Document Type and Number:
Japanese Patent JP2004508673
Kind Code:
A
Abstract:
A fire stopping faceplate assembly for an electrical box includes a faceplate having an inner surface, and a fire stopping mat arranged adjacent said faceplate inner surface. The fire stopping mat provides an active system which forms a fire barrier capable of preventing a temperature rise on the wall side opposite the fire by providing an endothermic material which withdraws heat and/or by expanding to provide additional insulating properties and otherwise stopping the spread of fire. The fire stopping mat may include an intumescent compound, an endothermic compound, or both an intumescent compound and an endothermic compound. The fire stopping mat may also include a layer of an infrared blocking material formed of, for example, a metal or a ceramic fiber material.
