Experiments show that the PIR products can endure a temperature up to 200℃ in short time period or to 160℃ for long time. Comparing with common PIR rigid foam, it is well equipped with good thermal stability, excellent fire resistance, strong flame penetration resistance and low smoke generation.
1. Hidden screw type: Screw concealed, no exposed screws on the surface, the wall is beautiful and smooth
2. Energy saving and heat insulation: The closed cell rate is equal to or larger than 97% and the heat insulation performance is excellent.
3. Fire -resisting performance
4. Air tightness and sound insulation: The products have great sound insulation and decrease the sounds due to impacts of rainwater or hailstone.
5. Environment friendliness: Being free from formaldehyde and microorganisms,it can be recyclable.
6. Beautiful appearance and high economical efficiency: The products have diversifying surface forms and colors. Besides, they make less wastage, save both construction time and construction cost.
7. Quick construction: Customized according drawing at factory and quick construct at work site
8. Germany production line provide quality assurance: The panels have been applied for over 35 years.
9. VIP Service: 24h on line service, When the order is placed, it will be passed to production department immediately. There will be professional people inform the situation of the production from material preparation, mid-production, packing, loading, export documents preparing, after-sale service in time.
10. Fast delivery time: We have more than 6 manufacturing basements with more than 500 workers all over China which all near to the export port. The shortest time to port is 2 hours.
