Riser Doors

Description

A Riser Doorset is a specialized doorset designed for vertical service risers—the enclosed shafts or cupboards that house building services such as electrical, plumbing, HVAC, and data cabling. These doorsets provide secure, compliant access for maintenance while maintaining fire and acoustic integrity.

Definition

A riser doorset is a complete door assembly (frame, leaf, hardware) installed in riser shafts or service cupboards, often in corridors or plant areas. It is engineered to blend with wall finishes while meeting stringent safety standards.
