Ah well that's it then if you already have it. Generally tho, those systems, you lay the mat, put the wire in and it's good to go, goes down really fast, instead of having to put the wires down, level it, fit uncoupling mat on top. Work it out next time for cost
Wonder how it would compare in price?
Currently 10m2 160W/m2 Raychem mat £350
And if I had to buy the membrane say about £140
SLC say £40.
So about £600 ( Obviously not including cost of thermal boards)
