The Eclipse E-Zip motorized exterior screen features a side fabric retention system, which tensions the fabric horizontally between the two side tracks. It is ideal for windy sites, and can be used to cover windows as well as the sides of a patio enclosure. Solar screen fabrics are available with openness factors ranging from 14% to 5%, including Mermet Natte and Satine, and Ferrari Soltis 86 and 92. These are ideal for blocking UV, glare and heat, while maintaining view. We can also provide clear vinyl window panels with solid Ferrari Precontraint 502 borders for stability, which help block wind and hold in heat during cool summer nights as well as in colder times of the year. The E-Zip 5" model is available in widths up to 23' and heights up to 18'. The 4" model is available in widths up to 23' and heights up to 8'. Hardware colors are white, desert sand, and brown. E-Zip is manufactured by Eclipse Shading Systems in the USA. Warranty is for 10 years, and upgradeable to lifetime.
