Lignacite 100 mm 3.6 N Concrete Blocks - Fine-Textured Loadbearing Units
Verified by manufacturer 1 day ago
BSI Kitemark
Certificate type
Part of a range of fine-textured loadbearing units, suitable for facing and general purpose applications.
Application
For walls that are to be directly decorated, Paint Grade blocks should be specified.
For walls built fair, Fair Face blocks should be specified.
Walls of 210-215 mm thickness are recommended to be constructed using two leaves of 100 mm Lignacite blocks laid back-to-back and suitably tied. This construction is known as a collar-jointed wall.
Can be used in the following locations:
- The inner leaves of external cavity walls;
- Internal walls, including fire break walls and separating walls.
If required, the blocks can be drylined or plastered.
Description
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 in fair face and directly decorated walls.
- High levels of air tightness, sound insulation and fire resistance.
- Credits available under BREEAM.
- BSI Kitemarked to BS EN 771-3.
- Can be used to satisfy the requirements of Part L of the Building Regulations.

Recyclability | 100% |
Expected Life | 100 year Guidance for specification option: When properly constructed, the durability of walls built using Lignacite products will match that of walls 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 concrete 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. |
