Sound proof insulation

Soundproofing your home or apartment

Reduce the unwanted sounds and noises and improve your quality of life with sound proof insulation.

Cellulose is the most efficient sound proof insulation product for ceilings and walls between apartments. It reduces to its maximum the transfert of noises from floor to floor. 

In Montreal, most of the duplexes and triplexes build before 1975 don't have any soundproofing insulation between their floors. This is really inconvenient when it come to noisy neighbours. It is possible to immediately resolve this unfortunate situation by injecting cellulose through openings in your ceiling. The process is simple and doesn't leave any traces. Our technique is suitable for both plaster and gypsum ceilings.

Frequently asked questions

How do you measure the sound reduction from an apartment to another in existing buildings?

Although it is difficult to answer this matter with accuracy, with the studys of the "Code du bâtiment" concerning the ITS ( indice de transmission de son ) adding cellulose reduces by 30% aerial noise from floor to floor. However the impact sounds such as heel hits are only reduce by a slight margin. 

Does your company do plaster job after injecting cellulose or do I have to hire another company to make the finition?

We don't have any problem with you having somebody who can complete the plaster job behind us. If you don't want to bother with shopping around for somebody to do it we can help you. We offer plasterer work after soundproofing so that everything is done and cleaned up rapidly, within 2 to 3 days.

Does cellulose also act as regular insulation in addition to soundproofing insulation in my walls and ceiling ?

Definitely. Condensed cellulose will cause heat to stay longer in your housing, heat goes upward which in this case will have a harder time going through your ceiling.
