Condensation, Damp & Mould

There is now considerable evidence to support the view that mouldy housing has a detrimental effect on the physical and mental health of its occupants.

The Housing Health and Safety Rating System (HHSRS) identifies damp and mould growth as one of the 24 hazards which cause ‘risk or harm to the health or safety of an actual or potential occupier’

Damp and mould within the home may be a threat to health due to the increased house dust mite populations and mould growths resulting from dampness.

Causes of condensation in a property

Streaming windows, musty smells and mould growth are the obvious signs of condensation dampness in poorly ventilated homes.

Condensation generated by bathing and showering, cooking and breathing create the ideal conditions for mould to generate and dust mites to breed.

This damages the building fabric, causing premature decoration and replacement. Indoor air quality can be further decreased by pollutants from smoking, cooking, aerosols and naturally occurring Radon gas.

How dust mites affect health

Dust mites breed in a humid environment found in homes which are poorly ventilated.

Clinical evidence suggests that exposure to high concentrations of allergens associated with dust mites can trigger allergic symptoms such as rhinitis, conjunctivitis and eczema.

Repeated exposure to these allergens can lead to asthma.

Dust mites are too small for us to see but they can be present in huge quantities in soft furnishings, mattresses and carpets. It is the inhalation of this allergen that can trigger an asthma attack.

How we can tackle condensation

The problems caused by condensation can be easily overcome with the installation of one of our positive input ventilation (PIV) systems.

The installation process takes approximately 2-3 hours with minimal intrusion to your home.

What is Positive Input Ventilation (PIV)?

Positive Input Ventilation or PIV Systems work by encouraging the movement of air from inside to outside from a unit that is usually installed in a loft. These units reduce or eliminate surface condensation altogether by replacing humid stagnant air with fresh filtered air.

Take a look at the Nuaire Range of PIV systems.

The Drimaster–Eco range offers extremely low and cost-effective ventilation solutions designed with the aim of combating condensation and mould dampness.

How it works

The PIV system creates a healthy living environment. It significantly improves indoor air quality by removing indoor air pollutants such as carbon dioxide and keeping out external pollutants such as traffic fumes and pollen. It does this by introducing fresh filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside. This air movement forces the internal air which carries the pollutants that are in the house out and keeps the pollutants outside from entering the building due to the positive pressurisation of the property.
