Panelite’s ClearShade™ high performance exterior glazing allows architects, engineers and building owners to meet daylighting, energy efficiency, user comfort and aesthetic goals in a single product. Most critical for energy efficiency and return on investment, ClearShade™ technology optimizes both daylighting and solar heat control, while most glazing solutions favor one of these goals at the expense of the other. The combined reduction of lighting and HVAC loads results in significant energy and cost savings. The complexity, maintenance and cost of add-ons such as light-shelves and shading devices are eliminated.

What is angular selective glazing?

ClearShade™ is an angular selective technology whose honeycomb structure performs like a series of very small louvers, but in cellular rather than linear form. This structure combined with a proprietary polymer composition provides the unique advantage of dynamic performance – increased solar heat protection at peak hours – without the dramatic reduction in visible light that occurs with other dynamic technologies such as switchable glass.

Benefits of the ClearShade?

1 More light, Better light: Optimized Daylighting
ClearShade™ redirects light rays to transmit up to 70% daylight and substantially diffuse glare, reducing the energy required for electrical lighting and improving user comfort.

2 Less Heat: Solar Heat Control
While most building envelope solutions favor daylighting or solar heat control at the expense of the other, ClearShadeTM addresses both, with a 75% improvement in solar heat gain control over standard IGUs, with Solar Heat Gain Coefficients as low as 0.07 at midday to reduce HVAC requirements and improve energy efficiency.

3 Transparency + Views / User Comfort
ClearShade™ can be specified to provide more or less visual transparency as required by the program or building orientation. The geometry and molecular makeup of the proprietary ClearShadeTM insert diffuse daylight to reduce glare, further improving user experience, comfort and productivity.

Angular selective glazing vs. Low-E only vs. Dynamic Glazing

  • Angular selective glazings are designed to attenuate direct solar radiation, the main source of solar heat gains and glare, while transmitting a significant amount of diffuse skylight.
  • Glazings that use low-e films to achieve solar heat control often do so at the expense of visible light, and this performance is static throughout the day, blocking daylight even when the sun is not at its peak.
  • Dynamic glazings vary over the course of the day to reduce solar heat at peak hours. Technologies such as electro-chromic glass do this by darkening to nearly opaque, blocking both visible light and solar heat.
  • ClearShadeTM is an angular selective technology whose patented honeycomb structure and polymer composition ensure consistent, diffuse daylight throughout the day and the highest level of solar heat control at peak hours.
