Thermal rating

Under normal ambient temperatures, the “R” values for various thicknesses of plasterboard
are as follows:


10mm: 0.060 m2K/W
13mm: 0.079 m2K/W
16mm:

0.098 m2K/W


For foil backed plasterboard with foil facing an empty wall cavity add the following values
to the above ratings:

20mm min. cavity:  0.58 m2K/W 
>20mm cavity 0.61 m2K/W

 

Dimensional Stability

Under normal temperature and humidity conditions, plasterboard dimensional properties
are as follows:

  • Thermal Coefficients of Linear Expansion = 16.2x10-6mm/(mm°C) –at temperature
    range 4°C to 38°C
  • Hygrometric Coefficient of Expasnsion = 7.2x10-6mm/mm/%RH – at 5% to 90% RH

Safety and First Aid

Although there are no health hazards known in the normal use and application of plasterboard, the following precautions should be observed:

  • Avoid creating dust when handling plasterboard or mixing plaster products.

  • Reduced sanding by passing a wet sponge over the edge of the finished joints after trowelling.

  • If dry sanding is necessary and dust is created, provide adequate ventilation, wear eye protection and a disposable respiratory mask conforming to Australian/New Zealand Standard AS/NZS 1716:1994 Respiratory Protective Devices

  • Keep all construction materials and tools out of reach of children

  • If plaster compound or dust comes into contact with eyes
    - wash eyes thoroughly with water

  • If plaster compound or dust comes into contact with skin
    - wash skin thoroughly with soap and water

  • If plaster dust is inhaled
    - move to a fresh air environment

  • If plastering compound or dust is ingested
    - drink plenty of water
