Boarding the ceiling and roof

[CATNAP]

Now most of the insulation is done I will soon be getting to fitting the inside walls and boarding the ceiling over the top of the insulation. Still got to insulate the roof, hopefully I have enough insulation board left.

Although expensive I'm thinking about ply walls and ceiling.
22mm plywood for the walls screwed into the stud walls and 18mm ply for the ceiling.... Is this a good way to go ? Someone said plaster board was an option but I think ply should be easier to fit and work well.

Is all ply generally the same? Is marine ply overkill ?

Hiya Catnap,

I'm using 18 mm OSB3 for roof sheathing, with metal tile boards over the top.

I'm using 11mm OSB 3 for wall and ceiling sheathing. I've just bought some at £13.16 a sheet delivered, with other materials.

While OSB 11mm might not itself be strong enough to screw shelves etc. to, you can devise ways for the shelves etc to be screwed through the OSB into the studs.

Yes I have already used OSB for the roof sheeting.
Metal tile boards? do you have a link? dont know what they look like.

You going to just paint the OSB for the internal walls?

The manufacturer's website is here - https://www.metrotile.co.uk

I shall be using up all my left over white matt emulsion for the inside and buying the cheapest when it runs out!

This what the roof looks like -

Yeah I just saw that stuff and would have considered it.... I went down the shingle bitch tiles instead....hopefully they last.

I'm not sure of the final effect painted OSB is going to give, might look ok if most of your walls are covered up with shelves and racking..... on this occasion my walls are going to be as plain as possible.

The ply seems like a stronger product as well, but its all more money lol .

fun and games

I've no idea why you would want anything so heavy for a lining on the inside of your external walls, but if you have a good reason, there is no harm in it. You'll never do this on your own, though. Get a friend or two to help, and you might even need a board lifter for the ceiling. Don't forget to leave a nail-width gap between boards all round.

Just shows how much I know ...hehe sure my carpenter friend said the thicker the sheet the easier it is to have biscuited together.... course I just thought Chocolate biscuits.

Biscuiting the sheets together ? Why on earth would he want to do that?

 

[CATNAP]

no idea now....cant remember the reason.... maybe to not see the screws.

I'm warming to the painted OSB now..... its 1/2 the price and doesn't look too bad from some of the pics on the internet.

so painted OSB walls and nice ply ceiling.

Well if OSB is good enough for the walls (and it is), then it's also good enough for the ceiling.

As for the biscuit comment, I suspect you two may have been talking at cross purposes. He must have been talking about something else. There is no way on this planet that anyone of sound mind biscuits sheathing boards together. There is absolutely nothing to be gained (I mean, they're nailed or screwed to the same piece of wood at the joins, so they aren't going to move differentially).

I found it useful to mark the position of the studs on the floor of the workshop. When the screw holes were filled and painted over it is surprising how difficult it can be to find the studs.

Or some annotated photos.

I'm think a smooth ceiling would look better against the textures of the osb painted walls bit of contrast. We want it to look smart after all not just like a workshop.

Good call
