Envirograf Intumescent Fire Cages
Fire-rated, metal intumescent fire cages for lights and downlighters. Intumescent downlighter cages create a fire seal to maintain integrity as well as fire rating of a ceiling. Easily fitted from above or below in plasterboard or suspended ceilings. In the event of a fire, the intumescent expands to form a fire barrier, preventing fires from spreading rapidly.
According to fire statistics, overheated light fittings and electrical faults are a leading cause of fire destruction to buildings and homes. With buildings left unprotected, fire and smoke rapidly spread and destroy rooms and properties. Installing passive fire products for electrical services provides multiple benefits. Such benefits include compartmentalising fire, preventing fire spread and also preserving building structures. The intumescent material will expand to create a fire barrier, preventing fires from spreading. This allows occupants to safely evacuate a building and for fire rescue services to extinguish flames before they become severe.
Manufactured in a range of sizes to fit over various electrical fittings. An acoustic version is also available.
