Absorbing wall lining for internal and external application with natural stone effect. The material is non-flammable, clean for ecology (without fibres) and with good mechanic, climatic and chemical resistance.

Shape

The slab with plane face, bevelled corners with clips on the rear back to install into the bearing framework.

Material

Sized coloured sand, bound with use of epoxide composition. For need of external application, the face of wall lining is provided with silicone enamel protection coat.

Application

Acoustical treatment of minor rooms – restaurants, coffeerooms, offices, shops, indoor lecture halls and studios, habitable rooms, etc.

Installation

The lining is installed on the wall with air cavity on the metal framework, that has surface finish of ground coat or zinc plated. Area between frame and the wall can be used for technologic distribution. The lining can be dry cut to required dimension with use of diamond-charged grinding wheel or disk sander. Holes in lining (e.g. sockets and witches) can be drilled with heavy metal tools.

Maintenance

Dust on the lining can be cleaned with vacuum cleaner. In case of hard impurity use a solution of universal detergent in hot water and apply it with brush. Impurities from oil products can be cleaned with solvent.

Packing
