part m tgd-door ope size.

Farmer Dan

Hello all. Did the regs in relation to clear opening width for doors change recently? Would a 910 mm ope meet the regs or would it need to be bigger?
Thanks in advance.

Internal. Haven't looked at frames yet. I have the opes at 910 but a rep from a door company told me yesterday they should be 950.

Thanks kceire.
The rep mentioned that this has changed last November. But I didn't hear anything about it. He must have his wire's crossed

@ OP - you need a 950mm structural for this

The Rep might be refering to external upvc doors - by this I mean that the frame on a upvc door tended to be wider than a timber door. So the ope size needed to be bigger to accommodate a door plus frames.

So that a clear size between frames plus door thickness could be achieved. 2 x 50mm frames + door thickness of 45 = 145mm.
A 900mm external ope width less 145mm = 755mm which would not comply. "The minimum effective clear opening width of the entrance door should be 800 mm" TGD M 2010 3.2.2 (c)

Hope that makes sense. This would require an ope of approx 950 for a upvc external door.

OP said it was an internal door.

910 is cutting it tight unless you use narrow frames , c.35mm.
50 for frame* x 2, + 45 leaf + 15 lock side rebate = 160
910 structural ope would be about 750 clear.
950 is a bit over, but he is probably rounding up to to neareat 50


*note: The frames are c.38mm, but a gap of 50 allows for fitting, packing wtc

That's correct, but neither you, the OP or I can be 100% inside the Reps mind. We don't know what the Door Rep was thinking. I offered the educated guess that the Rep was confused, as 950mm is not a requirement. It is possible that the Rep got mixed up with External door - making ope wider for upvc door to comply.

Who can say for sure.
