Overview
Precast Aerated Concrete PAC Panels are lightweight, fire resistant, fast and easy to install. PAC panel is a reinforced (Grade 70 steel) element spanning with full story height. PAC Panel is based on a standard 60 cm wide module. The thickness and panel length (height) vary depending on the design requirements and constraints of the project. PAC Panels can be applied vertically or horizontally according to the application. It is produced with a groove from both sides (thickness sides) where grout is poured in case of load bearing wall system. It also comes plain on edges when it is applied as partition walls, boundary walls, shaft walls, cladding on steel structure or concrete structure. In this case, fixation will be through using thin bed mortar PAC Adhesive and steel angles.
