What are the different edge types

The Eurocoustic range includes three edge types – one square edge and two rebated (tegular) edges.  Different edges can be used by designers to create a different ‘look-and-feel’ to the ceiling.  The three types available are:


Eurocoustic MINERVAL and TONGA are available in A-edge, E15 edge or E24 edge types. Eurocoustic TONGA LS, AREA and CLINI’SAFE are available in A-edge only. Eurocoustic ERMES is available in E15 and E24 edges only. 


What are Eurocoustic tiles made from?

Eurocoustic tiles are manufactured using basalt stone wool, which is compressed into a stone wool core and laminated with reinforcing fleece front and back.

What colour are Eurocoustic ceiling tiles?

All tiles are factory-finished white.  While there is no specific RAL reference, the nearest RAL colour RAL 9016.  CasoLine QUICK LOCK grid is manufactured to RAL 9106
