  • Patent number: 6579586
    Abstract: A fibrous insulation batt is encapsulated within an envelope to form an encapsulated insulation batt assembly. The envelope has pressure sensitive adhesive on lateral flanges or surfaces of the envelope for securing the encapsulated insulation batt assembly to spaced-apart frame members defining a cavity to be insulated. Release liners, on surfaces of the envelope or the lateral flanges, which overlay and are releasably secured to the pressure sensitive adhesive, are removed from the pressure sensitive adhesive immediately prior to bonding the encapsulated insulation batt assembly to the spaced-apart frame members. Preferably, the release liners for the pressure sensitive adhesive are contact areas on the surfaces of the envelope or the lateral flanges coated or otherwise treated with a release agent.
