Research building
„Sandwich-Demo-House“

The industry association for metal
construction systems (IFBS) has in
cooperation with the Technical University,
faculty of Civil Engineering, RWTH in
Aachen, Germany, fabricated a research
building with the goal to test and optimise
metal building constructions as a whole.

The demo house is constructed using the
sandwich/composite technology to analyse
air tightness and building structure
characteristics. For example, new
constructions should be tested for improved
heat retention and noise reduction.

ISO-Chemie was able to, with the supply
of sealing tapes and profile fillers, make an
important contribution to the development
of the research building and prove the
ability of the system components.

In order to improve the total energy balance
of buildings the requirements for joint
impermeability is continuously being increased.

EnEV-Amendment

In the last energy saving regulations amendment, air-tightness for the
building envelopes was increased. Buildings are to be constructed in such
a way that both the building envelope (heat loss through transmission)
and the joints in the envelope be permanently airtight in accordance with
the state-of-the-art technology. They also must conform to the new
minimum thermal insulation and thermal bridging standards, to reduce the
yearly heating requirements as much as possible.

IFBS-guideline

The German industrial association for metal building constructions
(IFBS) demands a special sealing of building joints between
metal construction elements in order to continue the
sealing over the individual building elements and
construction sections. Stipulated by the EnEV (energy
saving regulations) and other engineering rules,
these guidelines stress that internal partitioning
constructions are airtight as well as temperature
stable and possess the necessary thermal,
acoustic, moisture and fire protection.
