Product Description

Sonex® Classic acoustical foam is the most well know foam in the industry. It is available in natural white, natural gray or charcoal(Color-Tec). The unique design of this foam is similar to a wedge design that offers more surface area for sound absorption. Sound energy is absorbed by this optimal pattern more than other similar foams. It is often used in recording studios due to its sound absorbing qualities and is very cost effective. Other popular uses of the Color-Tec (COC) version of Sonex Classic foam also include ceiling applications in restaurants, show rooms, demo rooms, school band rooms and office meeting rooms.  The Sonex Color-Tec is the only foam that is dyed charcoal completely through the foam. This dying process is much better than other foams that are painted which in time chip and peel away exposing another color that gives a star light effect. The Color-Tec will blend into a ceiling that has been painted black like many modern architecture is today. Sonex Classic foams are the number one choice for sound studios due to its unmatched performance.

Sonex Classic can be applied to walls or ceiling surfaces with water-based adhesives. For more information on this product or other Sonex Foam products call Sound Control Technologies today.
