Abstract
Building panels, assemblies of building panels, and associated methods are provided. A building panel includes a structural core, such as a set gypsum core, at least one filamentous scrim associated with the core, and a nonwoven mat facer.
Claims32
A roofing panel, comprising:
- a set gypsum core;
- a filamentous scrim associated with the set gypsum core, the filamentous scrim comprising a mesh constructed of elongated fiberglass yarns defining a plurality of openings therebetween, wherein the mesh comprises two sets of approximately parallel elongated fiberglass yarns spaced from one another, with the two sets being disposed approximately perpendicularly to one another, wherein each of the elongated fiberglass yarns has a width or diameter of from about 0.05 inch to about 0.5 inch, wherein the filamentous scrim has a weight of from about 4 oz/yd2 to about 25 oz/yd2;
- and
- a nonwoven fiberglass mat facer associated with the filamentous scrim,
- wherein the roofing panel displays a wind uplift resistance between 120 lb/ft2 and 270 lb/ft2, for a ¼ or ⅝-inch panel on a roofing assembly having 8 or fewer fasteners.

A method of manufacturing a roofing panel, comprising:
- associating a filamentous scrim with a nonwoven fiberglass mat facer, the filamentous scrim comprising a mesh constructed of elongated fiberglass yarns defining a plurality of openings therebetween, wherein the mesh comprises two sets of approximately parallel elongated fiberglass yarns spaced from one another, with the two sets being disposed approximately perpendicularly to one another, wherein each of the elongated fiberglass yarns has a width or diameter of from about 0.05 inch to about 0.5 inch, wherein the filamentous scrim has a weight of from about 4 oz/yd2 to about 25 oz/yd2;
- associating the filamentous scrim and nonwoven fiberglass mat facer with a gypsum slurry;
- and
- allowing the gypsum slurry to set to form at least a portion of a set gypsum core,
- wherein the roofing panel displays a wind uplift resistance of between 120 lb/ft2 and 270 lb/ft2, for a ¼ or ⅝-inch panel on a roofing assembly having 8 or fewer fasteners.
