Sandwich panels are prefabricated façade elements consisting of several layers. The structural base course is combined with the thermal insulation layer and the facing shell to form a single component.
Advantages:
- good quality monitoring due to production in the factory
- integrated thermal insulation
fire - resistance class F90
- good sound insulation
- high impact resistance
- individual surface design possible
production according to negative production
- facing shell lies on the switching table at the bottom
- separating layer is applied
- to itSandwich panel anchors are installed
- Thermal insulation layer is installed
- Base course with reinforcement is concreted
Production after positive production
- Negative process as a basis (order changed)
- Facing shell is at the end of the manufacturing process
- Disadvantage: Appearance of the facing shells may not be uniform
Production with lost formwork
- Lost formwork concreted in the factory
- Base course is then produced as in-situ concrete
