So, the fire resisting duct demands to keep up i.e., not compromise the fire resistance from the wall or floor by which it penetrates. The performance of the fire resisting duct which penetrates a fire resisting/separating aspect involves very careful consideration by specifiers and controlling authorities. The regular periods of security and integrity need to in all conditions be not less than equal to those essential for your penetrated ingredient of building.
Analyzed in horizontal along with vertical orientation independently below cellulosic (conventional time Vs. temperature curve) fire situations and successfully reached more than one hundred twenty minutes of fire resistance for integrity and steadiness of
A world product evaluation and certification of your fire resistance performance for air flow and smoke extraction ducts is remaining accomplished by Applus+ Laboratories
It really is most crucial to pick the most fitted fire resisting ductwork method for its supposed software area to make certain that the ductwork fire effectiveness satisfies the requirements of your relevant application.
