ALUMINIUM WINDOWS AND DOORS
MB-79N is the most modern economic window and door system in the Aluprof offer. It was introduced with the thought of meeting higher thermal insulation requirements.
It is used to make structures which include: fixed, tilt, turn, tilt & turn, tilt & slide windows, as well as single and double-leaf external doors and window display solutions with doors.
- profiles with a depth of 79 mm (window casement) and 70 mm (frame and door leaf)
- 3 thermal construction variants: MB-79N E, MB-79N ST, MB-79N SI
- thermal breaks made of a new, innovative material which allows the use of a seal in the profile insulation zone in both windows and doors
- thermal insulation: Uw from 0,64 W/(m2K), Uf from 0,83 W/(m2K)
- very good kinematics, which allows for building narrow opening windows and doors
- door leaf profiles are provided with an expansion joint, which eliminates thermal stresses during their operation
