ALUPROF MB-79N US — aluminium Windows system

ALUPROF MB-79N US

Aluminium window with hidden transom

ALUPROF MB-79N US is an economical and functional aluminium window system where transoms are invisible from the outside — adjacent fixed and openable windows cannot be distinguished, creating a uniform facade appearance. The system is available in two mullion variants: Type-A frame partially covers the transom, while Type-B frame completely covers it, ideally imitating a fixed window. Three thermal insulation versions are offered — MB-79N US E (economical), MB-79N US ST (with two-component seal) and MB-79N US SI (best thermal insulation with insulating inserts and two-component seal). The system provides excellent thermal insulation, sound insulation, as well as water and air tightness. The maximum transom size is 2.7 m in height and 1.7 m in width with a maximum weight of up to 160 kg, and it is compatible with other ALUPROF MB-79N family solutions.
