Isowarm Castleboard System

A complete underfloor heating system incorporating insulation, pipework and associated retaining system and screed in a slimline solution. It provides a warm, welcoming surface in commercial environments, with energy and space saving qualities.

Isowarm Castleboard System and its clever pipe retention method ensures the precise location of pipes, which will not slip or float in the screed. A factory applied, vapour-resistant polyethelene membrane, together with interlocking tape-less joints, ensure that the system is resistant to screed water slurry. The system can be used in cooling mode with chilled water instead to reduce the dependence on all-air conditioning systems.
