Composite house wrap

Abstract

A composite house wrap is provided with a high insulation value and including three integral sections or layers. The first or front layer is a reinforcing grid or mesh that functions as a drainage plane and will face the outside cladding. The second or middle layer is a breathable, barrier film, such as a polyethylene (PE) or polytetrafluoroethylene (PTFE), is bonded to the first layer, such as through thermal bonding. The third or rear layer is a perforated foam layer, such as an expanded low density polyethylene foam that is bonded to the middle layer, such as through an adhesive.
