A protective drainage wrap comprises a cross-woven material portion, cross-laminate material portion or mesh material portion in first and second directions and a breathable solid layer portion. The material in the first and second directions comprises a polyolefin, polyester, nylon or combinations thereof. The first direction being roughly perpendicular to the second direction. The cross-woven, cross-laminate or mesh material portions being adapted to facilitate a drainage path. The breathable solid layer portion is attached to the cross-woven material portion, cross-laminate material portion or mesh material portion. The breathable solid layer portion is adapted to allow water vapor to flow therethrough.

Protective drainage wraps

An underlayment with improved drainage is disclosed. Particularly, the invention relates to an underlayment board having a first surface and a second surface, wherein the board further includes a top edge and a bottom edge and includes at least one channel defined in the first surface with each of the at least one channel extending from the top edge to the bottom edge to form a drainage path therebetween. More particularly, the underlayment board can include at least one funnel defined proximate at least the top edge or the bottom edge, wherein the at least one funnel is in fluid communication with a corresponding one of the at least one channel. A method of finishing an exterior of a structural substrate and a building assembly are also disclosed.

Underlayment with improved drainage

A protective drainage wrap includes a mesh and a coating applied to the mesh. The coating is applied to the mesh to form a plurality of interstices, the interstices being configured to facilitate transfer of water vapor therethrough. The mesh includes material extending in a first direction and in a second direction. The material in the first direction includes a polyolefin, polyester, nylon or combinations thereof and has a first thickness. The material in the second direction includes a polyolefin, polyester, nylon or combinations thereof and has a second thickness. The second thickness is at least about twice the first thickness so as to assist in providing drainage for moisture build-up. The material in the second direction can be yarn. The coating includes a polyolefin, polyester, nylon or combinations thereof. A process for the preparation of the protective drainage wrap is provided.

A sheathing adapted to be fastened to at least one wall supporting structure comprises at least two layers. The first layer comprises a polymeric foam layer. The second layer comprises a polymeric scrim and is located adjacent to the first layer. The second layer reinforces its periphery so as to inhibit the failure of the scrim. The reinforced periphery may include a selvage tuck or a folded-edge.

Polymeric foam scrim sheathings

A protective drainage wrap comprises a first portion, a second portion and a solid sheet portion. The first portion comprises cross-woven or cross-laminate material in the machine direction and in the transverse direction. The material in the machine direction comprises a polyolefin, polyester, nylon or combinations thereof and has a first thickness. The material in the transverse direction comprises a polyolefin, polyester, nylon or combinations thereof and has a second thickness. The second thickness is at least about 2 times greater than the first thickness so as to assist in providing drainage for moisture build-up. The second portion is a coating comprising a polyolefin, polyester, nylon or combinations thereof. The first and second portions are located adjacent to each other. The solid sheet portion comprises a polyolefin, polyester, nylon or combinations thereof. The solid sheet portion is attached to at least one of the first portion and the second portion.

Method for producing protective drainage wraps

A sheathing adapted to be fastened to at least one wall supporting structure comprises at least two layers. The first layer comprises a polymeric foam layer. The second layer comprises a polymeric scrim and is located adjacent to the first layer. The second layer has a first portion and a second portion. The second portion is located near the periphery of the polymeric scrim layer. The first portion has a first machine direction (MD) scrim count number and a first transverse direction (TD) scrim count number, and the second portion has a second MD scrim count number and a second TD scrim count number. At least one of the second MD scrim count number and the second TD scrim count number is greater than the respective first MD scrim count number or the first TD scrim count number so as to inhibit failure of the scrim.

According to one embodiment, the material in the transverse direction is yarn.

A method for using a support backer board system and siding. The support backer board system comprises at least a first layer. The first layer is made from a material selected from the group consisting of alkenyl aromatic polymers, polyolefins, polyethylene terephthalate, polyesters, and combinations thereof. The board system is thermoformed into a desired shape with the desired shape being generally contour to the selected siding. The siding is attached to the board system so as to provide support thereto. In one process, the siding may be vinyl.
