Concrete Floor Construction

New Homes

Foamcrete can be placed as an insulating screed beneath new concrete floor construction. Thermal insulating concrete can be placed in various configurations either as edge insulation to the floor or as a complete insulating screed such as would be required if in–floor heating was being installed.

Advantages of using Foamcrete as an insulating screed:

  • It is up to 5 times more effective than conventional concrete at reducing heat loss (without underfloor insulation up to 20% of heat loss is through the floor)
  • Improved quality control
    • Eliminates problems caused by damage to the damp proof coarse (polythene) prior to and during concrete floor placement
    • Eliminates difficulties associated with using polystyrene as underfloor insulation since there are no gaps, joins or movement.
  • Gives a firm even base for the structural floor.
  • Easily placed (supplied and placed by Canterbury Foam Concrete qualified staff)

Note: Recommended density for sub floor insulation is between 600 - 900kg per cubic metre

Here’s a novel idea! Help the environment, use the air storage capacity of recycled bottles surrounded with Foamcrete to produce thermal insulating screed beneath your new concrete floor.

In parts of the world, lightweight concrete blocks or bricks are a common building material for houses because of the insulating properties of the foam concrete. In New Zealand Canterbury Foam Concrete has completed construction of a house in Nelson made from Foamcrete blocks.
