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).
