muse if you’re room is air tight you won’t be able to breathe. Have you thought this through properly ?
According to the building regs these days all new build have to be airtight to a certain level. Leakage can be no more than 10m³/h/m²@50pa — or 10m3/hr. In other words, the amount of air escaping is as low as possible.
We've put in a mechanical heat recovery ventilation system, to maintain a healthy atmosphere. No moisture in the air. So no window vents, extractor fans, letter box etc.
Council will do an air tight test before signing off the house and give an energy certificate.
Discogran. Yes.
