The bottom clip catches the edge of the panel so that the dead load is taken by the mechanical system, and the wind load is taken by the adhesive system, meaning no mechani- cal fasteners and proper expansion/contraction. This provides confidence in longevity, durability, and sustainability. The 35 Park West project is relatively close to another notable Engineered Assemblies project, the redevelopment of the 10-acre, 88-year-old Shannon estate, once home to sugar magnate B.T. Rogers. For this multi-residential development by Wall Financial and designed by Perkins + Will, Equitone Tectiva was used extensively as was 60,000 square feet of Eternit supported by the EA thermally broken TcLip. "We used Glasal Equitone Tectiva fibre cement panels with face fastened rivets, and engineering assistance was given to allow spans to go beyond 48 inches vertically to 55 inches," says Smith. "Shannon was a real showcase project for us, with the wall assemblies contributing to a superior thermal performance." Finally, resiliency is practically a byword of Tech-Crete Processors' composite insulating panels, and it has been estimated that about 20-million square feet of the com- pany's Concrete Topped Insulated (CTI) and Solar Reflective Insulated (SRI) roof panels in the Canadian marketplace, along with two-million square feet of Concrete Faced Insulated (CFI) wall panels. Tech-Crete's SRI roof panels, such as those used in the LEED Silver Edmonton Clinic Health Academy, are self- ballasted, solar reflecting insulating panels designed for use in a Protected Membrane Roof assembly. The factory-applied white concrete coating gives SRI panels superior insulations, long-term durability, membrane protection, and solar reflectivity in one step. Specifically, the solid 3∕8-inch thick white concrete means there is no coating to maintain or reapply; it can be rinsed or pressure washed without risk of mem- brane damage and even withstand occasional roof maintenance foot traffic. As for proof of the durability of Tech-Crete roofing products overall, the Kinesiology building at the University of Calgary is a good example. CTI roof panels (self-ballasted insulated panels consisting of a durable concrete topping on a panel of highly-efficient Styrofoam brand foam insulation) were originally installed on the facility in 1986, and 25 years later a significant portion of them were removed to allow work crews access to underlying components – and then re-installed for insulation, ballast, and protection as originally intended. As for the CFI wall panels, they are pre-finished exterior insulating panels designed for use in perimeter foundation and low-rise wall installation. Easily installed with patented galvanized steel mounting clips, the panels are ideal for new or retrofit exterior applications over block or cast-in-place masonry, and can be field coated with any quality masonry coating to match existing colour (or to upgrade building exterior).
