About MaxiWall AAC Panel System
MaxiWall is Big River’s autoclaved aerated concrete (AAC) panel system for internal and external walling. The panels offer superior thermal and acoustic performance in a lightweight, easy-to-install format that dramatically reduces construction time compared to brick or block.
MaxiWall panels are pre-finished, eliminating the need for rendering or cladding in many applications. They are fire-resistant, termite-proof, and deliver excellent energy efficiency ratings, making them ideal for residential, commercial, and multi-storey construction.
