The blue striped polyurethane insulation sandwich panel for exterior walls polyurethane insulated building panels is a composite panel that combines thermal insulation and decorative functions. It is mainly composed of color-coated steel plates (with a blue striped surface) as the face plate and polyurethane rigid foam as the core material. It is commonly used in the enclosure system of building exterior walls. composite insulation panels for construction Its core feature is that the low thermal conductivity of the polyurethane core material achieves high thermal insulation, while the outer blue striped steel plate provides aesthetic decoration and structural protection.

The core advantages of Blue Striped Polyurethane Insulation Sandwich Panels For Exterior Walls are:
1. Low Thermal Conductivity: The thermal conductivity of polyurethane rigid foam core material is extremely low. According to the domestic standard GB/T23932-2009, its optimal thermal conductivity is 0.018-0.025 W/(m²·K). The European standard EN14509 further requires a thermal conductivity coefficient (U-value) of ≤0.25 W/(m²·K) for thicknesses ≥ 80 mm. This characteristic allows the thickness of the panels to be significantly thinner than traditional materials for the same insulation requirements, effectively saving building space.
2. Advantages of a Closed-Cell Structure: The core material is primarily a closed-cell structure with a high closed-cell ratio. This not only blocks heat conduction but also reduces air convection and radiant heat dissipation, maintaining stable thermal insulation performance over the long term.
3. Fire-Retardant Properties: The product's combustion performance is determined by the organic binder content. The core material is a flame-retardant inorganic silicate fiber that self-extinguishes in the presence of an open flame. When burned, it only carbonizes, not dripping. The carbonized layer prevents air from entering and preventing fire from spreading, meeting building fire protection regulations.
4. Corrosion Resistance and Durability: The closed-cell structure and specialized surface material provide excellent resistance to air, moisture, acids, and alkalis, resulting in chemical stability and a long service life (when the surface material is painted with a highly weather-resistant polyester paint, the service life can reach over 20 years).
5. Watertightness and Moisture Resistance: The extremely low water absorption rate and the absence of seams and holes on the surface of the panels effectively prevent the infiltration of rainwater and moisture, preventing condensation on the walls and resolving the contradiction between traditional materials being "waterproof without insulation, or insulation without waterproofing" and "insulating without waterproofing" (conversely).
6. Lightweight, High-Strength, and Thin Design: As a structural material, the panels offer low overall weight, large spans, and high loads. Wide panels (e.g., 1000mm width) reduce installation joints and improve construction efficiency. For example, 60mm thick panels weigh only approximately 12.5kg/m², making them easy to transport and hoist.
7. Factory Prefabrication and Rapid Installation: Prefabricated on an industrial production line, quality is controlled, and the panels can be directly assembled and installed on-site. They support free-cutting and can be paired with blue striped decorative surfaces (e.g., rib stripes and pinstripe stripes). No additional painting is required, reducing construction time by over 30%.
8. Environmental Performance: The core material utilizes a CFC-free pentane foaming agent, which emits no harmful gases during production and use. Disposable and recyclable, it complies with green building standards.
9. Integrated Decoration and Function: The striped surface material (e.g., color-coated steel sheet) combines decorative and weather-resistant properties. The surface can be customized with various textures, including flat and pinstripe, to meet building facade design requirements. It also provides sound insulation and vibration absorption (airborne sound insulation up to 25dB).
Blue Striped Polyurethane Insulation Sandwich Panels For Exterior Walls application scenarios and application cases
1. Industrial Plants
Polyurethane sandwich panels offer significant advantages in industrial plant exterior wall applications. They provide excellent thermal insulation and, when combined with lightweight steel structures, embody the advantages of lightweight, efficient, and flexible layouts. Therefore, they have become the preferred solution for single-story plant construction. For multi-story industrial plants, polyurethane sandwich panels can also be used for flexible exterior wall layouts, enhancing the building's appearance through the varied colors and shapes of color-coated panels.
2. Public Buildings
Because public buildings have higher requirements than industrial plants, such as larger spaces, indoor air conditioning, and fire protection, blue-striped polyurethane insulating sandwich panels for exterior walls can meet these requirements for lightweight, thermal insulation, fire safety, waterproofing, sound absorption, and durability. For example, they can be used on the exterior walls of public buildings such as station waiting halls, stadiums, theaters and auditoriums, exhibition halls and convention centers, and museums.
3. Residential Construction
In the residential sector, polyurethane sandwich panels, due to their excellent thermal insulation properties, are widely used in walls, roofs, and other areas of newly constructed homes. With the increasing demand for living comfort and the increasing national requirements for building energy efficiency, the market demand for blue-striped polyurethane insulation sandwich panels for exterior walls in the residential sector will continue to grow. Furthermore, the renovation of older residential communities and the development of new urbanization will also create new growth areas for this product.
4. Temporary Buildings and Modular Housing
Striped polyurethane insulation sandwich panels for exterior walls offer a number of advantages, including light weight, flexible assembly, convenient and fast construction, no need for secondary renovation, and easy disassembly and relocation. Therefore, they are widely used in temporary buildings. The use of sandwich panels to construct additional floors is also common, expanding the usable area while addressing the insulation and waterproofing issues of the original roof.
