Fire Safety Store stocks both the intumescent mastic and fireproof foam.
The intumescent mastic can be used around door frames to fill small gaps. A skin applies where the mastic was placed and this expands up to the five its size during a fire. It can be used to fill gaps between 1mm and 60mm wide and is tested to BS476 part 22. You have a choice between standard colours with the intumescent mastic, however once the skin has formed you can also paint over it to match your decor.
The fireproof foam works similarly to the mastic but the foam can expand up to 40 times its original volume. This is recommended for use around windows as well as doors. The foam comes in an aerosol can but doesn’t omit gases or fumes in the event of a fire.
