Spray Foam Insulation in Vancouver — Residential & Commercial
westcorthermal > Services > Spray Foam Vancouver
Westcor Thermal is a CUFCA-certified spray foam insulation contractor serving Vancouver, Burnaby, Surrey, Richmond, and the entire Lower Mainland. Since 2001, we have been installing open-cell and closed-cell spray polyurethane foam for residential and commercial properties — from single-family homes and crawl spaces to large-scale commercial and industrial buildings across BC, Alberta, and the Northwest Territories.
Vancouver's wet coastal climate makes proper insulation critical. Spray foam insulation creates a continuous air and vapour barrier that outperforms traditional fiberglass or cellulose — sealing every crack, preventing moisture intrusion, and delivering R-values of up to R-7 per inch with closed-cell foam. Whether you are building new or retrofitting an existing structure, our certified applicators get it right the first time.

Open-Cell vs Closed-Cell Spray Foam — Which Is Right for You?
Spray foam insulation comes in two types. Choosing the right one depends on your application, budget, and performance requirements.
Closed-Cell Spray Foam (2 lb)
• R-6 to R-7 per inch — the highest R-value of any spray foam product
• Acts as both an air barrier and a vapour/moisture barrier
• Rigid and adds structural strength to walls and roofs
• Ideal for: exterior walls, crawl spaces, basements, parkade ceilings, and moisture-exposed areas
• Most commonly specified on commercial and industrial projects in Vancouver
Open-Cell Spray Foam (½ lb)
• R-3.5 to R-4 per inch — expands to fill large cavities
• Soft, flexible foam that accommodates building movement
• Outstanding sound attenuation — ideal for acoustic applications
• Ideal for: interior walls, attics, rental suites, and residential applications where soundproofing matters
• Budget-friendly option for large-area residential projects
Our CUFCA-certified installers will assess your project and recommend the right foam type — or a combination of both — to meet your specific needs and BC Building Code requirements.
Benefits of Spray Foam Insulation for Vancouver Homes & Businesses
Vancouver's climate demands more from insulation than most Canadian cities. Here is what spray foam insulation delivers:
🌡️ Energy Efficiency & Cost Savings
Spray foam creates an airtight seal that prevents heat loss in winter and keeps your building cooler in summer. Properly insulated Vancouver homes can see up to 40-50% improvement in energy efficiency. That translates directly to lower utility bills year after year.
💧 Moisture & Mould Control
Vancouver averages over 1,150 mm of rainfall per year. Closed-cell spray foam acts as a Class II vapour retarder, blocking moisture intrusion that leads to mould growth, rot, and structural damage — critical protection for crawl spaces, basements, and exterior walls.
🔇 Soundproofing & Noise Reduction
Open-cell spray foam significantly reduces airborne noise transmission between rooms and from outside. It is an ideal solution for secondary suites, home offices, music rooms, and properties near busy roads in Metro Vancouver.
🏗️ Structural Strength
Closed-cell spray foam bonds rigidly to surfaces, reinforcing wall and roof assemblies. Studies show it can increase racking strength in wood-frame construction — a meaningful benefit in BC's seismic zone.
🌿 Eco-Friendly & Sustainable
We use Demilec spray foam — a soy-based, eco-friendly product rather than a petroleum-based alternative. It uses less energy to manufacture than fibreglass and contributes to a smaller carbon footprint throughout the building's lifetime.
Spray Foam Insulation Applications in Vancouver
Our certified spray foam teams work across all building types and areas:
Residential Applications

How Spray Foam Insulation Works
Spray foam is a two-component system manufactured on site. The two chemicals — polyol resin and isocyanate — are heated and pumped through a proportioner to a mixing gun, where they combine and are sprayed through pressurized nozzles. The reaction is instantaneous: the foam expands immediately on contact, filling every gap, crack, and void.
Our Vancouver spray foam applicators control depth and coverage precisely, building up the required insulation thickness in multiple passes. The result is a seamless, airtight, waterproof insulation barrier that outperforms any batt or blown-in product.
From the moment spray foam is applied, it begins to cure. Within seconds, the foam is tack-free. Within 24 hours, it reaches full cure — ready for your building to be occupied, drywalled, or painted over.
Frequently Asked Questions — Spray Foam Insulation in Vancouver
Q: What is spray foam insulation and why is it ideal for Vancouver homes?
Spray foam insulation is a two-component polyurethane system that expands on application to create a continuous, airtight insulation barrier. For Vancouver properties, it is ideal because it simultaneously insulates, air-seals, and acts as a vapour retarder — critical protection against the city's persistent dampness and rainfall. It outperforms fibreglass or cellulose insulation in all three functions.
Q: What is the difference between open-cell and closed-cell spray foam?
Closed-cell foam (2 lb density) is rigid, delivers R-6 to R-7 per inch, and acts as a vapour and moisture barrier — best for exterior applications, crawl spaces, and commercial projects. Open-cell foam (½ lb density) is softer, delivers R-3.5 to R-4 per inch, and provides excellent soundproofing — ideal for interior walls and attics. Our team will recommend the right product or combination for your project.
Q: How much does spray foam insulation cost in Vancouver?
Spray foam insulation in Vancouver typically ranges from $1.50 to $5.00 per square foot depending on the foam type, application area, and project size. After accounting for government rebates — which can reach $5,500 through CleanBC — the net cost is often much lower. Contact Westcor Thermal for a free, itemised quote for your specific project.
Q: Can spray foam insulation help qualify for government rebates in BC?
Yes. Spray foam is an eligible insulation type under the CleanBC Better Homes Program (up to $5,500) and the Canada Greener Homes Grant (up to $5,600 federal). These programs can be stacked for qualifying projects, significantly reducing your net investment. Work must be completed by a registered contractor — Westcor Thermal can advise on eligibility for your project.
Q: Is spray foam insulation safe for residential properties in Vancouver?
Yes. Once cured, spray foam is inert, non-toxic, and safe for occupied buildings. All of our installers are CUFCA-certified and trained in safe application practices. We use PPE and follow all WorkSafeBC and BC Building Code requirements on every project. Temporary ventilation protocols are followed during installation.
Q: How long does spray foam insulation last?
Spray foam insulation, when properly installed, does not sag, compress, or degrade over time. It can last the lifetime of the building — typically 30 years or more — without any performance loss. This makes it a superior long-term investment compared to fibreglass batt, which can sag and lose R-value over time.
Q: When is the best time to install spray foam in Vancouver?
Spray foam can be installed year-round in Vancouver. Spring and fall offer optimal ambient temperatures for the fastest curing times, but modern spray foam systems are formulated to perform in a wide range of conditions. Our team schedules installations efficiently regardless of season — contact us to book your project.
Q: Do I need to leave my home during spray foam installation?
Occupants should vacate the treated areas during application and for a period after, typically 24 hours, to allow proper curing and off-gassing. Your Westcor Thermal project manager will provide specific guidance based on the size of the area being treated and the products being used.
