The difference between the glass fire door and the wooden and steel fire door is that it is embedded with a large area of fire resistant glass. After high temperature, the transparent jelly like fire resistant adhesive layer in the middle of the glass will quickly harden to form an opaque fire insulation panel. The high-quality fireproof glass door can still last for more than 90 minutes under the impact of the flame up to 1000 ℃, which also wins precious time for people’s escape and disaster relief.
