Japans Asahi Kasei Launches Highperformance Phenolic Insulation Foam

In the pursuit of architectural energy efficiency and safety, the construction industry faces the challenge of balancing high-performance insulation with reliable fire protection. Asahi Kasei Construction Materials' Neoma Foam UF series presents an ideal solution - a non-combustible material specifically designed for RC (reinforced concrete) cast-in-place construction methods.

Neoma Foam UF is a composite insulation material featuring a Neoma Foam phenolic insulation board core with a single-sided inorganic board facing (paper-coated surface). Certified as a non-combustible material, it's specifically engineered for RC cast-in-place applications. Note that "Neoma Foam UF TM" will be discontinued in March 2025.

• Superior Thermal Performance: With a remarkably low thermal conductivity (below 0.020 W/(m·K)), the phenolic resin-based material effectively prevents heat transfer, reducing building energy consumption.
• Exceptional Fire Resistance: As a non-combustible material, it inhibits flame spread during fires, providing critical evacuation time and minimizing fire damage.
• Lightweight Yet Durable: Compared to traditional concrete or masonry, it reduces structural load while maintaining sufficient strength for safety and longevity.
• Efficient Installation: The cast-in-place method allows integration with concrete structures in a single pour, eliminating additional fasteners and shortening construction timelines.
• Environmental Compliance: Free from formaldehyde and other harmful substances, it meets green building standards for healthy indoor environments.

• Underground Parking Ceilings: Its non-combustible properties and thermal efficiency make it ideal for enhancing fire safety and comfort in parking structures.
• Exterior Insulation Systems: Effective for improving overall building insulation and reducing energy consumption.
• Seismic Isolation Pits: Suitable for insulation in seismic-resistant structures, ensuring stability and durability.

The standard cast-in-place installation involves:

1. Preparation: Ensuring template surfaces are clean and level
2. Panel Fixation: Securing Neoma Foam UF to templates using specialized fasteners ("Neoma Keeper II")
3. Concrete Pouring: Following standard concrete placement procedures with careful vibration to avoid panel damage
4. Curing: Proper concrete curing to ensure structural integrity

• Avoid mechanical damage during handling and installation
• Prevent moisture exposure and direct sunlight during storage
• Orient the inorganic board face toward the template side
• For reinforced insulation wall sections, follow specialized installation guidelines

All components meet stringent environmental standards:

• Insulation material: JIS A 9521 compliant (F☆☆☆☆ rating)
• Paper facing: Formaldehyde-free
• Inorganic board: Formaldehyde-free
• Adhesive: Non-formaldehyde based

• High Thermal Efficiency: Achieves thermal resistance of 2.5 [(m²·K)/W] at just 51mm thickness
• Non-Combustible Certification: Eliminates need for additional fireproof ceiling materials
• Space Optimization: Particularly valuable in fire-regulated spaces like parking facilities
• Weight Advantage: Lighter than traditional 12.5mm calcium silicate or gypsum boards, improving safety and installation efficiency
