Metal Fire Rated Air Supply Valve

MVHR fire solutions are used to support ventilation ductwork installations where fire protection measures are required. Products may include fire collars, fire sleeves, fire wraps and fire-rated air valves depending on the project.

Fire collars, sleeves and wraps are different fire protection products used in ventilation and service penetrations. The correct option depends on the duct material, duct size, wall or floor construction and installation requirements.

Fire dampers may be required where ventilation ductwork penetrates certain fire-resisting walls or floors. The requirement should be confirmed from the project's fire strategy and applicable regulations.

Requirements may include fire dampers, fire-rated ductwork, collars or other penetration-sealing products depending on the building and duct routes. The project fire specification should always be followed.

Fire dampers are commonly used where ductwork passes through fire compartments, but the exact requirements depend on the building design, fire strategy and applicable regulations.
