Mr.Ha, from Korea, took the opportunity to visit Double Egret on September 17th. He is a senior expert in the field of fire doors and also an experienced engineer, whose enterprise is the largest manufacturer of fire doors in Korea, establishing branch offices all around the world. 

     Meanwhile, Mr.ha is also a knowledgeable and witty scholar, who always makes us laugh by something interesting while we have dinner. The purpose of his visit is to find if it is possible to use ceramic fiber board as fire door material. He hopes have some in-depth discussions with our engineer and then determines whether ceramic fiber board is available for fire door. Mr. Ha always used to adopt rock wool and calcium silicate board as fireproof material. With the development of environmental awareness in recent years, and a certain amount of formaldehyde in ceramic fiber, consumers prefer to use eco-friendly and harmless materials, which promotes fire door industry to replace rock wool with ceramic fiber board and other lightweight, eco-friendly and energy-efficient insulation materials.

     At present, many Chinese fire door enterprises have started using ceramic fiber board as fire doors refractory material, such as Panpan. We've provided a lot of ceramic fiber board for domestic fire doors business. Ceramic fiber board used in fire doors and other ceramic fiber boards are different in production technology. In addition, fire doors ceramic fiber boards are lighter than common ceramic fiber boards.

     Mr. Ha communicated with our engineer for a whole morning, and then made a  conclusion that ceramic fiber board can be applied to fire door. Mr. Ha said,“ Cooperating with such a professional manufacturer assures me a lot. Double Egret is not only a ceramic fiber manufacturer, but a leader of ceramic fiber innovation, developing more applications of ceramic fiber.”
