Sandwich wall
Sandwich walls are a special product from the precast concrete component family of facade elements. They are characterised by an insulation layer between both sides of the concrete.
On one side, there is the load-bearing sub-structure of the sandwich wall with the required structural reinforcing, and on the other side, there is the concrete shell that provides the appearance of the sandwich wall and hence also of the building. This visible shell is frequently made of coloured concrete or has various kinds of surface structures.
