2021 Notice: Material Prices are Surging

Demand for windows has grown over the past year. And, as a result, manufacturers are increasing materials prices. Prices have gone up 5% to 10% this year, and many parts of the country are experiencing long delivery times. If you're planning a window installation or replacement project, we recommend starting as early as possible in the season, preparing for potential price fluctuations, and allowing extra time to order materials.

Smart Glass Cost

Smart glass costs $25 to $150 per square foot. Glass with film pre-installed is $50 to $150 per square foot, compared to $25 to $50 per square foot for the film alone. Price depends on the total square footage, with single units running up to $50 per square foot more than you’d pay to install several.

Smart glass makes it easy to change the look of your windows in an instant. You can make them completely opaque for privacy or add tinting to shade a home and cut your energy consumption. There are a few different types with unique benefits, so you’ll need to choose the one that’s right for you. Keep these cost factors in mind as you browse.

PDLC glass tends to be the most expensive option. It offers privacy at the touch of a button, making it ideal for indoor and outdoor applications. This technology is the only type that turns completely opaque, which means you can use it for bathrooms, showers, private offices and more. You can also turn it into a television projector.

PDLC has crystals that are both liquid and solid, similar to what you’d get in an LCD television or monitor. It has a lot of names, including:

  • Electric privacy glass
  • LCD glass
  • Electric frosted glass

The crystals are inactive when turned off, which makes the glass appear frosted or dark. Once you turn it on, the window is completely clear or dimmable.


SPD glass is the middle-of-the road cost option, with pricing a little lower than PDLC. This type allows you to select the level of tinting from minimally shading to full darkness, although it can’t provide complete privacy. Its heat-blocking features make it a great choice for exterior windows. You can also use it for any interior room that needs additional darkness in daytime, like a home theater or child’s bedroom.

SPD suspends particles in a liquid. When you turn on the device, it brings those particles in line and allows you to the control the level of tinting. Like PDLC, these windows are dimmable.


Electrochromic glass is the cheapest option. This type allows you to change the tinting over the course of a few minutes. It uses ions to force particles to the inside or outside of the window, making the material clear or tinted. Those particles stay in position until you use the control to move them again.

Electrochromic glass is similar to photochromic or thermochromic tinting, but it’s important to understand the difference. Photochromic and thermochromic products, like Transitions eyeglass lenses, tint based on light or heat. They don’t require energy to change, but you can’t control them. Electrochromic options use energy comparable to a single LED lightbulb, and make it easy to change whenever you want.

If you’re replacing your windows, you’ll need to factor in the weight and size of the glass too. When you call window installers near you for a quote, be sure to ask if they can install the type you’re looking for.
