Ecophon Master™ B

For applications where the minimum possible overall depth of system is required and where strict demands are made on good acoustics and speech intelligibility. The tiles are bonded edge-to-edge directly to the soffit surface, creating a ceiling with a smooth appearance. The bevelled edges create a narrow groove between each tile. The tiles are not demountable.

The tiles are manufactured from high density glass wool. The visible surface is available with three different surface coatings to meet different sound absorption needs: alpha (Akutex T coating), beta and gamma. The back of the tile is covered with glass tissue. The edges are painted. The weight is approximately 5 kg/m².

INSTALLATION: Intended for bonding to a flat surface as shown in installation diagram M113, which includes information regarding minimum overall depth of system. (However, if mechanical fixing is required, select Master C or F.) This method of installation requires smooth, clean and dry sub-surfaces of concrete, lightweight concrete, plaster or wood fibre. It is advisable to carry out adhesion tests on painted or suspect surfaces., CADsupport, Product selector, Specification, Maintenance manual
