Abstract:
1. A floor structure consisting of: a wood based laminate; an insulative pad disposed adjacent to wood based laminate, said insulative pad having a fibrous web layer wherein said fibrous web layer comprises reinforcement fibers distributed substantially randomly in a first plane, said reinforcement fibers being interlocked, wherein after the insulative pad is compressed to 75% of its original thickness during a compression set test, the material is then capable of returning to more than 80% of its original thickness and has a compression resistance at a compression of 25% of the original thickness of greater than about 20 psi; a multilayer coextruded film vapor barrier fixably coupled to the insulative pad, wherein the multilayer coextruded film vapor barrier is formed of a pair of external polyamide skin layers, disposed between the polyamide skin layers are internal layers of linear low-density polyethylene, and disposed between the skin layers and the internal layer is an adhesive; and a fastener pierced through the insulative pad and the multilayer coextruded film vapor barrier, forming a hole defined in the multilayer coextruded film vapor barrier, wherein the multilayer coextruded film vapor barrier elastically relaxes, compressing the hole through the multilayer coextruded film vapor barrier around the fastener, and thereby forming a seal between the fastener and the multilayer coextruded film vapor barrier which reduces transport of water vapor through the multilayer coextruded film vapor barrier.
