Fiberglass Batt Insulation

Fiberglass batt insulation is one of the most common and widely used insulation products in the building industry, making it a trusted choice for homes and commercial buildings alike. Available in a variety of thicknesses and R-values—typically ranging from R-13 to R-38 depending on the application—it provides reliable thermal performance for walls, floors, ceilings, and attics. In addition to improving energy efficiency, fiberglass batt insulation offers moderate sound reduction, with wall assemblies commonly achieving STC ratings of 35–45 when properly installed. Its affordability, proven performance, and widespread availability have made fiberglass batt insulation a dependable standard for new construction and remodeling projects.
