HeatVision® electrically heated glass

HeatVision® is a special type of treated glass with a transparent electrically conductive coating. Electric current passes through cables on this coating, generating heat so the glass radiates warmth. Power can vary from 150 W to 600 W/m².

The intensity of the heat depends on the final application. The glass can be single laminated glass or integrated in double or triple insulating glass.

Maximum size: 3,210 × 7,000 mm.

Anti-fog and anti-condensation

HeatVision® glass raises the temperature beyond the dew point to prevent condensation. The temperature of the glass is regulated from a simple thermostat up to a home automation system.

Combining functions such as anti-condensation, anti-reflective and lion-proof safety glass is a Thomsa Glass specialty.

Thomsa Glass supplied the electrically heated glass for the new enclosures for the Talapoin monkeys at Apenheul Primate Park in Apeldoorn, and for zoos such as Artis Amsterdam.

Primary heating source in buildings

Electrically heated glass with a surface temperature of 26–28 °C transfers heat by radiation and can bring the room to 20–22 °C. Heat is distributed evenly through the room, which gives high comfort.

Glazing that melts snow

When the snow sensor detects snowflakes, the glass starts heating and melts the snow. The surface stays clear because the heated glass turns the snow into water.

FAQ

What is HeatVision® heated glass for? +
Electrical heated glass has several functions, such as Anti-condensation, anti-fog, comfort heating or even anti-snow by melting down.
How is temperature controlled? +
From a simple thermostat up to full building automation — we design the control and make a powercalculation with our electrical team.
Typical power range? +
Application-dependent; legacy documentation often cites roughly 150–600 W/m². We can give you a customized calculation engineered per use case.
Zoo and marine projects? +
Yes — Electrical heated glass is ideal for enclosures (Zoo) and aquaria. This is a speciality from Thomsa Glass.
Can it be part of an IGU? +
Yes — single laminated or integrated in double/triple insulating glass depending on the thermal request and needs.
Maximum panel size? +
Larger dimensions are often possible, though this depends on capacity and technical feasibility; we recommend verifying the required maximum dimensions and glass configuration before finalizing the drawings.
