Open and closed-cell polyurethane spray foam for maximum R-value and air sealing.
Our spray foam insulation expands to fill every cavity, creating a continuous air and vapour barrier that drastically reduces energy loss. We install both open-cell (½ lb) and closed-cell (2 lb) systems for walls, attics, basements, rim joists, and crawl spaces across the GTA.
