A composite structural board having a structural board and a water-resistant barrier (WRB) sheet, and a wall system comprising same, wherein a face of the structural board is discontinuously attached to the inner face of the WRB sheet solely by a first adhesive, the WRB sheet fully covering the face of the structural board; wherein the unattached areas between the face of the structural board and the inner face of the WRB sheet define paths by which a liquid can move between the face of the structural board and the inner face of the WRB sheet; in some instances the WRB sheet material extends beyond at least one edge of the structural board forming a WRB sheet flap.

Composite structural board and wall systems containing same

A drainage component having a continuous, extruded mat having an upper face and a lower face. The mat includes a plurality of patterned three-dimensional structures, each structure spaced from all adjacent structures, and the plurality of patterned three-dimensional structures are provided in a plurality of linear rows or columns in a first direction.

Extruded mat

A process for covering, protecting and providing access to mate lines during building construction comprising the steps of preparing a vertical and horizontal mate line closure flap, carrying out a vertical and horizontal mate line access process, carrying out a vertical and horizontal mate line closing process, repeating the vertical and horizontal mate line access and closing processes as required, and carrying out a vertical and horizontal mate line sealing process to complete the building weatherization.

Method for covering and accessing mate lines during building construction

This invention relates to improved sheets of flash-spun plexifilamentary film-fibrils useful in fluid microfiltration and sterile packaging. The sheet material suitable for use in microfiltration of liquids has a permeability that causes a pressure drop of less than 21 kPa at a water flow rate per unit area of 12.55 ml/min/cm.sup.2, and that has a filtration efficiency of 99% of dust particulates in the size range of 1 to 2 microns suspended in a stream of distilled water pumped through the sheet material at a pressure differential of 207 kPa. The sheet material suitable for use in sterile packaging that has a Gurley Hill Porosity of less than 15 seconds and a bacteria spore log reduction value of at least 2.5.
