High-Temperature Fire Rated Duct Seals by EKG M&E Sdn Bhd

In the fire safety infrastructure of Kuala Lumpur and Selangor, the weakest point of any fire-rated system is the joint. High-Temperature Fire Rated Duct Seals are specialized intumescent and silicone-based materials engineered to maintain the airtight and fire-proof integrity of a duct network during a thermal emergency. EKG M&E Sdn Bhd utilizes only certified, industrial-grade sealing solutions to ensure your system meets the 2-hour fire resistance required by BOMBA and the Uniform Building By-Laws (UBBL).

The Engineering of Active Fire Containment

Standard silicones and mastics will dry out, crack, or ignite when exposed to extreme heat. Fire-rated seals are designed to perform under stress through two primary mechanisms:

1. Intumescent Expansion

Where a duct penetrates a fire-rated wall or floor, we utilize Intumescent Sealants.

• The Expansion Gap: When temperatures rise above 150°C, these seals expand up to 25 times their original volume.

• The Char Barrier: This expansion creates a high-pressure, non-combustible "char" that physically plugs the gap between the duct and the structure. This is critical for blocking toxic smoke and flames from "leaking" into the next building compartment.

2. High-Temperature Elasticity

For the joints between duct sections (flanges), we utilize specialized gaskets and sealants that maintain their bond at temperatures reaching 250°C to 400°C.

• Integrity: This ensures the duct remains smoke-tight even as the metal expands and warps under thermal load.

• Liquid-Tight Seals: Essential for Kitchen Grease Exhaust, these seals prevent liquified fat from escaping the duct during a "flash fire," which could otherwise ignite the ceiling void.

Critical Operational & Energy Benefits

As a BOMBA-Compliant M&E Specialist, EKG ensures your duct sealing supports building efficiency:

• TNB Energy Efficiency (Leakage Elimination):

  Airtightness is the foundation of energy efficiency. By utilizing precision-applied, high-integrity seals, we eliminate "whistling" and air loss. This allows your Variable Frequency Drive (VFD) to maintain required airflows at lower frequencies (Hz), resulting in a lower monthly TNB electricity bill.

• EECA 2024 & Building Performance:

  Under the Energy Efficiency and Conservation Act (EECA) 2024, maintaining high-efficiency mechanical systems is mandatory. Our precision seals prevent the leakage of conditioned air, helping you achieve a lower Building Energy Index (BEI).

• IAQ & Odor Control:

  In mixed-use developments in KL, keeping odors contained is vital. Our high-temperature seals ensure that kitchen smells and industrial fumes are transported directly to the discharge point without escaping into office or residential areas.
