Floating engineered wood floor - membrane required?

[echoes]

Hi everybody,

I will be laying a floating, engineered wood flooring in my kitchen. I'm happy to use 5 mm fibre boards for the underlay but I suspect that a damp-proof membrane would be a good idea.

Half the kitchen floor is screed, with cellotex, on top of block & beam. The other half is 18 mm chipboard suspended on joists. The threshold between the 2 is completely level.

Is a DPM advisable, and if so, what would you advise? (Plastic sheeting, bitumen-backed building paper etc.)

Many thanks.

You only need a DPM if the floors damp. The chipboard certainly isn't, and as there's cellotex with screed on top of it, that shouldn't be either.

Go with Timbermate Excel. Best underlay on the market imo.

Thanks Doggit. I might give the membrane a miss then.
