Our Services
We Offer a Range of Insulation Solutions to Meet Your Needs
From new construction to home upgrades and commercial retrofits, Thermax Insulators brings certified expertise and top-of-the-line products to every project. Serving the Pacific Northwest — including Smithers, Terrace, Kitimat, Prince Rupert, Haida Gwaii, Burns Lake, and surrounding communities
Spray Foam Insulation
Spray foam is the gold standard in modern insulation — and Thermax is your certified source for it across the Pacific Northwest. We use BASF Walltite ECO 2lb Closed Cell Spray Foam, an exclusive product that delivers exceptional thermal performance and creates a completely airtight seal without the need for a separate vapour barrier.
Best for: Concrete walls · Crawlspaces · Metal buildings · C-cans & quonset huts · Floor systems · Box joists · Under-slab applications · Residential & commercial new builds or retrofits.
Key benefits:
• Superior thermal performance compared to conventional batt insulation
• Creates an airtight seal that stops drafts and reduces heat loss
• Moisture-resistant — no vapour barrier needed
• Adheres to wood, steel, concrete, and aluminum
Machine-Blown Attic Insulation
Attic insulation is one of the most cost-effective upgrades any homeowner or building owner can make — and Thermax makes the process fast, clean, and hassle-free. Using machine-blown technology with premium products like Johns Manville Fiberglass and Weathershield Cellulose, we achieve complete, even coverage from R28 to R80.
Best for: Residential attics · Commercial building upgrades · New construction.
Key benefits:
• Fast installation with thorough, consistent coverage
• Safer and more affordable than manually placed batt insulation
• Available in a range from R28 to R80 to meet your energy needs
• Johns Manville Fiberglass and Weathershield Cellulose options available
Silicone Roof Coatings
Extend the life of your roof without the cost and disruption of a full replacement. Thermax applies premium silicone roof coatings — including Momentive and BASF Skytite — over existing metal roofs and torch-on membranes, creating a seamless, waterproof barrier that reflects heat and resists UV degradation.
Best for: Metal roofs · Existing torch-on membranes · Commercial and industrial buildings.
Key benefits:
• Seals leaks and prevents future moisture intrusion
• Reflects heat, improving energy efficiency
• Extends roof life at a fraction of replacement cost
• Applied directly over existing roofing — no tear-off required
Thermal Protection
In addition to insulation, Thermax applies protective thermal coatings over spray foam surfaces to enhance durability and UV resistance. This finishing step is especially important for exposed foam in commercial and industrial settings, ensuring your investment performs and lasts for years.
Free Insulation Inspections
Not sure what your building needs? Thermax offers free, no-obligation insulation inspections for homeowners and business owners across the Pacific Northwest. Our certified specialist will assess your current insulation, identify gaps or problem areas, and give you an honest, straight-talking recommendation — no upselling, no pressure.
This is the Thermax difference: we'd rather give you good advice than sell you something you don't need.
Metal Building & Industrial Insulation
Metal buildings present unique insulation challenges — condensation, temperature swings, and energy loss. Thermax has extensive experience insulating metal structures of all types, using closed-cell spray foam that adheres directly to metal surfaces, eliminates condensation risk, and delivers immediate improvements in thermal comfort and energy efficiency.
Applications include: Metal shops · Warehouses · Agricultural buildings · Industrial facilities · C-cans · Quonset huts
New Construction Insulation Packages
Building new? Thermax works with contractors, developers, and owner-builders throughout the Pacific Northwest to provide complete insulation packages for new residential and commercial construction. We coordinate around your build schedule and ensure your project meets or exceeds BC energy code requirements
