Ventilation- Retrofit Advice

Importance of ventilation

It is important to insulate your home and just as important to have adequate ventilation throughout your property. 

Poor ventilation equals poos indoor air quality which could be bad for your health as well as the building itself. 

Examples of poor ventilation

Evidence of condensation and/or mould growth in the dwelling;

There is no ventilation system or it is incomplete or not functional;

There are no undercuts beneath internal doors, above the floor finish, to allow air to move through the dwelling; or

There is no provision for purge ventilation of each habitable room (e.g. by opening windows).

Other ways to improve ventilation

There are simple ways to prevent poor internal air quality from becoming a problem by reducing the moisture you create and increasing ventilation. For example, you can put lids on pans when cooking, avoiding drying clothes indoors, use extractor fans in kitchen and bathrooms and keep window vents open if you have them.

Results in poor ventilation

Moisture is created in our homes through cooking, showers, boiling kettles – even breathing. If there is nowhere for it to escape it will build up on surfaces as condensation and this can lead to damp and mould growth. If allowed to develop this can cause damage to paint and wallpaper, lead to the growth of black mould and ultimately even cause damage to the fabric of the house.

Improve ventilation through installation

it will sometimes be necessary to improve the ventilation in your home through installing window vents or even a mechanical ventilation system. This includes installing extractor fans in all wet rooms (kitchen and bathroom)

Our retrofit assessor will carry out a survey on your property, based on the data gathered, the co-ordinator will then create a design in order to determine whether the ventilation is adequate or requires improvement. This will then be reflected in our installation process.
