MB-86EI

MB-86EI

The system of windows, doors and fireproof walls with thermal insulation MB-86EI helps to execute external fireproof walls, equipped with open windows, doors and fixed walls of the main fire resistance classes EI30, EW30, EI15 according to the PN-EN 13501-2 standard .
Advantages of the MB-86EI system:
  • Profiles with a 3-chamber construction, where the central part is represented by an isolation chamber between the thermal inserts with a width of 43 or 42 mm,
  • The fire insulation elements in the rooms of the interior aluminum profiles and special accessories and functional materials in the space between the aluminum profiles and the glass,
  • In the doors of EI's classroom2 it is not necessary to use fire insulation elements in the inner chambers of aluminum profiles, which influences a faster prefabrication and a lower price of the structure. In the construction of the showcase, inserts are needed in the profiles of the frames and crossbars.
  • The wide range of glass thicknesses that can be used allows the use of various types of insulating glass (insulating glass), including 2-chamber sets,
  • The accessories used in the MB-86EI windows are included as standard in the anti-burglary class RC2.

 

TECHNICAL PARAMETERS OF THE SYSTEM:
  • Air permeability: windows: class 4, doors: class 4, EN 12207
  • Water tightness: windows class E 1500, doors: class E1350 Pa EN 12208
  • Wind resistance: windows: class C5, doors: class C1/B1, EN 12210
  • Thermal insulation: windows: Uf from 1.07 W/(m2K), Uw from 0.86 W/(m2k)*
  • Fire resistance: class EI30, EW30, EI15

The system of windows, doors and fireproof walls with thermal insulation MB-86EI helps to execute external fireproof walls, equipped with open windows, doors and fixed walls of the main fire resistance classes EI30, EW30, EI15 according to the PN-EN 13501-2 standard . The structure is based on the MB-86 system, which is characterized by a high level of thermal and sound insulation and water and air tightness. The MB-86EI system therefore combines the advantages of the classic window and door system with the properties of fire-resistant partitions in the sphere of thermal, utility, resistance parameters and production technology. Its construction meets all the requirements of the provisions and norms in force, especially in terms of energy efficiency and environmental protection, while ensuring adequate fire safety. The system is classified as non-flame spread.
