Intumescent materials other than edge strips are used on fire resisting doors.
For example, thin sheet material can provide insulation and protection:
◆ behind hinge blades
◆ around mortise lockcases
◆ around concealed door closers
Intumescent pads can protect hinge positions. Various thicknesses are available e.g. 0.5 mm, 1 mm and 2 mm, all of which will offer protection to a greater or lesser degree.
Likewise, mortise lock/latch cases and strikes, and mortise-concealed closers usually need to be protected by intumescent gaskets. Seek advice as to the right product for the application.
