Suspended timber joist floor insulated by a rigid PIR insulation board installed between the floor joints below structural flooring.

Suspended steel frame floor insulated by a rigid PIR insulation board installed between the floor joints below structural flooring.

2 layers of a highly moisture resistant, high compressive strength DCT XPS insulation are laid in a staggered pattern above a concrete floor slab. For moisture management, a ProctorGeo vapour barrier is placed both over and under the insulation prior to pouring the reinforced cold store floor slab.

Timber is commonly used for residential floors using beams and joists and can be delivered as floor cassettes and attached to stumps on site.

Made from concrete with steel reinforcing, these floor slab are suspended above-ground.

Steel can be used to provide a sturdy beam and joist subfloor frame, and is often supplied and installed in modular form.
