In 2026, Fire-Rated Flexible Ducting is a non-negotiable life-safety component for any commercial or industrial HVAC installation. Under the Uniform Building By-Laws (UBBL) 2026 and the Fire and Rescue Department (BOMBA) Malaysia standards, terminal connections within ceiling voids must be constructed from materials that inhibit flame spread and minimize smoke toxicity. For developments in Kuala Lumpur and Selangor, maintaining a 5-Star BEI requires fire-rated systems that do not compromise on hermetic integrity or airflow efficiency.
At EKG (Malaysia) Sdn Bhd, we apply 34 years of mechanical engineering expertise to provide instrument-verified, fire-rated flexible ducting. We ensure your terminal connections are safe, compliant with MS 1525, and optimized for a 5-Star Building Energy Index (BEI).
Fire-rated flexible ducts are engineered to act as a barrier against the "Chimney Effect," where fire or smoke can travel rapidly through a building's ventilation paths.
Compliance with BS 476 Parts 6 & 7: Our ducts are rigorously tested to meet British Standard 476. Part 6 (Fire Propagation) ensures the material does not significantly contribute to the heat release of a fire, while Part 7 (Surface Spread of Flame) certifies that the duct jacket restricts the movement of fire across its surface.
Zero-Smoke Toxicity: In a fire event, smoke inhalation is often more dangerous than heat. We utilize Low-Smoke Zero-Halogen (LSZH) materials that do not emit toxic gases when exposed to extreme temperatures, satisfying the highest biosecurity and safety audits.
Lowering the BEI: Safety doesn't have to mean inefficiency. By utilizing High-Tensile Steel Wire Helixes, our fire-rated ducts maintain their shape under high static pressure. This prevents sagging and kinks that cause "Ghost Resistance," allowing your Variable Frequency Drives (VFDs) to operate at lower hertz and improving your Building Energy Index (BEI).
To meet SIRIM and BOMBA 2026 benchmarks, EKG utilizes a rigorous "Safety-First" handshake:
Our ducts feature a reinforced aluminum and polyester laminate core, specially treated with flame-retardant additives. This is encased in R-6.0 High-Density Non-Combustible Insulation (such as rockwool or glasswool) and protected by a fire-rated outer jacket. This construction ensures the duct remains structurally sound even when exposed to direct heat.
The connection between the flexible duct and the rigid branch must be as strong as the duct itself. We utilize Stainless Steel Band Clamps and BOMBA-certified fire-rated mastic to ensure a SMACNA Class C airtight seal. Where the duct passes through a fire-rated wall, we integrate it with BOMBA-approved fire dampers for absolute compartmentalization.
To ensure the fire-rated jacket performs as intended, the duct must be correctly supported. We strictly adhere to a maximum 2.5-meter length and utilize fire-resistant support cradles. This prevents the duct from drooping onto hot surfaces or electrical components, securing your 5-star safety rating.
| Performance Metric | Standard Flexible Duct | EKG Fire-Rated (BS 476) Flex |
| Flame Spread | Class 1 or 2 | Class 0 (BS 476 Part 7) |
| Heat Release | Unregulated | Low Propagation (BS 476 Part 6) |
| Smoke Profile | Potentially Toxic | Low-Smoke Zero-Halogen (LSZH) |
| Leakage Class | Class B | SMACNA Class C (Hermetic) |
| EECA 2024 Status | Regulatory Risk | Audit-Ready / 5-Star BEI Support |
Meeting Annual BOMBA Audits: For commercial high-rises in KL and Selangor, the Fire Certificate (FC) renewal depends on the proven performance of all ceiling-void materials. Our fire-rated systems include MS 1472 compliance reports that serve as technical evidence for your annual safety audit.
Lowering TNB Maximum Demand: By utilizing aerodynamically stable, fire-rated materials, we ensure your supply fans do not have to overcome the friction of deformed or collapsed ductwork. This secures your 5-star efficiency rating and lowers monthly costs.
Life-Safety & Liability Protection: Investing in BS 476-certified ducting is an investment in human life. Our systems provide the necessary time for evacuation and fire suppression, shielding building owners from the legal and operational liabilities of a fire event.
34 Years of Engineering Depth: Based in the Klang Valley, we are mechanical contractors who understand that in 2026, safety and efficiency are inseparable. We don't just "hook up" vents; we engineer the fire-safe and hermetic integrity of your infrastructure.
Turnkey Validation: We provide on-site Testing, Adjusting, and Balancing (TAB) and Smoke Simulation Tests to verify that your terminal connections meet the exact safety standards before commissioning.
Digital Twin Ready: We provide full 3D as-built data for your terminal connections, which can be integrated into your building's 3D digital twin for real-time facility management.
Is your terminal air delivery a hidden fire risk and energy waste, or is it a model of 5-star engineered safety? Contact EKG (Malaysia) Sdn Bhd today for specialized fire-rated flexible ducting solutions.
