Key to securing this designation is the use of materials upholding the highest standards of sustainable construction, and on that score Westcor Thermal Inc., the spray foam installation contractor for the project, selected Huntsman's Heatlok Soya HFO (a spray foam with a Global Warming Potential of 1, which is 99.9 percent lower than traditional blowing agents) over alternatives such as fibreglass and mineral wool. Westcor president Marcus Hamm says, "We recognized early on that for The Stack to truly stand out and meet our sustainability goals, Heatlok Soya HFO was the product to spec," and he adds that Huntsman's "readiness to provide techni- cal support made the decision straightforward." Heatlok Soya HFO played a pivotal role in The Stack, providing consistent thermal insulation, acting as an air and moisture barrier, and seamlessly integrating with the building's diverse architectural elements, with its inherent flexibility ensuring that the distinctive design remained intact. Finally, Johns Manville, a Berkshire Hathaway company, is a leading manu- facturer and marketer of premium-quality building and specialty products with 44 manufacturing facilities in North America and Europe. Earlier this year it announced the release of a new High Yield Open-Cell (HYOC) spray foam, which in conjunction with JM's line of spray foam products, gives installers an even broader range of choices. HYOC SPF is designed for interior commercial, residential, and industrial applications, and it distinguishes itself by enabling installers to achieve exceptional yields: 20,000 average BFT sprayed on a clean, dry, sound OSB substrate at 75°F. Like other Corbond SPF products, HYOC has low odour and superior sprayability. Johns Manville's complete line of SPF products provides superior thermal energy efficiency, as well as advanced air and sound control. JM Corbond open cell SPF insulation covers gaps and voids to virtually eliminate air leakage, and it can exceed the performance of traditional fibreglass insulation. With the intro- duction of HYOC SPF, "This positions JM as a fully competitive manufacturer in the spray foam market," according to Tom Calzavara, JM senior manager, SPF and technical services.
