Product Introduction
Seamless Polyurethane Exterior Wall Panels, also known as PU wall panels, are high-performance composite boards widely used in construction, cold chain, industrial and other fields. They consist of a rigid polyurethane foam core material with a closed-cell rate ≥95% and high-quality metal or non-metal surface layers. The panels feature industry-leading ultra-low thermal conductivity and adopt advanced continuous automated lamination technology to achieve molecular-level bonding between the core and surface layers. Their integrated design allows using thinner panels to meet building energy consumption limits, effectively saving construction space while ensuring stable quality and high production efficiency. These panels are ideal for exterior walls of villas, hotels, industrial plants and agricultural facilities, providing efficient insulation and durable protection.
Product Advantage
The rigid polyurethane foam core material has an ultra-low thermal conductivity of as low as 0.022 W/(m·K), leading the industry. Compared with traditional EPS foam, to meet the same insulation requirements, the thickness of our panels can be reduced by about 40%. This directly saves building space and transportation costs for customers. Tests by national laboratories show that cold storage or energy-saving buildings constructed with these panels can achieve a50%+ comprehensive energy-saving rate, significantly shortening the investment payback period.
The advanced continuous automated lamination process ensures strong molecular-level bonding between the polyurethane core and color steel/aluminum plate surface layers. The finished panels have a compressive strength ≥150 kPa and excellent flexural bearing capacity, with a bulk density controlled at 38-45kg/m³. This high-strength lightweight feature meets the structural needs of large-span factories and clean workshops, and significantly reduces the load on the main building structure. We provide a 20-year quality warranty to ensure no deformation or collapse during long-term use.
We focus on R&D of B1-grade flame-retardant and A-grade fireproof composite boards. Through a unique flame-retardant formula and patented technology, the panels pass strict fire tests. The production process uses an environmentally friendly fluorine-free foaming agent (cyclopentane system), making the product green and safe. It has obtained national fire test reports and green building materials product certification, suitable for fire-sensitive public buildings and environmentally demanding food and pharmaceutical workshops.
With a closed-cell rate ≥95%, the panels have extremely low water absorption, maintaining dryness and dimensional stability even in long-term high-humidity environments without insulation performance degradation. The panel edges adopt a unique tongue-and-groove interlocking structure, which, combined with special sealing tape, achieves seamless and tight splicing during installation. This effectively eliminates cold bridges and improves construction efficiency by over 30%. We offer standard modular products and customized cutting services for convenient construction.

Product Uses
As a core material for cold storage construction, the panels’ outstanding insulation and moisture-proof performance are suitable for various low-temperature facilities ranging from -25℃ to -60℃, including refrigerated warehouses, constant-temperature workshops and cold chain logistics distribution centers. The high energy-saving rate significantly reduces long-term operating costs, ensuring the integrity of the cold chain.
The panels are the preferred solution for energy-saving renovations of public buildings and industrial plants. They are especially suitable for exterior walls and roofs of electronic, pharmaceutical and food processing workshops, as well as data centers that require strict constant temperature, humidity and cleanliness. The integrated installation method builds a highly airtight enclosure system, improving the building energy efficiency grade and facilitating green building certification.
In large commercial spaces such as shopping malls and sports venues, the panels’ rapid installation shortens the construction period, and their diverse colors match architectural styles. In modern agriculture, they are used for insulation of livestock farms and flower cultivation greenhouses. The lightweight high-strength feature enables large-span structures, saving support costs and creating stable growth environments for animals and plants.
FAQ
Our standard polyurethane core material is B1 grade (difficult to ignite). For projects requiring A-level fire resistance, we offer polyurethane composite rock wool or glass wool boards, whose core materials are A-level non-combustible, fully meeting high-standard fire protection requirements.
The panels adopt a unique tongue-and-groove lap joint and internal lock design, paired with dedicated sealing tape. Tight splicing during installation forms a continuous insulation layer, physically eliminating cold bridges and ensuring the overall insulation effect.
No. With a closed-cell rate over 95%, the panels have excellent hydrophobicity and water vapor penetration resistance. They can remain dry and stable for a long time in humid environments, ensuring that insulation performance does not degrade over time.
Absolutely. We support custom cutting of non-standard sizes and offer a variety of surface material options, including color steel plates, stainless steel plates and aluminum-zinc plates. Different thicknesses and densities are also available to meet personalized project design requirements.
