What Are 25mm Sandwich Panels
If you’re new to construction materials, you might wonder what exactly a 25mm sandwich panels is and why it matters. Simply put, sandwich panels are composite building materials made up of three layers: two strong outer face sheets and a lightweight core in the middle. This core is usually made from materials like polyurethane foam, polystyrene, or mineral wool, which provide excellent insulation and structural support.
The 25mm thickness refers to the overall depth of the panel, including the outer layers and the core. This specific thickness strikes a balance between lightweight design and effective thermal insulation, making it a popular choice for many building projects. It’s thick enough to provide good energy efficiency but still thin enough to keep construction costs and installation time down.
Common face materials include galvanized steel, aluminum, or coated metal sheets, which offer durability and weather resistance. The core materials, such as polyurethane sandwich panel foam, provide superior insulation, helping reduce energy costs and maintain comfortable indoor temperatures.
At Shanghe, our 25mm sandwich panels are crafted with strict quality control and can be customized to fit your exact project needs. Whether you require specific face materials, core types, or panel sizes, we ensure every panel meets high standards for performance and durability. This makes Shanghe’s sandwich panels a reliable choice for energy-efficient and lightweight building solutions.
