Fibo 850 super lightweight concrete blocks are suitable for general-purpose walling applications. They provide a good base for plasters, renders and fixings, and the 100mm option combines easy handling with great thermal efficiency values.
Manufactured to BS EN 771-3, they consist of expanded clay aggregates and a mixture of other naturally occurring raw materials and cement. The clay aggregate is produced from carefully selected clays, which are bloated through heat expansion to create a low density, porous aggregate with numerous cavities. This makes Fibo 850 incredibly light and thermally efficient.
