The MB-79N is a state-of-the art and economical addition to the Aluprof window & door systems. It has been designed to outperform typical thermal insulation requirements. The MB-79N series can be used to fabricate fixed, side-hung, hopper, tilt-and-turn, and hopper-and-slide windows, as well as single and double exterior doors, and storefront solutions complete with doors. In addition to the economical version MB-79N E, featuring a one-component central seal, and the MB-79N ST version with a two-component central seal, Aluprof also offers the MB-79N SI variant with enhanced thermal insulation, and with profiles that come equipped with insulating inserts and a two-component central seal. For external doors, Aluprof also offers the MB-79N SI+ variant that comes with a central seal and insulating inserts inside the profiles.

System characteristics



- profile depth: 79mm (casement) and 70mm (window frame and door leaf)

- thermal breaks made of an innovative material with a brand-new shape allow the use of a seal in the area of profile insulation, in both windows and doors

- windows in 3 thermal variants (MB-79N E, MB-79N ST, MB-79N SI) and doors in 3 thermal variants (MB-79N ST, MB-79N SI and MB-79N SI+)

- thermal insulation: Uw starting from 0,64 W/(m2K), Uf starting from 0,83 W/(m2K)

- excellent kinematics enabling the fabrication of narrow, operable windows and doors

- door leaf profiles have isolation joint, which eliminates thermal stresses during operation

- possibility of using invisible hinges and the most popular multi-point hardware, including hidden fittings + state-of-the art AluPilot fittings; for doors, fittings with automation and access control functions are also available

- able to receive double or triple glazing, up to 63 mm for windows and 54 mm for doors, thus making it possible to use all common types of glass, including acoustic or burglar-resistant glass

- possibility to produce security doors rated RC1 - RC3, and panel doors in many highly aesthetic versions

- large selection & different styles of handles, including minimalist looking handles with or without rosette
