This addition to the Chatham Day School in Chatham, NJ includes a single-slope gymnasium featuring a standing seam roof system and a 10" fiberglass simple saver insulation system. This pre-engineered metal building, supplied by American Buildings Company, is designed to support extra load for solar panels.
A new corridor, conference room and entrance area were all constructed of bar joists and metal decking. The steel was set so that a concrete floor slab can be poured at a future date if a second floor is needed in this area. This flat roof area is covered with a 15-year white TPO membrane, mechanically fastened to the roof and parapet walls over 2.5" minimum tapered insulation, and internal roof drains.
Wood parapet trusses, designed to look similar to the existing building - covered with cedar wood roof shakes, cedar soffit and copings - were installed along the upper edges of the building’s new flat roof. This detail is also used on the top of the west and south high walls of the gym. A total of 1,112 sq. ft. of unfinished wood mezzanine areas were included to add floor space designed to support light storage and the HVAC equipment.
The new building blends in architecturally with the existing school. The west wall and about a third of the south wall has full height block, 1” insulation, and a brick veneer with colors and patterns to closely match the existing building. The north wall of the building has full-height, core insulated, standard concrete block with textured, water-resistive paint. The first 24' of east side wall is full height masonry block with 1" insulation and brick veneer. The balance of the east side high wall and the remaining two-thirds of the south wall are full-height, heavy gauge metal stud and DensGlass sheathing designed to accept a brick support angle and brick veneer on the upper 9'. The south exterior, upper wall is finished from the lower roof level up to the underside of the soffit with brick veneer supported by a brick support angle installed during phase one. The back side of the wood truss parapets in the area between buildings, greater than 4' has plywood sheathing and a cedar siding finish. The east side wall is temporarily covered with vinyl siding in preparation for removal during Phase II. The low south wall is block with a brick veneer to the gutter line.
