Phenolic thermal insulation board is an advanced rigid insulation material widely used in modern construction. Made from phenolic foam with a closed-cell structure, it offers low thermal conductivity, excellent fire performance, and long-term durability. Its unique composition makes it one of the most efficient and safest insulation products for energy-saving and fire-resistant buildings.

Key Features and Advantages

High Thermal Efficiency: Extremely low thermal conductivity (λ-value as low as 0.017–0.025 W/m·K), providing a high R-value with thinner boards.

Superior Fire Safety: Classified as Class 0 / Euroclass B-s1,d0, non-combustible, low smoke emission, no melting or dripping during fire.

Moisture Resistance: Closed-cell structure prevents water absorption, protecting insulation performance and avoiding mold growth.

Lightweight and Easy Installation: Easy to cut, handle, and install, reducing labor costs and project time.

Long-Term Durability: Maintains shape, insulation value, and stability throughout the building’s lifecycle.

Eco-Friendly: Low VOC emissions, contributes to green building certifications such as LEED and BREEAM.

Phenolic Insulation Board Applications

Roof Insulation: Flat and pitched roofs for residential, commercial, and industrial buildings.

Wall Insulation: External wall insulation (EWI), cavity wall insulation, and interior wall lining.

Floor Insulation: Suitable for ground floors, intermediate floors, and basement floors.

HVAC Systems: Used as pre-insulated duct panels and pipe insulation, ensuring thermal efficiency and fire safety.

Cold Storage & Cleanrooms: Reliable insulation in environments requiring stable temperature control.
