Sandwich panels are one of the commonly used building materials in the construction and industrial fields, which can provide functions such as heat insulation, sound insulation and structural strength. In BESINO’s wall enclosure system products, rock wool sandwich panels and polyurethane sandwich panels are two common product options. They have obvious differences in material composition, performance characteristics and scope of application.

Material composition

1. The rock wool sandwich panel consists of two parts: internal filler rock wool and external surface board. BESINO uses high-quality raw materials to produce and process non-combustible high-density hydrophobic rock wool. It uses high-quality basalt and diabase as raw materials, which are melted at high temperature, centrifugally pulled into fibers at high speed, and then added with a small amount of additives such as adhesives, dust-proof oils, and hydrophobic agents. It has excellent fire resistance, sound insulation and heat insulation performance, and can be recycled sustainably.

2. The material composition of polyurethane sandwich panels is different from that of rock wool sandwich panels. BESINO polyurethane sandwich panels use a new generation of polyurethane PIR pentane B1 foaming as a hard core material, which has excellent thermal insulation and fire resistance. It has ultra-high temperature stability and fire resistance level, no Freon emissions, energy saving and environmental protection, and can be widely used in industrial building cold storage projects.

Performance characteristics

1. In terms of thermal insulation, rock wool sandwich panels have a low thermal conductivity, which can effectively isolate the impact of outdoor high or low temperatures on indoor temperatures. Rock wool as a filler is not easy to burn and has high temperature resistance, which can play a good protective role in the event of a fire. The rock wool sandwich panels produced by BESINO are CE certified and have excellent flame retardant properties and safety.

2. The foam filling of polyurethane sandwich panels can provide better insulation effect, so that the building maintains a stable temperature. In addition, polyurethane has excellent bonding properties, which makes the overall performance of the sandwich panel more stable. BESINO polyurethane sandwich panels have excellent thermal insulation performance, superior mechanical properties, and low volatile organic compound (VOC) emissions, which are environmentally friendly and sustainable.

Scope of application

1. Rock wool sandwich panels are mainly suitable for building exterior wall insulation, roof insulation, industrial plants and other places that require high insulation and fire protection requirements.

2. Polyurethane sandwich panels are more used in cold storage, refrigerator trucks, food processing plants and other environments that need to maintain a stable low temperature. Its good airtightness and excellent thermal insulation performance enable it to effectively reduce energy consumption and maintain low temperature requirements.
