These MotionScreens from Universal Screen block the unwanted bugs while allowing complete visibility. We used TuffScreen No-See-Um screen for the north facing openings and SunTex 95 for the east and west openings to provide heat control. This customer added a storm door for easy access to the pool for him and the yard for the dogs. And in case you accidently lower the shades with a chair in the way, the Somfy Maestra motors include built-in obsticle detection.
