Soundproofing – Cellulose acoustic soundproofing



Uréthane Supérieur offers high-quality expertise and many years of experience in soundproofing.

Our acoustic soundproofing is an effective solution for the following applications:

• Transforming an apartment building to condominiums
• Blocking noise coming from the floor above or below
• Blocking noise coming from outside

Sound transmission

Thirty years ago, carpeting was seen as a fashionable floor covering that was greatly appreciated for its acoustic insulation properties. Today, hardwood, engineered wood and laminated products are more often used in apartment buildings and condos.

Sound transmission is a common source of complaints from condominium owners and tenants of apartment buildings, both in the case of new constructions and renovated buildings.

The “Superior” solution

Over time, our product has demonstrated superior performance when compared to other acoustic products. Uréthane Supérieur injects its product at a density of 3.0 lbs per cubic foot in dividing walls and 2.5 lbs per cubic foot in floors/ceilings.

For existing partitions, the injection can be made directly through the drywall panels by making holes (approximately two-inches in diameter), which we seal afterwards with wooden plugs. For walls that are under construction, the injection is made through a ventilated membrane that is stapled to the frame before installing the drywall.

A significant impact on your quality of life

Our products are extremely efficient in terms of reducing noise and sound transmission:

Many factors can reduce the performance of soundproofing.
Acoustic performance varies according to a number of factors, such as acoustic or insulation leaks, mechanical bypasses, the size of the room, the height of the ceiling, and many others. Efficiency standards are still very poorly studied.
