Frequently Asked Questions about Cork Insulation

Where can I buy expanded cork insulation in Vancouver? Casa Veda Imports is the premier local supplier of expanded cork insulation for Vancouver, Squamish, Whistler, and the broader BC region. We manage the direct import logistics from Portugal so you can source locally.

What is the R-value of expanded corkboard? Expanded cork provides a stable thermal resistance of approximately R-3.6 to R-4.0 per inch, depending on the specific density. Crucially, it does not suffer from thermal drift, meaning it retains this R-value for decades.

Is cork insulation waterproof? Expanded cork is highly water-resistant and dimensionally stable due to its natural suberin content. While it is not a waterproofing membrane, it manages bulk water exceptionally well and is vapor-permeable, allowing wet assemblies to dry safely.

Is cork insulation fire-rated? Yes. Our expanded cork achieves a Class E fire reaction rating (exposed) and a B-s1, d0 rating in ETICS systems. It chars naturally in the event of a fire without melting, dripping, or releasing toxic chemical smoke like standard plastic foams.
