Spray Foam Insulation in Coastal BC: Is It Worth It for Your Home?

For homeowners on Vancouver Island and the Gulf Islands, spray foam insulation in coastal BC offers protection from the region’s wet, windy, and salty climate. Living by the ocean has its benefits—but it also brings unique insulation challenges.

Traditional insulation materials often fall short in coastal BC. If you’re tired of battling cold drafts in the winter, excess humidity in the summer, or mold concerns year-round, it might be time to consider an upgrade.
