iPick Co., Ltd., a partition manufacturer, will explain the definition of non-combustible materials under the Building Standards Act and their importance in office interiors. Fire-resistant materials are classified into three categories: non-combustible, quasi-non-combustible, and flame-retardant, based on safety during a fire. At iPick, we handle aluminum partitions that have received non-combustible certification, demonstrating high fire resistance, which is required by "interior restrictions" depending on the size and use of the building. Selecting appropriate materials is crucial not only for protecting the lives of employees but also from the perspective of asset protection and business continuity planning (BCP). We propose the creation of safe spaces that balance compliance with regulations and design. ＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊ For the design and construction of interior partitions from offices to toilet booths, leave it to iPick, the partition specialist manufacturer!
