Abstract
A composite building material for preventing water and moisture from remaining trapped within walls and roofs of building which includes a weather barrier fixedly attached to a three-dimensional matrix filamentous mat manufactured of a polymeric material. 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 of other building materials without inhibiting the ability of the mat to allow liquids and gases to flow therethrough.
Claims27
A method for constructing a building structure comprising:
- providing a plurality of spaced studs;
- securing a sheathing to the studs;
- providing a composite building material comprising an integral unitary member including a polymeric 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,
- securing the composite building material to said sheathing;
- and
- securing an external covering to the studs with the composite building material being sandwiched between said sheathing and external covering.
A building structure comprising:
- a framed wall comprising a plurality of spaced studs;
- a composite building material comprising an integral unitary member including a polymeric 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 drainage mat to the weather barrier, wherein said building material is fixedly attached to said spaced studs;
- and
- an external covering fixedly attached to said spaced studs with the composite building material being disposed between said framed wall and external covering.
