Thermal insulation

We offer you innovative insulation solutions so that the interior of a building is comfortable at all times and that you can reach the highest performance standards in terms of energy efficiency.

Vapor barrier and air barrier

After analyzing the building’s characteristics, we recommend the best products to effectively control the passage of air and humidity.

Mechanical insulation

The high energy efficiency resulting from the judicious choice of insulation materials and methods has enabled Mongrain to become a leader in insulation in Northern Quebec, where the presence of strong winds always represents a challenge for the buildings’ airtightness.

Our insulation team’s vast knowledge is put to good use in every project we carry out and the best products (polyurethane, cellulose, etc.) are used.
