WEST BAR BUILDING 4, SHEFFIELD

Ash & Lacy anodised aluminium rainscreen cladding, SFS with CP Board and external membranes, Tenmat firestopping, plant room perforated cladding panels, ground floor aluminium soffit cladding and GRC column casings.

The package required precise fabrication across several distinct system types, each with its own tolerances and interface requirements.

The primary cladding element – Ash & Lacy anodised aluminium panels – demanded consistent finish at scale. Maintaining uniformity across an anodised aluminium finish is a known technical challenge: achieving consistency across 1,500m² required careful management of panel production and sequencing.

The GRC column casings at colonnade level presented a second technically demanding scope item. The columns – large-diameter circular casings forming the covered walkway beneath the building’s overhang – required precise moulding, dimensional accuracy and a consistent surface finish. The interface between each GRC column, the aluminium soffit above and the glazed ground floor envelope required careful co-ordination throughout the installation.

Plant room perforated cladding panels and aluminium soffit cladding completed HKL’s scope, with Tenmat firestopping detailing applied throughout.
