Curtain wall insulation and fire protection system - Product

Curtain wall insulation rock wool boards are typically used with solid structures like concrete or brick as the base wall, and materials such as dry-hung stone or glass curtain walls as the facade. Rock wool boards serve as the thermal insulation layer between the base wall and the facade. They have excellent thermal insulation and fire resistance properties, high tensile strength, and sound-absorbing noise reduction capabilities, without causing corrosion to metal materials and components. The product is also breathable, allowing the wall to “breathe” freely. Additionally, it features convenient and efficient installation, with diverse facade options, integrating insulation, fire protection, and aesthetic appeal.
