Embodiment Construction

[0029]In summary, the present invention relates to a composite house wrap 10 is provided with three integral sections or layers 20, 30 and 40 as described below. The house wrap 10 according to the present invention will provide barrier protection plus moisture vapor transmission and an insulation R-value of approximately R2 or higher. The terms about or approximately or similar terms should be read as meaning within ten percent within this application. This house wrap 10 is specifically designed to add enhanced insulating characteristics as opposed to conventional house wraps, while maintaining a cost effective and easy to handle house wrap.

[0030]The house wrap 10 has a total thickness of about 25-30 mils, generally less than 40 mils, preferably less than 75 mils and effectively always less than 175 mils. The house wrap 10 can be attached to a building in any conventional fashion, such as nail guns, or the like. The house wrap 10 has the flexibility and durability that is comparable...

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.

Description

RELATED APPLICATION[0001]The present invention claims priority of U.S. Provisional Patent Application Ser. No. 61 / 138,573 entitled “Composite House Wrap” filed Dec. 18, 2008.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a composite house wrap used generally in building construction.[0004]2. Background Information[0005]House wrap is a worldwide multi-billion dollar yearly industry. The phrase “House wrap” (also called “housewrap”) has been defined as inclusive of all synthetic materials effectively designed for the replacement of traditional sheathing tar paper. These materials are all lighter in weight and usually wider than asphalt designs, so contractors can apply the material much faster to a house shell. A conventional house wrap is described as functioning as a moisture barrier, preventing rain from getting into the stud wall construction while allowing moisture vapor to pass out from the house's interior living space to the ex...
