The ALTI™ composite system seamlessly blends the durability of aluminium with the natural warmth and beauty of timber. On the exterior, aluminium provides strength, weather resistance, and low maintenance. On the interior, timber enhances the space with rich textures, warmth to the touch, and timeless elegance. The best of both worlds.

Built to NZS4211 standards, ALTI™ delivers thermal efficiency, durability, and security, while its customizable styles, timber species, and hardware options ensure it complements both classic villas and modern architectural homes.
