During these hot summer days we're all about shady business. We're talking about windows shades, of course. The Coolaroo (obviously an Aussie invention) is a light filtering roller shade that installs outdoors, and can be used to screen out incoming light and UV rays on a deck, patio or balcony. Installing one outside an overhang in front a window is also a smart way to keep rooms or outdoor areas sunlit, but cooler, using a perforated breathable fabric that is mildew resistent. Made by the same manufacturer of the Shade Sails (reviewed by Maxwell over at ATNY), who best to learn about heat management but from the sun-scorched folks from the land down under?
