Triple insulation is a long-standing standard in passive houses, but also in conventional new construction or renovation. Triple glazing offers advantages that every builder should consider when buying, and impresses with the following features:
Triple glazing / Most important in one place
- Excellent insulation values: Ug up to 0.4 W / m2 K
- Reduced heating costs
- High comfort (warm surface without air flow)
- Optimal solar energy input
- High light transmission for natural light in the living room
- Visually there is no difference compared to double glazing
Triple glazing can be installed in all our windows.

SAVE ENERGY AND MONEY WITH TRIPLE GLAZING
Older and simply glazed windows leak energy and thus raise heating costs. Thermal insulation of modern windows is of better quality than a few years ago. For comparison: One simply glazed window from the early 1980s had an average heat transfer coefficient of about 5-6 W / m2 K. Today’s windows are limited to a maximum U only due to the Energy Saving Ordinance (EnEV 2009)w – value 1.3 W / m2K. In the future, even U are mentionedw – values of 0.95 W / m2K. This leads to a fivefold reduction in costs. However, this is the only way to effectively reduce heating costs and energy consumption. Due to its high energy efficiency, the low cost of triple glazing is quickly depreciated

Example of calculation in relation to old windows with insulating glass (U w value 2.8 W / m 2 K), standard window 1.23 mx 1.48 m. Basis for calculating heating costs: oil heating is 0.7 Euro / liter, window area 50 m.
For residents, this results in financial benefits, while modern apartments and houses with triple glazing offer a significantly high level of comfort.

MORE COMFORT WITH TRIPLE GLAZING
We all know this – in the cold seasons there is a cold flow of air near the window. We freeze near the window, so we turn off the heating more than necessary. But our comfort does not only depend on the room temperature on the surfaces of the floor, walls and windows. A larger temperature difference between individual surfaces results in colder surfaces drawing heat from warmer ones. In humans, this leads to a stronger cooling of the skin which significantly affects our perception of temperature. Triple glazing has a significant impact on both air flow and surface temperature.
THERMAL COMFORT THANKS TO TRIPLE GLAZING
Low heat losses that provide high thermal comfort, all due to the high values of triple glazing insulation. In the case of triple-insulated glass, the partitions are filled with non-thermal precious gases. As a result, very little heat penetrates the outer glass layer and is thus transported outside, which is why the temperature inside the window is also high.
According to a study by the Rosenheim Institute of Window Technology (IFT), comparisons between double and triple glazing at an outdoor temperature of minus 10 degrees Celsius and a room temperature of 20 degrees showed a temperature difference of about 9 degrees. Normally insulated glass had an internal surface temperature of 9.5 degrees, and triple insulated glass had an internal surface temperature of 17.7 degrees. Through a small difference in indoor surface temperature to room temperature and other surface temperatures, well-being is significantly increased. There is no air flow, no cold air, and the shivering near the window is over.
Anyone who wants a new building or is planning a renovation should seriously consider triple glazing and get some comparative offers.
