Climate comfort
The ingenious double effect with heat and cold protection from GAYKO. Pleasantly cool in summer and comfortably warm in winter.
Comfortable comfort in every season and the good feeling of doing something for the climate: GAYKO windows offer all this and much more. In the past decade, energy costs have already increased more than fivefold - and there is no end in sight to the price increases. Anyone who consistently relies on holistic, innovative insulation of the building envelope can reduce energy costs by up to 40%.
The GAYKO thermal protection windows create a much better indoor climate. They reliably block out summer heat and winter cold. With comfortable temperatures in the interior, you can work, sleep and live in a relaxed manner... enjoy the soothing light from your beautiful windows from morning to evening. In addition, you save enormous energy costs for air conditioning and heating.

Expert opinion
Energy-related renovation of existing buildings is the central key
Prof. Dr. Gert Hauser, Fraunhofer Institute (2009-2014):

“The existing buildings must be renovated primarily from the point of view of economic efficiency. The correct U-value from a building physics and economic perspective is crucial - not the lowest! That's why it makes no sense to renovate houses built in the 1960s and 1970s using state-of-the-art technology if the cost-effectiveness is neglected. If we want to solve our climate problems, we have to start with the building sector, and windows play a very central role in this area. In addition to their influence on energy consumption, windows have natural additional effects in terms of increasing comfort. We feel significantly more comfortable near windows if we have good windows.”
Why change the window?
What you need to know about new construction and renovation of your property in terms of thermal insulation.
The thermal protection system from GAYKO
The GAYKO thermal protection system offers you a new generation of windows with the latest technology. Whether in a new building or renovation, GAYKO thermal insulation windows create a pleasant indoor climate: they reliably block out cold and heat. With comfortable interior temperatures between a pleasant 22-24 °C, you can work, sleep and live in a relaxed manner.


"Warm edge" stops thermal bridges and moisture
It's not just through the glass that a house loses heat - there are also enormous temperature losses in the edge connection of the panes. The “warm edge” serves to reduce thermal bridges and condensation on the edge of the pane. The temperature distribution is optimized over the entire surface, the room climate is noticeably improved and the risk of mold formation is effectively reduced - your health will thank you.
Thermal separation with GAYKOTGS
Edge seal and window profile form cold bridges, which cause unfavorable thermal gradients. With GAYKOTGS the steel core is thermally divided into two halves, which prevents thermal bridges. In this way, noticeable thermal protection can be achieved right up to a passive house.


Highly efficient: GAYKO-Thermotec 0.5 glazing
Glazing plays an important role in windows with optimal thermal protection. Even in the standard version, GAYKO offers you above-average thermal insulation glazing with a Ug value of 1.1 W/(m²K). With the GAYKO-Thermotec 0.5 glazing you can achieve the very best values: The 3-pane structure with argon gas filling achieves the excellent Ug value of 0.5 W/(m²K) and is therefore even suitable for passive houses.

Only at GAYKO: unique stability for your new thermal protection window, the extremely stable profile screw connection - GAYKOESP
The heavier and more elastic a pane structure is, the higher the thermal protection and the weight. Good to know: The construction of all GAYKO windows is above average and the type of screw connection is patented. GAYKOESPensures maximum stability, tear resistance and optimal statics. This technology guarantees an extremely long service life and precision for thermal insulation windows - despite increased pane weights. The powerful screw connection ensures a solid hold, as the highest weight load occurs in the area of the hinges. This means that windows with GAYKOESP achieve over 900 kg pull-out strength in the scissor bearing.

Energy saving at passive house level
Are you relying on high energy efficiency and want to create generous window areas? The window of the future must have very good thermal insulation and be able to use solar energy gains through appropriate glazing. This use has a positive effect on the energy balance - valuable resources and your wallet are protected.
With our GAYKOLIFE-PASSIV profile construction, we have developed an energy-optimized window element that already meets the values of future legal standards. Experience a generation of windows with outstanding properties that use thermally separated steel and a foam core to ensure energy-optimized insulation values and more comfort in your home. This is thermal protection at the highest level!
GAYKO initiative “Window and facade industry forum to achieve climate goals”:
As early as 2012, the Windows and Facade industry forum initiated by GAYKO set standards in the area of the correct sequence for building renovations, which are still far ahead of political standards today. Since then it has been clear that anyone who is clever invests in new windows. Because these are the most important component for saving energy and are therefore always number 1 in building renovation.
»In order to achieve climate protection goals in the long term and minimize dependence on imports, renovated building materials are needed that use energy as intelligently as possible. The first hurdle is attention to the issue of energy efficiency. (...) The huge energy saving potential in the building sector must be clearly communicated.«
Quote Dr. h.c. Joschka Fischer (retired Federal Foreign Minister)

Build, renovate & modernize smartly with grants from
RVO or loans from the National Heat Fund

Making your home more sustainable may seem like a big challenge, but it can be done step by step.
There are various ways to save energy depending on your situation. For homeowners, for example, there is the Investment Subsidy for Renewable Energy and Energy Savings (ISDE), which allows you to apply for grants for replacing windows or entire frames.
Making your home more sustainable may seem like a big challenge, but it can be done step by step.

Replacing single glazing improves comfort and saves energy. By replacing single glazing with HR++ glass, you can save hundreds of euros annually.
Insulating glass reduces drafts and condensation. The thermostat can be lowered by one degree without losing comfort. Additionally, insulating glass also provides soundproofing.
With accessible financing, the Heat Fund enables you to implement energy-saving measures for your home or apartment complex. A loan can be arranged quickly, with no hidden costs and at an attractive interest rate. This makes sustainable renovations accessible to everyone.
