulation products to create a cost-effective way to provide superior air resistance and moisture control. This is one of the best ways to lower utility bills and save energy. One example of the hybrid system involves the use of CertaSpray® Closed-Cell Spray Foam Insulation, OPTIMA® Blow-In Insulation and MemBrain, an advanced smart vapor retarder which allows a home to breathe better. These products deliver an air barrier and superior R-value at a significant cost savings compared to a foam-only approach. For more information, visit www.certainteed.com.
