Cladding - what thickness

[timothyedoran]

I am going to clad in waney edge larch. I have the option of either 19mm or 25mm. Vastern timber are close to me and quoted 19mm @ £417 or 25mm @ £555 Inc vat.

I am leaning towards the 19mm as the chap said it would warp less if I fitted it before the autumn. Plus it is cheaper, which might be blinding me.

Which would you go for and why?

How wide are the boards?

One of my local sawmills is advertising thus: -

150mm wide £1.85 plm
200mm wide £2.35 plm

but......both are an 18mmm to 4mm profile.

I would have thought the 200mm should be thicker.

Yet, another advertises 200mm x 38mm.

And then another -

Stock lengths of featheredge

Feather edge boards are machined from rectangular strips of wood which are cut at an angle to make two similar tapered lengths. In addition to standard fencing lengths we also keep 150mm boards at lengths of 2.4m, 3.0m and 3.6 metres – these are all cut from 22mm timber. We also keep 175mm boards in 4.8 metre lengths (occasionally 4.2 metres) and they are produced from a thicker 32mm sawn board. The boards are unspecified softwood and then pressure treated with preservative.

It's a bit confusing for us amateurs!

Vastern states 200mm+ random widths.

The price list is here which maybe useful for someone else later.

Yes I agree very confusing. To be fair to the vastern man, he was helpful, but couldn't be drawn on how much better the thicker or thinner boards would be. He did advise waiting for autumn so the wood dries slower and then using the thicker boards. If I couldn't wait he recommended the thinner as it would cup less in the summer heat.

The problem is I can wait if it's better or I can order now coz it's cheaper. I'm not in a particular rush.

PS ordered the roof EPDM today. Photos of the roof partially decked to follow soon in my build thread. I might be the only thread with intact photos now post photobucket mess

I'd go for the thicker boards myself. You could even staple something over them temporarily if you wanted, to protect them from direct sun. Or I guess you could stack them, with sticks, and control the drying out process somewhat. The other trick is to put relieving cuts on the rear of them: run a circular saw along the back to divide the width by approx 3 (ie if the boards are 9 inches wide you'd have cuts spaced 3 inches apart), and cut a quarter to a third of the depth.
