extended fire resistance »

The Vulcan range of doorsets is specifically designed to meet the requirement for prolonged fire resistance periods of 90 and 120 minutes, although the same performance levels are also available today within many LS Leaderflush Shapland product ranges.

Performance

Fire Resistance
Vulcan doorsets have been successfully subjected to BS 476 :Part 22:1987 fire testing allowing LS Leaderflush Shapland to certificate 90 and 120 minute assemblies. All fire rated products are manufactured strictly in accordance with the BWF-CERTIFIRE scheme. Please contact our Technical Services Department for further details.

Sound Reduction
The Vulcan doorsets, fitted with appropriate acoustic seals, have been tested to the appropriate British Standard and achieved a good level of sound reduction.

Mechanical Strength
BS DD 171 details a range of mechanical tests designed to evaluate the strength of the door in daily use. The Vulcan doorsets achieved ‘Medium Duty’ rating when subjected to these procedures.

External Applications
Vulcan doorsets are suitable for internal use only and should not be installed in external locations or subjected to prolonged damp conditions.

The table below summarises performance and other characteristics.

Construction

Both the Vulcan 90 and 120 consist of a mineral core supported by non-combustible stiles and rails. MDF to each side forms either the final facing for a paint quality door or the substrate for the final facings of veneer, laminate, PVC or durable vinyl. Doors are lipped on all four edges in hardwood as standard.

Configurations

Both single and double leaf assemblies are available and overpanels can also be incorporated.

Frames

Frames are manufactured from non-combustible material and clad in veneer or PVC as required. The standard frame section is 100mm x 39mm Barum with a 14mm x 44mm hardwood planted stop. Non-standard frame widths can be provided on request. Advice should be sought from our Technical Services Department.

Smoke seals

Where smoke control to BS 476 : Part 31.1 : 1983 is required, combined intumescent smoke seals will be provided.

Vision panels

Vulcan doorsets can incorporate apertures with wired and unwired glass.

Ironmongery

Vulcan doorsets can accommodate standard ironmongery. However, the non-combustible stiles, rails and frames prohibit the morticing of locks and other items on site, and LS Leaderflush Shapland must be issued with details of all recessed ironmongery for factory preparation. Where flushbolts are required, these must be steel and installed in the door edge only.

Installation

Doorsets can be installed using traditional fixing methods, although gaps at the back of the frame must be fully filled with mineral wool and sealed with intumescent mastic.
