Firessak's parent company, Large Co., Ltd., launched in March 1998, initially focusing on manufacturing industrial fabrics with a specialization in heat-resistant materials. Over the years, it has evolved into a leading innovator, developing and producing cutting-edge materials, automotive components, and finished products. Large Co., Ltd. is renowned for its automotive insulation, sound-absorbing parts, and lightweight, durable composite materials.

In 2019, Firessak responded to a request from the fire department by developing a domestic fire suppression blanket specifically designed to address fires related to electric vehicles and Li-Ion batteries. Firessak aims to establish a new benchmark for fire suppression blankets with its exceptional heat resistance performance.

Firessak is the first domestic brand of fire suppression blankets to receive disaster safety certification, innovation product certification, and G-PASS company designation. It is the only fire suppression blanket recognized by the state for its quality.

Committed to continuous improvement through ongoing research and development, Firessak strives to provide advanced fire suppression solutions, positioning itself as the global standard for fire suppression blankets.
