CEMİNA

Lay-in system is formed by allowing aluminium or galvanised steel panels lean on T15/24 or T15/24 channel grid system.

This system is also called as “semi-concealed” as runners are visible but there is a shadow effect. All panels are demountable manually without any special tool so that the system enables fast and easy access to the ceiling void.

• Panels with 0.50mm, 0.55mm and 0.60mm thickness aluminium and galvanized steel
• Different perforations available: Ø2.5mm standard and Ø1.5mm is also available.
• Panels covered with an acoustic felt on the back like Soundtex or Royalin acoustic non-woven fabric.
• Standard Color is RAL 9010. With electro-static powder coating any RAL color is available.
• Panels are easy to demount thus enables easy access to ceiling void.
• Tiles are easy to mount along with lighting fixtures, ac and hvac units, fire hoses.
