SGG PLANITHERM® 1.3/1.3T is the high transmittance range of high performance low-emissivity products, incorporating the very latest advancements in thermally insulating glass coating technology.

Renowned for its extremely neutral appearance, SGG PLANITHERM very effectively reflects long-wave heat radiation back into a room, thereby minimizing heat loss  through a window while also maximizing solar heat gain and natural light transmission.

The SGG PLANITHERM coating is generally positioned on face 2 of a double glazed unit though it is possible to place the coating on face 3. And it can also be associated with other solar control coatings (coated on face 2) when PLANITHERM coating place on face 3.

The high transmission and great thermal performance allow architects and specifiers to utilize large areas of glazing and create bright, and especially is ideal suitable for application in north regions of China.


Product Application

SGG PLANITHERM® 1.3T is designed for use in all double glazing applications, in all frame types for both new-build and replacement markets:

-  windows and skylights in residential buildings and private domestic housing

-  conservatories and patio doors

-  windows and façades of non-residential buildings

-  freezer



A double-glazed unit incorporating SGG PLANITHERM is more thermally efficient than an ordinary double-glazed unit and offers significantly better thermal insulation compared to traditional hard coated Low-E products:

-  Considerable reductions in heating bills

-  Reduces condensation on the inner pane

-  Improved comfort with less drafts and cold spots near glazed areas

-  Environmentally friendly solution, given the lower CO2 emissions associated with reduced energy consumption

-  Facilitates compliance with building regulations for a wider range of frame designs

-  Neutral Appearance

House windows - Day-light for House windows

The high transparent glass or larger sizes of the windows enable a better illumination of your home indoor space, which has a positive impact on your health: Several international scientific studies have shown the healthy effect of natural day-lighting on human-beings.


House windows - Energy Saving For House windows

Installing energy efficient windows with SGG's high performance Low-E or solar control glass can save your energy bills compared to traditional windows and frames.

Our own research has shown that many homeowners are unaware of the performance differences between different types of window glass, instead assuming that all double glazing is equally energy efficient. In reality, there are significant differences in performance with the type of glass used being key.



House windows - Thermal Insulation for House windows

Thermally insulating glass (also known as low-emissivity or low-E glass) usually forms the inner pane of an Insulating Glass Unit (IGU).The glass has a transparent metallic coating that reflects heat from radiators or fires back into the room, rather than allowing it to escape through the windows. At the same time it allows free heat and light from the sun (known as passive solar heat gain) to pass through the glass, warming your home and further contributing to the energy efficiency of your windows.
