摘要： A building board including a cementitious layer between two fiber mats. At least one fiber mat forms with a polymer film a fiber mat/polymer film laminate. The cementitious layer of the building board contains a reactive water-insoluble polymer which improves binding of the fiber mat/polymer film laminate to the cementitious layer. The building board has a low water absorption and a high level surface finish.

摘要： A building board, particularly a gypsum board, can have a high fastener sealability if protected by the combination of thin layers of an extruded polymer film and a thermoplastic coating layer. The combination of extruded polymer film and thermoplastic coating layer is designed such that the gypsum board can also tolerate overdriven fasteners, thus exceeding the requirements of ASTM D1970-15.

摘要： A building assembly can include a substrate and a water barrier coating film. The water barrier coating film can include a thermoplastic polymer and microporous particles, such as microporous glass beads. The water barrier coating film can provide a good protection towards liquid water but may allow water vapor flow from the substrate through the coating film. The water vapor permeability of the water barrier coating film can be at least 2 US perms as tested according to ASTM E96 (2014) at 21° C. and 50% average relative humidity.
