Product Overview & Core Advantages

Core Performance Advantages

 

1. Exceptional Fire Performance

• Our Fire-Rated PU Insulation Panels are formulated with advanced flame-retardant additives

• Achieve Class A fire resistance certified to EN 13501-1:2018 and ASTM E84-22a standards

• Unlike traditional EPS or XPS insulation: no melting, no dripping, no toxic fume release when exposed to fire

• Provide critical life safety protection for building occupants and structural integrity

2. Industry-Leading Thermal Insulation

• Ultra-low thermal conductivity: as low as 0.022 W/(m·K) at 25°C

• Deliver the highest thermal efficiency among all rigid insulation materials

• Achieve required insulation performance with thinner panels

• Save valuable building floor space and reduce overall material costs

3. Fast & Efficient Installation System

• Patented interlocking tongue-and-groove design for perfect, airtight joints every time

• Panels are prefabricated to your exact project specifications

• Eliminate on-site cutting, waste and wet work

• A 2-person crew can install up to 500 m² per day

• Dramatically shorten construction schedules and cut labor costs by up to 50%

4. Long Service Life & Zero Maintenance

• Inherent closed-cell structure: 100% moisture-resistant and vapor-impermeable

• Prevent mold growth, water damage and structural deterioration

• Maintain full insulation performance for over 50 years with proper installation

• Require no regular maintenance throughout their entire service life

• Deliver superior long-term value compared to traditional insulation solutions
