Cold Climate

Located in Sainte-Adèle, Québec, this cold-climate home demonstrates how a high-performance building envelope can deliver long-term energy savings, comfort, and durability. By choosing Heatlok® Soya closed cell spray foam for the roof, walls, and slab, the owners—one with a background in architecture—adapted the D-Max commercial wall assembly concept for residential use. The result is a home that is nearly four times more airtight than code-built houses, consumes 43% less energy, and provides protection against radon, air leakage, and future energy cost increases—all while enhancing design, comfort, and resale value.
