Fans and roof ducts
Exhaust from the home's damp rooms is part of the modern ventilation solution
Extraction must take place in humid rooms, i.e. kitchen, utility room, toilet and bathroom, and the preheated supply must be carried out in all living rooms, i.e. living room, bedroom and children's room. The air must be able to flow from the living rooms to the humid rooms, either via a gap under the doors or via transfer vents between the rooms.
