For the past 25 years, sandwich panel constructions have
been the most popular way to construct food safe rooms in
Europe, because it offers fast installation, is easy to clean
and provides good insulation value. Nevertheless, sandwich
panels are very weak and quickly damaged. Often, kerbs in
this scheme have been made onsite in the manufacturing
plant during construction, composed of concrete and covered
by the floor finishing. This system has some important
disadvantages with regard to food safety, impact resistance
and maintenance.
