Fire performance

The insulating properties of timber can provide built-in fire resistance. Large timber members burn slowly and form char on the surface.

Fire development in buildings

Even though wood does burn, the contribution from the timber building materials to the fire load is usually small compared with the contribution of the building contents which constitute the main source of fuel.

However, large areas of wood-based surface linings in buildings can contribute to faster fire spread and this needs to be taken into account as other building design features may be required to mitigate the effects.

Design of buildings for fire safety is a complex topic requiring integration of a large number of sometimes conflicting requirements.

Key Features

Key Features:

 

  • Timbercrete blocks are handmade in Rotorua and are constructed with over 50% of timber shavings, sourced from local mills and combined with aggregate and concrete.
  • The thermal factor of this timber component is high and warm to the touch inside the home and has an extremely high acoustic performance.
  • Radiata pine was used extensively for all beams, rafters, balustrades, shelving and the main elements were pre-stained prior to installation.
  • Shadowclad T&G sheets were used for the sarked ceilings and panels to the walls.
  • The Cedar garage doors
  • Eucalyptus Main Entry door
  • Shadowclad to disguise the external beams
