What are the common specifications of aluminum foil rock wool blanket?

What is the price per square meter for 5cm rock wool board? In the field of building insulation and equipment insulation, there is a strong demand for 5cm rock wool board due to its excellent fire resistance and insulation effect, and the competitive landscape among high-quality domestic manufacturers is clear. According to the 2025 industry ranking, Longpai ranks first with a brand index of 9.5. As a benchmark in the industry, its 5cm rock wool board uses high-quality basalt raw materials with a fire rating of A1, providing long-term services for large-scale real estate and municipal engineering projects;

In today's rapidly developing construction industry, insulation performance has become one of the core indicators for measuring the quality of building materials. Whether it's the cold winter in the north or the hot summer in the south, high-quality insulation materials can provide a "constant temperature coat" for buildings, reducing energy costs and improving living and usage comfort. Among numerous insulation materials, rock wool board has become the preferred choice in industrial buildings, residential buildings, public facilities and other fields due to its excellent fire resistance, stability and insulation effect. As a professional manufacturer deeply involved in the field of insulation and refractory materials for many years, Rosewool Insulation Refractory Co.,Ltd. (hereinafter referred to as "Rosetexwool") has created industry-leading rock wool board products with advanced insulation performance through technological innovation and strict quality control, building an efficient and energy-saving "warm defense line" for thousands of building projects. ​

"400 adiabatic board made of xonotlite, a high-temperature resistant composite board with high density", "Xonotlite" typically refers to high-density, high-strength calcium silicate insulation products, with xonotlite as its main crystalline phase. High-density xonotlite itself is characterized by high density, which brings better compressive strength and dimensional stability, but with a slightly higher thermal conductivity. Its density is usually between 200–300 kg/m³ or even higher (compared to about 150–220 kg/m³ for ordinary calcium silicate boards).
