Technical advantages

Protection against moisture and condensation

Due to the structure of the back ventilated rainsreen facade , the vapour diffusion resistance decreases from the inside to the outside. Any moisture from condensation or accumulated during construction is channelled away through the ventilated space.

Rain protection

The facade is the structural component which is most likely to be damaged. Due to the constant influence of the weather, moisture damage and
cracks will emerge over the years.
With single skin construction this becomes a major issue for the integrity of the building – a problem
well known in some Western countries. Back ventilated rainsreen facade , belong to the
load group III according to DIN 4108-3 and is water resistant. The ventilation space between the insulation and lining (weather-resistance barrier) quickly voids dampness. Hung, ventilated facades can, therefore, be constructed with open, horizontal seams without decreasing the protection against rain.

Lightning protection

By applying an aluminium rainscreen support systems, conventional lightning rods can be omitted and an electromagnetic shielding of the building can be achieved.

Fire protection

Due to the wide choice regarding the system components of back ventilated rainscreen facade, the fire protection requirements »non-infl ammable« or »hardly inflammable« can be met according to country specific building legislation.

Allowance for movement

Thermal gradients, differential thermal movement of components and differential movement through changes in humidity challenge the integrity of any building envelope. Aluminium rainscreen cladding support systems allow for this movement through the use of fixed and sliding attachments for each profile.
