Ventilated Façade or Double skin façade consists of two layers (Insulation & Cladding material) separated by air chamber that works like a chimney to allow air circulation (Ventilation), this will help improving the heat insulation which will improve HVAC System efficiency.


  • Modern Look
  • Wide range of material can be used
  • Heat Insulation
  • Acoustic insulation
  • Can be used in any building type
  • Can be done from non-inflammable
  • Flexible in three directions
  • Easy To Install


Surfaces to which the facade can be anchored may consist of standardized materials (e.g. concrete, brick, steel, timber, etc.) or non-standardized materials. Surface layers such as rendering, coatings or facings do not count as load-bearing materials.

The following are suitable base materials:

  • Concrete in accordance with EN 206
  • Bricks in accordance with EN 771
  • Concrete Block Grade A or B with minimum compressive strength of 5N/mm2
  • Sand-lime block in accordance with EN 771
  • Aerated concrete in accordance with EN 771
  • Steel frame structures in accordance with EN 1090
  • Existing / unclassified masonry (load-bearing capacity must be verified by pull-out tests)

Bracket fasteners are used to anchor the Profile Fastener (6) to load-bearing base materials. The fasteners must comply with national and / or European regulations or approval requirements and must also meet the manufacturer‘s installation specifications. The applicable approval must cover the application for which these items are used, i.e. suitability for the demands of rain screen / ventilated facade installation. Where applicable, corrosion protection measures must also be implemented and the compatibility of materials taken into account.

The load-bearing capacity of the bracket fastener can also be verified by carrying out on-the-spot pull-out tests in accordance with, e.g. ETAG 020 Annex B, ETAG 029 Annex B or an equivalent test method.

Based on base material type mentioned above suitable mechanical anchor can be used accordingly.

A layer of thermal insulation between the supporting surface and the ventilation cavity. Depending on the type of insulating material used, it may also fulfil fire protection and soundproofing requirements. Thermal insulation for rain screen / ventilated facades must consist of an insulating material of a type suitable for the intended purpose (exterior wall insulation behind cladding). The insulation must meet the following requirements:

  • Able to retain its shape
  • Able to retain its dimensions
  • Completely hydrophobized and non-vapour retardant (as necessary)
  • Non-flammable (as necessary)
  • The following types of facade insulation can be used, for example:
    • Mineral wool
    • Foam glass
    • Rigid foam sheet
    • Wood fiber board

Insulation sheets must be tightly butted together. This is particularly important at the corners of the building. The thermal insulation must be snugly fitted around the points where the substructure penetrates the insulating material. Where water spray is to be expected, moisture-resistant insulating material must be used.

As a basic rule, national regulations and installation instructions issued by the manufacturer must be observed.

The insulation sheets must be fitted without gaps and reliably, permanently secured (depending on the type of substructure, anchors, adhesive, clamps, screws or mechanical pressure may be used). The wind loads to be expected, also during construction, must be taken into account. Excessive compression of the insulating material at the fastening points should be avoided

The substructure is the static connecting link between the load-bearing outer wall and the facade cladding. It consists of wall brackets with sliding and fixed points and load-bearing metal profiles made from aluminum alloys as per EN 573, EN 755 and EN 485 (6063 T5).

The fixed point takes the weight of the cladding material and substructure and the proportional wind & other load. The flexible points allow temperature expansion of the profiles and bear the proportional wind loads

Substructure components are as follows:

    • Load-bearing Fixed & Sliding brackets
    • T profile
