The affordable shading fabric. SunTex® is manufactured for the primary purpose of reducing solar heat gain in the summer and reducing interior heat loss in the winter. SunTex® absorbs and dissipates up to 70% of the sun's heat and glare before it reaches the window, while also performing as an insect screen. This shading fabric is easily installed on any type and size of window, and it works whether windows are open or closed. SunTex® 70 is available in only BLACK fabric colors.
