Pre-insulated phenolic duct board is a next-generation HVAC ducting solution that combines thermal insulation, fire resistance, and lightweight construction in one product. Manufactured from rigid phenolic foam with aluminum foil facing, it eliminates the need for separate insulation layers, making installation faster, cleaner, and more cost-effective compared to traditional sheet metal ducts.

Key Features and Benefits

Excellent Thermal Performance

With an ultra-low thermal conductivity (λ-value: 0.017–0.025 W/m·K), pre-insulated phenolic duct boards ensure high R-value and superior energy efficiency.

Superior Fire Safety

Classified as B-s1,d0 under EN 13501-1, phenolic duct boards do not burn, melt, or produce dense smoke, making them ideal for safety-critical environments.

Lightweight & Easy Installation

Up to 40% lighter than traditional galvanized steel ducts, requiring fewer workers for transportation and assembly. Pre-fabricated panels reduce labor costs and speed up project schedules.

Moisture & Mold Resistant

Closed-cell phenolic foam prevents water absorption and condensation, ensuring long-lasting insulation performance and improved indoor air quality.

Space-Saving Design

Thinner boards provide the same insulation value as thicker alternatives, maximizing usable space in commercial and residential buildings.

Eco-Friendly

Low VOC emissions and CFC/HCFC-free foaming process make it a sustainable choice for green building certifications such as LEED and BREEAM.
