Features & benefits:
- Because the strips are split along the grain, the surface texture is rougher and more fibrous (unlike smooth sawn laths), which gives better key (mechanical bond) for plaster—especially lime-plaster systems. For instance, The purpose of the riven lath is to provide extra grab for the fibrous lime plaster. The splitting follows the grain and leaves an uneven ‘reeded’ surface. This means that the plaster will stick and grip.
- Chestnut has naturally good durability (often contains tannins) and is suitable for splitting. Sweet Chestnut is ideal for traditional riving, strong and durable like oak although less dense, this makes chestnut much easier to soak and well suited for traditional laths.
- It is typically sourced from sustainably managed coppice woodlands in the UK (for domestic UK supply).
Uses and Applications:
- Walls & ceilings where traditional lath-and-plaster construction is used (rather than modern plasterboard). The rough texture of riven chestnut laths makes them ideal for lime plaster and overhead/ceiling work.
- Conservation/restoration of historic buildings, where matching original materials and methods is required.
