Coolaroo Retractable Blinds will help to keep your family cooler in summer, warmer in winter, and reduce your energy costs at the same time. They are made from 'breathable', weather-resistant fabric, and they are a great solution for windows and patio areas alike. They are proven to reduce temperatures by up to 32 compared with direct sunlight (independently tested by CSIRO) and block up to 95 of UV rays with their knitted UV-stabilised high-density materials. The fabric resists tearing and fraying, is very breathable and ensures that hot air doesn't get trapped between the blind and window. Coolaroo Retractable Blinds protects interior furnishings from the sun and are suitable for wind out and standard sliding windows.
