A pane is an extremely important element of a window. Not only due to its obvious function but also due to it surface area.  A pane constitutes approximately 70% of the window surface area.

Most popular are windowpanes made of heat-absorbing glass characterised by improved thermal insulation parameters (U=1.0 W/m2K in line with PN-EN 674). Such a glazing unit is filled with argon and one of the panes is a Thermofloat pane with an invisible coating made of a combination of noble metals (the so-called low emissivity coating).

Using quality panes translates into savings (due to reduced heating costs) but also slows down wall paint fading process (due to reduced permeability of UV radiation). Additionally, such windowpanes make occupants feel better thanks to improved insolation (high transparency).

In terms of sunlight permeability windowpanes may be divided into those made of heat-absorbing and hest-reflecting glass:

• heat-absorption glass - tinted blue, brown, gray or green. Reduces penetration of solar energy into the room.
• heat-reflecting glass - body tinted blue, brown, gray, green or colourless. In order to achieve the reflection effect, reduce penetration of solar energy into the room as well as control the amount of light these panes are coated with metallic oxide.
