It is time to change our expectations of daylighting. Time for something that sets new standards in quality and performance. Something permanent.

Introducing Solera® insulated glass daylighting units.

Solera® was designed to deliver the ultimate in visual, acoustic, and thermal comfort for building occupants by using real glass.

Solera® insulated glass daylighting units seamlessly integrate with any standard curtain wall or glass framing system.

This product allows specifiers to precisely configure and control light diffusion, visible light transmittance, and solar heat gain properties while achieving superior acoustic performance and thermal insulation ranging from R2.2 to R25. Ideal for new construction and renovations, Solera® is UV-stable and includes a warranty against color shift for greater peace-of-mind.

Improving the Places Where People Gather

Solera® brings controlled, usable light to the places where people gather. It fills small and large spaces with high-quality, diffused light that is glare-free, evenly-distributed, comfortable, and consistent throughout.

Some of the most common spaces where Solera® shines include:

  • Libraries
  • Lobbies
  • Healthcare Facilities
  • Terminals
  • Offices/Classrooms
  • Galleries & Exhibits
  • Atriums
  • Indoor Sports Facilities

Light Diffusing Power from Advanced Glazings. Experience Superior Daylighting You Can See and Feel.

Solera® is the only daylighting system with Light Diffusing Power – a proprietary measurement and rating system from Advanced Glazings that allows building designers to compare the light diffusing ability of various glasses and coatings.

The results of Light Diffusing Power testing show that controlled daylight is the only daylight worth having. Solera® ensures this control – glare-free, evenly-distributed, comfortable, and consistent daylight for the ultimate in usable spaces.

Standard Vision Glass
  • Significantly lower light diffusion power
  • Little to no light dispersion
  • Creates shadows and dark spots due to sun position
  • Persistent glare

  • Extremely high light diffusion power
  • Consistent light dispersion throughout irregular spaces
  • Reduction in shadows, regardless of sun position

Selecting the right glazing has always been critical to the success of a daylighting project. But it hasn't always been easy. It used to require poring over large, multi-dimensional sets of data that only an optics expert or computer simulation program could translate. Until now.

Light Diffusing Power from Advanced Glazings is a simple rating system that allows a designer to easily compare the performance of light diffusing glazings, and differentiate them to make the right daylighting choice.

The glazing sample is illuminated by a quartz halogen spotlight, at an incidence of 45 degrees. A light meter measures the radiant intensity leaving the aperture in the mask that covers the back of the sample. The measurement is repeated over a range of angles from -85 to +85 and the results are recorded. (Measurements at exactly 90° not physically possible).

While products such as Acid Etched Glass and White Laminated Glass can be classified as "Narrow Angle Light Diffusers," Solera® – with its exceptional light diffusion – is classified as a "Wide Angle Light Diffuser." For a technical brief on the LDP setup and experiment, contact us today.

Transparent InsolCore®
Transparent InsolCore®

Provides an R5 thermal insulation (U-Value of 0.2 Btu/hr·ft2·℉) and can achieve up to 55% VLT when used in an IGU configuration.

* Not available in Solera L model.

Lumira® Aerogel

Meet strict energy codes and dramatically improve thermal performance up to R25 by including Aerogel, and virtually eliminate the trade-off between insulation and natural light.

The Best of Both Worlds: Unsurpassed Daylight and Insulation with Aerogel

The traditional compromise between natural light and insulation is over.

Diffusion of light, heat, sound, and moisture through Lumira® Aerogel

Solera® insulated glass daylighting units, with aerogel, simultaneously provide effective daylighting and insulation.

This dual performance benefit is achieved by harnessing the exclusive properties of aerogel – the lightest and most effective insulating materials in the world. When integrated into Solera®, aerogel offers:

  • Unsurpassed thermal insulation
    • R-value of 8 per inch
    • U-value of .64W/m2K per 25mm
  • Reduced solar heat gain/loss
  • Increased natural light transmission
    • 75% per 3/8", 80% per cm
  • Decreased energy consumption
    • Heat, A/C, Lighting, Ventilation, Carbon Emissions
  • Superior, glare-free light diffusion
  • Unmatched moisture resistance
    • 100% hydrophobic
  • Improved acoustic performance
  • Exceptional color stability and insulation performance

Aerogel resists the transfer of heat, making it a great insulator

More About Aerogel

Cabot's aerogel is among the lightest and most effective insulating materials in the world. Cabot's aerogel, formerly Nanogel®, is a solid which consists largely of air (>90%) contained in a structure with pore sizes less than the mean free path of air molecules, which severely inhibits heat transfer through the material, enabling world-class performance. Cabot produces aerogel at its state of the art manufacturing facility located near Frankfurt, Germany where it began commercial production in 2003.
