Basement & Crawl Space Insulation

Below-grade insulation for basements and crawl spaces addresses one of the most persistent comfort and energy challenges in New Brunswick homes, where uninsulated foundation walls and rim joists account for 20-30% of total heat loss and create cold, damp conditions that promote mould growth and structural deterioration.

New Brunswick's high water tables and Maritime humidity make moisture management inseparable from basement insulation — spray foam applied directly to concrete foundation walls and rim joists creates both a thermal barrier and a vapour barrier in a single application, eliminating the condensation that forms when warm interior air contacts cold concrete.

For NB crawl spaces, encapsulation with closed-cell spray foam on walls and a sealed vapour barrier on the floor transforms a damp, energy-draining void into a dry, conditioned space that improves comfort on the floor above.
