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.
