Profiled, not yet in the designer

The designer can’t fit this range until the sources publish no board sizes published. You can still design with a similar board.

Gap between boards
3 mmSources disagree. Maker’s install guide says 5 (Plastic board clips (installation guide).); Maker’s datasheet says 5.5 (Moulded ABS fastener (ELITE specification sheet).). The published value comes from the higher-ranked source; safety facts take the conservative one.

End gap rule
Total expansion of a 5.4 m board: 1.08 mm for a 5 °C change; 2.16 mm for a 10 °C change; 3.24 mm for a 15 °C change; 4.32 mm for a 20 °C change; 5.4 mm for a 25 °C change; 6.48 mm for a 30 °C change; 7.56 mm for a 35 °C change; 8.64 mm for a 40 °C change · Expansion coefficient: 44.2e-6 (ELITE specification) · Worked example: 5.4 m board in full sun, 25 C laid to 55 C: about 6 mm total, so 3 mm gap each end to framing/breaker board
How this was read

Installation guide "Thermal expansion" sheet (total board variance for a given temperature change; 0.2 mm per metre per 5 C). Surface temperature in full sun is quoted as up to about 60 C. The guide says a blanket 3 mm gap is usually too large for butt joins in shade and gives worked examples; no fixed gap table.

All 4 sources behind this page
  1. ULTIMATE composite decking page (ASA laminate, P3, 450 mm centres, four colours) · Sun Decking · opened
  2. Sun Decking home page (three composite lines, 15-year warranty claim, east-coast supply) · Sun Decking · opened
  3. Sun Decking installation guide page (image sheets: hidden clips, thermal expansion with examples, butt joints, joist layout, panel and framing options) · Sun Decking · opened
  4. Sun Decking ELITE composite decking specifications (PDF: composition, weight, density, slip, expansion, joist centres) · Sun Decking · opened

Facts are taken from the highest-ranked source (certificates and test reports, then install guides and datasheets, then warranties, then web pages); when sources disagree the specification says so, and safety facts take the conservative value. Every plan the designer draws from these figures is a concept plan, not for construction: the span tables behind its framing have been checked by a structural engineer, but a builder, building surveyor or certifier must check the plan before you build.
