The cool crisp look of a roller shades is a designers favorite. Efficiency and elegance explain its longevity in the world of windows. With 4 opacity options, screen fabrics let you see outside while still reducing glare and harmful UV rays. Choose a dark color for dramatic contrast, crisp view and reduced glare on brightly lit windows. A light color choice deflects heat and light, which increases energy efficiency, but softens the view. SCREEN OPACITY AND PRIVACY More view? 10% screen. Minimal view? 1% screen. And a couple of choices in between. 1% 3% 5% 10%. Even the most densely woven fabrics will not provide 100% privacy at night with interior lights on. If privacy matters, step away from the screens.
