ALUCOBOND® PLUS
Developed to comply with more stringent fire safety requirements in architecture
ALUCOBOND® PLUS is a composite panel consisting of two aluminium cover sheets with a mineral-filled polymer core. It was specially developed for more stringent fire safety requirements in architecture. Thanks to the flame-retardant mineral core, ALUCOBOND® PLUS achieves better fire ratings than aluminium composite panels with a black PE core. The façade panel offers the proven product properties of the ALUCOBOND® family, such as flatness, formability, weather resistance and ease of processing.

Wind loads and panel dimensions
In Germany, the dimensioning of ALUCOBOND® façade systems is regulated by the general building approval (abZ) No. Z-10.3-774. In the Technical Extras section, you can find this and other documents, including load tables, dimensioning aids and various design examples at Technical extras.
