we are doing a build with a roof lantern the size we are having is 3.2x1.2m the manufacture only give the external measurements not the internal. The carpenter has constructed an upstand but the internal measurement is 96cm he said he does this so the plasterboard can be packed out and to allow adjustment to get the lantern square? But that of course makes the internal measurement a lot narrower. Is that correct?

How did the carpenter know what size to make it if he doesn't have the dimensions?
Because the manufacturer only gives the external measurements.
Has somone rung up the supplier? Unless you have it on site then how does anyone know how big to make the upstand?

Yes I spoke to them, they only give external measurement, the ingress is the same on both sides. Im buying direct from manufacturer so they will make to fit.

Surely they're able to tell you the inside measurements then?
Nope they wont give that, only external. No idea why
Lol... buy from a professional company then!
eBay seller?
it is a professional company, they supply most of the trade.
No, made for trade.
They are you can look them up online huge factory.
So they can't tell you how thick it is? If so then you could work out the internal dimensions from the external sizes.
