LeichtPanel, our flagship product, is available up to 6 meters in length with a tight precision in dimensional tolerance. LeichtPanel is ideal for covering large and flat surface area with productivity of up to 50 m2 per man-day. Because it comes with steel reinforcement to BSEN Standard, each piece of LeichtPanel functions as a self-supporting lintel, providing consultants-and builders with more options and flexibility in wall design. In addition LeichtPanel comes uniquely with Double Tongue & Groove profile, offering double the protection against water ingress when installed as external wall facade.
