Is 8 x 1 tgv larch cladding too wide ?

[Hedjmunky]

Have just got some 6 and 8 inch tgv larch boards for vertical cladding to go on my wood frame extension, research suggests that 8 inch is too wide and that the tongues may pop out in the summer, its west facing with a 1 metre overhang , should I get them ripped in half and regrooved (I like the different widths ) or loose 2 inches off 14 x 3.6 metre boards , Either way I'll have to pay for more boards and machining . your thoughts please.

So long as it's fixed well I would've thought you'd get away with 8", the larch I've seen lately on the lorries has been rather excellent, to be honest, very fine grain and very straight and I reckon they'd be pretty stable. Of course, that's only from what I've seen and what you have may be of lesser quality.

My personal preference if I had to cut them down would be same width boards, but there's no reason you couldn't do mismatched if that's what you prefer.

Yes get them ripped in half and buy the extra timber at 5" to give you a good mix.

Thanks guys, sorry for the late reply, I got the 8 inch recut to 4, (luckily I over ordered) and they look great, didn't pop out this summer,used the leftovers for window surrounds, nearly finished the East side which is local waney edge Lelandii ! Will post some photos when I work out how to.
