Fibo 850 lightweight concrete blocks are suitable for general-purpose walling applications.
Fibo 850 is suitable for housing and building extension projects. They can also be used to construct walls in buildings where blockwork with a low self-weight has been specified (e.g., partition walls on floor slabs).
Typical locations include:
Fibo 850 blocks have an open textured surface, which is ideal for applying plaster and render. Consult manufacturer for further finish recommendations.
For use in separating walls meeting the requirements of Part E of the Building Regulations, we recommend the use of products from the Ash GP and Ligancrete ranges.
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 100 mm option combines easy handling with great thermal efficiency values.
They are also Category 1 masonry units manufactured under a BSI-certified Quality Management System, which is BS EN 9001 compliant.
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.
Features and benefits:
The mortar type for work above ground level should be designation (iii) / Compressive Class M4. Stronger mixes may be used only with the permission of the designer. Stronger mixes may also be required for work below ground in accordance with PD 6697. Consult manufacturer for details.
Movement joints should be considered in accordance with PD 6697 at approximately 6 m spacings. In areas of concentrated stress, such as those above and below openings, consideration should be given to the use of bed joint masonry reinforcement.
The design of walls should be in accordance with relevant design standards including BS 8103-2, BS EN 1996-1-1 and the requirements of the Building Regulations.
