3.9 Caution:The self-adhesive film could be peel off several times and the adhesive will still work.However we don't recommend it for more than 3 times.
3.10 If the self-adhesive film is too big you can cut the film with scissor or knife to the correct size.
3.11 Wipe the cutting edge with a clean cloth with water-free alcohol to avoid short-circuiting caused by rough edge.
3.12 Check the installed smart film in case the bubble or dirt spot peel off the part and reinstall it.
4.Wiring and Sealant
4.1 Connect the bus-bars with wires and wrap the wire joints with insulating tape.
4.2 Use Eva hot melt sealant to fix the wires to the edges of frame and film as designed.
4.3 Peel off the protective liner from the outside of smart film.
4.4 In order to prevent water from entering the self-adhesive film from the edge it is necessary to apply sealant on the edge.GE381 silicone Weather-proofing sealant is our recommended edge sealant.

How Much Do Smart Glass Windows Cost?

The following information is from homeadvisor.com.

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.

    Average Smart Glass Price    

    Average Cost        $100 Per Square Foot    
    High Cost        $150 Per Square Foot    
    Low Cost        $25 Per Square Foot    

Smart Glass Cost Per Square Foot
Smart glass costs $50 to $150 per square foot. Installers usually set rates by the project, offering a lower price per square foot if you replace several windows. One piece runs $125 to $150 per square foot, compared to $50 to $100 per square foot for 100 or more square feet. The cost to install a window with standard glass is $15 to $30 per square foot.

Smart Glass Pricing by Type
Smart glass prices are $50 to $150 per square foot, depending on the total square footage and type:
PDLC: Privacy, frosted, tinting
SPD: Tinting in an instant
Electrochromic: Gradual tinting to a set level

PDLC
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
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
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.

Switchable Glass Prices vs. Smart Window Film
Switchable glass, which may refer to PDLC, SPD or electrochromic products, costs $50 to $150 per square foot and includes all materials and installation. If you want to buy smart film that you can have a pro apply to your existing windows, you’ll pay $25 to $50 per square foot.

Why is PDLC considered to be smart?

The smartness of PDLCs is a result of its ability to change its transparency (technically called the transmittance) when an electrical stimulus is applied to it. This is normally by way of an alternating voltage, which exerts an alternating electric field across the PDLC material.
Nevertheless, the PDLC is only as smart as the control system which stimulates the change, which can be driven by a push button switch, a light sensor, or a building automation system.

What is the structure of PDLC glass?

PDLC smart glass is composed of :
Outermost panels of normal float glass (or sometimes acrylic) sandwiched around:
Inner panels of optically clear PET plastic (polyethylene terephthalate), sandwiched around:
ITO (Indium Tin Oxide) which is a transparent conductor, sandwiched around:
a PDLC core comprised of liquid crystal droplets, suspended in a polymer.
