I am building a timber framed workshop, which will be covered with
shiplap cladding.

I have 3 questions:

1. Should I user a membrane between the cladding and timber framing?

2. What sort on nails should be used the secure the cladding, and

3. At what points on the cladding should the nails be placed, under the
tongue for example?

Do you mean on the outside or the inside?

I have 3 questions:

1. Should I user a membrane between the cladding and timber framing?

Assuming you mean the outside, then it is probably only worth doing
that if you plan to put in insulation and an inner cladding or
surface. If you use a material like Celotex, it has a foil barrier
on both sides anyway.



2. What sort on nails should be used the secure the cladding, and

I used stainless steel ones in an air nailer. Otherwise galvanised
would probably be an idea. This is a very good project to justify
the purchase of a small compressor and air nailer (the electric ones
are useless) because you can save a huge amount of time.



3. At what points on the cladding should the nails be placed, under the
tongue for example?

You could secret nail near the tongues to hide the nails although if
the boards are wide, this may not provide enough fixing strength.

HI Lawrence

Funny you should ask - I'm having a 12' x 24' shed built at the moment
- it's clad with timber panels which are fixed to three welded steel
sections which form the uprights and the roof line...

Given that we're out here in a rather windy spot in S-W Ireland, Mr
Shedman has covered the studwork with 1000-guage black damp-proofing
plastic before fitting on the shiplap. Apparently makes the whole
thing much less prone to draughts and rain penetration.


2. What sort on nails should be used the secure the cladding, and

They used a Paslode 'gas' nailer - and the nails looked to be
'standard' (i.e. non-galvanised) ones

3. At what points on the cladding should the nails be placed, under the

Nice idea - but not all that strong.
They've just fired them in through the 'meat' of the shiplap.....
after all - it's a shed, not a work of art g

Actually - a word of caution.....
Make absolutely sure that the thing's watertight before you put the
chipboard floor down. Shedman & his crew nailed some more of the DPC
membrane over the top of the roof when they left on Friday.
On Saturday we installed a DPC over the concrete base - and then
expanded polystyrene, followed by t&g chipboard flooring.

Unfortunately...... over night a strong southerly gale arrived, ripped
off the membrane from the roof, and the rain which followed soon after
ended up trapped under the polystyrene by the damp-proof membrane.

Bother - said Pooh !

That'll teach me to be keen !

Spend a happy hour or so this morning fixing the sheet back on top of
the roof, and baling out the water under the chipboard. Grrr !
