Microporous board for elevator door insulation

Nano Insulation Board is a High-purity silicate board for high temperature industry from 800℃ to 1100℃ wrapped in glass fibre cloth and can be used as Elevator door fireproof material. Fire protection board for elevator door is constructed by sandwiching the board between two door panels backing up to realize the function of heat insulation. The most commonly used thickness on fire-proof passive doors is from 12mm to 18mm, and our boards can remain non-deformed after 120 minutes of calcination. At the same time, due to the microporous structure of the fire protection board for elevator door, it has a sound-absorbing effect at the same time. With the standard of elevator industry become more and more strict, it is a tendency to apply Microporous insulated board into elevator door for the purpose of fire prohibition.
