Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used to control indoor temperature, humidity, and air motion to benefit thermal comfort and control condensation.
- Extractor Fans are used to expel stale humid air from wet producing rooms like Bathrooms, Kitchens and Utility Rooms. We recommend the use of silent continually running extract fans as these units do not require user intervention to enable them to extract. They continually run in a silent trickle mode and can be boost enabled by either a pull cord, light switch or a humidity sensor.
- Single Room Heat Recovery Fans are extremely efficient in rooms affected by condensation damp and black mould and installing the correct product and in the correct location, will almost certainly GUARANTEE a complete cure to condensation and black mould.Single room heat recovery fans are intended, as the title states, to be installed to improve air flow to the given room they are installed in. Do not expect them to service multi rooms as the fan speed and diameter of the core restricts the cubic volume of air it can change in a given hour.
- Positive Input Ventilation (PIV) is mechanical ventilation in the form of Loft mounted Vents or Wall mounted vents in flats and apartments.Positive Input Ventilation (PIV) draws less humid air in from the loft space, passes it through a filter to capture any dust particles and delivers clean, fresher air quality into the living space.
This in turn, replaces and displaces the stale air reducing the level of humidity. By reducing high levels of internal humidity Condensation and subsequent black mould growth are prevented.
Positive Input Ventilation (PIV) should not be installed as a stand alone solution for ventilation. Most important is to have good quality extract fans in the Kitchen, Bathroom and Utility room and there should be outlets for the stale air to be dispersed such as window trickle vents or through the wall passive background vents. Window and door openings also help in this regard.
- Passive Background Ventilation air vents installed for the purpose of improving internal air quality and in so doing, reduces humidity and prevents or reduces condensation damp.Air vents provide natural ventilation in the same way window and door openings do but for some reason, are not available or that cannot be opened and left open securely.
