DualShades™ are flat roller shades with an insulated transparent lining for a technically advanced system combining insulation, extra view, and heat control. The ThermoVeil™ or EuroVeil™ sun screen is backed by a light-dimming MirroFilm® to further filter light and heat while enhancing its view-through ability and roller screen functionality. DualShades™ may be backed by blackout shade cloth to achieve privacy and/or room darkening.
