Understanding how to ventilate a room without windows is vital if your home has – or will have after an extension, remodel or some kind of conversion – any rooms without any openings to outside. 

Good ventilation is essential, but without windows, it can be difficult to remove stale air from, and introduce fresh air into, a room — plus in hot weather, these spaces can become stuffy and suffer from overheating. When damp air is allowed to remain in a space – for example in bathrooms or the kitchen – problems such as mould and damp can also occur.
