Phenolic Sandwich Panel

Phenolic sandwich panels are composite panels made of two layers of color-coated steel sheets with a phenolic foam core. These panels are suitable for roofs and walls, offering excellent thermal insulation, energy efficiency, and durability. Thanks to their fireproof and eco-friendly properties, they are widely used in prefabricated buildings, cleanrooms, and other high-safety environments.

Main Benefits of Phenolic Sandwich Panels

Fire Resistance: Phenolic foam is non-flammable, produces minimal smoke and toxic gases during a fire, and meets high fire safety standards.

Thermal Insulation: With a low thermal conductivity (as low as 0.018 W/m·K), these panels provide excellent insulation. They enable thinner panels to deliver the same thermal performance as thicker alternatives.

Lightweight and Easy to Install: Their lightweight feature facilitates easy transportation and installation. Their low density reduces overall building weight and supports quick, efficient assembly.

Structural Strength: The composite structure offers high pressure and shear strength, resisting wind loads and enhancing overall building stability.

Aesthetic Appeal: Available in various textures and colors, phenolic panels can be customized for different architectural styles. They also resist weathering, abrasion, and chemicals.

Phenolic Sandwich Panels: Common Uses

Structural Insulation Panels: Ideal for walls, roofs, and partitions in prefabricated buildings, container homes, and industrial facilities.

Roofing: Used to insulate steel-framed roofs, providing durable, attractive, and thermal insulation.

Special Environments: Suitable for clean rooms, refrigeration facilities, and food or beverage processing environments due to their cleanliness and insulation properties.

Transportation: With high strength-to-weight ratios and fire resistance, they are used in railroads, aircraft, and other transportation modes.

HVAC: Phenolic panels are commonly used in commercial and industrial ductwork, offering lightweight properties, low thermal conductivity, and enhanced fire safety.

Refrigeration: Due to its good temperature control, it is suitable for cold rooms and storage facilities.

Frequently Asked Questions

How does a phenolic sandwich panel compare to other insulation materials in fire performance?

Phenolic foams provide higher fire resistance than PUR, PIR, EPS, and XPS, with higher ignition temperatures and lower smoke emissions, making them suitable for fire-sensitive applications.

Are these sandwich panels suitable for outdoor use?

Yes, outdoor-grade phenolic panels are designed to withstand harsh weather conditions, including UV rays, rain, and extreme temperatures. Their surfaces resist fading, scratching, and impact, making them ideal for facades and exterior cladding.

How are phenolic sandwich panels installed?

Installation is quick and straightforward compared to traditional methods. The panels are mechanically fixed to the framework, and specialized tools, such as vacuum spreaders, assist with handling large panels. Joints should be sealed to ensure weather tightness.

Are phenolic sandwich panel walls easy to maintain?

Yes, phenolic panels are non-porous with smooth surfaces, making them easy to clean. They help prevent mold growth and can be cleaned with many common household cleaners, making them suitable for environments requiring strict hygiene, such as hospitals or commercial kitchens.

Can the size or finish of these sheets be customized?

Cowinlife manufacturer offers customization options for panel sizes, thicknesses, exterior surfaces, and finishes to meet various architectural needs.
