Project Summary:

The library at Double Bay was designed to have large open spaces with indoor greenery. This caused the potential for rapid fire spread in the case of a fire. Greene Fire were elected to solve this issue utilising our industry leading fire engineered solutions. Project: Double Bay Library, NSW Architect: Andrew Wong/Donal Challoner Fire Engineer:Defire Application: Atrium

Technical Issue

The aesthetic design of each building includes an atrium type void with a large open space staircase connecting floors. This allowed the development of a grander open space area with a modern design. The non-required non-fire isolated stair within the library tenancy may connect the first, second and third floors providing it is protected by a full height vertical concertina curtain at the top of the staircase. This curtain was required to have a minimum FRL of -/120/-. The void in the level 3 floor slab within the library tenancy must be protected by a horizontal fire rated curtain which achieves a minimum FRL of -/120/-.

Our Solution

Our FireMaster range of products was determined to be the ideal solution for this issue. Our FireMaster Concertina was used to protect the inter-tenancy staircase and was designed with a total of 10 sides creating a guide-less circular shape which completely closed the opening. The use of our FireMaster Concertina allowed the designers to make their design a reality by limiting the restrictions that were placed upon them surrounding fire safety and compartmentalization. Our FireMaster horizontal was used to protect the void on level 3. This was the best solution as it does 1 horizontal curtain can be used as opposed to multiple vertical curtains and is often less costly than the FireMaster Concertina.
