Abstract
A composite drainage mat for preventing water and moisture from remaining trapped within walls and roofs of buildings which includes a weather barrier fixedly attached to a three-dimensional matrix filamentatious mat of a thermoplastic polyamide resin such as Nylon 6. The mat contains a great number of voids for permitting gas and liquid such as water to flow therethrough. The mat possesses a crush-resistance which allows the mat to withstand the compressive force of other building materials without inhibiting the ability of the mat to allow liquids and gases to flow therethrough.
Claims18
A composite weather barrier for use in a building structure, said composite weather barrier comprising:
- a weather barrier;
- a mat formed of an open, three dimensional matrix of plastic filaments formed in an overlapping irregular looped and intermingled fashion;
- and
- a securement means for attaching the mat to the weather barrier to form said composite weather barrier, wherein said securement means is selected from the group consisting of (i) a plurality of spaced adhesive spots, and (ii) a plurality of substantially parallel adhesive strips.
A method for constructing a building structure comprising:
- providing a plurality of spaced studs;
- securing a sheathing to the studs;
- providing a composite weather barrier comprising an integral unitary member including a weather barrier, a mat formed of an open, three dimensional matrix of plastic filaments formed in an overlapping irregular looped and intermingled fashion and a securement means for attaching the mat to the weather barrier, wherein said securement means is selected from the group consisting of (i) a plurality of spaced adhesive spots, and (ii) a plurality of substantially parallel adhesive strips;
- securing the composite weather barrier to said sheathing;
- securing an external covering to the studs with the composite weather barrier being sandwiched between said sheathing and said eternal covering.
