How do you combat the problem of condensation in new builds? External moisture buildup occurs as a result of weather conditions, but internal moisture can be more difficult to combat. In new buildings, internal moisture levels are often much higher due to the initial moisture content of construction materials such as concrete, timber framing, plaster and paint. The windows and doors you select can help reduce condensation from both internal and external sources of moisture.
The windows and doors you select can help reduce condensation from both inner and outer sources of moisture.
Choose windows and doors that keep out moisture effectively
The windows and doors that best protect against condensation are expertly designed to withstand dampness from both outside and inside. Builders and specifiers are required by the NZBC to use products that perform well in terms of minimising condensation levels. Clauses E1 (surface water), E2 (external moisture) and E3 (internal moisture) were put in place to reduce the dampness, damage and degradation of homes due to moisture buildup. So, you'll need to select products that comply with these requirements - and ideally far exceed them.
Here are some things to look for when selecting windows and doors that will safeguard against internal and external moisture sources.
Double glazing in windows
One way to prevent window condensation is to use double glazing. According to WGANZ, double glazed windows help maintain a warmer glass surface, reducing the chances of condensation forming. However, as Build Magazine points out, double glazing isn't adequate on its own to prevent condensation.
Thermally efficient window frames
Using double glazed windows and doors together with thermally efficient frames will further assist in the prevention of the transfer of heat energy through the frames and reduce condensation, according to WGANZ.
Innovative drainage and ventilation systems
Proper drainage also assists with moisture reduction. Our awning windows have a cleverly designed drainage system that helps decrease the amount of condensation that forms on the windows, while our casement windows are equipped with a special condensation channel.
The Ministry of Business, Innovation and Employment pinpoints ventilation as another moisture reduction strategy. You can combine casement and awning windows with doors such as our Eurosliders® (pictured below) to offer greater ventilation that will minimise moisture levels.
Combine Euroslider® doors with casement or awning windows for greater ventilation.
Choosing the right supplier will ensure that your windows and doors are performing well when it comes to keeping moisture levels down in new homes. Talk to Altus Window Systems about our quality products that will help minimise the levels of condensation your new build experiences.
