System Overview

Zero Combustible Element

The Solid Panel A1 is precision-machined from a single skin of high-grade aluminium alloy, with no core material and no composite lamination. Its surface carries a PVDF fluorocarbon coating, available in a broad range of colours and finishes — solid, metallic, anodised, wood, stone and corten. The panel can be perforated, curved and folded, offering full freedom of form.

Because it contains no core and no combustible element, A1 is an inherent material property rather than the result of any treatment or additive — and it is the maximum classification achievable under EN 13501-1, increasingly mandated by high-rise facade regulations across Europe, the UK and the GCC.
