Under floor vent positions

Recommended Posts

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
