Full acoustical enclosures incorporating fiberglass insulation inside of a flexible vinyl outer shell to form custom fit blanket with easy Velcro fasteners for closure. The vinyl shell is shaped and sealed using fast and reliable radio frequency sealing to prevent moisture from wicking into the insulation. Additionally, a septum layer may be incorporated to address lower frequency problems. A high temperature barrier may be used on the inside surface for contact with hot surfaces. For over 20 years, Insul-Fab has been designing, developing, testing, and producing our noise enclosures for use on scroll and reciprocating compressors used in the HVAC industry.
