In modern home design there is a tendency to remove walls to create a sense of spaciousness. Devices that produce sound in the home are becoming more prevalent, such as additional appliances in the kitchen, surround sound, home theatre systems and other electronic sound / acoustic devices.
Also, more families are choosing to live in multi-unit dwellings constructed closer to major sources of noise pollution.
Finding the best acoustic insulation solution is the answer to reducing noise pollution in the home....
So, What Is The Best Acoustic Insulation?
Whenever air can leak through walls and around doors and windows, noise can leak through.
Icynene spray foam is a spray in place, low-density foam insulation and air barrier material that can effectively air seal wall systems and thereby provide a significant contribution to the homeowner’s need for noise reduction.
Insulate interior walls with Icynene spray foam when you want to minimize the transfer of noise between rooms, offering the best acoustic insulation.
While traditional types of soundproofing are not as sound absorbent, Icynene spray foam insulation is able to absorb sound waves of varying frequency levels. Icynene spray foam insulation can assist rooms and structures attain a sound transmission class of 50 or greater. In comparison, rooms with conventional soundproofing typically achieve a sound rating 27 and 34
When using Icynene spray foam the best practice is to partially fill the cavity, sufficiently to provide an air seal but also to provide an air space between the insulation and the interior drywall to provide a discontinuity for the transmission of sound. A dead air space within the cavity will serve to further reduce the transmission of sound through the wall, offering the best acoustic insulation properties.
Icynene spray foam fills every gap in the building cavity while adhering to all adjoining components for a tight seal. By greatly reducing airborne sound transfer, flanking sound, and the effect of drywall penetrations, walls insulated with Icynene spray foam serve as the best acoustic insulation solution.
