This draft is for visual review. Material suitability must be confirmed from approved product documentation and project requirements.
Start with the complete system
ACP, HPL and WPC describe different material families. Their fixing, substructure, joints and permitted applications depend on the specific product and system.
Compare the project conditions
Review the substrate, orientation, weather exposure, desired finish, maintenance access and the interface with windows, parapets and adjacent materials. Check current manufacturer documentation and applicable project requirements.
Do not compare material names alone. Compare a defined product and its installation details for the building in question.
