Grovebury

A double pantile shape is quicker and easier to lay than a single pantile design. However, Grovebury concrete interlocking tiles still retains the traditional, gentle flowing lines of a classic pantile to blend easily and harmoniously into any environment.

A low pitch and a wide variety of colours in through coloured, granular or acrylic finishes makes Grovebury a popular choice for both new build and renovation.

Fixing

Specification

FixMaster is a guaranteed tile and batten fixing specification service tailored to individual roof designs. It's Redland's high technology solution to incorrect fixing providing the most cost-effective specification to comply with British Standards.

As no two roofs are the same, FixMaster takes into account all variable factors including roof geometry, location and products used. A full assessment is made of any nearby tall structures, natural topographical features or, in the case of airports in the locality, pressures generated by aircraft trailing wake vortices.

Methods to obtain a FixMaster are:

  • Visit the FixMaster section of this website to submit the online data sheet
  • e-mail Technical Solutions to order a data sheet
  • telephone Customer Services on 03705 601000 to request one of Redland's Account Managers to visit you

Laying

  • Tiles must be laid in a straight bond pattern
  • Tiles must be hung on their nibs
  • It is always advised that tiles are laid at mid shunt, although the precise roof details may require tiles to be laid more open or closed
  • When laid at mid shunt, tiles will have +/- 1.5 mm of shunt to provide laying flexibility
  • Eaves Comb must be used at all eaves situations.
  • Dentil slips must be used for mortar bedded ridges and hips
  • Individual tiles can be nailed, clipped or nailed & clipped
  • Always refer to FixMaster for a BS 5534-compliant fixing specification
  • When clipping verges, both left-hand and right-hand perimeter tiles must be clipped
