Support construction
The supporting construction may be


 * Timber stud and frame (FZD5114)
 * Steel stud with head and base track (FZD5115)
 * Plasterboard partition with plasterboard on both faces of the stud
 * Masonry wall
 * FORZA timber framed glazed partition (FZD5116)

Integrity

 * All types must provide over 30 minutes of fire resistance at the required size with FD30 timber door assembly openings.
 * If fitted into a proprietary demountable and relocatable partition system providing in excess of 30 minutes fire resistance the method of forming the timber door assembly aperture must be as tested by the partition manufacturer.
 * Limitation of allowable elevations/leaf sizes and ironmongery as tested and specified by the partition manufacturer shall take total precedence over Forza data.

Threshold

 * A raised access floor can replace a masonry floor in supporting construction if it maintains the fire resistance line beneath the raised floor in the same plane as the door assembly.
 * The total floor construction must have the same fire resistance duration as required for the assembly.
 * The raised floor construction should allow robust fixing and adequate support for the required fire resistance duration.

Threshold
The threshold (FZD5132) under the door leaf must be formed of non-combustible materials that form part of the floor system including boards, masonry or ceramics but exclude metals. Alternatively timber or Aluminium thresholds may be installed that form part of the floor system.

Timber Threshold

 * Timber thresholds should be flush to the Finished Floor Level (FFL), with a minimum thickness of 15mm. The width should be 62mm for a 44mm leaf and 72mm for a 54mm leaf, using hardwood with a minimum density of 640 kg/m³.
 * The bottom of the door leaf should have an additional 20mm x 4mm intumescent strip (same type as vertical edges) or an automatic drop seal. The seal should be lined with 2mm graphite intumescent on both sides.

Aluminum Threshold

 * Aluminum thresholds should have a maximum height of 6mm above the FFL. They should be bedded on 2mm graphite intumescent material for their entire footprint and installed to finish against the frame, with the stop cut to fit over the threshold.

See Note; Gap Tolerance Leaf to Threshold.

Timber door frame
The overall frame depth may be increased either in solid form or with the use of extension linings where the joint/biscuit between the extension and the main frame, which must retain its minimum frame depth, does not intrude into the plane of the door thickness. Back to Back frames are permitted as per drawing FZD0606 @ Forza-doors.com.

Transom Specifications

 * For a transom between an overpanel and single-acting door assembly, it should be equal to the frame depth and 32mm thick, plus a minimum 12mm thick stop on both the leaf and transom side. This results in a minimum 56mm thick section.
 * For a double-acting assembly, the transom should be equal to the frame depth and 44mm thick.

Joint Fixing

 * The joint fixing to the frame can be either butt joint, mortice & tenon, or half-lapped.
 * The joint should be glued and twice screwed.

Metal door frames
Forza FD30 leaves may be installed into Aluminium and Steel frames to the frame specification and minimum dimensions detailed in Table 3.

Aluminum frames

 * Aluminium frames (elevations A, B & C only) shall wrap around the edge of the steel stud plasterboard partition, such that it intimately fits against the plasterboard (FZD0103) or may be installed over a hardwood (min. density 640kg/m3) lining to a structural opening.
 * Fixing to the supporting construction to be as tested by the Aluminium frame supplier.

Steel frames

 * The method of forming the door assembly aperture and fixings for steel frames must be as tested by the frame supplier/manufacturer.

Smoke control gaps

 * The gap for smoke control between the door and metal frame, double door meeting stiles and under the door to finished floor level shall be as tested by the frame or partition supplier/manufacturer. There shall be no feature rebates or shadow gaps at the junction of the frame and wall with steel or aluminium frames.

Frame and Wall Junctions

 * There should be no feature rebates or shadow gaps where the frame meets the wall with steel or aluminum frames.

Frame Fixing

 * Frames must be fixed to the supporting construction with steel fixings.
 * Fixings should be placed at centers not exceeding 600mm on the vertical edges, with a minimum of 200mm from the top and bottom.
 * For double doors, a minimum of one fixing should be fitted centrally across the width of the frame head.
 * Screws must penetrate the supporting construction by at least 40mm and be positioned centrally across the frame depth.
 * A twin line of screws might be required for increased frame depths or based on supporting construction type.
 * Use appropriately thick packers at all fixing positions, depending on the gap between the frame and the supporting construction.

