Description

The Stryum Aluminium Panel Cladding System is a profiled solid aluminium interlocking linear cladding system used as external wall cladding for all building types, subject to the Conditions and Limitations of Use detailed within this certificate.

The Stryum Aluminium Panel Cladding System consists of solid aluminium cladding panels with either anodised or powder coated surface finish consisting of interlocking profiles:

• Shadow 160, 200 & 300 (Single groove)
• Shadow 90/90 & 170/95 (Double groove)
• Seam 260 (Single ridge)
• Seam 130/130 (Double ridge)

Stryum Aluminium Cladding Panels are secured to timber, steel or masonry structures with concealed fixings, accessories supplied include S section battens, universal trims, shadow trims and seam trims. The Stryum Aluminium Panel Cladding System may be installed over flexible or rigid wall underlay.
