Thermacell is Australia's #1 mainstream ICF fire-retardant Polystyrene Formwork (ICF) used for primarily casting concrete wall and other structures while delivering advanced insulation, thermal and acoustic properties in the one process.

The blocks are dry-stacked without mortar, and have keyways top and bottom which allow them to push together like LEGO blocks.

The blocks are hollow and are filled with concrete.

The strength, thermal and acoustic properties of a Thermacell building far exceed any other type of building system.

Thermacell homes are virtually maintenance-free.
