Polyurethane Sandwich Panel: High-Performance Insulated Building Solution for Wall & Roof
The polyurethane sandwich panel (PU/PIR) is a mainstream high-performance composite insulated building material widely used in global industrial, commercial and residential construction projects. As an upgraded alternative to traditional EPS sandwich panels, our insulated wall and roof panels integrate excellent thermal insulation, waterproofing, sound insulation and structural stability. Featuring lightweight design and fast installation, this prefab building material has become the preferred solution for energy-saving green buildings, cold storage engineering, steel structure workshops and container house construction.
Premium Core Structure & Raw Material Specifications
Our insulated sandwich panel adopts a double-layer metal surface + closed-cell PU/PIR foam core integrated structure, with strict standardized production to ensure overall durability and structural firmness.
1.Metal Facings: 0.3–0.8mm thick high-quality metal sheets, including pre-painted steel sheet, galvanized steel, aluminum sheet, stainless steel and anti-slip embossed panels. Multiple surface materials meet different anti-corrosion and scene usage needs.
2.Foam Core Material: High-density closed-cell PU/PIR core with a density of 40–45 kg/m³ and ultra-low thermal conductivity ≤0.0195 W/(m·K), far superior to ordinary EPS core material in insulation and compression resistance.
3.Integrated Molding Process: Adopts high-pressure injection seamless bonding technology, which effectively prevents panel delamination, peeling and water penetration, ensuring long-term stable performance in complex construction environments.
Excellent Thermal Insulation & Energy-Saving Performance
Thermal insulation is the core advantage of our polyurethane sandwich panel. Thanks to the ultra-low thermal conductivity of the closed-cell PU/PIR foam core, the panel can effectively block internal and external heat transfer. It can reduce the heating and cooling energy consumption of buildings by up to 40%, perfectly solving the high energy consumption problem of traditional building walls and roofs.
This high-efficiency thermal insulation panel is widely applicable to temperature-controlled buildings, including cold storage rooms, constant-temperature laboratories, clean rooms, and various LEED-certified green building projects, helping enterprises reduce operating costs and meet global energy-saving building standards.
Superior Waterproof, Moisture-Proof & Acoustic Insulation Properties
Different from ordinary insulated wall panels, our PU/PIR sandwich panel has dual advantages of waterproof and sound insulation. The fully closed-cell foam structure completely resists moisture absorption, and the seamless bonding process eliminates water ingress gaps. It performs excellently in high-humidity environments such as swimming pools, bathroom partitions and food processing plants, with no mildew or water leakage for long-term use.
In addition, the dense foam core has efficient sound absorption and noise reduction functions, which can effectively isolate indoor and outdoor noise and reduce inter-room sound transmission. It is an ideal wall and roof panel for hospitals, hotels, residential buildings and urban commercial buildings, adapting to various wet and noisy construction scenarios.
Lightweight, High-Strength & Fast Installation Design
Our color steel sandwich panel is lightweight but high-strength, with a weight of only 10–15 kg/m². Despite the light self-weight, it has excellent load-bearing and impact resistance, which can resist strong wind, snow pressure and minor external impacts without deformation or damage, meeting the structural safety standards of steel structure workshops and prefab buildings.
The panel adopts a professional tongue-and-groove hidden screw joint design, which realizes rapid splicing installation without complex construction procedures. It greatly saves labor costs and shortens the project construction cycle, significantly improving the delivery efficiency of prefab buildings, container houses and factory renovation projects.
Wide Application Scenarios of Insulated Sandwich Panels
Versatile and practical, our polyurethane sandwich panels cover almost all mainstream construction fields, supporting customized fireproof grades to adapt to high-risk scenarios:
1.Industrial buildings: Steel structure workshops, electronics factories, cleanrooms, industrial partition walls
2.Cold chain engineering: Low-temperature cold storage, frozen food warehouses, constant-temperature preservation rooms
3.Commercial & civil buildings: Hospitals, hotels, office buildings, residential wall and roof insulation systems
4.Prefabricated buildings: Container houses, temporary construction houses, mobile isolation rooms
Equipped with optional B1/B2 grade flame-retardant core materials, the panels meet international fire safety standards and can be safely used in high-flammability and high-risk industrial areas.
