Composite cladding, fencing and other applications

Why each composite application needs its own specification.

At a glance

A material suitable for one application is not automatically suitable for another. Cladding, fences and moulded parts need separate product and assembly reviews. Define the use, exposure and supports before transferring performance claims.

Key points

  • Project-specific façade requirements
  • Exposure and support design
  • Loads, contact surfaces and cleaning

One material family, different jobs #

A material suitable for a deck is not automatically suitable as façade cladding, fencing or furniture. Geometry, fixings and exposure change with the application. Start a fresh product review each time the use changes.

Cladding: review the assembly #

Ask for evidence for the proposed wall assembly, including its fixings and substructure. Fire requirements are project- and jurisdiction-specific; have the project team verify the applicable requirements. Do not infer compliance from a generic material description.

Fencing: consider the supports #

Check the panel, rails, posts and connections as a system. Ask how the proposed design addresses wind exposure and movement. Make sure the quoted configuration is the one covered by the supplier’s design information.

Furniture and moulded parts #

Natural fibres also appear in moulded polymer components. For seating, screens or interior parts, write an application-specific checklist covering loads, cleaning, exposure and replaceable parts. Require evidence for that component rather than relying on a result from another product family.

Common questions

Is WPC cladding automatically fire compliant?

No. A material name is not compliance evidence. The applicable requirements and assembly need a project-specific review.

Can decking profiles be used as fencing?

Only when the proposed use and connections are supported by suitable product and design information.
