Question

The air brick in my wall, where does that let air to, right underneath the floor?

Answer 1

The brick will let air out either from the cavity in your wall or the void under your floor, to prevent moisture or gas build up.  

Answer 2

Helps prevent ground moisture causing damp. It lets it evaporate off.

Answer 3

Yes - you presumably have wooden plank floorboards and these need to be 'aired' so as to avoid damp/dry rot.  

In days of yore our Tudor ancestors dealt with such problems with flagstone flooring and airing wasn't necessary.

Nowadays it is - and it's important to ensure the airbricks don't become blocked by weeds or other stuff - especially if the building is in a 'flood plain'.

Water always finds its own level - so in the event of some of the downpours/flooding we have witnessed in recent years it will seep down into the soil and remain there - causing mischief to wooden floors, unless allowed to evaporate/dry off via airbricks..

Answer 4

Lets air in to the sub-floor, preventing damp and mould

Answer 5

Probably yes! It creates a flow of air to keep everything dry and rot free

Answer 6

it could, to prevent condensation under the floor and therefore causing damp or rot.

Answer 7

It circulates air under the floorboards to prevent any moisture collecting, which over a time can beginto rot the timbers and boards.

Answer 8

Yes it does. Why do you ask ?
