The SW25 sandwich wall is an alternative solution to the standard wall in situations where space and weight play important roles. It also has the B-15 fire classification. The assembly is based on the tongue and groove principle. The wall is connected to the floor using prefabricated U-shaped sections, available in a number of different lengths from the manufacturer. The sections are laid out and fastened onto the floor.

A large variety of surface finishes are available; all of them have a removable protective foil to prevent any damage from occurring during installation. The design of the SW25 wall panel system and all components used have been tested and approved according to international standards.
