New Rochelle Drywall Pros installs exterior gypsum sheathing as the weather-resistant substrate behind commercial facades. Exterior sheathing is the layer that ties the building's structural framing to its cladding and air-and-water barrier, so it has to be the right glass-mat panel, fastened to the specified pattern, and detailed for the wall system that follows. We hang DensGlass and comparable exterior gypsum sheathing on light-gauge and structural metal framing to the architect's exterior-wall assembly. Getting this substrate right is what lets the barrier and cladding trades build a sound, durable wall.
Exterior sheathing uses glass-mat-faced gypsum panels such as DensGlass that resist moisture and mold far better than paper-faced board when exposed during construction. We hang the specified sheathing on the exterior metal framing, fastening to the pattern and edge distance the assembly requires. Using the correct glass-mat panel is what lets the sheathing tolerate weather exposure before the cladding closes it in.
Sheathing only performs if it is fastened to sound, correctly spaced framing, so we set the exterior light-gauge or structural studs true before the panels go up. We fasten the sheathing to the specified pattern so it resists wind load and gives the barrier and cladding a flat, stable substrate. Straight framing and a correct fastening pattern are the foundation of a durable exterior wall.
The sheathing is one layer in a larger exterior wall assembly that includes the air-and-water-resistive barrier, insulation, and cladding. We coordinate our sheathing joints and details with the barrier and cladding trades so the transitions land cleanly and the wall stays continuous. Setting the substrate to suit the trades that follow keeps the whole exterior assembly on schedule and watertight.
You can find our exterior sheathing crews on commercial facades in New Rochelle, Mamaroneck, Larchmont, Yonkers, Elmsford, and Tarrytown.
