Fire stopping plays an essential role in passive fire protection by restoring the Fire Resistance Level (FRL) of openings created for building services. The Trafalgar Orange SuperSTOPPER® is a patented cast-in system designed to form neat, predetermined service openings within concrete floor slabs. Using internally fitted intumescent materials and a graphite-impregnated foam plug, the system helps prevent the spread of fire and smoke while reducing sound transmission and air leakage. It also eliminates oversized openings, simplifies service installation and provides valuable time, cost and safety benefits on site.

For those who may not be familiar, intumescent materials are widely used in passive fire protection. The dictionary definition of intumescent is as follows: An intumescent substance is one that swells when exposed to heat, resulting in an increase in volume and a decrease in density. Intumescence refers to the swelling process. Intumescent materials are typically used in passive fire protection, where the swelling is a chemical reaction that forms a char, which continues to expand and seals off openings.

Many people consider the cavity gap is just a control, movement joint, or linear gap seal and want to use the same fire resistance/fire testing data prescriptive (or deemed to satisfy provisions) regulations use for these control joints. Why can’t we, or can we? What is different with rainscreen cavity barriers joints to conventional control joints?A conventional control joint is a gap between two fire rated elements – example concrete to concrete. A horizontal cavity barrier joint is typically a gap between a.........

Without over complicating things, this ductwork needs to turn of automatically when a building is in fire mode. This is to stop the heating & air conditioning system spreading smoke to all parts of the building. Where the ductwork passes through a fire barrier, there is a requirement for a fire damper. A fire damper is a failsafe means of protecting these openings....
