Thermal Insulation Standards in Singapore: What Every Plant Needs to Know
Thermal Insulation Standards in Singapore: What Every Plant Needs to Know
Thermal insulation plays a critical role in maintaining process temperatures, protecting workers, and improving energy efficiency in industrial facilities across Singapore. As part of Singapore’s commitment to workplace safety and environmental responsibility, insulation work must align with local and international standards.
At Loonglobal Engineering, we don’t just install insulation — we ensure compliance with the latest codes and deliver peace of mind.
1. Singapore’s Regulatory Framework
In industrial construction, the Workplace Safety and Health (WSH) Act and specific MOM codes require that insulation work meets safety and material guidelines. In parallel, most oil and gas clients in Singapore also refer to:
ASTM (American Society for Testing and Materials)
ISO (International Organization for Standardization)
API standards (especially for tanks and piping)
2. Required Material Characteristics
For thermal insulation in hot systems, the following properties are typically required:
Thermal conductivity: Should be <0.045 W/m·K at 40°C
Fire resistance: Tested to BS 476 Part 6 & 7 or ASTM E84
Water absorption: Preferably <5% for weather-exposed lines
Materials like rockwool, calcium silicate, ceramic fiber, and aerogel blankets are commonly approved by EPCs and client consultants.
3. Installation Guidelines That Matter
A compliant insulation system must:
Maintain continuous coverage without gaps or air pockets
Include vapor barriers where needed (especially in cryogenic or dual-temperature systems)
Be properly sealed with jackets/cladding (aluminum, SS, GI)
Have removable sections for valves and flanges
We frequently audit existing systems where even minor lapses in jacketing lead to premature insulation failure and water ingress.
4. The Role of Certified Contractors
Many owners are unaware that insulation work — especially on Jurong Island — should only be conducted by bizSAFE STAR certified and MOM-licensed companies.
Loonglobal Engineering meets all current qualifications and is trained to comply with both plant-specific standards and ISO quality control systems.
5. Final Thoughts
Meeting Singapore’s thermal insulation standards isn’t just about ticking boxes — it protects your assets, people, and long-term OPEX. At Loonglobal, we ensure all works are documented, certified, and audit-ready for even the most stringent clients.
