3M™ Daylight Redirecting Film is a simple, effective daylighting solution which comfortably brings natural light deeper into buildings.

3M™ Daylight Redirecting Film is designed to move excess light close to the window and redirect it deeper into the building to increase the daylighting penetration. Bringing natural light deeper into the building helps provide the many benefits of natural light for more occupants as well as helping reduce the need for artificial lighting which can save energy.

In addition, 3M Daylight Redirecting Film:

Reduces glare and discomfort caused by direct sunlight on occupants

Redirects natural light as much as 40 ft. or more into the building

Extends daylight zone up to 8 ft. into the interior for every 1 ft. of treated window

Can provide up to 52% lighting energy savings compared to baseline usage

Can provide savings of up to 1.5 kwh/sq.ft. of floor area

Simple, effective, daylighting solution.

Compared to existing light reflecting strategies, 3M Daylight Redirecting Film is easily integrated into new or existing windows.

It requires no extra hardware or infrastructure, and little to no additional maintenance or special cleaning. It works at all times of the day, even when the sun is at a low angle. Plus, it’s more cost effective than many existing daylighting solutions

Daylighting diagram 1

3M™ Daylight Redirecting Film is installed in the upper portion of the window.

Daylighting diagram 2

Daylight is redirected upwards toward the ceiling, allowing natural light to penetrate deeper into the building.

Daylighting diagram 3

Made of micro-structured prisms, the film optically redirects over 80% of daylight upward and diffuses it for even distribution.

Clear Glass Window

When Shades Are Open

Direct sunlight can beam into the space at low angles, causing glare and discomfort.

Image

When Shades Are Closed

Shades are closed to block uncomfortable direct sunlight, which also decreases natural light in the space.

3M™ Daylight Redirecting Film

Image

When Shades Are Open

The light from the upper glass is redirected to the ceiling, increasing natural light and decreasing glare in the space caused by direct sunlight.

Image

When Shades Are Closed

Even when the vision glass shades are drawn, natural light continues to penetrate into the space through the clerestory glass with 3M Daylight Redirecting Film.

Optimizing natural light is good for business.

Installing 3M™ Daylight Redirecting Film provides a better experience for everyone.
