When mentally putting together their dream home after watching their favourite architecture or home renovation TV show, few people‘s thoughts about windows would extend much beyond wanting to frame views, or perhaps wanting to maximise natural light. Most people are unaware of the various advantages and disadvantages associated with the various window types.

Whilst some things are common to all window types, like keeping rain out and letting light in, the variety of window designs commonly used in New Zealand have a number of differences in the benefits that they will bring to your building.

Notes:

1. Casement windows, like louvre windows, allow ventilation through virtually the entire window area, so deliver very good ventilation. Casement windows are also popular for their ability to funnel in air travelling virtually parallel to the outside wall. This same benefit can also result in breezes running in the opposite direction being blocked from entering through the casement window.

2. Altair Louvre Windows are the only window type which can offer good ventilation at any shape. For example, when tall and narrow or short and wide.

4. Windows in bathrooms need to deliver a combination of privacy and ventilation. All windows can have obscure glass (read more about Louvres in Bathrooms here) with a frosted appearance. But obscure glass is of no use when a window is opened wide to flush steamy air out of the bathroom.

To maintain privacy, bathroom windows can be opened very slightly. With Altair Louvre Windows, opening them very slightly maintains privacy while delivering reasonable ventilation due to the openings created on both sides of every blade. All other window types only have a single opening and so deliver very little ventilation when only opened enough to maintain privacy.

5. The New Zealand Building Code specifies that a 100mm diameter sphere must not be able to pass through the openable window that is installed one metre or more above ground level to prevent children from falling through them. Breezway Louvres comply with these restrictions but for most window types this has a severe impact on the amount of ventilation possible through the window.
