16 ROOFING CANADA FALL/WINTER 2018 2018 ROOFING CANADA AWARD Bothwell Accurate’s in-house team was then tasked with delivering the roof. It installed the sheathing board and 2-ply modified bituminous roof while RTC designed and manufactured the light- gauge framing required to install Kalzip's curved standing seam metal roof over the 2-ply system. The RTC system began with a hat channel framing component (aka furring channel) fastened to the superstructure through the 2-ply roof. Clip angles were then used to achieve height separation and support for the pre-curved track and stud assemblies to which the Kalzip standing seam metal roof clips were attached. Bothwell Accurate also worked with Soprema to develop a warranty- approved method to seal the required hat-channel fastener penetrations. Roxul mineral wool insulation was used to cover the 2-ply modified bit roof, and the high emissivity value of the Kalzip standing seam worked to reduce the overall solar gain of the building’s roof. “This inverted approach and the high emissivity value guarantees the 2-ply system never experiences thermal or UV degradation,” says McGrath. Collective expertise Ultimately, the success of the project came down to the collaboration of all the partners and their collective expertise. Not only did RTC and Kalzip coordinate their 3D fabrication models to assure both their systems would fit together, but the firms worked in unison to maintain a smooth schedule. “Kalzip fabricated the pre-curved roof panels while BA installed the pre-curved framing,” recalls McGrath. “The first shipment of RTC light-gauge framing arrived on site at a predetermined pace that allowed BA to continuously install framing without any stops. Immediately following framing completion, the pre- curved metal roof panels arrived, and proceeded continuously according to the contract schedule.” It also helped a lot, continues McGrath, that the entire team was in communication throughout the project to address any site issues as well as requests coming from the transit authority. “It couldn't have been done without this team,” he stresses. “The L’équipe de Bothwell avec son prix Couvertures Canada The Bothwell team with its 2018 Roofing Canada Award
