Does it matter if I use 4" or 5" feather edge for cladding?

Hi all,

Supply issues are driving me nuts.

I'm going to be cladding a small garden building in treated featheredge. Does it matter whether I use 4" (100mm) or 5" (125mm) boards?

Well it wouldn’t bother me. If I could only get one size, that’s what I’d use.

Do remember that the narrower the board the more you will need. A 4" board will only have 3" cover when you allow for the overlap.

Thanks guys. Still works out marginally cheaper for me to use more of the thinner boards - not enough to make much of a difference.

My main interest is doing it the best way for longevity. But if board width doesn't affect that, then I'll use the thinner boards because it's proving harder to source the wider boards.

Ok. Just remember - thick edge down, only nail inch and quarter up from bottom edge and overlap by no more than an inch and no less than three quarters of an inch.

The board above will hold the thin edge in place and the boards won't bulge or split with the boards swelling or shrinking with the weather.

That way if you have to replace a board you only damage the one you are replacing.

Allow for more nails using narrow boards

I would go for 6 inch actually from past experience - a lot easier to work with and you don't need so many lengths.

With the timber shortages as they are at the mo I think peeps have to make do with what they can get, or wait goodness knows how long

There be plenty down here in Devon and the shortage bits are no good anyway, he likely needs long bits.

others may disagree but feather edge and longevity for a shed do not come to mind
if you are going the whole hog with insulation breathable membrane air gap etc why not go for txg shiplap ??

Thinking bigger looks better.
