FEBRUARY 2015 | 43 PHOTOGRAPHY COURTESY MAXXON CORPORATION & ARRISCRAFT INTERNATIONAL Restoration Products & Services and ask us to provide a replica to the natural stone used on their historic buildings. The products we use depend on what's there on the campus," says Jason Nieman, director of quality and development at Arriscraft International. The company's Arriscraft Renaissance product lines are being used for such restoration projects. One of them is the ARRIS clip system. Its Thin-Clad units are simply clipped onto a substrate using a pre-engineered channel system and enable scheduling flexibility as they have been installed sequentially. "The clip can be used for new buildings or retrofits. It's a whole system and includes stone and a channel system for anchoring the stone. Installation is very quick," Nieman says. A special aspect of Arriscraft's masonry products for cladding is that no product is made from concrete. "All are based on calcium silicate. We take sand and lime, and compress and cure it in an autoclave," Nieman says. When it comes to a restoration project that includes a windows and glazing ret- rofit, some products from Zola European Windows could well be an option. The company mostly specializes in high-end fenestration and doors, and includes a line of windows designed for Passive House applications. Lately, though, the firm has been supplying its own version of sliding double-hung windows for retrofit projects on New York brownstones. But sliding windows tend to have poor thermal performance, so Zola's American Heritage SDH, which is described as "a replica quality tribute to the historic double- hung window," comes with a progressive twist. "Ours don't slide. The bottom tilts and turns, and the top is fixed. But the look is 100 per cent there," says Florian Speier, a founder and VP at Zola. Restoration is also a significant part of the business at Maxxon Corporation, says Dave Nicholson, the company's international technical manager. He observes, though, that the cyclical nature of the business tends to seesaw the emphasis back and forth between new construction and retrofits. "Malls are constantly refurbish- ing and redesigning. We're more into sound control and self-levelling. Even with- out sound control, the underlayment systems themselves help attenuate sound," Nicholson says. Products like Maxxon's Dura Cap, he says, can be used on retrofits where the concrete sags or falls away between columns. For Icynene Inc., a supplier of closed and open cell foam insulation, new home sales remain the lion's share of its market. Still, says John Evans, the codes and stan- dards manager at Icynene, "We see growth potential for retrofits."
