Hello , I wanted some advice for tiling in our new extension floor , I have 8x2 C24 floor joists spaning 3.9 meters long fixed to wall plates via bolts at 300 centres, each joist at the centre of the span is braced to the concrete floor via blocks. The floor is quite solid with no bounce, the room size is 5m x 3.9m which is about 20m2. Between the 8x2 floor joists I have to place 100mm of king span to satisfy building regs.
I want to install electric underfloor heating and 60x60 super white porcelain tiles
could you please advise my questions are as following :
1 can I use 18mm external ply straight on to the joist, and tile on top?
2 having placed 100mm kingspan (b reg requirement is only 75mm I think) in the joists do I still need insulated backer board under the heating mats ?
also which electric heating do you recommend and want about this insulating paint?
