Firestopping & Penetration SealingElectricians, plumbers, and HVAC technicians constantly create holes in fire-rated walls and floors. You will need to seal these service penetrations using tested fire-stopping materials like intumescent acrylic sealants, fire collars (which crush melting plastic pipes during a fire), fire pillows, and fire-rated mortar.

Intumescent CoatingIntumescent paint is a specialized coating designed to protect structural steel from losing its load-bearing capacity during a fire. Under normal conditions, it looks like a standard decorative paint finish. However, when exposed to high heat (typically starting around 200°C to 250°C), a chemical reaction causes it to swell rapidly and form a thick, protective layer of carbonaceous char.

Duct FireproofingFireproofing HVAC ducts is essential for maintaining a building's fire compartmentation by preventing extreme heat and flames from destroying the metal ductwork and spreading to adjacent rooms. Crucially, it prevents structural collapse so that emergency smoke extraction systems can continue operating while occupants evacuate. Additionally, fire-rated insulation can protect critical cabling routed inside the ducts and often serves as a reliable, zero-maintenance alternative to mechanical fire dampers
