In the 2026 Malaysian regulatory landscape, EECA 2024 Compliant Thermal Jacketing is no longer just a best practice—it is a mandatory technical requirement for designated energy consumers. For commercial buildings and industrial facilities in Kuala Lumpur and Selangor, the Energy Efficiency and Conservation Act (EECA) 2024 requires a verifiable reduction in energy intensity.
At EKG M&E Sdn Bhd, we engineer thermal jacketing systems that serve as a robust vapor barrier and thermal shield, ensuring your HVAC infrastructure supports your building’s 5-Star Energy Intensity Label.
The EECA 2024 framework relies on the updated MS 1525 (Code of Practice on Energy Efficiency). Compliance requires that thermal jacketing maintains the design R-value of your insulation throughout its service life.
R-Value Preservation: In Malaysia’s 80% relative humidity, moisture ingress is the primary cause of R-value degradation. EECA-compliant jacketing must be hermetically sealed to prevent "Thermal Bypass" and "Wicking."
Vapor Permeance: We utilize jacketing materials with a permeance rating of less than 0.02 perms. This prevents the 33°C ambient humidity from driving toward the 12°C duct surface, ensuring the insulation remains bone-dry and efficient.
We implement a tiered jacketing approach based on the environmental exposure of your ductwork:
Aluminum Cladding (0.5mm to 1.0mm): The definitive solution for outdoor risers and rooftop ducts. It provides superior UV stability and mechanical protection against monsoon rains and maintenance foot traffic.
Multi-Layer Laminate Jacketing: A high-tech, self-healing alternative to traditional foil. It offers excellent puncture resistance and is ideal for tight indoor plenums where rigid metal cladding is difficult to install.
Non-Metallic PVC Jacketing: Utilized in corrosive environments or visible indoor areas. It is impact-resistant, easily washable, and meets BOMBA Class 0 fire safety requirements.
Implementing EECA-compliant jacketing provides a measurable improvement to your facility's energy profile:
BEI Reduction: By preventing thermal gain in the air distribution network, you can lower your BEI by 10 to 15 points. This is often the critical margin needed to move from a 3-Star to a 5-Star Rating.
TNB Peak Demand Management: Optimized thermal integrity ensures that chilled air reaches the zones at the design temperature. This allows your chillers to operate at more efficient setpoints, directly reducing monthly Maximum Demand charges.
DOSH IAQ 2026 Validation: By eliminating surface condensation, our jacketing prevents the mold colonization that leads to failures in mandatory 2026 biological contaminant audits.

Total 3D BIM Coordination: We model every jacketing transition and support bracket in 3D to eliminate "Thermal Bridges" (uninsulated gaps) during the design and installation phases.
Turnkey REM Support: We provide the thermal calculation reports and material certifications your Registered Energy Manager (REM) needs for official Suruhanjaya Tenaga (ST) submissions.
34 Years of Engineering Depth: Based in Kuala Lumpur, we specialize in the unique psychrometrics of the Malaysian climate and how to synchronize your hardware for maximum efficiency.
