Rock wool belongs inorganic A grade non combustible insulation material the safest choice for factory partition exterior wall fire isolation layer. It owns medium heat preservation performance and excellent sound absorption capacity suitable noisy production workshops. The fiber structure blocks flame spread to meet strict industrial fire audit standards, required by chemical paint and medical factory wall ceiling insulation projects.
PU and PIR foam insulation materials hold minimum heat transfer coefficient among all mainstream insulation products. Thin thickness can reach ideal heat preservation effect to reduce wall ceiling occupied space. PIR upgrades fire resistance based on PU fitting cold storage constant temperature cleanroom long term low temperature insulation demands. Long term use lowers refrigeration and heating equipment operating load largely to save energy cost continuously.
EPS foam insulation carries obvious raw material cost advantage for temporary warehouse simple workshop and low budget commercial auxiliary building wall ceiling. Light weight reduces wall ceiling load and speeds up construction progress. Fire resistance performance is limited only applicable low fire risk non core building structures forbidden chemical factory and sterile cleanroom main enclosure insulation layer.
Glass wool insulation material is lighter than rock wool with outstanding sound absorption performance suitable office commercial mall interior ceiling partition. Its fire rating reaches A grade but water absorption rate higher than rock wool cannot be used outdoor exterior wall and cold room wall insulation which easily loses heat preservation performance after damp infiltration and needs fully sealed sandwich panel wrapping for indoor use.
