According to statistics from thecrimepreventionwebsite.com¹: “most domestic arsons (around 90%) involve the letter plate through which petrol or similar fuel is poured followed by a burning rag or firework”.

How Do Intumescent Letter Plates Work?

Intumescent products in general are designed to expand when they come in to contact with heat, acting as a sealant as a result. The same goes for Intumescent Letter Plates, as parts of the Letter Plate expand and swell, this seals off the opening of the Letter Plate. As well as serving the purpose of a regular Letter Plate, an Intumescent Letter Plate not only prevents a fire from being started outside of the home, but can also prevent a fire from spreading further.

How Effective Are Intumescent Letter Plates?

Standard Intumescent Letter Plates have a fire resistance time ranging from 30 to 60 minutes, which should be plenty of time for a safe evacuation process to take place without fire spreading any further than the original source. Some Intumescent Letter Plates can even be fitted to fire rated doors for even greater protection.

Intumescent Letter Plates don’t just protect a building from fires, they also offer protection against the smoke and harmful toxins emitted from a fire.
