Suspended plasterboard ceiling Double Suspended Plaster Board This is the section which is the roof north of function room. ď Ž Waterproofing: sealant and sarking ď Ž Flashing: 1) Continuous piece of sheet metal which is installed to prevent the passage of water into the structure (Ching 2011 7.18) 2) Operates on the principle that: for water to penetrate a joint it must work itself upward against a force of gravity (Ching 2011 7.18)

3) Building process This building is building. The main structure is the steel universal beam
4) Pros and Cons a) Pros ‘UB’ beam is lightweight and less prone to warping and cheap Suspended plasterboard ceiling (Armstrong.com 2013) : 1) Sound proofing 2) Moisture and sag resistant 3) Fire safety 4) Easy access to home systems 5) Eco-friendly
Plaster systems offer a number of practical and aesthetic designs. Fiber-cement Sheeting (Doityourself.com 2013): 1) Durable 2) Fire-resistant 3) Doesn’t rot 4) long-lasting building materials 5) cheapness 6) easy availability Timber stud & Timber roof beam: 1) Quick worked due to non dependence on weather 2) Excellent thermal qualities and insulation Metal Flashing: 1) High durability
2) With sealants that are more flexibility b) Cons ‘UB’ beam is rapid loss of strength in a fire if unprotected Fiber cement roofing 1) Not re-usable 2) Non-recyclable 3) Very poor insulator 4) Low thermal mass Metal Flashing: 1) Cost higher 2) Easier corrosion and rust
5) Sustainability and environmental a) Carbon Footprint Synthetic Rubbers: Silicone Sealant Plastics: Sarking b) Embodied Energy The plasterboard has high embodied energy c) Recyclability Fiber cement roofing is non-recyclability Steel is 100% recycle
6) Economic implications of decisions It is a cheap site a) Fiber-cement Sheeting
b) Steel universal beam c) Suspended plasterboard ceiling: much cheaper than renovation
7) Things go wrong Remove openings 1) Sealants may deteriorate over time 2) Flashing—water has to work against gravity
Glossary: Transom: (Dictionary of Construction.com 2013) It is a horizontal glazed or solid panel above a door or window. It usually hinged and used for ventilation in the building.
