Scottish school sets tough test for slate refurbishment

Lochwinnoch Primary School in Scotland has provided a showcase for Cambrian Slate from Redland, showing how an early 1900s traditional building can still retain its original appearance using a modern slate substitute, along with traditional slate detailing. The roof of the 111-year-old school was originally slated using Scotch slate that was at the end of its lifespan so rain penetration was causing a major issue.

Redland carried out a full Redland SpecMaster roof specification together with James Grant, examining every aspect of the roof in detail. These included raking valley details, sprocketed eaves, changes of pitch on the roof slope, detailing of top edge and side abutments, flat to pitch lead, ventilation at eaves and ridge, and underlay details.

All work was carried out in compliance with BS 5534: 2014 Code of Practice for Slating and Tiling and BS 5250 Code of Practice for the Control of Condensation in Buildings, ensuring that high and low-level ventilation was provided along with two mechanical fixings for each tile.
