SageGlass – Why Work With Us?

SageGlass is much more of an experience than a product. We improve how people interact with the built environment and with nature, allowing them to be more comfortable and productive as they go about their day.

Whether in windows, skylights, or curtain walls, glass makes a building beautiful. Glass gives building occupants a visual connection to the outdoors, making them happier, healthier, and more productive. And when dynamic glass like SageGlass prevents glare and excessive heat, it adds even more value.

We are committed to the environment. Our glass significantly reduces the energy required to heat and cool buildings. But that’s only the beginning of our sustainability efforts. We recycle as much waste as we can. We use natural, non-toxic products to maintain our landscapes and clean our buildings. And we volunteer in local cleanup programs.

We are committed to our team members. We focus on providing solid compensation, ample career growth opportunities, positive workplace culture, and work/life balance — it’s all important. And it shows up in the quality of our products.

Finally, we are committed to giving our customers an amazing experience. Our strategy is to put our people first. And we’ve found that team members who are treated well go the extra mile to amaze our customers.

That’s our commitment.








In 1989, John Van Dine founded our company with an ambitious mission: to reinvent glass for buildings.

We embraced the challenge, and today, our electrochromic glass graces buildings all over the world, pleasing the owners, the occupants, and those who pay the energy bills. And we aren’t letting up.

We started in a humble lab in Valley Cottage, NY and a corner of the Rutgers University Center for Ceramic Research.  In 1999, we moved to Minnesota - the Silicon Valley of the window industry – where we established the world’s first Pilot line and production lines for Electrochromic architectural glass.

In 2010, we announced our SAGE triple-pane glazing product, the world’s most energy-efficient window glass. That year, Paris-based Saint-Gobain, the world leader in the habitat and construction markets, invested $80 million in our company. In 2012, Saint-Gobain acquired 100 percent of the company, making SAGE a wholly-owned subsidiary.

In 2012, we opened the largest and most advanced electrochromic glass plant on the planet. Our LEED Gold certified manufacturing facility in Faribault, MN, sets the industry standard for technology, efficiency, and capacity.

We spent the next few years developing a high yield, highly automated production process positioning SAGE to expand globally. The US Department of Energy was an early supporter and tested SageGlass extensively. So did industry fabricators and OEMs. SageGlass has consistently passed or exceeded standards.

In recent years, we have built on our product portfolio, which includes SageGlass®, SageGlass LightZone®, and SageGlass Harmony™. Our newest offering, Harmony, is a unique glazing solution that provides precise glare and daylight control through a natural, seamless in-pane tint transition. If you tour our headquarters, you can experience Harmony’s gradient tinting for yourself.

As the world becomes more connected, so do our products. We offer a turn-key intelligent glass system. The SageGlass Symphony™ control system operates the dynamic glazing, providing intelligent tinting behavior to maximize occupant comfort, well-being, and energy savings.  SageGlass Maestro™, serves as the brains behind the smart system, and holds our proprietary, model-based predictive algorithms.

Every day, our perseverance pays off in small ways. We continue to strive to help the world create more beautiful, energy-efficient buildings that are better for people and the planet. We invite you to become a part of our story.

When it comes to sustainability, we don’t just talk the talk. Our own buildings walk the walk.

SAGE headquarters and manufacturing facilities in Faribault, Minn., are specifically designed to make our Team Members more comfortable and more productive by letting sunlight stream in and providing a view to the outdoors – even for colleagues working on the plant floor. 

In addition to being green, our facilities are pristine. Our manufacturing processes require an environment as clean as a silicon chip plant, and we make sure that standard is never compromised.

When the market’s enthusiasm for SageGlass caused us to outgrow our 60,000-square-foot (5,600-square-meter) building in 2010, our 324,000-square-foot (30,100-square-meter) high-volume manufacturing facility that opened in 2012 became a game-changer in the green building market. This timelapse shows the construction that took place from February through the end of November 2011.

This facility is the world’s largest and most advanced dynamic glass manufacturing plant, able to produce SageGlass in high volumes and in large commercial architectural sizes at an affordable cost. We invested in the world’s best available manufacturing technologies to produce a dynamic glass product of uncompromising quality and reliability. The plant houses the world’s largest thin-film coating system for glass production, and is currently undergoing further rounds of expansion.

Our HVM plant has LEED Silver certification . We sourced as many local building materials as possible. An unusually large number of windows and skylights throughout both the offices and the manufacturing facility provide natural daylight and offset the need for conventional electric lighting. The HVAC and chilled water systems use natural cooling from outside air. An innovative hot water reclamation system recycles heat back into the building. Waste- and rain-water reclamation systems conserve water usage.  With these and other sustainable features, the energy performance of the new SAGE facility is projected to be 28 percent better than the ASHRAE 90.1 baseline – a key national energy standard for commercial buildings today.

At SAGE, we are on a mission to improve the world – making buildings more energy efficient and more comfortable, while reducing the carbon footprint.  That mission is not easy.  When we started our journey, the glass industry had spent almost half a billion dollars developing switchable glass for buildings with no products in production.  Since us, the Silicon Valley has spent several billion dollars trying to catch us.  Being on the cutting edge of high technology requires great people, working in a great environment. 

At SAGE we need the best people, from all cultures.  Today, SAGE is highly culturally diverse, with 26 or more mother-tongue languages spoken at SAGE.  Cutting edge technology has attracted great people from all over the world.  Gender diversity at SAGE, however, has been an intentional journey.  Not that many years ago, SAGE professional ranks were not gender diverse at all, with only 7% of our staff female.  We are a STEM business, and had not affectively recruited women in science, leadership and technology.  This was not congruent with our values – to be successful, we needed to attract not just the best men, but also the best women!

In the past 5 years, SAGE has grown to over 33% female in our professional ranks, double the rates of many Silicon valley firms.  In STEM technology businesses this is best-in-class performance, but we’re not done.  We don’t believe it is right to hide behind the STEM excuse – we want to drive change.  We desire to reach 40% in the near future, and ultimately have our Team Member census reflect the gender balance of society as a whole.  And gender balance is not a quota here – that would be dishonoring to our existing female executives, scientists, engineers and other professionals. To work here, you’ve got to be smart, motivated and passionate about making the world a better place.  But there is a lot of opportunity here – for both men and women!

    I have been working at SageGlass full-time (More than 8 years)


    This company has given me a lot of opportunities for career growth and training. I've worked for SAGE for many years, and expect to be with them for many more!


    Sometimes there are difficulties working for a large corporation. New policies and changes can be difficult to swallow sometimes, but that's probably just because I don't do well with change.

    Advice to Management

    Keep doing what you're doing. You have made this company a place where everyone is friendly and you've proven time and time again that people come first. Thank you!
