Klaus Gayko

I would like to leave you with this.

Window technology has advanced rapidly in recent years: high-tech innovations, stylish design, intelligent functions and sophisticated technology. Just think of the development of insulation values. According to the Fraunhofer Institute for Building Physics, 92.5 percent of all German households have a high potential for improvement in the area of ​​windows and doors. If you take the idea of ​​saving energy seriously, also in terms of energy cost trends, all windows built before 1995* would have to be replaced. GAYKO windows usually pay for themselves in the form of saved energy costs, because windows and doors have the highest energy efficiency of any facade. They shape your house technically and visually and ensure peace, security and warmth in your home. Windows are life!

Yours, Klaus Gayko
