Plaster with Absorptive Characteristics - August 28th, 2008
We are all familiar with a high reverberant space, such as cathedrals. We often go to restaurants that due to the large space and also the reflective surfaces all around, make speech communication virtually impossible. A similar problem occurs in a home cinema installation due to the reflective areas. That would more likely mean poor dialogue intelligibility, and a cinema room which is not as pleasant to use. The home cinema should offer reflection control treatments, to ensure a neutral sounding environment.
Some acoustic absorptive surfaces would solve the problem easily, but the finished look would more likely not satisfy the interior designer’s requirements. The interior designers would prefer the acoustic treatment in certain home cinema rooms to be hidden, and not have a visual impact to the final result.
There is a solution however. BASWA offers a plaster that can be applied over mineral wool. The plaster has a smooth finish, similar to hand-troweled plaster. The top layer’s structure has open pores, so it allows the sound energy to reach the mineral wool underneath. It is not gypsum based plaster, although it might look like it is. It is a water based emulsion of marble particles, which stays micro-porous after the installation.
There is an unlimited colour choice, which makes it a very unique solution for creating a discrete home cinema room, with excellent acoustic properties, but no visual impact.
