New oak floor. Glue or Float?

[jamesr36]

Hello

I am about to lay my new floor. Engineered oak flooring. 20mm thick with ply backing. 170mm x 2100mm planks. I've got a concrete floor. Had it professionally levelled and treated with Sika rapid DPM.

Am I best to glue the floor down or float it. I have fitted a few floating floors but never glued. I assume that glue will give a more solid feel to the floor but floating will allow an underlay which might make the floor slightly warmer. I assume a glued floor will be more difficult to lay?

What are the pros and cons of glued?

Thanks.

Cons of glueing: your weakest link will be the bonding between screed (leveling compound) and the floor; it's more expensive than a normal Combi-underlayment (containing a DPM)
