BUILDING PERFORMANCE

Insulation
MAGE FaçadeTEC Systems allows the depth of the
substructure to vary from 25mm to >370mm. There is,
therefore, the option of placing insulation within the cavity
outside the structure thereby reducing thermal shorts and
optimizing the mass performance of the structure.

Sound insulation
The presence of an air gap and insulation results in sound
reduction index performance improvement of up to 14 dB.

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-inflammable« 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.
