Ground Floor Laminate question?
 

SWMBO insists that we get laminate in the living room. :(

Planning on using the fibreboard-y underlay as there a few areas with a
1-2mm difference in level and an old concrete hearth. Under the
existing floor there's about 500mm gap down to an earth solum, so will
I need any sort of damp/vapour barrier under the underlay?

TIA for any help.

If it's bumpy laminate floor won't lie properly. You shouldn't
need a DPM, but it there's any question of damp, put one in.

The thicker fibreboard underlay will easily allow for 1 -2 mm difference in
level, Don't forget to lay the underlay diagonally and the laminate at 90
degrees to the floorboards.

Got a dog by any chance ? - the noise of them scuttling around can be
quite bad, and they can have trouble getting up off the floor if
they`re getting old and creaky :-}

We've got a hamster!

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

No signs of damp anywhere, so I'll not bother with the damp proof membrane.

All the professionals I know put down a damp proof membrane on every
concrete floor. If the fitting instructions say use a damp proof membrane
then use a damp proof membrane. If there are any future problems with
warping or joints "tenting" you wont have a leg to stand on.

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

Short span? Wot dat?

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

Sorry, reverted to structural engineer mode. Short span is the "width"
of the room, the usual span of the joists, consequently, long span is
the "length" of the room. So I'm planning to lay the boards
perpendicular to the joists.

And you're quite correct that it's not a concrete floor, 500mm gap under
the joists to an earth solum.

Always use a DPM when laid on a concrete ground floor ... personally I use a
3mm closed cell underlay with a built in DPM (UniClic product), if you
don't want to use that then lay a polythene sheet down first ... you can buy
this in small packs in B&Q or builders merchants or in large rolls .... buy
the thin clear polythene sheet, not the thick black DPM.
