The ARGISOL +15 line includes an innovative construction system based on expanded polystyrene (EPS) formwork blocks with recycled material content, certified under the ReMade label. The system is designed for the construction of insulating walls in the building sector, integrating structural function and thermal insulation in a single construction solution. The different dimensional configurations allow the system to be adapted to design requirements in terms of wall thickness and thermo-mechanical performance, improving the energy efficiency of the building envelope and reducing the environmental impact of the materials used.
