The highest-performance insulation on the market. Open-cell and closed-cell spray foam delivers R-values up to R-6.5 per inch, while sealing every crack and blocking moisture.
Spray foam insulation has fundamentally changed how homes and buildings stay warm. Unlike traditional batts, spray foam expands on contact to fill every gap, crack, and irregular cavity — creating a continuous air barrier that batts physically cannot match.
Properly installed spray foam lasts the lifetime of the building — typically 80+ years. It does not settle, sag, or lose R-value over time.
Once cured (within 24 hours), spray foam is inert and safe. Bestway uses only certified low-VOC formulations and ventilates work areas during installation.
Yes — when properly installed in the attic, closed-cell spray foam is one of the most effective solutions for preventing ice dams.
Ontario Building Code requires R-22 walls and R-60 attics minimum. Closed-cell at 3.5 inches achieves R-22.5 in walls; open-cell at ~16 inches achieves R-60 in attics.
From Toronto and the GTA to Muskoka, Sudbury, and beyond.
Spray foam is applied as a liquid that expands on contact, sealing every gap, crack and penetration in a single pass — something batt and blown-in simply cannot do. Bestway installs two types: open-cell (about R-3.6 per inch, lightweight, great for interior walls and sound-dampening) and closed-cell (about R-6 per inch, rigid, water-resistant, and a vapour barrier in its own right).
Closed-cell is our go-to for basements, rim joists, crawl spaces and additions where moisture control matters; open-cell shines in attics and wall cavities where you want maximum R-value per dollar. Because foam air-seals as it insulates, it also eliminates the drafts and ice-damming that fibre insulation leaves behind.
