Under floor vent positions

[Vijay]

I know I've seen somewhere where it stated how far in from a corner and how far apart air vents should be for the underfloor ventilation, but for the life of me can't find it. I've read through Part C and although it mentions ventilation, it doesn't state the information I need. Can anyone help me with that?

 

Cheers

Scrap that, just found it, 2m spacing and 450mm from the ends of walls https://www.ribaproductselector.com/Docs/4/07504/external/COL31426.pdf   I assume the 450mm is from end of the internal wall/corner?

i think that I set mine every seventh brick

and two in from each corner

But you may find that you have to alter this slightly in places Just to make it look even

Our plans have them at slight variations between 1500 and 1600 centres apart. Our architects construction notes say a no more than of 1800 so I'm guessing the 2000 is a maximum.

Cheers. I'll try and keep them nicely spaced but aim for 1800 max where I can
