Background The Blacktown & Mount Druitt Hospitals Expansion Project includes a state-of-the-art mental health unit, thoughtfully designed with input from staff, consumers, and community members. The facility prioritizes comfort for those seeking mental health support and fosters a safe environment conducive to cultural, emotional, psychological, and physical well-being.
Requirement The client required a vapor-permeable, water barrier, pliable building membrane that meets non-combustible standards for use in external walls and facade systems. This membrane needed to comply with the stringent performance requirements of a hospital building in ABCB Climate Zone 6 and meet facade warranty standards. The project involved a building classified as 9a and constructed as Type A (non-combustible), using predominantly lightweight cladding and steel-frame construction. The design aimed to enhance occupant health and safety, ensuring the strength and durability of the construction. Internal rooms required a thermal break, necessitating a non-combustible, vapor-permeable, water, and air barrier.
Approach The project team carefully selected compatible materials to meet and exceed the design criteria, with special attention to technical installation methods and thermal breaks.
Benefits Ametalin CeaseFire® allowed the team to exceed the Deemed-to-Satisfy requirements for the fire resistance of external facades. CeaseFire® is inert and nearly non-combustible, surpassing the requirements for DtS Non-combustible Type A constructions. It also offers Class 4 Vapor Permeance (NCC2022 Condensation Management for ABCB Climate Zones 4 to 8), functions as an air, smoke, and water barrier, and provides over 180 days of UV resistance. With more than double the strength of Extra Heavy Duty membranes, Ametalin CeaseFire® delivers superior performance and durability, enhancing the safety, health, and amenity of the building and its occupants.
Due to the nature of constructing a mental health facility, metal sheets were specified behind all internal wall linings. These sheets needed to be thermally broken, achieved with Ametalin Non-Combustible ThermalBreak Strips. Non-combustible Insulation Flashing tape was used to tape and seal joints around pipes and penetrations, and to prevent water ingress along all 150 mm horizontal overlaps.
Results The resulting construction met and exceeded all management and client expectations, surpassing the minimum requirements for vapor control, weather barrier, and air, water, and smoke barriers for DtS non-combustible design and construction suitable for ABCB Climate Zone 6. The specification, detailing, and installation method of Ametalin CeaseFire® achieved a compliant, robust, and seamless weather barrier layer. Combined with thermal breaks, this enhanced fire mitigation, weather tightness, condensation control, and energy performance of the Blacktown & Mount Druitt Hospitals Expansion Project's non-combustible building envelope.
