When picking a ventilation system, you may notice that the listing includes a Decibel (dB) rating. dB ratings for fans represent an average reading from a 3m distance without ducting, taken in a sound-controlled room to give as accurate a reading as possible. This offers a comparative measurement between systems but not an accurate reflection of installed noise levels. Once installed, there are many variables that can affect the perceived noise of a running fan such as the length and type of ducting used; the shape, surface type and size of the room; the type of grilles used; the position of the fan unit (especially with loft mounted units such as inline fans) - making it very difficult to predict exactly how loud the system will be perceived once installed.

Noise Control involves applying techniques and measures to minimise or manage the noise generated by ventilation equipment, aiming to create quieter indoor environments. This is crucial in residential, commercial, and industrial settings to enhance comfort, reduce disturbances, and comply with noise regulations. Key techniques for noise control in ventilation systems include selecting suitable equipment, employing vibration isolation methods, utilising correct connectors, ensuring proper equipment maintenance, optimising airflow management, and strategically planning equipment placement. A comprehensive approach to noise control helps create more pleasant indoor spaces for building occupants.

Part F of the UK Building Regulations focuses on ventilation requirements in buildings, addressing both dwellings (Part F1) and non-dwellings (Part F2). These regulations aim to ensure health, safety, welfare, and energy efficiency. Part F1 outlines standards for residential ventilation, emphasising indoor air quality and moisture prevention. Part F2 extends these standards to non residential buildings, covering areas like extraction rates, ventilation strategies, and energy efficiency. Regular updates and amendments occur, so consulting the official government website or local building authorities is crucial for compliance with the latest regulations.

Bathroom electrical appliances, including extractor fans and lighting, receive an IP or Ingress Potential rating indicating their suitability for specific zones. The IP rating consists of two digits following 'IP,' where the first digit denotes protection from solid objects. However, our focus is on the second digit, representing protection from water and moisture. A higher second digit implies increased protection against water ingress. An IP rating of IPX4 or higher is safe for installation in zone 1 of a bathroom on mains voltage when installed on an RCD or RCBO protected circuit.

Firstly, keep your windows closed, this may seem counterintuitive when you’re standing in a room full of steam. However, an open window in midwinter is one of the main contributors to condensation, mould, and damp problems in UK homes. This is because when the cold air from outside mixes with the warm humid air from the shower it forces the moisture to condense faster forming into larger droplets of water. Keeping the windows closed helps to keep the room warmer and reduces the speed at which water molecules in the air condense making them easier to extract. Additionally, the cold air cools the tiles and other surfaces in the bathroom which adds to the speed at which the moisture condenses.

Wipe down excess water after showering. All that water collected on the wall tiles, shower screens, mirrors, windows and shower trays has to go somewhere. Yes, some of it will go down the plug hole, but most of it will evaporate and add to humidity issues or soak into surfaces causing further damp and structural issues.

So, invest a few pounds in a shower squeegee and spend a couple of minutes getting rid of that excess water. This not only effectively removes all water droplets it will leave your glass and tiles looking squeaky clean!

Indoor Air Quality (IAQ) refers to the cleanliness and healthiness of the air inside a building. It involves factors like airborne pollutants (dust, pollen, mould spores, VOCs), temperature, and humidity. Maintaining IAQ is crucial for occupant well-being and comfort. Key aspects include proper ventilation to exchange indoor air, control moisture, and enhance oxygen supply. Ventilation systems, including fans and filters, play a vital role in improving IAQ and involve effective ventilation strategies for minimising pollutant sources. Regular monitoring is essential for a healthier indoor environment.
