Spray foam is not the right choice for every application in a Langley home — but where it is correct, nothing else comes close. Closed-cell spray foam is clearly the best choice for crawlspace walls, rim joists, basement foundation walls, cathedral ceiling assemblies, and unvented roof designs. In each of these locations its combination of high R-value per inch, complete air sealing, and simultaneous vapour control solves multiple problems in one application. Western Insulation identifies the specific zones in your Langley home where spray foam is genuinely correct — and where blown-in or batt is more cost-effective.
