For a flash of brilliant white at the window this Duolight Bright White shade is just perfect.
Duolight shades are incredibly practical and totally gorgeous; the combination of energy-saving honeycomb design and light-diffusing fabric is wonderful and they look beautiful at the window.
Each honeycomb channel traps a pocket of air which acts as an insulating barrier at the window. The thermal shield keeps rooms warm in the winter, saving on heating, and cool in the summer, saving on air-conditioning.
The Duolight blind can be drawn down in the daytime and will allow gently diffused light into the room, this blind is an excellent solution for sunny rooms, not only will rooms be cooler but the problems of glare on tv and computer monitors will be removed.
