Even standard design Koemmerling Eurofutur 70 systems have excelent insulation and sound protection properties. These values can be improved even more with special thermal or noise protection glazing. In addition to the basis safety features of this window system, a top level of security can be achived with the regards to beak-in prevention with security hardware, reinforced glass and locking handles.
Maximum acoustic values, due to the 70 mm installation depth and the possibility of having maximal glass surfaces when the slim, slender profiles are used.
Integrating innovative design protected steel reinforcement into a six chamber design with excellent static and great durability.
All the PVC profiles are stabilised with environmentally-friendly Greenline calcium-zinc instead of lead.
