SageGlass is the leader in dynamic glass. However, there are several different technologies in the dynamic glass market and it is important to understand how they differ from each other.
Dynamic glass can be categorised in one of two ways: controllable and non-controllable. The difference is also sometimes referred to as “active” versus “passive.” As the name implies, the controllable technologies are operable by people. In some cases they can be integrated with a building’s automation system to tint and clear on demand. The non-controllable technologies change their state in response to something happening in their environment. For example, thermochromic technology changes its coloration when it reaches a certain temperature.
What SageGlass is:
SageGlass is electrochromic technology, which is controllable, so it can be tinted or cleared by the user (or building system) on demand. Its purpose is solar control since it modulates both incoming light and heat from the sun. SageGlass is not intended to provide privacy. That is an entirely different product with a completely different purpose. Privacy glass is used to block the view, so it’s often found in interior areas such as board rooms and bathrooms. SageGlass is designed to block unwanted sunlight, heat and glare – but to continuously preserve the view.
At SAGE, we specialize only in electrochromic glazing. Our product is branded as SageGlass.
What SageGlass is not:
Thermochromic technology modulates the amount of light coming through the glass in response to changing environmental temperatures (such as sunlight exposure, air temperature and wind velocity). People don’t have control over the glass.
Photochromic technology modulates the amount of light coming through the glass in response to changing light levels outside (think of transition sunglasses). People don’t have control over the glass.
Suspended particle devices tint and clear in a manner that looks like electrochromics but at the micro-level it’s actually very different. It’s “organic” technology, meaning there are polymer-based materials sandwiched in the glass. Any time you expose organic materials to things like intense sunlight, UV and infrared heat, you have to worry about durability. Also, the technology significantly underperforms SageGlass in both light control and energy reduction.
Privacy glass can be changed from clear to an opaque milky-white color that you can’t see through.
