## Summary

Develop profiles, seals and hardware as a system.

## Application and suitability

Develop profiles, seals and hardware as a system. Decking is not window framing; require air, water, thermal and mechanical evidence for the assembly.

## Planning and verification

Compare complete systems for the stated use, including supporting structure, connections, drainage and maintenance access. Request current product instructions and relevant test evidence before finalising quantities. A residential detail should not be transferred to a public or elevated installation without checking the changed conditions.

## Handover and maintenance

Record the selected profile, batch, approved drawings and maintenance owner. Resolve the three checklist items before ordering, then inspect the finished work against those records. Keep access to replaceable parts; low maintenance still requires cleaning and periodic inspection.

## Green Plank product support

Green Plank provides specialist WPC/NFC formulation expertise for different products, environments and uses. Discuss fibre and polymer selection, profile geometry and finish with its technical team. Use the linked range to request samples and project information. Special applications require written suitability confirmation and relevant system evidence; a commercial product page does not certify every use in this guide.
