Intumescent fire box / bag

Burning paper and liquids put through letter flaps in doors and walls can have devastating consequences, especially if premises are occupied. The number of nocturnal arson attacks on homes has increased lately and this is particularly worrying for domestic residents. They can now go to bed with the assurance that an Evirograft ® product protects their letterbox, and business owners can have the confidence that their commercial premises are guarded against damaging and disruptive letterbox attacks. The product is available as an internal rigid metal box or as a flexible glass-cloth bag with intumescent properties.
