S/H French Doors in extension?

[jackg]

I have been offered a pair of double glazed UPVC wood stain external French Doors for an extension for which I have planning permission.
Not sure of age, 10-15 years?
Not sure if they satisfy current regs.
How can I check to see if they do?
Seals and glazing thickness are the factors at a guess.

Check with BC officer they will know for sure, or you could just risk it and then replace the glass if they spot it as a issue.

u value of 1.6 is required via DG units minimum air gap of 16mm.
So I need to check the thickness of the existing glazing air gap, 6mm or 12mm or thicker.
So any new units maybe thicker and may not fit into the existing rebate.
assuming BC check this.

Check there are safety marks on the corners of the DGU's. Safety glass aside, is it worth the faff? You will be having to make the brick-work suit the door rather than the other way around. Have they got trickle vents? There will be zero guarantees with the units. Are they a conventional 2100mm tall?

I know what I'd do.

If the extension was started after October of last year the windows and doors will also need to be document Q security rated with laminated glass too. Very few modern doors meet this reg, They have to be ordered specifically.

The extension has not been started, so thanks for the update on the regs, BC said nothing about that though.
I passed on the doors, be a pain to store them until I need them.
