OCTOBER 2019 | 17 Insulation PHOTOGRAPHY COURTESY ICYNENE-LAPOLLA shell wall panels that incorporate a layer of rigid insulation between the exterior wythe of concrete and the back-up system reduce the weight of the pan- els relative to other precast wall systems. Some can also be designed as load bearing." One of the ways Icynene-Lapolla sets itself apart from other manufacturers is the credentialing it has for its products. With the rollout of HFC blow- ing agents in SPF, manufacturers must have an HFO product in order to meet building code standards and supply contractors in Canada; Icynene-Lapolla will have two HFO products for both its Icynene and Lapolla brands. Additionally, the company's new Icynene Proseal HFO has many benefits for end users: the closed-cell product provides a very low global warming poten- tial (a GWP of only one) and yet is extremely high performing, giving work crews the ability to spray up to an incredible 5.5-inches in a single pass (with a one hour re-entry and two-hour re-occupancy). It also achieves an R-value of R-6.8 per inch at 3.5 inches and meets FEMA flood requirements. "We have seen a growing demand for spray foam in the agricultural sector for insulation in metal buildings and other farm infrastructure. A couple of the more recent jobs were an apple orchard, and processing plant, and another was a potato farm in Alliston, Ontario," says Doug Kramer, president and CEO for Icynene-Lapolla. Other projects that Icynene-Lapolla has worked on include a custom house in Hamilton that is made out of shipping containers and features Icynene ProSeal on the inside walls. Companies associated with spray foam insula- tion are well aware of the ever-changing regulatory landscape in Canada. Specifically, spray-applied poly- urethane foam currently has a higher global warming potential than other insulation materials, and new regulations will require all manufacturers to change their blowing agent so that their final product reaches carbon neutrality as much as possible. The goal is that by January 1, 2021, spray-applied poly- urethane foam will have a GWP almost identical to other insulation technologies like cellulose and fibre- glass, which have a GWP of zero. Andrew Cole, executive director of the Canadian Urethane Foam Contractors Association (CUFCA), says, "The spray foam industry is positioning itself for resiliency, not just R values. One of our goals as an association is to focus on the many benefits of closed cell spray foam in 2021 and beyond, especially with regard to the increasing incidences of severe weather in Canada."
