Abstract:

A construct of selectively ventable insulation. The construct includes a substrate layer of a cohesive, bulky web of entangled fibers, with the web material defining a first side and an opposing second side of the substrate layer. The web material has an undulated form based on lapping of the web material. A covering layer is disposed adjacent to and coextensively over the first side of the substrate layer. A plurality of slits are formed in the covering layer. The slitted covering layer is configured so that when it is in a first condition, the slits are closed, and when in a relatively tensioned second condition, the slits become open perforations through the covering layer, thereby allowing venting of air or other fluid from a side of the covering layer that is adjacent the first side of the substrate layer. In another embodiment, the construct includes a substrate layer of a cohesive, bulky web of entangled fibers, with the web material defining a first side and an opposing second side of the substrate layer. The substrate layer may or may not have undulations. A plurality of slits are formed in the substrate layer so that when it is in a first condition the slits are closed, and when in a relatively tensioned second condition, the slits become open perforations through the substrate layer, thereby allowing venting of air or other fluid from the first side of the substrate layer to its second side.
