When floating solid or engineered wood floors, does the T&G between each board need to be glued? Each manufacturer has it's own patent on their T&G connection, and most are pretty solid once they 'click' together, so I wonder whether glue really is necessary?
Also, can floating floors be laid directly onto concrete (as long as a DPM is present) or timber floor boards/chipboard? Or is it recommended to lay a lining between the existing floor and the new floated boards (acoustic and insulation properties aside)?
