The facing of a faced insulation layer has Z-folded, double-folded, or single-folded lateral tabs extending the length of the facing sheet along or spaced inwardly from lateral edges of the facing sheet. Each lateral tab has multiple segments. One of the segments of each lateral tab has an adhesive thereon that can be exposed and extended beyond one of the lateral edges of the insulation layer for bonding the faced insulation layer to a framing member. Where the blanket is separable into sections, the facing has pairs of separable tabs that separate when the blanket is separated to expose surfaces of the separable tabs with adhesive thereon. The adhesive may be microencapsulated or have microencapsulated constituent(s).

Facing and faced building insulation

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.
