Stay cooler on hot, sunny days by reflecting the sun's heat with advanced radiant barrier technology from Alchemi Labs. The reflective panels block 99.8% of UV rays and reflect up to 80% of the sun's heat rays. The same technology is used by NASA to protect astronauts from solar radiation in space.
