Hi

I've recently bought a book detailing how to install hardwood floors as
I'll be installing an oak floor. However, the book is american and states
that you should use three-ply kraft paper when boarding over exisiting
floorboards. This acts as a moisture barrier, reduces noise and provides
a clean working surface. Can anyone tell me what the UK equivalent would
be and can I get it from somewhere like B&Q? The book also says that you
should not use a polythene moisture barrier if that helps.

Many thanks

Mat.
