The “openness factor” refers to how tightly fabric is woven and determines UV protection and light control, with options from 1-14% openness—lower percentages provide more insulation but less clear views, while higher percentages offer less insulation but better visibility.For privacy, choose shades with lower openness factors (1-5%), as tighter weaves provide excellent privacy while maintaining some outward visibility. Dark fabrics offer the best views through the shade, while light fabrics provide maximum protection from heat and UV rays.In Palm Beach Shores’ challenging climate, exterior shade materials must resist fading, mildew, and tearing while maintaining appearance in Florida’s humid, UV-intense environment. We help you balance view, privacy, heat protection, and durability based on your windows’ exposure and lifestyle needs.
