Chilled ceiling

Low temperature chilled ceiling solution.

A chilled ceiling system designed to provide a cost effective and energy efficient cooling for commercial and residential environments.

REHAU CoolBoard consists of a 15mm thick gypsum board backed with 15mm EPS insulation, with pre-routed grooves to carry 10mm RAUTHERM S PE-Xa pipe work. The panels are supplied pre-assembled with the pipe, along with an extensive range of fittings to secure the boards to the suspended ceiling or joists.

Pipe tails from the boards are connected to a manifold system to the supply of chilled water. The complete system uses high quality RAUTHERM S PE-Xa pipework and REHAU EVERLOC^TM fittings.

Unlike chilled beams and other ceiling systems, REHAU CoolBoard fits seamlessly with standard plasterboard ceiling panels in any plasterboard ceiling application. You may not be able to see the chilled ceiling panels from the standard panels, but you'll feel their effect.
