Transparent nano coating TG® and its electrons in action

ThermoGlass® technology uses a transparent nano coating on the glass surface to transform electrical energy into radiant heat. The nano coating, which is thinner than 1/50 of the thickness of a human hair, is applied to the surface of incandescent glass by a long-term proven manufacturing process which guarantees its long lifetime.

Transparent nano coating is laser-treated with patented technique, in order to regulate the flow of electric current and thus precisely set the required power and temperature of the radiant glass.

The supply of electrical energy to the conductive nano coating is ensured by means of two electrodes, which are applied in the form of a special powder mixture of metals. The nano coating is heated by the flow of electric current and transforms electric energy into pleasant radiant heat.

The result is transparent ThermoGlass® heating glass, that emits infrared radiation in the wavelength range of 2-13 microns - this thermal radiation interval is ideal for humans and their perception of thermal comfort.

How to use ThermoGlass® heating glasses

Visually, the TG® heating glass is no different from conventional glass, but its features offer unique  advantages and applications in the maintenance-free comfort heating industry.

TG® infrared radiant IGUs for windows

Glazing with a TG® nano-coating is used as a part of infrared insulating double or triple glazing (IGU) for wide use in interior heating or as a safety bonded infrared glass Triplex (ESG / VSG) eg for defrosting snow on roof glazing.

Infrared radiant VSG Triplex TG®

Infrared radiant VSG Triplex TG® heating glasses can be used as a double-sided heating structure in the interior (glass partitions, interior door glass panels).

Another option is to install Triplex TG® glass in an interior position in insulating double or triple glazing where it serves as a safety glass.

The surface temperature of Triplex TG® glasses is the same as for conventional TG® glasses.

Comparison of technical parameters

The monitored factors with ThermoGlass® double glazing and triple glazing: 

Ug = heat transmission coefficient      /      g = solar factor - indicates the total transmission of solar energy through the glazing      /       LT = light transmission - rate of visible light coming through the glazing

+ Higher light transmission

+ Lower purchase price  

+ Lighter

- Higher heat loss

+ Lower heat loss  

- Higher purchase price  

- Heavier

- Lower light transmission
