Planning detail

What to confirm before choosing materials.

01

Start with layout, not board count

A board count without layout details can miss trims, fascia, stairs, direction changes and wastage. Decide whether boards run toward the view, along the longest edge or across a doorway before final quantities are requested.

  • Mark board direction on a sketch or plan.
  • Separate stairs, landings and perimeter zones.
  • Allow for cuts, breaker boards and perimeter finishing.
02

Support, drainage and movement

The supporting frame must be level, stable and arranged so water can drain. For WoodEver 25mm Standard and Bullnose boards, joist centres must stay within 350mm. Allow movement gaps at walls and board ends instead of fixing boards tightly between hard edges.

  • Keep joist centres within 350mm.
  • Maintain drainage at thresholds and edges.
  • Do not close ventilation paths with trims or fascia.
03

Board joins, clips and direct fixings

Both ends of every board join need joist support. Use the compatible clip system for the field boards, and pre-drill any direct screw fixing into a WPC component to reduce local stress around the screw.

  • Support both board ends at every join.
  • Choose the compatible clip system before ordering.
  • Pre-drill direct screw fixings into WPC components.
