Westcor Thermal FAQ – Insulation & Fireproofing in Metro Vancouver
For builders, property managers, and contractors across the Lower Mainland.
What services does Westcor Thermal provide in the Lower Mainland?
We specialize in spray foam insulation, fireproofing (mineral fibre, intumescent, cementitious), firestopping, CrossRock PG parkade insulation, CAFCO systems, acoustic spray, and batt insulation for commercial, industrial, and multi-unit residential projects.
Why is spray foam insulation popular for commercial projects?
Spray polyurethane foam creates a continuous air & vapour barrier, reduces thermal bridging, and offers high R-value per inch—ideal for warehouses, office towers, and retrofits.
Is spray foam suitable for retrofit projects in Vancouver?
Yes—it’s commonly used in retrofits and tenant improvements to improve airtightness, comfort, and energy performance without major demolition.
How does CAFCO fireproofing protect commercial buildings?
CAFCO spray-applied fireproofing insulates steel and concrete, slowing heat rise and helping assemblies meet required fire-resistance ratings.
What’s the difference between intumescent and mineral fibre fireproofing?
Intumescent expands in heat to protect exposed steel while preserving a clean aesthetic; mineral fibre uses rock-wool fibres with a cement binder for robust coverage over beams, decks, and wall assemblies.
Why is fireproofing critical for Metro Vancouver high-rises?
Fireproofing maintains structural stability in emergencies and ensures compliance with Vancouver’s building and fire codes on high-rise and mixed-use projects.
What is CrossRock PG and why use it in parkades?
CrossRock PG is stone wool with long-term R-value, sound absorption, non-combustibility, and water repellency. Its reflective facer brightens garages, often reducing lighting requirements and electricity costs.
Do you install acoustic spray insulation in Metro Vancouver?
Yes—SonaSpray and K-13 reduce reverberation in schools, churches, theatres, offices, and arenas for better clarity and comfort.
Is batt insulation still relevant for large buildings?
Yes—rockwool and fiberglass batts remain cost-effective for walls, ceilings, and attics in multi-unit and light commercial projects; pair with spray foam for superior airtightness.
How do you ensure safety during spray foam and fireproofing installs?
We follow strict WorkSafe BC protocols with PPE (respiratory protection, Tyvek suits, fall protection) and coordinate site safety with GCs and trades.
What areas of Metro Vancouver does Westcor Thermal serve?
We serve Vancouver, Surrey, Burnaby, Richmond, Delta, Langley, Coquitlam, New Westminster, White Rock, and the Fraser Valley. Projects of any size.
Is spray foam better than fiberglass insulation?
Often, yes. Spray foam seals gaps and creates an air & vapour barrier with higher R-value, delivering superior energy savings vs. fiberglass batts.
How long does spray foam insulation last?
Properly installed spray foam can last 30+ years without sagging or settling, maintaining performance over time.
What is the fire rating of mineral fibre spray?
Depending on assembly and thickness, mineral fibre spray can achieve 1–4 hours of fire resistance.
Is CrossRock PG waterproof?
Water-repellent, not waterproof—resists moisture while remaining vapour permeable, which is ideal for parkades.
