floor panels which are quick and easy to lay, allowing you to                                                                  for heating upper floors, where it is often a difficult task to
install underfloor heating in a room of any shape or size.                                                                     manoeuvre around the floor joists.
The piping is then fitted into the floor panels and covered with                                                               Modular Heating Panels deliver a pre-configured solution that
screed before laying the floor covering on top.                                                                                can be easily fitted and connected together on-site.
The Polypipe Solid underfloor heating system is ideal for ground                                                               What’s more, Modular Heating Panels do not have to cover the
