Yes, at AIS Glass, we offer electric car glass variants with special coatings or interlayers that help reduce solar heat gain, thereby improving energy efficiency in EVs. For example, our "IR + UV Shield" family features infrared-absorbent materials dispersed into the PVB interlayer of laminated glass. This helps reduce cabin heat and light load on AC/heating systems. By reducing the amount of heat entering the cabin, the vehicle doesn't have to work as hard to cool down or maintain temperature, which translates into less battery draw in an EV scenario. Also, these coatings help block harmful UV rays and protect interior materials.

"Electrically heated glass and smart glass are distinct features, both of which are relevant in EVs. Electrically heated glass is glass with fine conductive wires or a coating embedded in or applied to the glass/laminate so that when a voltage is applied, the EV glass heats up. At AIS, we have " a Heated Windscreen" in our value-added glass section. The glass has fine metallic wires embedded in the PVB interlayer film, and it is heated by the vehicle battery, which helps melt snow, clear ice, or defog the glass quickly. In an EV, this is useful because using cabin heating to defog or defrost can draw significant power from the battery; a heated windshield can reduce that need. Smart glass is glass that can change its properties via electrical control. At AIS, our "Swytchglas" is one such example. It uses liquid-crystal or suspended-particle technology so that, when a small current is applied, the glass switches from opaque to transparent. In EVs, an equivalent smart glass would allow the cabin to adapt to light/heat conditions, for example, reducing glare or heat from the sun when parked, thereby supporting comfort and efficiency. Thus, in glass for electric vehicles with technologies help reduce reliance on battery-powered heating/cooling, improve occupant comfort and visibility, and support energy-efficient operation."

Electrochromic glass is a type of smart glass that changes its light transmission or tint when an electrical voltage is applied. Typically, the EV glass can shift from a clear state to a tinted/low-transmission state , and hold that state with minimal power. It offers dynamic control of light and heat entering the cabin. For EVs, electrochromic glass could offer benefits such as reducing solar load when parked to conserve battery power, reducing glare for occupants, enhancing privacy, and adding a premium feel. However, its widespread availability in mass-market EVs may still be emerging and given our value-added glass and smart-glass capability, such technology can be adapted.

Yes, glass for electric vehicles can often cost more to replace than standard automotive glass, and several factors drive this cost increase. Here are a few of them:

• Specialised Coatings or Interlayers: If the EV-glass uses enhanced solar-control coatings (IR/UV cut), acoustic interlayers, heated elements or smart features, these add material and processing cost.
• Complex Integration: EVs often have large panoramic roofs, laminated backlites with embedded defoggers or heating elements, or integrated sensors/cameras (ADAS) behind the glass. Such integration means the replacement must match the OEM specification precisely, which drives up the cost of parts and labour.
• Vehicle Architecture and Safety Standards: EVs may have heavier battery packs and different structural design constraints, so the EV glass must meet strict laminating, rigidity, and insulation standards, including thermal isolation and battery safety requirements, which specialised manufacturing adds to costs.

As glass e car often incorporates more advanced technology beyond safety and visibility, the replacement cost reflects those extra features, but the trade-off is better comfort, efficiency, and value for the EV owner. If you need a replacement, choosing a certified product that matches the OEM spec, such as AIS's OEM-standard laminated windscreen, is vital for safety and performance.
