Wussten Sie schon: Dass alle vor 1995 produzierten Fenster technisch völlig veraltet sind?

Save energy systematically

Windows installed before 1995 burn up your money!*


To save, you must do something, preferably immediately. It doesn't pay to wait because the conditions around modernizing for energy saving are so good today that every house owner who doesn't act now will be spending his hard-earned money on much too high heating costs for far too long.

With the oil price rising at 5% per year, a study from dena (German Energy Agency) calculates dramatic losses of money for those who don't renovate their houses. Whereas in the next 10 years a non-renovated house would gobble up 41,000 euros for heating and hot water, a house modernised to the low-energy house standard 55 would need only 8,000 euros. This would enable the cost of energy to be reduced by 33,000 euros over 10 years. So it is worth while to install energy-saving windows in a renovation.

* The calculations in the Heat Insulation Ordinance included window insulation values for the first time in 1994. As regards energy and technology, windows made before 1995 are therefore long out of date and replacing them should be regarded as imperative.

The pay-off for energy-saving renovation is obvious.


Thermal insulation technology from GAYKO

Logo TGS 200

The thermal insulation system from GAYKO offers you a new generation of windows with the latest technology. High-tech thermal insulation glass, "warm edge" and thermal break (GAYKOTGS) in the frame and the casements make your home more cosy and comfortable. In the winter they maintain the surface temperature of the frame and the inner pane close to the room temperature. The patented GAYKOESP gives the ideal design for heavier panes and provides strength and long life for your windows.

High efficiency:

High-tech insulating glass units


In windows intended to provide optimal thermal insulation, the glazing plays an important role. GAYKO already offers you very good high-tech insulated glazing with a Ug value of 1.1 W/(m²K) in the standard version. With Gayko Super insulating glass units you get the best values of all: The triple pane argon gas-filled construction achieves the outstanding Ug value of 0.5 W/(m2K), which makes it suitable even for passive houses.

Stop cold bridges

"warm edge"

Warme Kante

It's not only through the glass that a house loses heat - there are also huge losses in the bonding at the edges of the panes. The "warm edge" helps to reduce cold bridges and condensed water at the edge of the pane. Temperature distribution is optimized over the whole surface, the atmosphere in the room is noticeably improved and build-up of mould is effectively reduced.

Thermal breaks



For further improving the thermal insulation properties of a window, a thermal break between the frame and the casement is useful. In the GAYKOTGS, the entire window is separated thermally into two halves and all cold bridges are removed. This helps to achieve such a high energy efficiency that GAYKO windows are also suitable for passive houses.

Did you know: that all windows manufactured before 1995 are ENERGY GOBBLERS?
