We’re about to start some work to the house and part of the job is a large (8m-ish span) wall that’s having floor-to-ceiling sliding glass doors. Plan is 4 x 2m(ish) wide panels, outer two fixed and inner two sliding outwards.

Where do I start looking for these things? I’ve seen a couple of places that seem to fit the bill but they’re the opposite end of the country (I’m in Fife, they’re close to London).

Cheers.
