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.
