ItSwitchable glass, or smart glass windows, are an innovative window technology that is becoming popular with both homeowners and businesses. Smart windows can improve privacy, reduce glare, and improve energy efficiency. When the technology is becoming popular, the first questions asked are “Are they worth the cost?. In this owner’s guide, we look at smart glass technology, benefits, drawbacks, pricing, and smart glass windows as an investment.
What Is Smart Glass Windows?
Smart glass can also be referred to as switchable glass and it is a type of windows that is controlled electrically, via a remote, or through an automation system. It can be used to improve or alter transparency and opacity of glass. Smart glasses can improve energy efficiency, help control glare, and help privacy. Smart glass technology is a great modern, minimalist substitute for older technologies like curtains, shades, or blinds. It changes instantly between opaque and transparent states, which give with dynamic control to the environment they are in. This can include cars, offices, or homes.
Smart Glass Technology Types
Smart glass technologies can be divided into two categories: PDLC (Polymer Dispersed Liquid Crystal) glass, and electrochromic glass. Each type has different smart technologies and features to suit diverse applications.
Electrochromic Glass
When an electric current is applied to electrochromic glass, it tints gradually. This process is great for reducing the amount of heat and glare that enter a room, thus helping to enhance energy efficiency in the cooling of a room. Because of this, the glass is great for commercial and residential applications. Because of its subtle and gradual change in transparency, it is often used in a variety of construction applications.
PDLC (Polymer Dispersed Liquid Crystal) Glass
PDLC glass is a type of switchable glass, which means it can be clear and opaque. This process is instantaneous and great for applications where the need for privacy is urgent, such as a bathroom, meeting room, or home office. PDLC is a great option for applications that require technologies to control transparency on demand and provide a quicker electrochromic glass response.
How Smart Glass Windows Function
The way smart glass windows operate is through an electrical current that changes the property of glass by altering how much light can pass through it. Different types of smart glass technologies can make the glass turn either clear or opaque. Because the glass can switch to opaque, it is unnecessary to use window coverings like curtains or blinds. This creates a less cluttered appearance and provides a clean, minimalist design.
Smart glass windows can also connect with home automation systems. Because smart glass can integrate anywhere home automation is used, smart glass can be controlled with apps and voice commands.
Benefits include:
- Ability to control privacy: Block outside views and light to create privacy, making these windows ideal for areas that require privacy.
- Energy Efficiency: Improved cooling efficiency by blocking excess sunlight.
Advantages of Smart Glass Windows

Smart glass costs more than traditional windows, so a balanced evaluation is needed.
- Smart glass windows most certainly costs more than traditional double pane windows, however, they can produce savings by cutting down the need to cover windows with curtains or drapes or even save on energy costs from the windows.
- A lack of power outages can help resolve concerns of electrical dependency, however, automatic switching due to smart home systems should resolve this issue.
- Window smart glass systems can make the limitations of quick malfunction and repairs frustrating. Warranty and maintenance constraints shouldn’t be overlooked before the smart glass is installed.
Smart Glass Window Pricing
The size of glass, types of technology, and installation challenges can all affect the price of smart glass windows.
Typical costs:
- Basic smart glass can average from $50 to $150 for each square foot and can be more expensive than double pane traditional glass windows.
- Electrochromic Glass: because of its gradual tinting abilities it generally falls on the higher end of the pricing spectrum.
- PDLC Glass: this type of glass may be more affordable if instant privacy is needed.
The initial higher expense of smart glass windows can be offset by savings in the future that may also reduce the expense of coverings like blinds and shades that can be hundreds of dollars to install and maintain.
Are Smart Glass Windows Energy Efficient
Yes smart glass windows can reduce solar heat gain, which can help stabilize indoor temperatures. This means less reliance on a/c and heating units. In hotter climates smart glass lowers cooling costs and energy bills because it blocks heat.
Potential Energy Savings %
The type of glass, climate, and location all cause variations in energy savings. Smart glass can reduce cooling demands by 25% according to some studies. This is significant for homes and offices in warm climates.
