The company ceased manufacturing of all products containing HFCs as of January this year, in preparation to meet full compliance under the Department of Environment and Climate Change of Canada. "We replaced the blowing agent with hydrofluoroolefin, which caters to builders, contractors, architects, engineers, and homeowners who want premium insu- lating products with lower impact to the environment," Duzyk says. Huntsman is well known for its Heatlok Soya closed-cell spray foam, designed as a continuous insulation solution contributing to air, heat, water, and vapour protection with superior adhesion. "This is really one product whose single application provides insulation, an air barrier, and a vapour barrier, plus a high R-value of R-6 per inch," Duzyk says, adding that the foam is sprayed from the exterior with no surface preparation needed, no seams to seal, and no boards to glue in place. Heatlok Soya expands 30 times its initial volume in five seconds and seals the entire foundation (it also does not absorb water over time, which makes it an ideal below grade foam). Plus, studies have shown that a wall assem- bly with only Heatlok HFO reduces HVAC loads and lowers building operational carbon emissions. One of Huntsman's most innovative new products related to insulation is the D-Max Wall assembly, which allows the Heatlok Soya HFO spray foam to be installed completely from the interior and cuts the thermal bridge of the studs by filling the gap between the exterior sheathing panel (exterior gypsum) and the studs. Z-bars are installed directly on the exterior face of the studs before the sheathing is installed (the spacing and size of the Z-bars vary depending on the type of building and cladding). Duzyk says, "The D-Max wall allows a high performance assembly for effective thermal resistance and airtightness with very thin walls. Construction is very fast and safer, which in turn reduces construction costs and speeds building delivery." Yet another insulation-related benefit of Heatlok Soya is that it is 65 times more resistant to radon gas than a six millimetre polyethylene membrane. Spraying the foam on the substrate before the basement floor is poured is an excellent protection against radon, which is Canada's second most common source of lung cancer. Soprema offers insulation products with extraordinary properties and benefits synonymous with quality, durability and efficiency, plus the company supports these offerings with consultation services to contractors, as required, for their construction projects. Some product examples include 3-1 Soprasmart ISO HD, a factory-laminated high-performance insulating base sheet panel composed of SBS modified bitu- men membrane, high-density polyisocyanurate insulation support panel, and a polyisocyanurate insulation board. This fast and easy to install product is excel- lent for work sites with reduced labour or for projects with a very large area. Heatlok Soya HFO spray foam insulation.
