01Evidence and project suitability
The required evidence depends on the building and approval pathway. Request current WoodEver information for the exact WPC cladding and equivalent supplier documents for the selected timber species, grade, treatment and coating system.
- Create one evidence checklist for both options.
- Reject unmatched or outdated documents.
- Record who accepts each project requirement.
02Appearance and sample review
Manufactured castellated WPC and natural timber present different patterns and variation. Compare physical samples with adjoining materials and decide how corners, cut edges, boards and finish changes will appear over the complete elevation.
- Review samples in the project light.
- Agree acceptable variation before ordering.
- Detail visible ends, joins and transitions.
03Complete wall and care scope
Compare more than face material price. Include supports, cavity components, trims, fixings, coatings where applicable, installation labour, access and the care steps specified by each current supplier document.
- Request like-for-like wall schedules.
- Separate initial and ongoing work.
- Do not assign maintenance intervals without product-specific evidence.
