Application

Lignacite ECO 70 blocks are available in a Paint Grade finish. If left Fair, some colour variation will be discernible.

Typical applications include:

  • The inner leaves of external cavity walls;
  • Internal walls, including fire break walls;
  • Separating walls.

Where the appearance of the wall is important, walls of 210-215 mm thickness are recommended to be constructed using two leaves of 100 mm Lignacite ECO 70 blocks laid back-to-back and suitably tied. This construction is known as a collar-jointed wall.

Description

Lignacite ECO 70 concrete blocks are made with at least 70% recycled content. Not only does this conserve the use of primary materials, but it also results in a product with lower embodied carbon compared to most conventional masonry materials.

An independently verified Environmental Product Declaration (EPD) confirms the key environmental data of Lignacite ECO 70, ensuring transparency and sustainability.

Lignacite ECO 70 blocks are medium grey in colour with a close-textured surface. Blocks are manufactured from naturally occurring aggregates and some colour variation between blocks will be discernible. 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’ exclusive mix design (consisting of cement, fine aggregates and recycled graded-wood particles) accounts for their outstanding technical performance.

Features and benefits:

  • Loadbearing.
  • For use internally and externally, above and below ground.
  • High levels of air tightness, sound insulation and fire resistance.
  • BSI Kitemarked to BS EN 771-3.
  • Can be used to satisfy the requirements of Part L of the Building Regulations.
  • Contains a high percentage of recycled materials.
