Exterior WPC Cladding Installation Guide

This guide is a project-planning resource for exterior WPC cladding. Final installation requirements must follow the current instructions for the exact selected profile and the project's wall assembly.

Coordinate the wall assembly first

Exterior WPC cladding is the decorative finish layer and should not replace the wall assembly's primary water-resistive barrier, flashing, drainage plane, or code-required weather protection.

Installation items to confirm

Exact panel/profile and orientation
Substrate or furring arrangement
Required cavity, drainage, and ventilation conditions
Fastener or clip type and spacing
Movement and expansion requirements
Bottom, top, corner, and edge terminations
Openings, penetrations, and mixed-material transitions
Clearances from grade, paving, roofing, or adjacent materials

Panel orientation and layout

Horizontal and vertical layouts can create different water-shedding, joint, furring, and trim conditions. Confirm the selected orientation before finalizing framing or furring.

Allow for movement

Composite profiles can move with temperature and environmental exposure. Use the current profile-specific requirements for end gaps, joints, fastener placement, and terminations rather than copying spacing from another product.

Before installation begins

Verify that the delivered profile, finish, trims, clips, and quantities match the approved project layout. Confirm current instructions before cutting or fastening material.
