Construction

This is the outermost layer, which serves to protect against driving rain, separated by an air layer from the underlying layers. According to DIN 18516-1, the design of the cladding, the ventilation zone, the insulation and the sub-structure is composed. Requirement is a weight-bearing base material.

The system allows the selection of different façade cladding.

The outermost layer ( = cladding ) can be made of wood, natural stone, artificial stone, ceramic, metal sheet ( eg galvanized sheet metal or copper plates) or composite materials ( for example glass fiber reinforced concrete and fiber cement ) made ​​up to opaque glass.

Technical regulations

Ventilated facades are specified in DIN 18516-1 for external walls, ventilated, Part 1: Requirements, testing requirements. Curtain walls and Pfosten-/Riegelkonstruktionen subject to the requirements of the standard series DIN EN 13830 and require a CE mark since 2005.

Pros and Cons

A curtain wall is considerably more expensive than other exterior wall structures such as exterior insulation and finish systems generally. On the other hand, the separation of thermal insulation and weather protection benefits in the design and the design possibilities.

Assembly

Step 2: Attaching the insulation, foil, supporting profiles

Step 3: Attaching the cladding
