摘要
The present invention relates to a fire stopping system comprising a flame-retardant heat-expandable tube rolled in a spiral form. The fire stopping system of the present invention can be applied to an opening formed in a partition structure such as a wall. If the fire stopping system of the present invention is applied, flames and toxic gas can be blocked so as not to diffuse through an opening in case of fire or the like, and thereby reduces damage to human life and property.
