Ventilation systems
to improve Indoor Air
Quality in the home

Improving insulation or increasing the heating in a home, which can be difficult or cost prohibitive, is not the solution to eliminating condensation and mould, but properly designed and installed ventilation systems are.

Effective, Efficient Ventilation

The key to effectively combating common ventilation problems is a properly designed, installed, commissioned and operated ventilation system that has been tailored to suit the home and it’s occupants.

Common Ventilation Problems in the Home


Excess moisture within a building; condensation is visible on cooler surfaces such as windows and is especially common in cooler months.

Smells and Odours

The strong odours of cleaning materials, perfumes, animals, fresh paint and new furnishings all contain compounds that can cause allergic reactions.


Microscopic mould spores result from warm, poorly ventilation rooms with excessive condensation and can grow in just four hours.


Microscopic mould sportes are easily inhaled and can aggravate eczema and respiratory conditions such as asthma.

Dust Mites

Found in most household soft furnishings, dust mites breed rapidly in humid conditions and their exoskeletons and droppings are easily inhaled.

Noxious Gases

Everyday household activities and appliances, such as heating systems and cooking, release potentially lethal gases into the home.
