Longden timber doors can be supplied with
matching frames or as factory
Longden doorset frames can be 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. The below diagrams are show the standard frame
profiles available in relation to fire resistance performance.
Typically for exclusive home projects, frames and architraves are
supplied primed for on-site painting. Frames and architraves can
also be supplied in matching timber to complement the doors.
Sidelights and fanlights
Sidelights and fanlights can also be incorporated.
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.
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.
