Floating floor q

[meow2222]

'We would only ever recommend the use of adhesive floor fitting foam to create a floating floor. ON NO ACCOUNT should floorboards be glued together and floated.'

Why is this? I thought it was standard practice to do it this way, leaving an expansion gap around the perimeter. Where is the problem?

The message from [e-mail] contains these words:

I think you're thinking about laminate floors. That advice is about wooden floors.

and as I understand it engineered wood floors can be glued and floated but not solid wood tongue and groove because it is not dimensionally stable enough.

so it would shrink away from the edges visibly?

I suspect I may have figured out the big reason: cupping. Imagine cupping on a wood floor with boards glued side to side and not fixed down ha

I reckon that may be the main reason but also, maybe, different boards would have different expansion/contraction characteristics? Because of differences between pieces of wood the joints might be stressed along a row and pull apart?

yes. And before they do its 'oh we've got a speed bump in that room.'
