Spray polyurethane
The highest-performing insulation on the market.
Spray polyurethane foam is a revolutionary insulating material. Applied as a liquid foam, it expands instantly to seal every crack and cavity, creating a thermal and air-tight barrier with no seams or thermal bridges.
Almost twice as insulating as batts
At equal thickness, spray foam insulates almost twice as well as traditional batt insulation. And unlike batts, it also stops air and moisture.
Perfect air seal
Stops air, moisture and infiltration in a single application. Eliminates thermal bridges.
Custom application
Adapts to any shape, from walls to cathedral ceilings. See our most requested work.

What people ask us most often.
Can you insulate in winter?
Yes. Interior work such as rim joists, basements and crawl spaces is done all year round. The product and equipment are kept at the right temperature.
How long does a project take?
Most residential projects are completed in one day or less.
How do I prepare?
Clear access to the surfaces to be insulated, about one metre around them, and remove or cover anything nearby. Thermik sends you a preparation sheet before the work.
Do I need to cover the spray foam?
In a living space, the Building Code requires a thermal barrier, such as drywall. Thermik tells you what applies to your project.
What warranty do I get?
The Zero Risk Guarantee covers the fixed quote, the thermal proof, the comfort guarantee and a single point of contact from start to finish. The foam is also covered by the manufacturer's warranty.
Am I eligible for a grant?
Some programs such as Rénoclimat and LogisVert may apply. Conditions change and an evaluation before the work is often required. Thermik prepares the technical documentation for your file.
Do you need to visit to give me a price?
Not always. For simple projects like rim joists, a few photos and measurements are often enough for a written quote without a visit.
