Features and Benefits of Switchable Privacy Glass

Features and Benefits

The PDLC switchable privacy glass application can be used in many innovative ways. Here is a summary of some of the main features and benefits of using PDLC switchable privacy glass:

Standards and Codes

While industry codes do not regulate directly smart glass product per se, smart glass does meet a number of federal safety and regulatory codes due to the nature of its fabrication. Among the most important are the following:

Privacy and Occupant Comfort

PDLC switchable privacy glass can be a smart choice to maximize privacy and occupant comfort in interior commercial spaces. For example, in the private mode, there is natural daylight coming through, which is good for mode settings in enclosed office spaces.

Let’s take a look at some of the many broad applications and settings where PDLC switchable glass can be used to serve both function and design purposes.

Broad Applications

Privacy: Privacy or transparency can be obtained at a moment’s notice in both exterior and interior installations. Glass with PDLC film can transform the functionality and appearance of:

(Note: PDLC films also offers privacy options for private homes, especially where street views or neighboring homes are close at hand.)

Design: Switchable glass eliminates the need for dust-collecting draperies, shutters, and blinds, an option that designers may find very attractive.

Daylighting: To daylight an interior effectively, harsh sunlight must be moderated to reduce glare and spread more even illumination at comfortable levels. PDLC film-enabled windows, skylights, and glazed doors can be switched to translucent mode at peak hours of sunlight to cut light levels roughly in half and scatter the light, providing a diffuse source that illuminates more of the room with less glare.

Safety and Security: PDLC film makes switchable glass that is similar in construction and functionality to safety glass. Properly applied, glass panes laminated with PDLC film meet safety glass standards and can be used in security and hurricane-resistant window applications.

Temperature Control: PDLC film can reduce transmission of infrared radiation on demand. Switching a PDLC film window to its translucent state during peak sunlight can help control interior temperature and reduce the load on air-conditioning systems, lowering energy costs.

Multifunctional: Glass with PDLC film can substitute for a whiteboard, maximizing the utility of a conference room, classroom, or consultation room. It also performs excellently as a rear-projection screen for videos, slideshows, or almost any projected image.

Interior Applications

PDLC switchable glass can provide flexible use of space with privacy on demand (when needed). Some of the interior applications where this technology can be used include:

Sustainability and Energy Use Reduction with PDLC Technology

Switchable privacy glass is a sustainable product that can lower energy consumption and energy costs by improving the use of natural daylighting, lowering energy use for illumination, and reducing solar heat-gain, thereby reducing air-conditioning demands.

While it can vary by manufacturer, most panels have very low power requirements. The glass draws less than 0.5 watts/square foot. By contrast, a typical solar (photovoltaic) panel installed in North America has an average output of about 10 watts/square foot, meaning that one single 25-inch by 54-inch solar panel could potentially offset the power usage of three large 72-inch by 120-inch windows.

Industry leaders are aware of the importance of limiting their carbon footprint and work proactively with suppliers and application partners to ensure that glass/film products are eco-friendly. The main ingredient of PDLC panels is glass, a material with a well-established and widespread recycling infrastructure. Recycled glass is a regular component of modern glassmaking and significantly lowers the CO2 emissions associated with manufacture.

Additionally, panels can be reusable; that is, glazing can be removed from its original installation and reused, fully functionally, in another building.

Among the key sustainability and energy-savings benefits of switchable privacy glass with PDLC technology are:
