MEP SUBSTRUCTURE SYSTEM
FOR VENTILATED FACADES

01. Substructure for ventilated facades

MEP subconstruction for ventilated facades, made as a cold-formed steel structure in accordance with EN 1090-4 norm, consisting of metal consoles and a metal cross grate. The continuous sections of the substructure are the main framework, attached directly to the consoles, and the secondary framework, to which plate or panel facing elements, including perforated and expanded, can be attached. The components of the substructure are made of galvanized or stainless steel. MEP HXL consoles are protected by patent applications.

The substructure comes in two variants:

  • with the main vertical sections MEP_01
  • with the main horizontal sections MEP_02.

02. VENTILATED FACADE WITH CROSS SUBCONSTRUCTION

The MEP substructure allows the technical part of the ventilated facade (A), related to the load capacity, thermal insulation, etc., to be independent from the aesthetic part (B) related to the division of facing elements on the facade (A ≠ B).

The MEP substructure, characterized by a cross arrangement of main and secondary sections, allows freedom in shaping façade divisions independent of the mesh of the main substructure, resulting primarily from strength requirements.

04. MEP IN PRACTICE

MEP SUBSTRUCTURE MEANS:

  • up to 3x  consoles
  • less heat loss
  • cost saving
  • time saving during the assembly

WITH MORE FLEXIBILITY

*-Uc was calculated taking into account the corrections for point thermal bridges from assembly consoles and pins fixing thermal insulation. 20 cm thick plastered reinforced concrete wall and 180 mm mineral wool (lambda = 0.034 W / sqm*K) were used for calculations

05. COMPONENTS OF MEP SUBCONSTRUCTION
MEP_01

Lower number of consoles than in standard solutions means:

  • less thermal point bridges and, effectively,   lower heat transfer coefficient for the partition
  • fewer anchoring points
  • reduction of assembly time and costs

Consoles come in four types, made of galvanized steel sheet, stainless steel sheet (three times lower thermal conductivity than ordinary steel). Consoles of both materials can have perforated shelves, which also limits the correction to Uc (even better technical parameters of the partition).

An additional advantage of MEP consoles is their versatility. The same console can be used in MEP_01 and MEP_02.

05. COMPONENTS OF MEP SUBCONSTRUCTION
MEP_01

The main grate of the MEP substructure for the facade is characterized by:

  • the possibility of adapting the profile spacing to the dimensions of thermal insulation boards, and thus reducing the consumption of insulation material
  • lower temperature expansion than in case of commonly used aluminum substructures

The substructure of the MEP system for ventilated facades has been tested to meet §225 Technical Conditions according to Polish Building Law::

"§225. Facing elements of facade should be attached to the building structure in a way that prevents them from falling off in the event of a fire in a shorter time than that resulting from the required fire resistance class for the external wall, referred to in § 216 subsection 1, according to the fire resistance class of the building in which they are fixed."

MEP received a positive opinion from ITB and can be successfully used even in high-rise buildings in fire resistance class A.

05. COMPONENTS OF MEP SUBCONSTRUCTION
MEP_01

The MEP system allows to adjust the profile spacing to the dimensions of thermal insulation boards, and thus to reduce waste of material, which is the result of a need to trim those boards.

All types of thermal insulation that are intended for installation in ventilated facades are allowed.

Limit the number and value of thermal bridges by increasing the spacing of assembly consoles and using materials with a low thermal conductivity coefficient for their production. This has a positive effect on reducing heat loss, the external wall with the facade in the MEP system, using appropriate thermal insulation, meets the requirements for the heat transfer coefficient specified in Technical Conditions from 01.01.2021, i.e. Uc <0.2 W / sqm*K.

05. COMPONENTS OF MEP SUBCONSTRUCTION
MEP_01

MEP secondary grate allows:

  • free shaping of facing element division on the facade,
  • moving the consoles away from the edges of window openings - no collision between the sealing of  joinery and the structure of the building
  • easy shaping of the finish
  • freedom in shaping the cross-sections for individual use

The use of a cross-section system of the substructure gives freedom and ease of installation and means universal solution for most facing elements. The MEP subconstruction enables making the "facade drawing" independent from the section structure of the subconstruction, which creates the possibility of making very complicated facades and makes it easier to solve architectural details.

05. COMPONENTS OF MEP SUBCONSTRUCTION
MEP_01

The MEP system allows:

  • the use of various types of façade elements
  • easy shaping of façade divisions
  • stable support of facing elements

Facing elements can be made of: metal, composite materials, HPL high pressure laminates, Rockpanel, fiber cement, fiber reinforced plastics, etc.

07. horisontal or vertical?

The MEP cross subconstruction is available in two variants:

  • with main vertical sections – MEP_01
  • with main horizontal sections – MEP_02

The choice of the optimal type of the subconstruction mainly depends on the layout and type of the facing elements, the arrangement of windows, doors and glass elements on the facade.

When choosing a subconstruction system, follow the guidelines of the lining component manufacturers regarding assembly technology and the simplicity of making the detail and contact with other materials (e.g. glyphs / columns at the holes).
