Configurations
Both single and double door leaf arrangements are available and other options include overpanels, sidepanels, fanlights and sidelights. Double leaf assemblies should incorporate an aluminium or steel ‘T’ section on the leading edge of the primary leaf. This detail can also be provided on the leading edge of single leaf assemblies. We would strongly recommend that, wherever possible, all security doorsets open towards the likely direction of attack.
Frames
As standard, there is a choice of either the Mono Security, 94mm x 69mm solid hardwood rebated frame, with a minimum density of 600kg/m3 or the Solo Security, 110mm x 75mm manufactured from 14 gauge steel. Frames of increased section are also available on request.
Smoke seals
Where smoke control to BS 476 : Part 31.1 is required, combined intumescent smoke seals will be provided.
Vision panels
Small observation windows glazed with laminated antibandit or ballistic resistant glass are available as standard. The glass is normally retained by high security steel beads, with no fixings exposed on the attack face. As standard, the bead is supplied in a black powder coated finish, however a stainless steel finish is also available. Alternative glazing materials available include toughened polycarbonate and 19mm Pyrosec glass – the latter being particularly suitable for secure accommodation such as seclusion rooms.
The standard vision panel size (reference VB1) is 300mm square, giving a clear viewing size of 230mm x 230mm. We suggest that security vision panels are kept as small as possible, with maximum clear viewing width of 250mm. Fire resisting security glazing is available on request.
Ironmongery
Hinges and hinge bolts
High security doors are hung on a minimum of 11/2 pairs of J602BP hinges, with 1 pair of HB2 hinge bolts fitted as standard.
Lock arrangements
When deciding on lock specifications, the level of security and usage should be carefully considered. Obviously, multiple locking points greatly enhance overall performance of the assembly, although in many situations this is either unnecessary or impractical, for example with communal entrances.
The following are suggested lock specifications but for situations not covered by these examples or for more detailed advice, please contact our Technical Services Department.

ASSA 765 sash lock (70mm backset) with 35 33 56 striking plate, 601* cylinder, 256 accessory pack, with thumbturn, and ASSA 6650 lever furniture.

Installation
Recommended fixings for brickwork or concrete are Fischer FUR 10T (or Fischer FUR 10SS for steel frames) or Hilti HRD 10 (minimum 70mm anchorage into wall). These can also be used for new brickwork and blockwork, or wall cramps can be built-in. There must be a minimum of 5 fixings per jamb, staggered within the stop and rebate, at a maximum 450mm centres. Double leaf frames should include at least two fixings in the head. Leaderflush Shapland recommend you discuss your fixing requirements with our Technical Services Department.
