摘要： The present disclosure relates generally to building surface joint supports, for example, suitable for covering a seam between two building surface panels. In certain aspects, the disclosure provides joint supports that include an elongate layered structure having inside and outside surfaces, the elongate layered structure including a support strip that includes first and second elongate flanges. In certain embodiments, the elongate layered structure also includes an inner facing sheet disposed on the inside surface of the support strip; and an outer facing sheet disposed on the outside surface of the support strip, wherein the each of the inner facing sheet and the outer facing sheet is formed from a fibrous polymer material. In other embodiments, each flange of the first and second elongate flanges includes apertures therethrough, each aperture having a width that extends laterally across at least 50% of the width of the respective flange; and the elongate layer structure also includes an outer facing sheet disposed on the outside surface of the support strip.

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.
