In the 2026 Malaysian industrial sector, a Class 0 Fire Rating for AHU internal linings is a non-negotiable statutory requirement. Under BOMBA (JBPM) 2026 life-safety codes and the Uniform Building By-Laws (UBBL), the air distribution system is classified as a "Fire Highway." If the internal lining of an AHU is combustible, it can act as a fuel source, spreading flames and lethal toxic smoke throughout a building within minutes.
At EKG (Malaysia) SDN BHD, we ensure your units are equipped with Class 0 Certified linings that satisfy both fire safety and the thermal requirements of the Energy Efficiency and Conservation Act (EECA) 2024.
A Class 0 rating is the highest safety standard for surface spread of flame and fire propagation.
BS 476 Part 6 (Fire Propagation): Measures the amount of heat the lining releases when exposed to fire. Class 0 materials must demonstrate extremely low heat release to prevent the AHU from becoming a "furnace" during a fire event.
BS 476 Part 7 (Surface Spread of Flame): Measures how quickly a flame travels across the surface. Class 0 ensures the flame spread is effectively "zero," preventing the fire from moving from the AHU into the ductwork.
Annual Fire Certificate (FC): JBPM officers verify the fire-retardant markings on AHU internal components during annual walkthroughs. Non-compliant linings (such as standard non-rated foams) can lead to the immediate revocation of your FC.
We utilize advanced materials that balance life safety with thermodynamic performance.
| Material Component | Technical Specification | Engineering Purpose |
| Class 0 Elastomeric Foam | Nitrile Rubber (NBR) with alumina trihydrate. | Provides high $R$-value and acoustic damping while remaining self-extinguishing. |
| Glass-Cloth Facing | Inorganic, non-combustible textile weave. | Acts as a "Fire Shield" over the insulation, preventing ignition from spark or heat. |
| Intumescent Sealants | Fire-rated MS Polymers that expand when heated. | Seals panel joints to prevent smoke from "leaking" out of the AHU Box. |
| Mechanical Fasteners | Stainless steel pins with fire-rated washers. | Ensures the lining does not "slump" or fall during high-temperature events. |
A fire-rated lining must survive the mechanical stresses of a life-safety event.
Automatic Fire Signal AHU Shut-off: When the fire alarm triggers, the VFD-driven AHU undergoes a sudden, high-torque deceleration or shut-off. The Class 0 lining must be bonded with industrial-grade, heat-resistant adhesives to ensure it does not delaminate under the resulting pressure surge.
Smoke-Tight Integrity: By achieving SMACNA Seal Class A through specialized fire-rated gaskets, we ensure that if smoke enters the unit, it is contained within the casing and not "leaked" into the plant room or ceiling voids.
Low Smoke Toxicity (LST): Beyond just resisting flames, our 2026-spec linings are engineered to produce ultra-low levels of smoke. This ensures that the building's "Respiratory System" does not become a delivery mechanism for toxic fumes.
At EKG (Malaysia) SDN BHD, we ensure fire safety does not compromise energy health.
Thermal Bridge Factor (TB2): Our Class 0 linings are selected for their high thermal resistance. This prevents "Cold Bridging" and exterior sweating, maintaining your Building Energy Intensity (BEI).
Antimicrobial Surface: Every fire-rated lining we install is treated with silver-ion technology. This prevents the bio-film growth that leads to DOSH (JKKP) 2026 violations, ensuring the air path remains sterile.
Fiber-Free Guarantee: We avoid legacy fiberglass (which can become brittle and lose its fire-retardant binders). Our modern foams are 100% fiber-free, satisfying MS 1525:2024 IAQ standards.
Technical Integrity: We are mechanical and T&C specialists, not just general insulators. We understand the complex life-safety logic of modern HVAC systems.
Audit-Ready Reporting: Following the installation, we provide a Fire Rating & Material Certification Report, complete with SIRIM/BOMBA certification copies for your Fire Certificate (FC) records.
GITA Sustainability: Upgrading to high-efficiency, fire-rated linings is a recognized "Green" intervention. We provide the data for your 100% Green Investment Tax Allowance (GITA) claims.
