Facing and faced building insulation

摘要

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).
