General

A rectangular sound attenuator with circular connection spigots.

Unique properties regarding installation height, fire-resistance class, fibre-migration proof design and sound attenuation.

Patented in terms of the self-supporting fibre-migration proof surface.

Function

When we developed the new CLA, we based the design on what we consider to be the three most important characteristics of a sound attenuator. First and foremost, we wanted to create a product that occupies as little space as possible. If the occupants are to perceive a space as being light and airy despite limited ceiling height, then it

is desirable to arrange the suspended ceiling as high as possible and this makes ventilation products with minimal installation height supremely interesting. Small installation dimensions also markedly increase the scope for instal- lation and make the installation work much easier. The other aspect was the fitters. Building construction workers and fitters complain much too often about sharp corners and sharp edges on the products they handle. We under- stand exactly what they mean and promised ourselves that we would change this and make their workday both sim- pler and safer. The third and perhaps the most important requirement we set up when we began developing this product was that low installation height and installation- friendliness absolutely must not impair the sound attenu- ating properties of the new CLA, preferably the other way around.
