A riser door is a full height or oversized access door fitted into walls to allow maintenance access to vertical service risers in multi storey buildings. These risers carry essential building infrastructure, plumbing, electrical cabling, gas pipework, HVAC ducting, and fire suppression systems, between floors. Where risers pass through fire compartment walls, the door must maintain the same level of fire resistance, acoustic performance, and airtightness as the surrounding structure.
At Rapid Access, our riser doors are available in metal faced and plasterboard faced options, with fire ratings up to 4 hours / 240 minutes (BS476, valid to 2029) on R51 premium, acoustic performance up to 40dB Rw, and smoke sealed variants available. R13 budget riser doors are documented in PIM as tested to BS EN 1634-1: 2014+A1:2018; R57 acoustic doors to BS EN ISO 10140-2: 2010. Specific test certificates available on request.
Every riser door is manufactured from Zintec steel at our UK factory and available in single door, double door and multi door configurations from 300×300mm up to 2400×1000mm per leaf, with double doors available up to 2400×1800mm overall. Where the riser does not pass through a fire compartment wall and no fire rating is required, our non-fire-rated riser doors are a lower-cost option.
