Fireproof PU Insulation Sandwich Panel

 

Fireproof PU Insulation Sandwich Panel

It is a high-performance ventilation duct product, which is widely used in HVAC systems. The following is a detailed introduction:

 

Basic Structure: It is a sandwich structured panel. The core is Polyurethane(PU) foam, which is a closed-cell insulating material. The two outer layers are aluminum sheets or aluminum foils.

 

Panel Structure: Silver Alu. Foil/ PU Foam/ Silver Alu. Foil
Foam Density: 40-45kg/CBM
Panel Dimension: 3950mm*1200mm*20mm
Alu. Foil: 60 or 80 Micron (Embossed)
Fire Rating: Class 0 (BS476Part 6&7)

Excellent fire resistance and flame retardancy, with high safety factor. The core material is self-extinguishing, and after adding flame retardants, it will go out upon encountering fire. During combustion, it forms a carbon layer to block oxygen, and releases no harmful gases with low smoke and toxicity. The regular model meets the national standard B1 level, and the customized A-level model can meet the fire protection requirements for high-rise buildings and complies with the fire protection specifications of "Application Technology Standard for Metal-faced Sandwich Panels" JGJT 453-2019.

It has leading thermal insulation and energy-saving performance. The thermal conductivity of the core material is among the best among insulation materials, being only half that of EPS. It can effectively reduce the heat transfer in buildings, meet the energy-saving requirements of the new "Near Zero Energy Building Technology Standard", and significantly reduce the operating energy consumption of the building's HVAC system.

The structure is stable and moisture-proof, with a long service life. The bonding strength between the core material and the metal panel is high, and the overall wind pressure resistance and bending resistance performance are excellent, suitable for large-span steel structure buildings; the water repellent structure with a closed-cell rate exceeding 90% ensures that it does not absorb water or get damp, and its performance does not deteriorate in a humid salt spray environment, with a service life far exceeding that of traditional insulation boards.

Lightweight and high strength, friendly to structural loads. The core material density is only 40-50 kg/m³, much lighter than insulation core materials such as rock wool, significantly reducing the load requirements of the building structure. At the same time, the overall compressive and tensile strength of the panel is excellent, ensuring both construction safety and the stability of the building structure.

Modular production. With a wide range of specifications and customizable options, on-site only requires assembly and installation, without the need for complex procedures, significantly shortening the construction period of the building.

Lightweight and easy to transport. The product is lightweight per unit weight, eliminating the need for large equipment during transportation and lifting. This not only reduces labor and equipment costs during transportation and construction, but also lowers safety risks during the construction process.

Maintenance is simple. The metal panels are resistant to weathering and corrosion, easy to clean and repair. The core structure is stable and does not crack or deform. Daily maintenance only requires a simple inspection, and there is no need for frequent upkeep.

Energy conservation and consumption reduction. Excellent thermal insulation performance can continuously lower the energy consumption costs of building HVAC systems, while reducing the thickness of the walls can increase the usable indoor area. The long-term overall cost performance is outstanding.

Compliant with international standards, with a wide coverage of export markets. The products can obtain the EU EN14509 CE certification, the Australian AS4964 asbestos-free test and the AS1530 fire resistance test, meeting the market entry requirements of different regions such as Southeast Asia, Europe, and Australia, and adapting to the diversified needs of foreign trade exports.
Driven by industry trends, high-end demand has rapidly increased. The global demand for modular construction and weather-resistant fireproof PU core panels has grown by 25% annually, and the market share of high-end products continues to expand.
The standard system is well-established, ensuring product quality. There are clear product standards and testing regulations both domestically and internationally. The domestic national standards, EU EN standards, and Australian AS standards have formed a complete quality assessment system, which urges enterprises to improve product quality and ensure the compliance of products in various markets.
