Service risers are the lifelines of any multi-storey development, carrying critical electrical, hydraulic, and mechanical services. However, they also represent a significant risk for vertical fire spread. At True Seal, we provide high-performance Fire Board for Risers, creating a robust fire-rated enclosure that maintains compartmentation across every level.
Protecting the Backbone of Your Development
A compliant riser shaft must do more than just hide pipes; it must provide a certified Fire Resistance Level (FRL) typically 120/120/120 to protect the building’s structural integrity and the safety of its occupants.
Our shaft wall systems are designed for:
- One-Sided Installation: Essential for tight riser spaces where access is only available from one side.
- Service Integration: Seamlessly accommodating complex penetrations for HVAC ducts, copper piping, and electrical busways.
- Acoustic Performance: Reducing “riser noise” in high-end residential and commercial towers.
Technical Specifications: Riser Boarding
We utilise industry-standard systems from Knauf and CSR (such as Shaftliner™) to deliver lightweight, high-performance fire separation that doesn’t compromise on floor space.
| Feature | Standard Riser Wall | True Seal High-Performance Shaft |
| Typical FRL | 60/60/60 | Up to 120/120/120 |
| Installation | Two-Sided Access Required | One-Sided “Easy-Build” Systems |
| Moisture Resistance | Low | High (Suitable for early-stage construction) |
| Material | Standard Fire-Shield | High-Density Calcium Silicate / Gypsum |
Why Developers Partner with True Seal
For developers, the goal is clear: Risk Mitigation. A failed fire audit on a riser shaft can delay a project’s Certificate of Occupancy by months.
- Speed of Construction: Our riser boarding systems are engineered for rapid installation, allowing following trades (plumbers and electricians) to move in sooner.
- AS 1530.4 Compliance: Every shaft wall we build is strictly installed to manufacturer specifications, ensuring it meets the Australian Standard for fire resistance.
- Comprehensive Sealing: We don’t just build the walls. We provide the Service Penetration Sealing (fire collars, pillows, and mastics) to ensure the entire riser “envelope” is fire-tight.
