Castellated underfloor heating insulation panels are designed to simplify the procedure of preparing the floor for laying heating pipes, reducing installation time with the profile panel assisting in quick and easy positioning of pipes. The sub-floor is laid with rigid thermal insulation boards which reduce downward heat losses and provide a base on which to fix the underfloor heating tube. The castellated panels are laid over the thermal insulation and the pipe is clipped into the panels.
