Tile Fixing

Sandtoft roof tiles must be laid and fixed to comply with BS 5534: the British Standard Code of practice for slating and tiling, and BS 8000: Part 6: the British Standard Code of practice for workmanship on building sites.
To ensure compliance with these Standards we strongly recommend that either the recommendations given in the Sandtoft Zonal Method User’s Guide and Zonal tables must be followed where available or a calculated fixing specification must be obtained using Sandtoft’s Fixing SPEC service.
 
For further information go to Fixing SPEC or contact Sandtoft Technical Services on 0844 9395 999.
