Surface Material
Our PUR (polyurethane) / PIR(polyisocyanurate) seamless insulated exterior wall panels have multiple customizable surface steel material and color choices such as PPGI, Stainless steel, embossed aluminum etc. Their durability, moisture resistance and chemical resistance further enhance their appeal.
- PPGI
PPGI, or Preprinted Galvanized Iron, is a versatile metal material widely used in construction and manufacturing. It features a galvanized steel base that is coated with a layer of paint for excellent corrosion resistance and durability. Key features include its lightweight nature and its availability in a variety of colors and finishes for aesthetic customization. PPGI is also very environmentally friendly as its production process produces less waste. PPGI has a long service life and minimal maintenance requirements, making it ideal for roofing, wall cladding and other applications.

-Extra Coating
The surface material can also enhanced with various advanced coatings to improve its performance and durability.
Typical coating includes:
1. PVDF (Polyvinylidene Fluoride): Known for its exceptional resistance to UV radiation, chemicals, and weathering, PVDF provides a glossy finish that retains color vibrancy over time. This makes it ideal for outdoor applications, particularly in architectural projects.
2. HDP (High-Durability Polyester): HDP coatings offer superior durability and scratch resistance, making them suitable for high-traffic areas and industrial environments. They protect against corrosion and environmental factors, extending the lifespan of the material.
3. EP (Epoxy Polyester): This coating combines the benefits of epoxy and polyester, providing excellent adhesion and resistance to chemicals and moisture. EP coatings are ideal for indoor applications and environments where chemical exposure is a concern.
These advanced coatings significantly enhance the functionality and longevity of surface, making it a preferred choice for various applications in construction and manufacturing.
More About PUR/PIR Foam Core Exterior Wall Seamless Sandwich Panel
PIR/PUR seamless insulation exterior wall panels represent a major advancement in construction technology. Their combination of energy efficiency, moisture resistance, durability, aesthetic versatility, and ease of installation make them an attractive choice for modern building projects. As the demand for sustainable and efficient building solutions continues to grow, these panels will play a vital role in shaping the future of the construction industry. Whether new construction or renovation, sandwich panels offer a reliable and effective way to enhance the performance and appearance of any structure.
When installed in a cold storage facility, these panels create a barrier that minimizes heat transfer from the external environment to the interior space. This is critical to maintaining low temperatures, as even small fluctuations can cause temperature-sensitive products to spoil. The outer metal layer not only provides structural support but also protects the foam core from physical damage and environmental exposure.
Key features include:
1. Energy Efficiency
One of the most significant advantages of PIR and PU panels is their excellent thermal insulation capabilities. Rigid foam core has a high R-value, which means it effectively blocks heat transfer. This reduces energy consumption for heating and cooling, thereby lowering utility bills and carbon footprint.
2. Moisture-proof
PIR and PUR foam core itself is moisture-proof and helps prevent mold growth. This property is particularly beneficial in high-humidity climates or areas with easy access to water. The seamless design further minimizes the risk of water penetration, ensuring the building remains dry and comfortable.
3. Durability and Longevity
PIR and PUR sandwich panels are designed to withstand harsh environmental conditions, including extreme temperatures, UV radiation, and physical impact. Their sturdy construction ensures they maintain structural integrity over time, reducing the need for frequent repairs or replacements.
4. Aesthetic Variety
These panels are available in a variety of colors, textures, and finishes, allowing architects and builders to achieve the desired aesthetic for their projects. The seamless nature of the panels also contributes to a sleek, modern look that enhances the overall visual appeal of the building.
5. Easy to Install
PIR and PUR core foam seamless insulation sandwich panels are lightweight and easy to handle, simplifying the installation process. Their prefabricated nature allows for rapid assembly on site, reducing labor costs and construction time. Additionally, the seamless design minimizes the need for additional sealing or finishing work.
Frequently Asked Questions (FAQ)
What are the core materials used in these seamless sandwich panels?
The core materials used are Polyurethane (PUR) and Polyisocyanurate (PIR). They are rigid foam cores widely recognized for their exceptional thermal insulation properties, mechanical strength, and moisture resistance.
How does the seamless design improve building performance?
By eliminating joints and connections—which are common weak points in traditional wall systems—the seamless design prevents water penetration, reduces heat transfer, and improves the overall structural longevity and efficiency of the building.
What are the standard technical specifications of the PUR core panels?
Our panels feature thicknesses ranging from 100mm to 200mm, effective widths of 920mm to 1000mm, a core density of 40±2 Kg/m³, a B2 Grade fire resistance rating, and a low heat transfer coefficient of ≤0.024 W/[m x K].
What surface materials and coatings can be customized?
We offer a variety of surface materials including PPGI (Prepainted Galvanized Iron), Stainless Steel (SUS304/SUS201), Embossed Aluminum, and other alloys (Ti-Mg-Zn-Al). Protective coatings such as PVDF, HDP, and EP are also customizable to enhance durability.
Why are these panels suitable for cold storage facilities?
When installed in cold storage facilities, the rigid foam core creates an effective thermal barrier that minimizes heat transfer from the external environment. This maintains stable, low internal temperatures, preventing temperature-sensitive products from spoiling.
