Cellulose Insulation

Insufflation d'isolant de cellulose Beno-Therm au grenier.

Beno-Therm cellulose insulation blowing in attic.

The blown thermal and acoustical cellulose is a great choice for the insulation of the roof and walls in new construction projects or during renovations.

The Beno-Therm insulation is manufactured by Benolec. It is made of recycled paper fibers. Minerals are also included in the cellulose insulation composition to insure its fire and mold resistance.

Beno-Therm thermal and acoustical cellulose insulation reduces air leakage by reaching the smallest interspaces producing a homogeneous cushion without joints (thermal bridges) in the attic and in the walls.

For the attic thermal insulation, you will need Beno-Vent aeration vents.

Wall Insulation

The small size of the cellulose insulation fibers makes it a good product for the wall injection with the Beno-Mat technique as well as in the attics. When injected with a density of 3.0 pounds/cubic foot in the wall cavities, the cellulose insulation gets the walls more airtight.

Volatile Organic Compounds (VOCs)

Beno-Therm is tested in accordance with UL 2821 test method to show compliance to emission limits on UL 2818-Section 7.1 and 7.2.

Beno-Therm cellulose insulation in attic.

The Beno-Therm thermal and acoustical insulation offers one of the highest thermal performances on the market with an output of 3.76R/inch of thickness and a density of 1.6 pound per cubic foot. The Canadian Model National Code of Energy for habitation recommends R-40 to R-50 in the attics depending on the region, witch represents a thickness of 10.8 to 13.5 inches of Beno-Therm cellulose insulation once crammed.

Fire Resistance

The laboratory tests results state that the Beno-Therm cellulose insulation procures an exceptional flame resistance and also proves that it is a non irritant product. Beno-Therm is used extensively in many large construction projects not only as an insulation and acoustical material, but also as an excellent fire resistant agent. Beno-Therm meets the CAN/ULC-S703 standards as well as the American ASTM C739 standard.



The Beno-Therm thermal and acoustical cellulose insulation contains soundproofing properties and proven superior performance. The Beno-Therm insulation is injected at a 3.0 pounds density per cubic foot in party walls before they get closed. The injection is done through a ventilated membrane with the Beno-Mat injection method. The membrane is stapled to the frame. For examples of walls assemblies, click here.

Ceilings and floors

For the ceilings and floors, the density should be 2.5 pounds per cubic foot. In the case of the existing structures, the application is done directly through the gypsum walls, using holes of two inches diameter. For examples of ceilings and floors assemblies, click here.

Controlled PH

In reason of its controlled PH, the Beno-Therm insulation is ideally suited for insulating steel-structure buildings where use of corrosive materials must be avoided. Entirely natural, the Beno-Therm cellulose insulation is safe for the environment.

Pest control

As a result of the minerals included in its formulation, the Beno-Therm cellulose insulation helps control pest intrusions. It has therefore gained considerable success in farm buildings roof insulation.
