Cellecta HEXATHERM XCPL 166mm Thermal Laminate Board

The 166mm HEXATHERM XCPL is a premium composite insulation solution engineered to deliver high levels of thermal efficiency alongside a durable and visually refined internal finish. Developed using advanced extruded polystyrene (XPS Insulation) technology, this board integrates a high-performance insulation core with a tough Class O rated impact-resistant facing layer, creating a robust thermal lining system suitable for demanding exposed environments.

Unlike standard insulation materials, HEXATHERM XCPL is specifically designed for applications where insulation performance alone is not enough. It provides a combined solution that enhances energy efficiency while also delivering a clean, professional surface finish in areas that remain visible after installation.

Its reinforced facing layer offers excellent resistance to impact, abrasion and general wear, making it particularly effective in high-traffic or exposed zones such as underground car parks, concrete soffits and commercial ceiling voids. This dual-performance design ensures long-term durability while maintaining aesthetic quality over time.
