In the fast-paced construction environment of Kuala Lumpur and Selangor, structural constraints often dictate the choice of mechanical systems. Self-Supporting Fire-Rated Ductwork refers to specialized ducting systems constructed from high-strength, fire-rated boards (such as calcium silicate or vermiculite) that do not require an internal steel duct to maintain their shape or fire integrity. EKG M&E Sdn Bhd specializes in the engineering and installation of these high-performance systems, ensuring full compliance with BOMBA and the Uniform Building By-Laws (UBBL).
Unlike "clad" systems that wrap a steel duct, self-supporting ducts are the air conduit and the fire barrier combined into one single, lightweight assembly.
Our self-supporting assemblies are certified to provide 120 minutes of protection across three critical criteria:
Stability: The boards are engineered with high mechanical strength to resist buckling or collapse, even under the intense thermal stress and air pressure of a fire event.
Integrity: The precision-machined joints and specialized fire-rated adhesives ensure the system remains smoke-tight, preventing toxic fumes from breaching fire compartments.
Insulation: The material itself has extremely low thermal conductivity. This ensures the exterior of the duct remains cool enough to prevent the spontaneous ignition of nearby materials (like data cables or wood) outside the fire zone.
Moisture & Humidity Resistance: Essential for the Malaysian climate, the inorganic boards we use are resistant to rotting, mold, and degradation, even in high-humidity areas like basements or plant rooms.
Lightweight Construction: Because they eliminate the need for heavy steel inner linings, self-supporting ducts place less stress on the building's structural frame, which is ideal for retrofits or high-rise developments.
Space Optimization: These systems can be installed with "zero-clearance" to walls or floors, maximizing the available ceiling height in crowded KL commercial spaces.
As a BOMBA-Compliant M&E Specialist, EKG ensures your self-supporting infrastructure supports building efficiency:
TNB Energy Efficiency (Thermal Performance):
Self-supporting board systems have inherent thermal insulation properties that far exceed uninsulated steel. By minimizing heat gain/loss from unconditioned ceiling voids, your Variable Frequency Drive (VFD) can maintain required airflows at lower frequencies (Hz). This directly reduces your monthly TNB electricity bill.
EECA 2024 & Building Compliance:
Under the Energy Efficiency and Conservation Act (EECA) 2024, efficient mechanical transport is mandatory. The airtight construction of these assemblies prevents the leakage of conditioned air, helping you maintain a lower Building Energy Index (BEI).
Acoustic Dampening:
The dense, fibrous nature of fire-rated boards provides natural sound absorption. This reduces the noise generated by high-velocity smoke extract fans, creating a quieter environment for building occupants.
| Feature | Steel Duct with Fire-Wrap | EKG Self-Supporting Board Duct |
| Material Base | GI Steel + Mineral Wool | Calcium Silicate / Vermiculite Board |

Total 3D BIM Coordination: We utilize 3D modeling to coordinate these rigid assemblies with other building services, ensuring a "clash-free" installation that respects the structural integrity of the building.
Turnkey BOMBA Submission: We provide all necessary material data sheets and "Certificate of Conformity" documents required for Fire Certificate (FC) applications and annual renewals.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional self-supporting ducting services for data centers, shopping malls, and hospitals across Malaysia.
