ALUPROF MB-79N
MB-79N, the latest proposal from Aluprof, is an economical and modern window and door system. Designed with increased thermal insulation requirements in mind, it allows a variety of constructions to be realised, such as fixed windows, casement windows, tilt and turn windows, tilt and slide windows, single and double-leaf external doors, or display cabinets with doors.
In addition to the MB-79N E economic version with a single-component central gasket in the windows, the MB-79N ST version with a two-component central gasket is also available. The system also offers the MB-79N SI variant, characterised by the highest thermal insulation, with profiles fitted with insulating inserts and a two-component central gasket. For external doors, an additional variant MB-79N SI+ is available with insulating inserts inside the profiles and a central gasket. The range is complemented by the MB-79N Casement outward opening window system with thermal break and the MB-79N US concealed sash window system.
UW from 0,64 W/(m2K)
FUNCTIONALITY AND AESTHETICS
- profiles with a depth of 79 mm (window casement) and 70 mm (frame and door casement)
- thermal breaks made of an innovative material with a new shape, allowing the seal to be applied to the profile insulation zone in both windows and doors
- 3 thermal construction variants for windows (MB-79N E, MB-79N ST, MB-79N SI) and 3 variants for doors (MB-79N ST, MB-79N SI and MB-79N SI+)
- construction that meets the requirements of the Technical Conditions from 2021 for windows (0,9 W/(m2K) and doors (1,3 W/(m2K))
- thermal insulation: UW from 0,64 W/(m2K)
- very good kinematics, allowing for the construction of narrow opening windows
- the door leaf profiles have an expansion joint, which eliminates thermal stress during use
- the possibility of using invisible hinges and the most popular perimeter fittings, including concealed fittings, together with the state-of-the-art AluPilot window fitting; fittings with automation and access control functions are also available on doors
- a wide range of glazing with 2- or triple glazing packets with a thickness of up to 63 mm for windows and up to 54 mm for doors, which allows the use of all common types of glass, including acoustic or burglar-proof glass
- possibility to produce burglar-proof doors in classes RC1 – RC3 as well as panel doors, offering a wide range of aesthetic possibilities
- a large selection of handles in different design ranges, including handles with a visible escutcheon or without escutcheons, with a minimalist look
- an outward opening window variant with thermal break MB-79N Casement and a window variant with concealed casement MB-79N US are available
