Most homes in Ontario are built with cavity walls, meaning there is a hollow crevasse between the interior and exterior wall. Most homes have drywall as their interior wall and plywood with brick or siding on the outside with the space usually filled with standard batt insulation. This is not enough to provide any kind of real privacy, allowing for loud noises to travel through fairly easily.
The best soundproofing comes from within your walls and ceiling, as sound travels through the air in this space fairly easily. Evergreen Premium Insulation completely fills the cavity between your interior and exterior walls to deaden noise and provide a sound barrier rivaling the quiet of recording studio acoustics, allowing you to simply enjoy the silence.
