Building Element Assessment Laboratory (BEAL) has been looking at the need to improve the insulation properties of slab on ground concrete foundations to meet the expected new thermal performance standards for dwellings.
A research project was started last year which looked at the incorporation of insulation into a permanent formwork system.
The system is being developed in conjunction with experienced tradesmen to ensure its ease of use, as well as meeting Building Code requirements.
Barnes Plastics’ Voidform waffle raft slab system consists of an on-ground reinforced concrete slab supported on a grid of reinforced concrete ribs on a level building surface.
It is a system that provides a high level of built-in insulation.
