Daylight – delivered
with truer color
3M™ Specular Film on Metal is better than reflective aluminum for tubular skylights and tubular daylighting systems
Higher specular reflectivity delivers maximum daylight through tubular skylights and daylighting systems.
3M™ Specular Film on Metal delivers more daylight‚ farther‚ with truer colors and superior aesthetics compared to enhanced silver coated reflective aluminum (ESA). The reason: it possesses more reflectivity‚ both total and — even more important — specular.
is a measure of useful light‚ moving forward‚ through the daylight tube; 3M specular film on metal offers a greater than 2% higher specular reflectivity resulting in increased product performance in tubular skylights.
measures light that moves in all directions — including non-useful‚ back-scattered light.
A small amount of increased specular reflectivity yields greater performance in daylighting systems and tubular skylights.
Delivers the same amount of daylight up to 250%* farther
The physics of light transfer efficiency (LTE) mean that even a seemingly small increase in specular reflectivity — even just 2% more — enables daylight to travel much farther down a tube with less light loss.
3M specular film on metal allows equal light levels to travel up to 250% farther versus silver coated reflective aluminum.
Based on a 10” diameter x 10’ in length daylight tube with an incidence sun angle of 25 degrees from the horizon.
Specular Light that’s Significantly Brighter:
3M specular film on metal has significantly superior daylight transfer efficiency (LTE) compared to enhanced silver coated reflective aluminum‚ resulting in much greater daylight output.
It’s literally a brighter idea‚ providing a 107% increase in daylight output down a 10’ long × 10” diameter daylight tube with an incidence sun angle of 25 degrees from the horizon.
Quality of Light that’s Truer:
Because 3M specular film on metal is a clear‚ colorless optical film‚ the quality of daylight it delivers is full visible spectrum; it reflects the color of sunlight from outside‚ resulting in truer‚ more natural colors inside.
There are many benefits to using 3M™ Specular Film on Metal in tubular skylights and daylighting systems.
By moving more and better daylight deeper within a building‚ 3M specular film on metal can help reduce lighting costs and increase occupant satisfaction. If you have questions or wish to speak to a representative‚ please call us at 1-888-650-3497 or contact us.
Daylighting systems — using daylight from the sun — is the original green building practice that allows for up to 100% off-grid lighting during the day.
Because 3M™ Specular Film on Metal moves daylight farther with more brightness compared to enhanced silver coated reflective aluminum‚ it opens up many more interior spaces to the opportunities of daylighting.
