RISER DOORS SUMMARY
The PROFAB 4000 series range of metal riser doors is available in a variety of designs that can provide up to 4 hours fire resistance into jointless plaster/plasterboard and masonry walls and partitions. Used widely in service shafts, corridors and protected zones where access to mechanical and electrical services is required without compromising aesthetics and fire safety. Access is often a multi-door requirement and can be up to 2800mm in height. The product is available with a variety of lock options, finishes and door configurations including single, double and multi door options. One hour Fire rated (1FR) and two hour fire rated (2FR) designs are also available acoustically shielded to provide up to 35dB RW rating.
COMPOSITION & MANUFACTURE
A precision welded, strong metal frame holds a flush metal door through a concealed pivot hinge (or a series of fully adjustable concealed hinges for the 170 degree opening product). Actual construction varies dependant upon size and fire performance requirements. The door is held closed with a choice of locking systems and opens outwards towards the user. Doors are removable if damage occurs or during installation. Panels with simulated drywall beaded frames (BF) or deep plaster (DPF) are jointed/plastered over on site and finished to match the colour/texture of the adjacent surface. Retrofitted panels have a picture frame surround (PF) and are factory finished in powder coat semigloss white paint. A constant 3mm gap is maintained between the door and frame by the dome location system.
“I requested a sample access panel for a current project and this was delivered to my office within 24 hours. Cannot fault the service.”
“Always quick to respond to enquiries, have used a few times now on different projects, will definitely use again.
Very easy to use and install products..”
Frame: 1.6mm thick electro-galvanised mild steel, incorporating either a simulated dry wall edge bead profile (BF), picture frame (PF) or deep plaster frame (DPF). Factory welded box section to size, fitted with dust and intumescent seals and white powder coated primer or semi-gloss white. Door: 0.9mm thick, electro-galvanised mild steel flush faced tray lined with mineral wool and glass reinforced gypsum board with a white powder coated finish. Locks: Three-point lock (3PL) on the rear of the door but operated from the front face with an included 8mm square drive key. A white round removable cap on the door face conceals the key hole. Locks can be upgraded to include preparation for an additional Europrofile high security cylinder (3HS) if y dimension is 450mm or greater.

All panels above are single door. For larger panels use 4000/2FR/3PL. For multi-door configurations use the 4000/2FR panel. If in doubt contact Profab Technical Services.
KEY INSTALLATION/POINTS TO NOTE
1. X and Y dimensions are outside rear frame.
2. Overall frame depth is 59mm (Dim at fixing angles. Panel sandwich is 34mm.
3. Structural opening required for installation is (X+5) x (Y+5)mm.
The 4000/2FR series
panel has been designed so as not to impair the fire resistant performance of a fire rated wall if installed in it. It will match the tested or assessed construction. All 4000/2FR structural components and fixing methods are non-combustible. Small plastic components will melt, but are not structural.
Fire Test Data
A 2 hour resistance test to BS EN 1634-1:2008 was carried out on a 2000x2400mm 2FR access panel that maintained the integrity criteria for 120 minutes.
Testing and assessments are ongoing. Please contact Profab Technical Services for the latest verification data.
APPLICATIONS & USES
All standard panels are for internal use and only in areas of normal humidity. 4000/2FR/BF or DPF is suitable for vertical use where the panel is being installed prior to any tape and jointing/skim-coat or plastering. 4000/2FR/PF is suitable for vertical use where the panel is being installed after finishing work has completed. The panel is factory finished semi-gloss white so needs no further decoration.
