• The facade joinery is implemented with high-quality products of reputable and proven manufacturers from Germany and Greece. The excellent thermal insulation characteristics are determined by the following elements – profile and glazing. The selected profile of joinery is 5-chamber, PVC, Class A, manufactured in Germany, with excellent thermal insulation properties. The profile is being protected from weather and solar radiation by outdoor mounting of additional aluminum cap. The glazing has a minimum thickness of 40 mm, filled with argon gas. Special coatings and glass (low-emission and energy) are also applied, which contributes to further increase of the energy efficiency of the building. The complex heat transfer coefficient of the joinery is very low and is comparable to that of passive buildings.
