Solar Specifications
Your guide to understanding the benefits and features of our solar window film products. Explore how our innovative solutions can reduce heat, glare, and UV radiation, while improving energy efficiency and comfort in any environment. Let us illuminate the path to a brighter, more sustainable future for your space.
See the terminology below for our solar specification films.
VLR % - VISIBLE LIGHT REFLECTION
The percentage of total visible light that is reflected out by a glazing system. A glazing system with a high VLR means that most of the daylight is not passing through the window.
​
VLT % - VISIBLE LIGHT TRANSMITTED
The percentage of total visible solar energy that is allowed to pass through a glazing system - the higher the percentage, the more light will pass through the film.
​
UV % - ULTRAVIOLET
The percentage of how much ultraviolet solar energy is rejected / prevented from passing though the film.
​
IRR % - INFRARED REJECTED
The total amount of infrared rays rejected by the film - the higher the number, the higher the infrared rays rejected.
​
SA % - SOLAR ABSORBSTION
The portion of total solar energy that is neither transmitted nor reflected by the film.
​
U F - U FACTOR (MILD WINTER)
U-factor indicates the heat energy level, independent of the sun's radiant energy, that passes through a glass and window film a lower u-factor number means better heat retention inside a building in cold weather - it is also good for keeping buildings & cars cool in hot weather.
​
E - EMISSIVITY
Emissivity is the insulating quality of a film - low emissivity films allow very little heat to pass through the material where they can reflect a large portion of the heat generated on a building's interior back inside (good for colder climates). In warmer climates, they can prevent outdoor heat from getting inside through the windows.
​
SCE - SHADING CO-EFFICIENT
The ratio of heat passing through the film the lower the shading coefficient number, the better the shading quality of the film.
​
SHGC - SOLAR HEAT GAIN CO-EFFICIENCY
This is similar to the shading co-efficiency except that this also takes into account the energy that is -re-radiated back in to the room from the glass the lower the SHGC, the better the solar control properties of the film will be.
​
GR % - GLARE REDUCTION
The percentage by which visible light transmission is reduced by the addition of a filtering material - the greater this number, the better in terms of reducing harsh or excessive light.
​
TSER % - TOTAL ENERGY REJECTED
The percent of solar energy rejected by a film. This value equals solar reflectance plus the part of solar absorption that is both re-radiated and conducted / convected outwardly the higher this number, the better.
