Thermostone Plus - Reliable – Insulating – Quick Assembly

Thermostone Plus is a formwork which is made from expanded polystyrene, allowing the basic pool to be constructed from lightweight blocks, strengthened with steel rebar & then the internal cavities are filled with concrete.

The insulation value of Thermostone Plus block system is much higher than standard construction methods, which means lower heating costs & huge savings on energy.

Unlike other block systems Thermostone Plus Blocks allow the concrete fill to be pumped in up to a depth of 1.75m.

Thermostone Plus PS80/40 have similar characteristics to the original PS40 blocks, but the PS80/40 have an additional layer of PS80 on the pool side, resulting in an exceptionally hard pool wall surface that resists dings, dents and deformities
