Subject: Solid or engineered wooden floor

Should the wooden pieces be "glued" together?

For an engineered floor it depends on the type. click fit systems do
not
need glue.

Non-glue floors do need gluing, otherwise water gets into the cracks
and they delaminate prematurely. With wood glue youve got ages to undo
mistakes before it dries.

Egineered wood floors are far more stable than real solid wood in
terms of expand/shrink/warp, but are a lot more vulnerable to damage
by damp and wet. In practice they dont last anything like as long.
