The Australian Window Association (AWA) estimates 40% of a home’s heating energy is lost through windows and up to 87% of a home’s heat is gained through windows.
And with electricity prices rising, choosing energy efficient fittings has never been more important.
Crimsafe screens have undergone a range of energy efficiency testing and have been shown to improve the energy efficiency of a window by up to 53%.
When you choose Crimsafe, you’ll not only stay safe and look smart, but you?ll save money on your energy bills too.
The Solar Heat Gain Test
A major element of determining a window’s WERS (Windows Energy Rating Scheme) rating is its Solar Heat Gain Coefficient (SHGC). The SHGC is the measure of how well a window blocks heat caused by sunlight.
To test this, a Crimsafe security screen is applied over a glazed window to measure how well the screen blocks heat produced by sunlight entering into your home.
Crimsafe Security Screens were found to improve the energy efficiency of a Window by up to 53%.
When Crimsafe is applied over a 3mm generic single glazed window the cooling efficiency of the window increases from zero stars to a 3 Star cooling rating, keeping your home cooler in summer and reducing heat loss in winter.
The Window Energy Rating Scheme (WERS) recognises that Crimsafe improves the cooling and heat retention of a building when applied to glass windows and doors.
The effects are best seen when security screens are placed over your entire window, not just over the opening portion. The type of window glass and glazing will also impact cooling and heat retention.
When Crimsafe is applied over a generic single glazed window the cooling efficiency of the window increases from zero stars, no additional benefit to a 3 Star WERS rating with a reduction in solar heat gain of up to 53%, keeping the interior of the home cool in the summer.
In the winter months Crimsafe works with your windows to limit the escape of warmth from your home, and heat retention efficiency increases. The heating rating improves from zero stars no heat retention benefits, to a 1.5 Star WERS rating with Crimsafe applied.
When Crimsafe is applied over 6.38 Clear Low E glass, the cooling rating increases from a 1.5 Star rating to a 4 Star rating greatly enhancing the cooling attributes of your glazing investment.
Annual energy performance (stars and % improvements) are calculated using Nationwide House Energy Rating Software according to procedures of WERS 2008 and the results are presented in Standard International Units.
