In response to the growing need for a way to stop energy loss through windows, Hunter Douglas designed the Duette Architella shade, which has the highest R-value for window coverings on the market.
An R-value measures the thermal resistance of a product or material. A window without any window covering has an R-value of 1.25, whereas an insulated wall has a value of about 20. If a Duette Architella shade is added to a window, the R-value increases from 1.25 to 6.25, making a huge difference.
You might be wondering how a window covering can insulate a window and prevent energy loss? The three “dead” air spaces in the Duette Architella are the key in the energy saving technology. Believe it or not, air is a great insulator. Heat is “attracted” to cold, and the dead air spaces prevent much the energy from escaping through the windows. In the summer, the heat is kept out, and it the winter, the heat is kept inside.
Duette Architella shades can also block out 95% of harmful UV rays.