Gap Between Frame and Supporting Construction

 * When architraves are used, the gap should be between 5mm and a maximum of 10mm.
 * This allows for intumescent mastic (approved linear gap intumescent mastic tested per BS476-20 or BS EN 1366-4) and mineral wool to be positioned as shown in drawing DRW1.

Riser door(s)
Door leaves may be installed in a four Sided frame (Elevation ‘P’ Single and Elevation ‘Q’ Double) with the base of the frame at a higher level than the finished floor level: maximum permitted height of upstand from FFL to Sill 900mm (such height to be inclusive of the leaf maximum permitted height). Requires additional 20 x 4mm intumescent seal in the base of the leaf(s).

Smoke control
Forza FD30s fire door labels are affixed to the top of the door leaf when the Forza tested smoke control gasket (ST1009) is installed on the full perimeter door stop of the single /double door assembly (meeting style and overpanel edge to include single fin combined gasket).

Various manufacturers smoke seals or combined intumescent smoke seals that have been tested in accordance with BS EN 1634-3:2004 (ambient temperature) or BS476: part 31: section 31, 1:1983 and demonstrated not to leak by more than 3m3/m/hr (head and jambs only) at 25Pa, may also be used in conjunction with Forza door assemblies to provide smoke control (Forza unable to affix an “S” label in these instances).

To achieve the required smoke control:


 * The seal orientation, hardware interruption, door edge gaps, and leaf configuration must match the tested specifications from the seal manufacturer.
 * The threshold gap should be sealed with a flexible edge or automatic drop seal that matches the leakage rate from the tests above.


 * If a seal can't be used due to interference with door closing, the threshold gap should not exceed 3mm at any point.

FD30 Seal Configuration

 * One 20 x 4mm seal should be fitted centrally at the head and stiles, either in the door leaf or in the equivalent position in the frame or overpanel.
 * For double doors with flush meeting stiles, the same applies.

Double Door Rebated Meeting Stiles and Overpanel

 * Two 10 x 4mm seals should be used, one in each rebate.

Seal Interruptions

 * Intumescent seals can be fully interrupted in the leaf or frame edge by the dimensioned hinges and lock forend, as shown in drawing DRW14.

Metal Frame Installation

 * For door leaves installed in metal frames, follow the installation instructions provided by the frame supplier or manufacturer for intumescent seal specification and positioning.

Bolts for Inactive or Slave Leaves to BS EN 12051:2000
(Timber or metal frames)

Bolts are not necessary for Forza FD30 double doors. However, the extra restraint provided by bolts does have a beneficial effect. Unless Specific fire test evidence is available for use on timber doors and frames, all bolts shall be steel. The following limitations and protection apply;


 * Maximum size of flush bolt is 457mm long x 20mm wide and 25mm deep (relates to the deepest element of the bolt when in operation);
 * The head of the leaf and/or frame should contain intumescent material local to the bolt/keep plate;
 * The body of the bolt should be bedded on non-pressure forming intumescent material (e.g. Interdens) at least 1mm thick;
 * Edge fixed bolts shall be positioned centrally in the slave leaf thickness with the meeting style intumescent in the active leaf.
 * Flush bolts are not permissible on doors with rebated overpanels, since this will clash with the rebate alignment. Surface mounted bolts may be used; see below;
 * Face fixed flush bolts shall be fixed so that there is a minimum of 50mm between the bolt and the door edge;
 * Surface mounted barrel bolts shall not exceed 400mm in length, but there is no limitation on their width. Screws for fixing bolts must be at least 25mm long, and have thread for the full screw length. They shall be fixed so that there is a minimum of 50mm between the bolt and the door edge.

Pull Handles

Push / Kick Plates
(Timber or metal frames)

Plastic, pvc or metal plates may be surface-mounted to the door assemblies, but, if more than 800mm in length by nominally 200mm wide, they must be attached in a way that would prevent them distorting the door leaf, e.g. glued with thermally softening adhesive or screwed with maximum 12mm long screws at minimum 250mm centres and fitted in such a way so they will not be prevented from falling away by being trapped under door stops, glazing beads or handle escutcheons. Factory prepared recessed plates are permitted. Contact: tech@forza-doors.com

Identification Plates
to BS EN 5499-4 2013 (Timber or metal frames) Plastic or metal safety signs that comply with BS5499 may be glued or screwed to the face of the door leaf. A minimum 40mm spacing from leaf edge, hardware or vision panel(s) is required.

Letter Plates
