Our Projects

Ventilation Systems to combat condensation.

Ventilation is not only the best way of preventing condensation in your home, it also improves indoor air quality by reducing harmful gases such as carbon monoxide and filters out dust particles, pollen, mould spores and other allergens to improve the overall well-being of occupants and their quality of life.

Our Services

Positive Input Ventilation Systems (PIV)

Positive Input Ventilation otherwise known as PIV Systems work by drawing in fresh, filtered air from outside in order to ventilate the house. It then forces air to circulate around the property to provide a constant flow of air to prevent air becoming humid and stagnant.

​

Systems are usually installed in lofts and take full advantage of the benefits of solar gain, distributing the heat in the loft around the property from a central hallway.

​

The PIV system also removes indoor air pollutants such as carbon monoxide and radon gas. The units are fitted with filters that keep out pollen and external pollutants such as traffic fumes when drawing outside air in. 

​

They are effective at controlling humidity levels throughout your home. Most PIV units are fitted with an internal temperature sensor that continuously monitors the temperature in the loft. This allows the unit to boost the air volume when the loft temperature is above a certain level.

 

If the loft temperature reaches a certain point then the unit will switch to standby mode (no airflow). Once installed, the airflow can be set to suit the house size and, if required, the way it responds to the temperature changes within.

Extractor Systems

Extractor fans are designed to extract stale, polluted, or damp air out of rooms which usually undergo alot of moisture such as kitchens, bathrooms, wet rooms,  cellars, garages and utility rooms. They work by reducing the humidity levels and prevent condensation.

​

Without extractor fans, moisture levels in bathrooms and kitchens can build up and cause condensation which can lead to damp and the growth of black mould. The moist, damp air in the wet rooms can also migrate around the rest of the property, causing issues in other rooms.

​

Extractor fans are required:

 

✔ To reduce humidity levels in bathrooms, kitchens, and other wet rooms

✔ To prevent the spread of water vapour and food smells from one room to another.

✔ To Maintain good air quality throughout your home.

​

Most homes will already have extractor fans installed, but over time, if the fans are not cleaned regularly, performance can degrade, and condensation can become a problem. Replacing older, inefficient extractor fans with new models will improve ventilation.

Key Considerations When determining which Ventilation System is right for your property 

  • Suitability for property – the type of property you are ventilating should determine which ventilation method you use. Bungalows and flats are different than houses. The number of wet rooms, the type of roof, your ability to install ducts and grilles all have an impact.

  • Costs – this includes initial outlay and running costs. Many ventilation systems have low running costs and the initial costs are offset in fuel efficiency.

  • Noise – units needs to be quiet, both during normal and boost modes.

  • Ease of installation – as well as the initial installation, you will want a ventilation system which requires very low levels of maintenance.

  • Compliance with the Building Regulation Ventilation Requirements – it must meet Part F & L England and Wales and contributes towards ‘conservation of fuel and power.’
