Window Coverings Energy Efficiency


Energy Rating System

We developed this energy rating system following the comparison study where a range of products were tested in identical facilities using the same procedures and methodology as outlined in the Report “A Comparison Study of Various Window Coverings” peer reviewed by The University of Newcastle’s consulting arm Newcastle Innovation.

Efficiency Tests


Efficiency Test One

Impact a window covering has on the heat gain into a building.

Results are based on the difference in average temperatures taken over a 9.5 hour period, in two identical chambers. We initially tested the ultimate window covering, a 60mm polystyrene block to set our bench mark of 40%. Then a range of window coverings were tested and compared to a pane of glass. A comparison of the differences in temperature were measured over 9.5 hour period. For example: block out fabric roller blinds reduced the total heat into the house by 18.3% (based on satin white colour). In essence, the higher the percentage represents a better energy efficiency. Note that colour was found to be a major driver with satin white vastly outperforming satin black.


Efficiency Test Two

Impact a window covering has on the heat gain through window only.

Results are based on the difference in average temperatures taken over a 9.5 hour period, in two identical chambers. We initially tested the ultimate window covering (UWC), a 60mm polystyrene block to set our bench mark of 40%. Then a range of window coverings were tested and compared to a pane of glass. A comparison of the differences in temperature were measured over 9.5 hour period. For example: block out fabric roller blinds are 46.1% (based on satin white colour) as effective as the UWC at blocking out heat. In essence, the higher the percentage represents a better energy efficiency. Note that colour was found to be a major driver with satin white vastly outperforming satin black.
