Hi,
Background (Single brick wall, 50mm air gap, stud wall with 75mm PIR - Used as a Tropical Species Reptile Room, so highish humidity potentially.)
I am after advice on where to place vents for my cavity wall.
Does it even matter? I have read I need 1 vent per 2msq?
I have built a stud wall that connects itself on 2 walls, a side wall, and a back wall. (Please see image as I am bad at explaining).
Given the walls are connected within the same cavity, can I get away with vents only in the end walls?
The back walls go in to an area which I would absolutely struggle to get down to.
I was thinking 1 vent middle bottom, and 1 top - close to the back wall to create a flow through rather than a single vent, (If I even need 2?)
In the image the green section is one cavity, the blue another, they are not connected, so I would duplicate whatever I do for both sides.
Thank you.
