Strengthened Structure for Enhanced Performance and Durability

Advanced Insulation Technology

Superior Thermal Insulation

The Duct Board Sheet (Double Sided Steel) utilizes advanced phenolic foam insulation technology to deliver superior thermal performance. With a low thermal conductivity and excellent insulating properties, it minimizes heat transfer and reduces energy loss, optimizing the efficiency of HVAC systems. The double-sided steel reinforcement enhances durability, providing long-term insulation performance.


Enhanced Fire Resistance

Fire-Safe Design

Safety is a top priority in HVAC systems, and our duct board sheet meets stringent fire safety standards. With a non-combustible A-class fire rating, it ensures the highest level of fire resistance. The sheet’s phenolic foam core and double-sided steel construction offer exceptional fire protection, minimizing the spread of flames and the release of toxic gases, ensuring the safety of building occupants.


Robust and Reliable

Durability and Performance

The phenolic Board Sheet (Double Sided Steel) is engineered for strength and durability. Its high-density core, reinforced by double-sided steel, provides excellent compression and bending strength, allowing it to withstand pressure and maintain its shape over time. The sheet’s resistance to wind, moisture, and dimensional changes ensures long-lasting performance in various environments.
