Just like a hole in a ship is dangerous, so is a hole in a fire-resistant wall. Modern passive fire protection NSW revolves around the concept of compartmentation; i.e., to delay (or prevent) the spread of flames and smoke from one section of the building to another, the structure gets divided into many fire-rated compartments. Fire sealing penetrations NSW systems, such as Intumescent and silicone sealants, seals the penetrations found in structures during construction work, such as power cables, plumbing, ventilation ducts, movement joints etc., to improve the passive fire safety.
Why is Fire Sealing Protection NSW important?
In a structure, hidden spaces or cavities provide a ready path for the spread of smoke and flames. In every application, the importance of fire sealing penetrations NSW for any gaps in fire-resistant construction is vital to maximizing its ability to protect lives and property. Such breaches include penetrations through walls and floors, either due to inadequate craftsmanship, or left for structural movement.
Every service passing through fire-resistant building elements reacts differently in the event of a fire, so there is no single passive fire protection NSW solution that can protect all services. There are various standardized tests to decide.
Fire Collar for plastic piper penetration
Studies have shown that the different kinds of plastics behave in different ways under fire conditions. The plastic melts and burns away in case of a fire. Plastic pipes that penetrate compartment walls or floors or other fire barriers present a chance to the fire to move from one compartment to another. The fire rating of each section must not be affected by the facilities that pass through them.
Fire Collars are the most acceptable method against fire sealing penetrations NSW of plastic services. A fire collar is a kind of fire-resistant fitting that maintains the integrity and fire insulation of a building element that has been penetrated by plastic in the fire. It may be required, for example, when walls or floors get pierced by cables, ducts, pipework, etc.
Fire Collars are mostly surface mounted. The surface-mounted collars get fixed on the surface of the construction part around the plastic pipe. It is on the underside of the slab, for floor slabs. For walls, they are usually gets mounted on both sides; this way they protect against fire exposure from any direction.
Intumescent Acrylic Sealant
An Intumescent sealant seals gaps when exposed to flame and stop smoke from moving from one section to another. It is useful in sealing joints, small openings, and holes, as it is odourless and easy to paint.
Silicone Sealant
Silicone sealant is ideal for sealing small gaps and holes. It is also suitable for the weather-sealing of curtain walls, the construction of facades and fire-rated wall expansion joints.
Conclusion
Gaps are usually at service penetrations across walls and floors, but due to poor craftsmanship that can breach the overall passive fire protection NSW. To ensure that the device operates to its fullest potential to save life and property, the importance of sealing any holes in fire-resistant buildings is most vital.
