OK, we have just purchased 15sq metres of Boen wood flooring. It is 15mm thick, engineered wood in 2.2 metre long, 139mm wide planks.
We have just laid a brand new chipboard subfloor on suspended timber joists. We used 18mm P5, purely because it is what we had already and the height works well with the adjoining floor.
We also bought some thin (2-3mm) white foam-style underlay, on the advice of the company that sold the flooring to us.
I was all set to glue the T&G's and nail the planks down, through the chipboard and into the joists. However, I am increasingly realising that perhaps I should lay it as a floating floor.
Boen suggest a minimum of 7mm expansion, with 1mm per metre of room width. So, for a 3.5metre square room, do I leave just 7mm? Also, would I need straps? Or can I tap it together using an off-cut of the T&G, as I have always done with chipboard?
If I do go for floating, is the underlay we bought OK?
