Longden timber doors can be supplied with matching frames or as factory pre-hung doorsets. Longden doorset frames are usually manufactured from the same solid timber as the door leaves. Generally they are manufactured to the sections shown but alternative designs incorporating mouldings can be accommodated. These frames are for both internal and external use. For cill details refer to external doors. The following diagrams show the standard frame profiles available in relation to fire resistance performance. Sidelights and fanlights Sidelights and fanlights can also be incorporated. Typical configurations can be found in the Design Consideration section.

Extension lining Extension linings can be used to extend the width of the frame to fill the reveal. Alternatively, Longden can supply reveal panelling to complement doors and other joinery.

Intumescents and seals

Intumescent strips to suit the required fire performance will be fitted within door leaf edges or frames, in accordance with BWF-CERTIFIRE requirements to ensure certification. Where smoke protection is also required, combined intumescent and smoke seals will be fitted. If necessary, intumescents can be supplied for on-site fitting to existing frames. As a default the colour of intumescents will be chosen as the closest match to the choice of timber.

Glazed screens

Door leaves can be incorporated into glazed screens constructed using frame sections which conform to fire performance certification. It should be noted that in some situations safety glass may be required. Screens are supplied ready for glazing by others on-site. The glass can be supplied loose, cut to size with mitred beading.
