LIGNACITE LTD: Fibo 850 100 mm 3.6 N Concrete Block Range
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 will allow credits to be gained under environment assessment schemes such as BREEAM.CE marked to BS EN 771-3.For 7.3 N/mm² compressive strength, see Fibo 950 blocks; consult manufacturer for details.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.

LIGNACITE LTD: Lignacite 100 mm 7.3 N Concrete Blocks - Fine-Textured Loadbearing Units
Lignacite concrete blocks are fine textured and available with a paint grade or fair face finish. Manufactured to BS EN 771-3, Lignacite blocks are robust and durable with a technical performance that makes them well-suited to most applications.The blocks’ unique mix design (consisting of cement, fine aggregates and recycled graded-wood particles) accounts for their outstanding technical performance.The 140 mm width version (known as Lignacite SP; specified separately) has a specially formulated mix that optimises the block density to produce a solid block with a unit weight of less than 20 kg. There is a slight colour difference between Lignacite SP and 100 mm Lignacite blocks.Features and benefits:Loadbearing.For use internally and externally, above and below ground.High levels of air tightness, sound insulation and fire resistance.Credits available under BREEAM and Code for Sustainable Homes.CE marked to BS EN 771-3.Can be used to satisfy the requirements of Part L of the Building Regulations.MortarGenerally, the mortar type for work above ground level should be designation (iii) / Compressive Class M4. Stronger mixes may be required if blocks are used below ground.MovementVertical movement joints should be considered in accordance with masonry design codes and the recommendations of Published Document PD 6697, at 6.0-8.0 metre spacings. In areas of raised stress, such as above and below openings in external walls, the blockwork may need to be reinforced to restrain movement.DesignThe design of walls using Lignacite blocks should be in accordance with relevant design standards, including BS 8103: Part 2, BS EN 1996-1-1 and the requirements of the Building Regulations.

LIGNACITE LTD: Lignacrete 100 mm Solid 7.3 N Concrete Blocks - High Density Robust Loadbearing Units
Lignacrete dense concrete blocks are robust and durable with a technical performance that will fulfil most applications. They are manufactured to BS EN 771-3 and are available in standard and paint grade (close textured for direct painting). High strength blocks up to 30N/mm² are available for demanding, loadbearing designs.Features and benefits:Loadbearing and robust.High strength.For use internally and externally, above and below ground.High levels of air tightness, sound insulation and fire resistance.Suitable for a wide range of applications, including separating and partition walls.Credits available under BREEAM and Code for Sustainable Homes.CE marked to BS EN 771-3.Can be used to satisfy the requirements of Part L of the Building Regulations.Generally, the mortar type for work above ground level should be designation (iii) / Compressive Class M4. However, where it is needed to maximise the loadbearing capacity of the wall, designation (ii) / Compressive Class M6 mixes should be specified. Stronger mixes may also be required for work below ground.Vertical movement joints should be considered in accordance with masonry design codes and the recommendations of Published Document PD 6697, at 6.0-8.0 metre spacings. In areas of raised stress, such as above and below openings in external walls, the blockwork may need to be reinforced to restrain movement.The design of walls using Lignacrete blocks should be in accordance with relevant design standards, including BS 8103: Part 2 and BS EN 1996-1-1 and the requirements of the Building Regulations.
