Hi, I have been making a staircase and originally allowed 19mm top and
19mm bottom (38mm total) as a guessed nominal finished floor level. (FFL)I was going to fit it but realised I need to know the exact FFL as the flight is bare wood (ie carpet can't hide a 1 or 2mm height diff). This is for the top landing as I can absorb a bit of slack at the bottom which will be tiled/lay stone.
I was looking at engineered wood flooring and most with a 3.6mm veneer seem to be about 15mm thickness.
THe top landing is a 19mm ply sheeting subfloor at the moment and I was going to gue the engineered wood to this. But then I see that alot of engineered wood flooring comes with an underlay.
Do I need this ? If I do what sort of thicknesses are they ?
ie I need to know the FFL to trim the stairs and if a 15mm eng floor needs 1mm of glue or 3mm of underlay I will need to add this...
Any advice ?
Cheers Ed
