  1. Bespoke Doors

    Bespoke Doors

    B1. A timber doorset constructed in accordance with this appendix is considered a secure doorset for the purposes of requirement Q1. NOTE: The information in this appendix applies to doors of up to 1000mm wide and 2000mm high. Additional measures may be necessary for larger doorsets. Material B2. The doorset should be manufactured from solid or laminated timber with a minimum density of 600kg/m3. Dimensions B3. Door rails, stiles and muntins should be at least 44mm After rebating, frame components should retain at least 32mm of timber. B4. Any panel within the doorset should be at least 15mm The panel should be securely held in place. Beading should be mechanically fixed and glued in position. B5. The smaller dimension of each panel – which can be either the width or height of the panel – should be 230mm or less. Locks, hinges and letter plates B6. The main doors for entering a dwelling (usually the front doorset) should be fitted with a multipoint locking system that meets the requirements of:

    • PAS 3621 (key locking on both sides), or
    • PAS 8621 (non-key locking on the internal face), or
    • PAS 10621 (non-key locking on the internal face, but with an external locking override facility).
    If it is not practical or desirable to install a multipoint locking system, a mortice lock that conforms with one of the following standards can be fitted instead, with a surface-mounted rim lock that conforms to the same standard:
    • BS 3621 (key locking both sides), or
    • BS 8621 (non-key locking on the internal face), or
    • BS 10621 (non-key locking on the internal face, but with an external locking override facility).Between the locking points for the mortice lock and surface-mounted rim lock, the distance should be 400–600mm.
    B7. The non-primary doors for entering a dwelling (for example, back door or garage interconnecting doors) should be fitted with a multipoint locking system that meets the requirements of:
    • PAS 3621 (key locking on both sides), or
    • PAS 8621 (non-key locking on the internal face), or
    • PAS 10621 (non-key locking on the internal face, but with an external locking override facility). If it is not practical or desirable to install a multipoint locking system, a mortice lock that conforms with one of the following standards can be fitted instead, with two morticed bolts.
      • BS 3621 (key locking both sides), or
      • BS 8621 (non-key locking on the internal face), or
      • BS 10621 (non-key locking on the internal door face, but with an external locking override facility). The morticed bolts should have a minimum projection of 20mm, should be at least 100mm from the top and bottom corners of the door, and should avoid any door construction joints.
    B8. Hinges accessible from outside should incorporate hinge bolts. B9. Letter plates, where provided, should: a. have a maximum aperture of 260mm x 40mm, and b. incorporate a flap or other features designed to hinder anyone attempting to remove keys with sticks and/or insert their hand. NOTE: Letter plates meeting the requirements of the Door and Hardware Federation’s (DHF’s) technical specification TS 008:2012 have been shown to protect against the attacks mentioned above. Door limitation and caller identification B10. The main doors for entering a dwelling (usually the front door) should have a door viewer unless other means exist to see callers, such as clear glass within the door or a window next to the doorset. The same doorset should also have a door chain or door limiter. NOTE: In some situations a door chain or limiter is not appropriate, for example where a warden may need emergency access to residents in sheltered housing. Alternative caller-identification measures such as electronic audio-visual door entry systems can be used to identify visitors. Glazing B.11 Any glazing which, if broken, would permit someone to insert their hand and release the locking device on the inside of the door should be a minimum of class P1A in accordance with BS EN 356:2000. Double- or triple-glazed units need to incorporate only one pane of class-P1A glass.
