GLASS DOOR > Aluminium MB79N SI

Single or double leaf doors made in this system meet increased thermal and acoustic requirements, which can be attributed to its structure with applied sealing including a threshold with a thermal break.


  1. Doors in MB-79N SI system constitute the perfect solution that combines durability, aesthetics and modern design.

  2. Huge choice in the RAL color range allows to match any architectural style.

  3. High-quality aluminum profiles resist adverse effects of weather conditions.

  4. Door made in this system stand out for elegance and modern design, and at the same time they guarantee high parameters in energy efficiency  thanks to the innovative EPDM seal system. 

Technical Data

Profile System

The structural depth of the leaf sections and the frame is the same and amounts 70 mm. The structure provides for alignment with both of the sections either from the outside or from the inside. The leaf profiles dilate so that thermal strains, which occur during use, are eliminated.

Colour range

According to the RAL color range and wood-grain coating from Aluprof ColorCollection


3-point automatic espagnolette MACO; 3-winged, roller hinges or hidden hinges.

Spacer frame

Swisspacer Ultimate warm spacing edge in 3 colour variants.


Glass and cover gaskets made of 3 EPDM in standard.

Thermal Transmittance

Ud = 1,0 W/(m2K)*

*Single-leaf door measuring 1,100x2,300 mm, with glass packet T4/U18/FL4/U18/T4  + Swisspacer spacing edge – calculation method.

Painting technology of Drutex aluminium woodwork is among the top technologies available on the global market. It ensures corrosion protection even in the most aggressive sea and industrial environment. The anodal layer ensures perfect powder paint adhesion and it fully protects the structure against filiform corrosion.

Powder Coating

The powder paint that Drutex applies is from renowned producers with years of experience on the architecture market. Their coating stands out for perfect resistance to weather conditions, are easy to maintain and they ensure superb appearance for years.

Our collection includes timeless matt finishes, elegant structures, sophisticated metallic paint as well as special effects such as anodal paint and wood effect.



Coating Quality and Resistance

Powder varnishing ensures a more uniform coating and higher resistance to abrasion, mechanical damage and UV radiation than the so called wet coating, which allows to maintain aesthetic qualities and colour durability for years


The powder coating technology, thanks to the possibility to retrieve unused paint, is the most beneficial for environmental protection. Combined with the cutting edge technology and no need to use solvents, it ensures maximum safety also when it comes to ecology.


Wide Colour Range and Optional Coating Structures

The offer includes dozens of colours as well as structural coating, which enables a perfect arrangement of the building and product functionality (by giving smoothness or roughness)


Environmental Protection

While designing the paint shop environmental aspects were key importance to Drutex. Apart from prolonging lifespan of their products, they minimize impact on the environment through:

  • innovative systems or rotary doors in the oven that minimizes heat loss

  • low temperature degreasing and digestion

  • their own waste water treatment plant complying with stringent EU requirements

  • cutting edge system of paint feeding ensuring almost 100% product use

  • close water circulation with the capacity of 12000 litres per hour

  • not using products containing Cr (VI)
