Studies have shown that increasing natural light in a building can boost student test scores, reduce patient recovery time, increase employee productivity and improve office atmosphere. When daylight enters a building through glass windows or doors, the sun’s rays simply hit the floor. The 3M Daylight Redirecting Film, however, brings natural light deeper into a building. 3M Daylight Redirecting Film is composed of micro-structured prisms, which redirect up to 80 percent of sunlight towards the ceiling. This illuminates a room and allows buildings to decrease their reliance on artificial lighting. 3M Daylight Redirecting Film is easy to integrate into new or existing windows and requires no additional maintenance or cleaning, unlike other light reflecting strategies. It works at all times of the day, including when sun is at a low angle.
