The ventilated rainscreen façade (VHF) is a proven façade construction in modern architecture.
a proven façade construction in modern architecture,
which, thanks to the technical separation of weather and thermal protection
advantages in terms of building physics combined with excellent
properties during dismantling and recycling.
A disadvantage in terms of energy saving are the thermal bridges
which are formed by the wall brackets in the insulation level
level. The reduction of heat loss from rear-ventilated
ventilated façades depends in particular on the design
design of the wall brackets, which have already been presented in Part 1 of this
of this article. The numerical simulation of the mechanical
and thermal properties for wall brackets made of
made of hot-dip galvanized steel in this Part 2 of the article
shows that different requirements result from both areas.
result from both areas. With a combined approach, which uses the
the required number of wall brackets, the heat losses via the
the façade for a defined load, it is possible to make
basic statements for the most favorable design can be made.
