Rainscreen cladding is the attachment of an outer skin of rear-ventilated cladding to a new or existing building. The system is a form of double-wall construction that uses an outer layer to keep out the rain and an inner layer to provide thermal insulation, prevent excessive air leakage and carry wind loading. The outer layer breathes like a skin while the inner layer reduces energy losses.

The structural frame of the building is kept absolutely dry, as water never reaches it or the thermal insulation. Evaporation and drainage in the cavity removes water that penetrates between panel joints. Water droplets are not driven through the panel joints or openings because the rainscreen principle means that wind pressure acting on the outer face of the panel is equalised in the cavity. Therefore, there is no significant pressure differential to drive the rain through joints

Advantages  of Rainscreen Facades include:
  • Thermal bridging is eliminated because there are no interruptions caused by floor slabs.
  • Temperature fluctuations are minimised due to insulation on the outside.
  • Interstitial condensation is prevented as vapour pressure and wall temperature restricts condensation to the ventilated cavity.
  • Heat from the sun is dissipated so that the temperature is dispersed in the cavity and ventilated through openings.



Trespa Meteon is a flat panel manufactured using timber thermosetting resins, homogenously reinforced with wood fibres and manufactured under high pressure and at high temperatures, using a proprietary technology (EBC). The panels have an integrated decorative surface with life expectancy in excess of 50 years and colour warranty for 10 years, backed up by BBA Certification.

Trespa Meteon is used in façade cladding applications, fascias, soffits, balcony panels and balustrades, urban furniture, sandwich panels and a wide range of other exterior applications. Trespa Meteon is suitable for ventilated façade systems. These “breathing” or envelope systems are designed to maximise insulation values,At warmer temperatures, excessive solar heat can be vented away through the ventilation between the panels and the insulation materials.

Trespa Meteon offers over 50 standard colours and various options on decorative surface finishes to one or both panel sides making it possible to create many imaginative concepts when designing the building facade. The range includes an assortment of themed decorative finishes, such as Meteon Naturals designed to compliment the colours of classic building materials, Meteon Metallics which offer a metallic gloss effects, Meteon Wood decors in warm wood shades and Meteon Originals which have unique designs.

Trespa Meteon is available in the standard (non-FR) version (complies with Euro classification B-s2, d0). Both versions have a black core.

Trespa Meteon is available in the following sizes:

  • 3650 x 1860 mm
  • 3050 x 1530 mm
  • 2550 x 1860 mm


Ventilated Facade Cladding Solutions

The composite structure of ALUCOBOND – two Aluminium cover sheets and a plastic or mineral filled core – results in an impressive strength-to-weight ratio, even when comparing large panel sizes.
Despite it’s low weight which makes ALUCOBOND easy to transport and handle in the factory or on site, its rigidity and high strength make it the most suitable material for exterior wall cladding. When properly designed and installed ALUCOBOND panels will keep their shape and remain flat for life, even when exposed to extreme temperature changes.
ALUCOBOND sheets are renowned for the performance of the surface coating. This is achieved by using computer controlled automatic coil coating process. There are a number of fixing methods for ALUCOBOND from mechanical secret fixed systems to rivet or screw fixed.
