How to choose the board of ventilation duct

Ventilation duct is an essential material for engineering decoration, often used in exhibition halls, stadiums, waiting rooms and other large space buildings, as well as the ventilation system, exhaust system, smoke exhaust system in the workshop, since the air duct is the air duct plate, then how to choose the plate of the ventilation duct?

In fact, the board used in the ventilation system should be A board with high fire protection requirements, such as Huangrui A-grade fire proof board, whose fire resistance grade is A-grade, which belongs to almost non-burning materials in the classification of combustion performance of building materials.

The fire resistance limit of Class A fire-proof board can reach more than 3 hours.

Class A fire-retardant board as a ventilation duct has several advantages, namely E1 formaldehyde, waterproof and moisture-proof (extremely important in the ventilation system), light weight, shock-proof (wind and noise resistance), excellent strength (5mm thick plate, folding strength 65 MPa), insect and mildew proof, heat insulation, non-toxic and tasteless, no radioactive substances (to avoid pollution, environmental protection).

Therefore, Class A fire-retardant panel has become the first choice for ventilation duct panels.
