Our Thermostones are the ideal building blocks for fast, efficient and high-quality pool construction. Thanks to optimizations in both the mold and the material, the PS80 variant meets our high quality standards 100%. The pool side of the PS80/40 has been given a blue color. This provides additional recognition and easy differentiation between the PS40 and PS80 variants.
And the best news? Despite these improvements, the price remains unchanged!
