Product specification is subject to change and will be updated accordingly.
For projects where the rafters are below the minumum recommended roof pitch,
please contact our Technical Services for advice
** Clay tiles are subject to small variations in size because of drying and firing
shrinkage in the manufacturing process. Before deciding on the batten gauge and
linear coverage, the roof tiler should inspect each batch of tiles to ensure that
the correct minimum headlap and sidelap are achieved. For further guidance, download
the
Rivius Installation Guide.
Note: unless otherwise stated, data is based on the tiles laid at minimum headlap.
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.
