Castellated Underfloor Insulation (28mm - 47mm)

Castellated underfloor 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.

• Simplify the procedure of preparing the floor for laying heating pipes
• Reduce installation time
• Quick and easy positioning of pipes

• Castellation on castellation joining means that there is practically no waste

• The castellations ensure that the heating tubes are kept securely in place

• One board for several pipe dimensions

• The special castellation design enables flexible use for 14 to 16mm heating pipes

• Manufactured using the Combitop deep-drawing process

The castellated underfloor insulation panels are a thermoformed high-impact EPS with a polystyrene film bonded to its upper face that protects the board from mechanical damage during its installation and acts as a vapour barrier.
Castellated board is 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 with no further fixings required. The board’s interlocking profile eliminates cold bridging whilst its integral moulded skin acts as a vapour barrier eliminating the necessity to lay and tape polythene sheets.
