Ji'nan Engineering Plank house is a house that is lapped up with color steel sandwich panels. The general engineering activity board room is made up of two layers of colored steel plates and core materials for continuous moulding of polystyrene, which is commonly known as foam board. This kind of movable board house is common, and it is mainly used in temporary dormitory or temporary office, farm market, newsstand, warehouse, etc.

一种就是以岩棉为材料的彩钢夹芯板，这种夹芯板相对聚苯乙烯夹芯板来说稍贵，但保温效果好，防火性能好，隔音效果也好，使用范围也广，另外一种是以硬质聚氨酯泡沫为芯材的新型保温材料，这种保温板称为聚氨酯夹芯板，

One is the color steel sandwich panel with rock wool as the material. The sandwich panel is slightly more expensive than the polystyrene sandwich panel, but its heat preservation effect is good, its fireproof performance is good, its sound insulation effect is good, and its application range is wide. Another kind is a new type of thermal insulation material with rigid polyurethane foam as core material, which is called polyurethane sandwich panel.

保温板的特点：不燃、防潮、防虫蛀、隔音、质轻、干湿不会变形、保温效果，并且可钉、可锯、施工简单方便，并且可以重复循环使用，而且该夹芯板不会出现裂纹、折断，且具有耐磨、表面质量平整光滑效果。在超低温下使用收缩小、不脆化，被广泛应用于简易活动房的屋面、墙体、空气洁净室的吊顶与隔断、厂房、仓库等大型建筑的屋面，更为适合建造冷库。如果活动板房采用这种夹芯板为搭接板材保温效果非常好，就是较贵。

The characteristics of the insulation board: non combustible, moisture-proof, mothproof, sound insulation, light weight, dry and wet will not deform, thermal insulation effect, and can be nailed, sawn, simple and convenient construction, and can be recycled, and the sandwich panel will not crack, break, and has wear-resistant, smooth surface quality effect. It is widely used in roof and wall of simple movable room, ceiling and partition of air clean room, roof of high-grade workshop, warehouse and other large-scale buildings. It is most suitable for building cold storage. If this kind of sandwich panel is used in the movable board room, the insulation effect is very good, that is, the price is more expensive.
