Patent attributes
A building comprises an exterior substrate, such as an exterior prepped for application of a building material and one or more expansion and control joints. A window or door casing has a surface extending above the substrate, and a casing bead control joint with a spacer strip defining a space between the casing and the control joint. For example, the strip is removable by peeling away the strip from an adjacent flange, which may have an optional permanent gasket or back rod preinstalled for filling the space between the casing and the control joint. The control joint may be combined with one or more other expansion or control joints fixed to the exterior of the substrate and a layer of a building material may be applied on the substrate and overlapping a portion of the expansion and control joints.
