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.

With a mass of only 20.6 kg/m², the aluminum version is especially used when the weight on board plays an important role. If the 50 mm air gap between the walls is filled with low density insulation, the sound reduction can be increased up to 42 dB.

This wall panel system is a sandwich construction that combines a B-15 fire classification with a low weight. By using the tongue and groove principle with an integrated tongue on one panel side, the SW25NF wall panel reaches a mass of only 15.6kg/mÂ

The SW25NFP double sandwich wall has been developed to meet very stringent noise-insulation requirements when two adjacent compartments need to be separated.

The 25 mm-thick corner panels can be fitted into the wall panels SW25 and SW25NF to form a flush connection. This ensures an excellent finish, especially in areas with high aesthetic requirements, as there is no joint where the two panels meet.
