FIRE RESISTING DUCTWORK

Fire-resisting ventilation or extraction steel ductwork is designed using proprietary materials and fixing techniques to contain fire and the products of combustion in a manner that does not allow passage to other parts of the building from the compartment of origin for a stipulated time period. Fire-resistant ductwork can also be constructed without a steel lining duct using self-supporting board and casing systems made from calcium silicate and cement based products.

Areas of application include:-
• smoke extract systems
• dual ventilation/smoke systems
• pressurisation systems
• car park extract systems
• kitchen extract systems

Fire-resistant ductwork systems must be fully tested or independently assessed to the requirements of EN 1366-1. This must include the method of support and the type of seal used around the ducts where it penetrates a wall or floor. Ductwork should be tested for both fire outside and fire inside both in horizontal and vertical orientations, unless the end use conditions are to be restricted.
