Protective drainage wraps

Abstract

A protective drainage wrap comprises a polymeric spunbonded portion being adapted to allow water vapor to flow therethrough and a plurality of fibers, filaments, tapes or yarn being attached to the polymeric spunbonded portion. The plurality of fibers, filaments, tapes or yarn forms a plurality of channels to assist in forming a drainage path for draining liquid moisture from the protective drainage wrap.

Benefits of technology

[0009] According to one method, a protective wrap to be used in a building is provided. The protective wrap includes a polymeric spunbonded portion and a plurality of fibers, filaments, tapes or yarn. The polymeric spunbonded portion is adapted to allow water vapor to flow therethrough. The plurality of fibers, filaments, tapes or yarn is attached to the polymeric spunbonded portion and forms a plurality of channels to assist in facilitating a drainage path for draining liquid moisture from the protective drainage wrap. At least one framing member is provided. The protective wrap is installed over at least one of the framing members.

[0010] According to another method, a protective wrap to be used in a building is provided. The protective wrap includes a polymeric spunbonded portion and a plurality of fibers, filaments, tapes or yarn. The polymeric spunbonded portion is adapted to allow water vapor to flow therethrough. The plurality of fibers, filaments, tapes or yarn is attached to the polymeric spunbonded portion and forms a plurality of channels to assist in facilitating a drainage path for draining liquid moisture from the protective drainage wrap. A sheathing is provided and the protective wrap is installed over the sheathing.

[0011] According to one method of forming a protective drainage wrap, the method comprises providing a polymeric spunbonded portion being adapted to allow water vapor to flow therethrough. A plurality of fibers, filaments, tapes or yarn is attached to the polymeric spunbonded portion and forms a plurality of channels to assist in facilitating a drainage path for draining liquid moisture from the protective drainage wrap.

Problems solved by technology

Air infiltration may occur in typical construction through, among other places, sheathing seams and cracks around windows and doors.

Moisture build-up can occur externally in the wall cavity from, for example, leaking exterior finishes or coverings, and cracks around windows and doors.
