3M Daylight Redirecting Film increases natural light indoors

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. 

The problem is how we bring more natural light inside.

There’s a new solution: 3M’s Daylight Redirecting Film, which brings natural light deeper into a building. The window film is the second generation of the Daylight Redirecting Film from 3M. Previously, redirecting daylight and diffusing daylight required a two-step process, but the new Daylight Redirecting Film does both in one easy step.

When daylight enters a building through glass windows or doors, the sun’s rays simply hit the floor. 3M Daylight Redirecting Film is made up of micro-structured prisms that redirect up to 80 percent of the incoming sunlight toward the ceiling. This illuminates a room, decreasing reliance on artificial light and lowering electricity bills. The film also diffuses the light, reducing heat and glare caused by intense sunlight.

3M Daylight Redirecting Film can be easy to integrated 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.

The video below provides a look at how the solution works.
