I am building an extension and doing a timber suspended floor, so need to get air down to the void. I will be using 3 air vents on each side of the building.
Generally i notice on new builds the air vent sits above the damp course, but i was wondering if i can sit the vent just under the DPC. I need to use these telescopic vents and i will come up 5 courses if the external vent has to sit above the DPC. Or 4 courses if below it.
