Located directly on the River Elbe and surrounded by the orchards of the Altes Land region, a modern holiday residence has been built in Grünendeich near Hamburg. Since opening to its first guests in summer 2025, it has received consistently positive feedback. A key contribution to the high level of comfort comes from the SANCO Sun COMBI insulating glass units, manufactured by SANCO partner Stader Glas. SANCO solar control glass with its specialised coatings combines effective heat protection with high light transmittance. In the temperate Central European climate of the Altes Land, selecting the right coating requires a balanced ratio of solar control, light transmittance, and thermal insulation.

Solar control, thermal insulation, and light transmittance combined
The SANCO Sun COMBI insulating glass was selected for Grünendeich because it unites all three of these advantages. Specifically, the Ug-value is 1.0 W/(m²K), the g-value is 37 percent, and the light transmittance is 70 percent. This ensures the holiday apartments maintain a comfortable indoor temperature throughout the year – without sacrificing natural daylight.

The new holiday residence on the banks of the Elbe in Grünendeich is a prime example of how well-considered glazing solutions can enhance comfort while meeting the energy-efficiency requirements of modern buildings.
