Rehau completes largest chilled-ceiling project

The largest installation of Rehau’s chilled-ceiling system has been installed in 40 Chancery Lane in central London. This 8-storey building has more than 5000 m2 of ceiling using the radiant CoolBoard plasterboard system, which helped achieve a BREEAM ‘Excellent’ rating.

The project integrates an existing 19th-century building in Tooks Court with a new-build mix of prestigious office and retail space. The office space has been pre-let as the new London office for internal advertising and marketing giant Publicis Groupe.

Rehau originally supplied CoolBoard to provide radiant cooling in the lift lobbies following a CPD seminar given by the company’s specification team in the central-London office of consultant Arup.

However, when it was discovered that the ceiling voids would not accommodate fan-coil units, Arup and developer Derwent opted to use the CoolBoard system throughout all the office areas.

CoolBoard comprises plasterboard panels with integrated loops of pipework. Pre-drilled fixing holes on each panel make it quick and easy to fix to the ceiling grid. The pipe tails from the boards are connected using Rehau’s Everloc compression sleeve fittings, which guarantee no leaks.

The sheer scale of this project has helped Rehau develop more efficient methods of designing and checking details before going out to customers. This led to the development of what was originally a bespoke insulated manifold box assembly into a standard article on CoolBoard.

M&E contractor was Sale Mechanical, and the chilled-ceiling installer was Celtic Contractors.
