Door frame gap (B&Q Shannon)

I'm going to build a stud wall across a large room, and to start with we want a large open doorway in there, with a thought to adding doors later on. B&Q do some doors called Shannon which allow 6' or 8' openings (they are bi-fold). The doors are available in widths of 579mm & 290mm So a pair of each covers: 1738mm

But the advertising hoarding says: 1846mm

This implies a total door frame width of 108mm, or 54mm each side.

I thought door frames were normally 25mm thick? I thought 6mm per hinge is the tolerance too? So that would add up to 25 + 6 + 6 + 25 + 6 + 6 = 74mm, not 108mm

What am I calculating wrong?

The doors are 1981mm high and 35mm deep.

I want to ensure that I leave the right size hole!

Thanks Painters10

Painters10,

Internal door linings are usually 11/4" thick - with regards to the frame size: In your case, as you are building a stud partition, then simply make the hole in the partition (a chippies dream job) to take the lining at whatever size you wish (make the linings to suit the doors).

Not sure what you mean by a 6mm hinge tolerance, but if you mean the "gap" between door edge and frame, then using simple butt hinges, 6mm is rather excessive (remember, this type of hinge is sunk into the door *and* frame [try something like a 'penny' joint]) between frame and door.

Personally I wouldn't want to make the hole or commit to doing so without having the doors themselves in my hot sticky little hands. That way you can measure them up properly yourself and also be sure that there'll be no delays later when you come to fit them and find they're out of stock for the next 2 months. Or worse, out of production...

yes, I've learn that one too :( If you must work without buying them, at least find a second source of the same size so you're not dependant on one retailer's marketing whims.
