Polyurethane color steel sandwich panels are currently commonly used exterior walls and roofing materials for steel structure buildings. Today, I will introduce to you in detail the classification of polyurethane sandwich panels. According to the purpose, they can be divided into polyurethane wall panels and Polyurethane roof panels are divided into pure polyurethane composite panels and polyurethane edge-sealed fireproof panels according to their core materials. Polyurethane edge-sealed fireproof panels include polyurethane rock wool panels and polyurethane glass wool panels.
The following editor will give you a detailed introduction to these panels. First, we will talk about polyurethane edge-sealed rock wool board and polyurethane edge-sealed glass wool board. These two boards use rock wool and glass wool as the core material, and both sides are sealed with polyurethane. On the sides, the double-sided aluminum-zinc-plated color steel is used as the panel, and the thickness of the core material is usually 50-100mm. The more prominent advantage is that the fire resistance level is higher and reaches A level.
The pure polyurethane composite board uses polyurethane as the thermal insulation core material, and the double-sided aluminum-zinc color steel is used as the panel. The thickness of the core material is generally 50-100mm. However, due to the high thermal insulation effect of polyurethane and the concave-convex groove structure, It improves the insulation and air tightness at the joints of the board, so it is also used as a cold room panel, and the thickness of the core material is usually 100-200mm.
