Modern spray foam insulation products used by professional contractors in Langley BC have improved significantly in their environmental profile. Low-global-warming-potential blowing agents are now standard in professional-grade closed-cell products, replacing the high-GWP HFC compounds used in older formulations. Once fully cured, spray foam is chemically inert, does not off-gas, and does not release particulates into indoor air. Its decades-long service life also means it does not require the replacement cycles that contribute to landfill waste. Western Insulation uses low-GWP formulations on every Langley spray foam project. Visit westerninsulation.ca/spray-foam-insulation/
