C-MAX FPG2 Floor Panel 200mm

CEMEX Holdings Limited: C-Max EPS FPG2 Floor Panel 200mm thick

The C-MAX FPG2 Floor Panel 200mm is a prefabricated expanded polystyrene (EPS) panel designed for floor and roof slab construction where greater structural depth is required for heavier loads or longer spans. Part of the M2 Emmedue Advanced Building System manufactured locally in Kenya by CEMEX Holdings Limited, the panel features a 200mm thickness with 600mm centre-to-centre rib spacing, providing increased structural capacity over the 150mm variant while maintaining the same rapid assembly and lightweight handling advantages. The panel consists of a shaped EPS core enclosed in dual layers of galvanised steel wire mesh, with reinforced concrete joists cast on site to form a composite slab. This construction method achieves approximately 60% less CO2 during construction compared to conventional framed reinforced concrete, while the deeper EPS core delivers enhanced thermal and acoustic insulation performance.

Sustainability Features

• Achieves approximately 60% reduction in CO2 production during construction compared to conventional reinforced concrete framing
• Deeper 200mm EPS core provides superior thermal insulation compared to the 150mm variant, further reducing operational energy demand for heating and cooling
• Lightweight prefabricated system minimises material consumption and on-site construction waste
• Greater structural depth allows longer spans without additional support beams, reducing overall concrete and steel quantities in the building frame
• Locally manufactured in Ruiru, Kenya, reducing transportation emissions and supporting the local construction supply chain
• Galvanised steel mesh and EPS components are recyclable at end of life
• Panel-to-panel connection system creates monolithic structural behaviour, extending building lifespan and reducing long-term maintenance
