Insulation facings are a vital part of the total insulation system. In particular, vapor retarders must be used with proper building ventilation to control concealed condensation. In addition, they contribute aesthetic value to a construction project while meeting performance standards such as moisture migration control, light reflectivity and added material strength. Alpha Associates manufactures a full range of high-quality facings for metal building insulation and was the first to develop a paperless vapor retarder that meets industry permeability standards.

NOTE: Alpha metal-building-insulation facings are produced with plastic films containing ultraviolet (UV) inhibitors. However, intense exposure to UV sources such as direct or indirect sunlight and/or high-output UV lighting is not recommended. Intense UV exposure will degrade the plastic film facing.
