WALSC EXTERNAL WALL SYSTEM 50

Consists of 50mm reinforced Walsc AAC Panels fixed to the structural frame of a building with battens in between to form a cavity system.

The orientation of the installed panels are either vertically aligned or horizontally staggered. Each panel orientation represents a different system which have slightly different component details and are not interchangeable on a single building installation unless completely isolated by control joints.

All panel orientation systems include Walsc AAC Adhesive applied to the panel edges where there are adjoining panels and finished using a Walsc approved coating system.
