Underfloor Heating

[thompsonbrown]

when you say Styrofoam as insulation do you mean cement backed foam boards such as marmox or orby also you can get thermal primers which will reduce heat loss.

The ones I've got are Styrofoam Close Tolerance Extruded Polystyrene insulation boards provide a high thermal barrier between sub-floors and floor coverings

just check with supplier of boards, whether there suitable for your needs. the only blue foam boards i can think of are for underfloor heating under wood or laminate floors over a concrete floor

Yes got me worried their most blue ones ive been looking at have been for wood floors but i remember site said for . supplier says "Styrofoam Close Tolerance Extruded Polystyrene insulation boards provide a high thermal barrier between sub-floors and floor coverings; this increases the efficiency of any under floor heating system by reducing the heat loss into the floor structure.
Extruded Polystyrene is a 100% closed cell foam and is not affected by moisture. With a compressive strength of 300 Kn/m² the boards are an ideal product for areas with excessive loadings and high foot traffic. The Close Tolerance cut face of our Extruded Foam makes an excellent surface for installing ceramic and stone flooring and ensure all the boards are level when butted together, any bonding should involve solvent free adhesiv.

This is off ebay though.
