Installation Instructions

Please refer to the STRUCTAflor Installation and Design Manual

AS1860.2 Particleboard Flooring Part 2: Installation sets out the minimum performance requirements for the installation of particleboard flooring which are acceptable to building authorities in Australia.

Thermal Insulation

The thermal conductivity of STRUCTAflor is 0.12W/mK. Thermal resistance (R-values) calculated in accordance with the relevant provisions of Australian Standard AS/NZS4589.1 for the nominated thicknesses are:

  • YELLOWtongue 19mm R0.16
  • REDtongue 22mm R0.18
  • BLUEtongue 25mm R0.21

Exposure, Storage & Handling

STRUCTAflor may be exposed to the weather for up to 5 months, however it is always advisable to enclose the building as soon as possible after laying the floor. Any ponded water should be removed as soon as practicable. This can be achieved by drilling holes of 8mm maximum diameter at not less than 1 metre spacing through the floor where ponding occurs and sweeping water away.

When storing outside ensure packs are kept clear of the ground. Cover with waterproof sheeting laid on timber battens so that air circulates freely between the waterproof cover and the product. Handle and stack with care to avoid damage.


Gloves, dust masks and glasses should be worn at all times when working with timber. Please refer to Material Safety Data Sheet (MSDS) for full details.

Waste Disposal

Off-cuts can be disposed of as normal landfill waste. Do not burn treated timbers. Please refer to above Material Safety Data Sheet (MSDS) for full details below.
