Riser Doors

A riser door provides access to a services riser a vertical shaft running through a building that carries pipework, cabling and ductwork between floors. It allows engineers to inspect and maintain these services while helping maintain the fire compartmentation of the riser shaft when closed.

This range includes riser doors rated at 90 minutes and 2 hours, tested to maintain fire resistance for that period. The correct rating depends on the fire strategy for the building and the specification for that particular riser shaft, so always check the required rating before ordering.

A smoke tested riser door is tested to restrict smoke passage in addition to its fire rating, while an acoustic tested riser door carries a sound reduction rating shown in decibels (dB), such as 33dB or 36dB. Some riser doors in this range combine fire, smoke and acoustic testing for higher-specification locations.

A single riser door has one door leaf and suits smaller riser openings, while a double riser door has two leaves side by side for wider service risers needing a larger clear opening. Both are available with the same fire, smoke and acoustic testing options across this range.

A beaded frame riser door is designed to be plastered into the surrounding wall so the frame is hidden beneath the finished skim coat, giving a flush appearance once decorated. A standard frame riser door instead sits visibly on the wall surface.

Yes, riser doors in this range are fitted with locking systems such as 3-point locking, giving secure closure for shafts containing building services. This restricts access to authorised personnel while keeping the door quick to open for planned maintenance.

Start with the required fire rating 90 minutes or 2 hours then check whether smoke or acoustic testing is specified for that riser location. From there, choose single or double doors based on the shaft width and a standard or beaded frame depending on the finish needed.

Riser doors and access panels serve a similar purpose concealed access to building services but riser doors are generally larger, heavier-duty units designed specifically for vertical service risers in commercial buildings. Access panels tend to cover smaller, more general access points in walls and ceilings.
