In addition to our interior sunshades, we also offer a rollup shade for use outdoors. It is perfect for use on patios as well as problem windows. Basically, the exterior shade is identical to our interior shades in design but includes anchoring hardware to secure the shade in the event of light winds. The obvious difference between the interior and exterior rollups is the material. Outside shades are made with a durable fabric called Suntex, which is a PVC coated material originally used in lawn furniture cushions and umbrellas. Suntex is also widely used as a fix-framed light and heat barrier on windows. Grab a free sample on our sample page.
