The use of thermal glazing is a consequence of continuous technical progress and the desire of the modern building industry to minimise the need for heating, with the proper insulation of buildings playing an increasingly important role. Modern energy management involves, above all, the reduction of energy losses and the controlled use of free solar energy.​​​​​​​Thermal glazing is manufactured from low-emissivity soft-coated glass, which is produced using an 'off line' process, i.e. a metallic coating is applied to the glass pane outside the float glass production line. The emission value of this coating is several times lower than that of glass. Single chamber glass pane constructed with this type of glass allows excellent parameters to be achieved: high daylight transmittance, maximum low U value (heat transfer coefficient), highest transparency, colour neutrality and optimum energy transmittance (glass pane with a space between the panes infilled with noble gas (argon) achieves a U value of 1.0 [W/(m² K)].
