Rainscreens/ Ventilated Facades
The need to adhere to ecological and improve cost-efciency is becoming an
increasingly important part of the planning and construction of buildings. Energy
savings, energy efciency labor costs and aesthetics are important criteria about which
decisions have to be made. Facade structures must fulll high demands in terms of
long-term requirements such as protection from the elements, thermal insulation,
durability and low maintenance, design elements, re protection, soundproong as well
as ecological requirements. The decision to incorporate a rainscreen/ ventilated facade
in the design of the building makes it possible to take all of these aspects into account
in a more optimal way.
A conservative approach to the use of natural resources and the comfort and well-
being of the building’s occupants as well as the reduction of long-term cost factors
(e.g. building costs, service life, maintenance costs) are further advantages of
rainscreens/ ventilated facades. Moreover, when it comes to appearance and design
considerations, rainscreens/ ventilated facades open up a multitude of possibilities.
Energy generation systems (solar thermal and photovoltaic) can also be incorporated in
the design. In terms of building physics and from a technical as well as cost efciency
point of view, a rainscreen /ventilated facade provides an optimum solution for the outer
skin of a building, not only in new construction but also in renovation projects.
The main advantages of drained and backed ventilated
rainscreen facade
• Greater protection from the elements provided by the cladding
• Higher functionality in terms of building physics – thermal insulation stays dry thanks
to ventilation
• Higher energy efficiency through use of insulating materials suitable for rainscreens
/ ventilated facades plus innovative substructures make it possible to achieve almost
any desired R-value
• Simpler solutions comprising adjustable substructures for use on uneven supporting
surfaces
• A comfortable indoor climate thanks to a vapor diffusion coefficient that decreases
from inside towards the outside
• Cooling effect in summer thanks to the temperature barrier effect of the ventilation
cavity – excess heat is dissipated through this cavity
• Thermal insulation in winter thanks to the increased heat transition resistance of the
ventilation cavity
• Sustainable method of construction thanks to longer life, lower maintenance and
separate layers (easier demolition and recycling)
• More reliable fire protection through the corresponding choice of system
components and building materials classes
• Soundproofing: the high noise absorption characteristics of mineral wool insulation in
conjunction with thick cladding is capable of achieving a higher noise reduction factor
• Lightning protection: metal substructures and cladding can serve as a natural
lightning conductor, or can be connected to separate lightning conductor systems
