> Low emission: PLANITHERM
Planitherm is a type of glass whose surface treatment gives it the property to reflect long-wavelength energy radiation emitted by radiating bodies. As a result it considerably improves the K coefficient of heat transmission, without altering light transmission.

For glazed surfaces where heat losses through the glass need to be reduced to a minimum, using Planitherm glass as a component of a Climalit double glazing system provides exceptional heat insulation. This can be seen in the table below, which compares traditional Climalit double glazing and Climalit double glazing with Planitherm.

The improvement in the K in turn leads to an increase in the temperature of the inner face of the glass, thus reducing—even more than with ordinary Climalit double-glazing—the risk of condensation appearing, and making the area next to the window more comfortable (thanks to a reduction in the “cold wall” effect).

Conditions of use :

Planitherm glass must always be used as an interior component of a Climalit insulating double glazing system, with the treated face in position 3,, in contact with the air chamber.
Common tooling processes are possible, such as cutting, bevelling, etc. and the glass can also be tempered before the layer is applied, to give it the characteristics of tempered glass, or form part of a laminated glass, provided the treated face comes in contact with the air.
