USING HALSPAN TO CONSTRUCT FIRE DOORS
FABRICATION
|
The structure of the high performance door core in a Halspan door blank removes the need for perimeter framing and ply or MDF faces, simplifying door leaf construction. Halspan is a major advance in the construction of solid core timber fire doors.
Halspan is pre-tested to British Standard BS476: Part 22: 1987 and EN 1634 pt 1 2000, in single leaf doors, pairs and double acting fire door configurations, plus overpanels and glazing. Compliance with test results is essential to retain the integrity of fire doors.
Full specifications will be found in Halspan FD30, FD60 and FD90 Technical Support manuals. Halspan users will obtain these from their supplier of door blanks.

SPECIFYING
|
Halspan Manuals
Information is drawn from Test Reports and Assessments on fire doors constructed from Halspan door blanks, confirming 30, 60 and 90 minutes fire resistance (FD30 & FD60 doors).
The manuals cover leaf and overpanel sizes. Plus specifications for frames, intumescents, lipping, smoke & acoustic control, ironmongery and glazing. Also easy to follow charts and diagrams.

GLAZING
|
The Halspan Glazing Advantage
In some doors, the type of board or construction method precludes glazing. Halspan solves that problem, because it is straightforward to install glazing in all Halspan doors.
Glass Shapes
Halspan allows glazed apertures to be incorporated in fire doors without reducing performance. Square, rectangular, triangular or circular shapes are acceptable provided that the bead, intumescent and fixing details are possible.
Apertures
Halspan solid core door is capable of tolerating relatively large glazed apertures. With Halspan, the aperture is cut directly into the door core/slab. Beads are fitted directly to the particle board.
Glasses & Glazing Systems
Halspan has been tested and assessed for installation with a range of glasses, beads, seals and glazing systems. Alternative systems and glasses may be substituted, provided they demonstrate adequate performance, in the required pane size when tested in timber doorsets of comparable construction.

FACINGS
|
Facings
Halspan is particularly suitable for laminating and veneering. Whether fire door or not, Halspan is successful with veneer and clear lacquer, paint, plastic laminate and metal sheet. Its fine, hard surface minimises preparation time and grin-through and ripple effect, found with other types of door construction, are eliminated.
A reference facility for species and colour finishes is available from Halspan. Contact Halspan Support for information.

PAINTING
|
Painting
It is not essential to add paper or veneer before painting. For best results apply a solvent based primer (to comply with The Environmental Protection Act 1990). Both primer and finish may be applied by spray, roller or brush direct onto Halspan.

INSTALLATION
|
Fixing & Sealing to Structural Openings
Guidance on fixing doorsets, and methods of providing an adequate fire resistant seal to the structural opening, is documented in BS8214: 1990: Table 3, Code of practice for "Fire door assemblies with non-metallic leaves".
