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 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 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.
