Passive dehumidifier to increase room ventilation, helps prevent black mould.
An opening with airflow controlled automatically by a mineral wool slab, avoiding undue draughts, with an effective area well above the minimum requirement for habitable rooms. Kitchens and bathrooms will generally require mechanical ventilation to cope with the greater amounts of moisture generated.
Air tested by the Building Research Establishment for airflow rates versus applied pressure difference.
