High-Performance Fiberglass Building Insulation Batts are intended for use in walls and cathedral ceilings where maximum thermal performance is desired and limited space is available.

Installing High-Performance Fiberglass Building Insulation is an easy, cost effective method to help conserve energy in the residential and commercial new construction, remodeling and reinsulation markets. In addition to its thermal properties, High-Performance Fiberglass Building Insulation also provides excellent acoustical performance. It is compression packaged for ease of handling, and its broad availability of R-values, sizes and facings ensures the right product for the job. High-density sidewall batts are available in sizes to fit standard construction without loss of R-value due to compression.

High-density cathedral ceiling batts allow an airspace between the insulation and roof deck for ventilation. These batts meet the energy-saving requirements of today's codes without requiring changes in construction techniques.
