Application

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:

Inner and outer leaves of external cavity walls
Internal walls, including fire breaks
Below ground (7.3 N/mm² strength blocks should be used for walls exposed to the external ground).

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 Lignacite GP and Ligancrete ranges.

Description

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:

Provides a high level of thermal insulation, reducing the amount of additional insulation required after installation.
Lightweight, easy to handle, and quick to lay.
Loadbearing.
Provides a high level of fire protection (Class A1).
For use internally and externally, above and below ground.
Provides a strong background for direct application of plasters and renders (no bonding agents required).
Fixings will be held securely by the block (and can be nailed in directly).
Certification to BES 6001 V4.0 will allow credits to be gained under environmental assessment schemes such as BREEAM.
BSI Kitemarked to BS EN 771-3.

Recyclability	100%
Recycled content As defined in clause 7.8 of BS EN ISO 14021	0 %
Expected Life	100 year Guidance for specification option: When properly constructed, the durability of walls built using Fibo 850 products will match that of traditional masonry and will fulfil their intended function for the life of the building in which they have been installed (typically 100 years). The blocks themselves will require no maintenance. Maintenance for walls will normally include the replacement of sealant in movement joints and at junctions / openings. Repointing for walls that are exposed to the elements may be necessary towards the end of their service life.
