Thanks for the replies, I anticipated using the fibre underlay due
to the slight differences in level, wasn't aware I should lay it at
diagonally.

Only way to avoid a join in the underlay coinciding with a join in the
laminate flooring.

Floorboards are on short span so laminate can go
longways towards the window.

Short span? Wot dat?


All the professionals I know put down a damp proof membrane on every
concrete floor.

Agreed, but according to the OP its not a concrete floor - if I read things
correctly?
