Product Details

1. Wind Resistance: The roof panels of the "Roof Wall" system have a strong ability to resist both positive and negative wind pressure. Especially in the corner and edge areas of the roof, they are securely fixed with fasteners, which can withstand large wind loads.
2. Thermal Insulation: The polyurethane has a low thermal conductivity ranging from 0.019 to 0.024 W/m·K. It is a type of insulation material. The design ensures sealing performance and insulation effect.
3. Quick Construction: The panels are pre-manufactured in the factory, and the installation system is well-designed, meeting all-weather construction requirements. This can shorten the installation period, reduce labor costs and material wastage.
4. Sound Insulation: It has good sound insulation properties, reducing noise interference and effectively reducing the impact sounds of rain, ice mold, etc.
5. Excellent Thermal Insulation Performance: Using high-pressure continuous foaming technology, the foaming is uniform and dense, with low water absorption rate, effectively preventing water vapor penetration, and demonstrating thermal insulation and heat preservation performance.
6. Good Fire Resistance: The polyurethane hard foam has excellent fire resistance. When combined with metal surface materials, the flame retardant performance is further enhanced.
7. Environmental Technology: Using non-fluorine raw materials for one-time high-pressure foaming, no fluorocarbons are produced, and it is environmentally friendly.
8. Node Advantages: Hidden nail saddle fasteners are used for connection, with screws hidden for fixation; specially designed eaves and gable decorative shapes enhance the overall aesthetics and practicality.
