The authority on premium window coverings in New Zealand, Luxaflex® appreciate this more than most. Not merely an aesthetic mechanism to block light or provide privacy, window coverings play an integral role in the capture and retention of heat, reflecting the sun and diffusing natural light when daylighting – all with the added benefit of reducing energy costs.

The degree to which these benefits can be realised is dependent on the orientation of a window, and correctly pairing window coverings that best manage the variables that exist. Whether north, south, east or west, each exposure carries with it a distinct temperament. We explore these and how best to utilise them below. 

Eastern exposure

Eastern exposed windows are best positioned to capture the early morning sun. It is best to consider whether the designated function of said space welcomes it. For example, in the case of bedrooms, an unwanted wake-up call may wish to be avoided, particularly in children’s bedrooms. Alternatively, those who are early risers may welcome this experience.

To cater to both parties, Luxaflex recommends the use of their Dual Roller Blinds. Featuring a twin bracket, Dual Roller Blinds allow you to combine the functionality of two different fabrics so that you can have daytime screening or filtering and night-time darkness. For added function, an automated system can be used to sync the blinds for a morning routine.

Western exposure

Western exposed windows provide the perfect light for rooms that see high use in the afternoons. However, afternoon glare and overheating can be an issue. At the same time, western exposed rooms are susceptible to being flooded with golden overtones, so staying away from oranges and reds is a must. To combat this, Luxaflex recommends soft translucent fabrics that will diffuse the light and reflect solar heat.

Luxaflex Silhouette® Shadings are a unique example of this, a statement piece with added functionality. Silhouette Shadings provide privacy and 99% UV protection when closed. When open, the shadings will not only diffuse light but also offer a soft-focus outlook to the outside. 

Southern exposure

Our homes receive minimal sun on the south, so a diffused soft light is received all day long. Although calming, we tend to have issues with heat loss on this side. To combat this, Luxaflex recommends that windows be kept relatively small and insulated.

Luxaflex Duette® Architella® Shades make a great insulating addition to any window, particularly those with southern exposure. Duette Architellas honeycomb structure with three insulating air pockets can increase the R-value of a 3mm single glazed window from 0.13 to 0.78, reducing heat transfer by up to 83 per cent.

Northern exposure

Northern facing windows receiving the most sun exposure throughout the day. Primary living spaces with large windows and doors are often positioned facing north to benefit from both light and thermal gain. Although this has its benefits, excess heat and UV exposure can be a concern here where the sun is most harsh.

In summer, Luxaflex recommends the use of window coverings with fabrics that offer solar reflection and UV protection to keep spaces cool and protect furnishings. As they have to be drawn to benefit, sheer fabrics are recommended to preserve views. Something like Luxaflex’s Te Rā Awnings could also be fixed to the exterior to achieve the same effect.

In winter, the opposite is encouraged. Large windows offer an opportunity to capture solar heat. In the morning, window coverings should be drawn and closed again at night to lock-in a day’s gains. Luxaflex’s Duette Shades provide a great thermal barrier to achieving this, while the ability to pair two fabric classes means they can be equally effective in summer.
