Closed-cell spray foam is the highest-performing crawlspace insulation material available for Langley homes — and the reasons are clear. It delivers R-6 to R-7 per inch of thermal resistance, creates a complete air and vapour barrier in a single application, and does not absorb moisture or support mold growth. Western Insulation applies spray foam directly to crawlspace walls and rim joists across Langley, sealing every gap before moisture and cold air have a chance to cause damage. Combined with a heavy-duty polyethylene vapour barrier across the crawlspace floor, it is the most complete and long-lasting solution available for Fraser Valley homes. BC rebates may apply.
