Minimising discomfort from cold draughts and noise
Discomfort from cold draughts can be avoided by positioning vents close to the appliance, drawing air from other building parts, or placing vents near the ceiling. In noisy areas, noise-attenuated vents may be used without diminishing air supply, subject to Part E Building Regulations.
Any discomfort from cold draughts can be avoided by placing the air vent close to the appliance, drawing air from other parts of the building or by ensuring a good mix of the incoming cold air by placing the air vent close to the ceiling, see Diagrams 2.2 and 2.3. In a noisy area, it may be necessary to install proprietary noise attenuated air vents to limit the entry of noise into the building but these should not diminish the required air supply. The location of air vents should not breach the requirements of Part E of the Building Regulations.
