J UNE 2017 | 19 Roofing/Cladding Materials as technologically advanced elastomeric modified asphalt. Also, Building Products' Weather-Tite shingle meets and exceeds the Underwriter's Laboratory highest Class 4 rating for impact resistance, making it one of the most durable shingles on the market – providing superior protection against wind, rain, snow and hail. It's worth noting that no product advancement would be possible without plenty of research and development, and in this regard the Roofing Contractors Association of British Columbia (RCABC) not only exists to ensure that roofs are installed cor- rectly, it also takes an active role in advancing roofing technology via several ave- nues (for example, its RCABC training centre is the first educational facility in North America designed for and dedicated to training the entire roofing industry). RCABC is also currently involved in several research projects this year, according to Hamish Matheson, the association's RoofStar technical advisor. "We're taking a look at low slope membrane roofs in older houses to determine the impact of block- ing off the vent air cavity and insulating above that in re-roofing projects," he says. "We're also field studying the different effectiveness of membrane colours, and as is the case with our other studies, the outcomes of these projects will be published online, for the benefit of people in the trade." Yet another RCABC undertaking, in collaboration with the National Research Council Canada, is the true R value of different commercial roof systems at differ- ent temperatures. "Even though a roof is designed for a particular R value, it doesn't necessarily translate to that value in the field, so we're looking at everything from attachments to insulation, to determine what influences the values and why," says Matheson. Last but hardly least, steel is often chosen as the ideal type of material not only for roofing but the entire building envelope, and the frameless steel buildings such as those manufactured by Behlen (with their renowned engineered panel systems) guarantee minimal maintenance while maximizing versatility and visual appeal. Behlen's roof systems consist of corrugated roof and ceiling panels, joined by a lightweight, bolt-together truss; they provide a ventilated attic that lowers energy cost and eliminates the potential for wet insulation caused by condensation or leaks in light gauge roof cladding found in other building systems. This April, Behlen announced the signing of a $45-million contract that Sean Lepper, VP and general manager, describes as "the biggest contract in our history and a unique deal for us where we have committed to manufacture and build sports complexes in Georgia. Winning this contract means more work for Behlen employ- ees and more jobs in our community.'' The contract consists of three indoor arenas capable of hosting various sport- ing events; a larger hall will be able to host 3,500 spectators while two smaller ones will have a capacity of 2,500 people. These new sporting facilities are going to be located in Batumi, Telavi and Gori, Batumi being a resort city and major tourist hub on the Black Sea coast.
