Tiling onto new build chipboard subfloors. - TilersForums.com

[Rich Midge]

Hi all, just wondered what methods people prefer? We are due to start a new build house next week with approximately 150 metres 60 x 60 porcelain to lay. The chipboard subfloor is well screwed down though I don't know yet if if extra noggins were put in. There isn't enough room to overlay with 15mm ply so we're looking at some kind of anti fracture membrane or tiling direct to wood. We're currently having issues with Norcros permalayer and have lost confidence with it in this kind of situation. I like Durabase, but the client doesn't want expansion strips. Any other suggestions would be greatly appreciated!

Will hardie guarantee this method? No More Ply maybe as another possibility?

only heard bad things on this site about no more ply that will never be a consideration to me.
