Construction

 

Compac is one of the leading manufacturers of vapor retarder facings and jacketing used in the insulation industry.  Applications include residential and building insulation, fiberglass duct wrap and board, metal building, and mechanical insulation.  We also produce a complete line of pressure sensitive insulation tapes, many of which utilize our own facings. Our products are easily applied and provide pleasing insulation finishes.  They protect insulation against the effects of moisture ingress, which can lead to condensation and corrosion, and help assure the long-term thermal performance of buildings and systems.
