Patio Enclosures. The manufacturer's entire line of sunrooms is now available with SunClean self-cleaning glass. A coating fused to the glass uses UV rays to create a sheeting action that loosens and breaks down dirt on the window's exterior. Rain or a light water spray rinses dirt away, says the maker. The glass is available in both standard and low-E versions. (800) 480-1966. www.patioenclosures.com.
