i have a 20ft x 7 ft loft apex tiled with 20 widowhood cocks in. all the top is netting (open) apart from 12" over the top of the boxes. Air comes in under the eves at the font of the loft and goes out at the back - or should!!
do i need air coming in at the bottom of the loft??
your help is much appreciated.
Can anyone help me out.
I dont seem to be able to get the correct ventilation in my widowhood loft. I have a tiled roof - apex loft, where should the air come in - bottom or top? and where should it escape?
