Heated Glass

How it works, where to specify it and how it can enhance a home.

Heated glass is a modern glazing technology available from IQ Glass. An invisible heat source that can be specified in almost any glazing system, the specialised glass can be used as a sole heat source for a glazed space, or as a way to effectively eliminate the risk of condensation build up.

How does it work?

The technical solution works by applying a transparent metal oxide coating to the glass unit. An electric current can then be passed through the coating via buzz bars at the head and base of the glass installation. In keeping with the invisible solution, these buzz bars are concealed within the glass construction.

This coating used by IQ is considered a semi conductive material, therefore, when electricity is passed through the coating it generates a radiant heat source. Due to the fact that no trench works, blow heaters or floor grates are required with this technique, heated glass is considered the most minimal of all heating solutions.

Where can I use it?

Heated glass can be specified in a wide range of applications, including within frameless structural glazing. As well as utilising heated glass within window and door designs, entire walls of frameless glass can be specified using heated glass.

When using heated glass as the sole heat source in a living space, the amount of heated glass required to affectively heat the room is calculated based on the square metre floor space. As a general rule, 20% of the floor space will need to use heated glass. Thanks to the coating being completely invisible, heated glass can be used in conjunction with other panes of glass, without a visible difference.

Over the years, heated glass has become a popular method of reducing condensation build up. Be it in spas, swimming pool areas or kitchens, heated glass will eliminate the condensation in high humidity areas to reveal crisp, clear glass installations.

Another great use for heated glass is snow or ice removal. If heated glass is specified for this application, IQ Glass will design the system so that the heat radiates externally. A smart control system can also be used, switching the system on automatically if the temperature reaches a certain level.

Heating Control

The glass can be heated to a surface temperature of 20 to 60 degrees when using heated glass. The temperature can quickly reach 60 degrees, in a short time of just 20 minutes, thanks to the low thermal mass. The typical surface temperature for a highly glazed living space would be between 20 and 30 degrees, creating a comfortable living temperature.

Temperature sensors can be used within the glass unit, working in conjunction with a room thermostat to regulate the temperature. The glass could also be controlled via a centralised control system, as it can be set up to work as part of a larger electrical heating system.

This solution is perfect for smart home technology systems and can be integrated to work alongside any home automation systems, including those available from IndigoZest. Integrating the heated glazing within a smart home system offers enhanced functionality, in a way that suits each client’s individual needs.
