Problems solved by technology

However, problems with application can occur, such as the wrong amount of material being applied due to applicator errors, equipment problems, and / or environmental conditions (such as wind, temperature, rain, etc.)
Not only do these issues affect the quality and durability of the air / water barrier, they can also cause significant additional costs in cleaning up and repairing damage to adjacent buildings and cars due to overspray

[0085] Fabrication of outer sheath panels with integrated air / water barrier membranes

[0086] Cementitious panels were prepared with a cementitious core comprising gypsum sandwiched between two fiberglass mats. Allow the cement panel to set.

[0087] The air / water barrier film was formulated with a polymeric binder, calcium carbonate, and antifungal as shown in Table 1. Spray cement panels with an air / water barrier film. A second control coated panel was prepared in parallel.

[0088] The first coated panel was conditioned in the oven at a first temperature zone at a temperature in the range of 100-140°F, then moved to a second temperature zone and further conditioned at a temperature in the range of 160 to 190°F.

[0089] A second control coated panel was conditioned in the same oven, but only in a second temperature zone at a temperature ranging from 160 to 190°F.

[0090] While the first coated panel was fully conditioned with no air bubbles and acquired anti-clogging ...

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to U.S. Patent Application 14 / 198,093, filed March 5, 2014, and claims priority to U.S. Provisional Patent Application 61 / 792,545, filed March 15, 2013, the full disclosure of both applications Incorporated herein by reference. technical field [0003] The present invention relates to a building exterior sheathing panel with an integrated air / water barrier membrane and methods for manufacturing and installing said panel. Background technique [0004] The premise of an air / water barrier as part of a building envelope barrier system is to stop air, water, and other elements from inadvertently entering or exiting the building envelope. External air / water barrier sheet membranes were first introduced in the industry, but because the seams are critical joints, there were several problems associated with installing the sheets in the field. The installation of the sheets does not alwa...
