| Waterproofing | Confirm the panel’s core and surface resist water, and check how the edges, joints, corners, and penetrations are intended to be sealed. A water-resistant panel does not make an entire wall assembly waterproof. | Product technical data and written installation instructions; any water-immersion or water-absorption results should identify the test method, sample, and test conditions. | For wet areas, use a system specifically approved for that exposure. Follow the specified sealant, trim, substrate, and joint details, and do not rely on panel faces alone to prevent water ingress. |
| Fire Resistance | Distinguish surface flame-spread or reaction-to-fire classification from the fire-resistance rating of a complete wall assembly. These are different properties. | Ask for a current test report or classification for the exact panel construction. Examples include ASTM E84 or EN 13501-1; check the tested thickness, mounting method, substrate, and classification. | Match the documented result to local building-code requirements and the intended installation. Do not treat “fire resistant” or a surface classification as proof that a wall assembly has a rated fire-resistance duration. |
| Indoor-Air Safety | Check emissions of volatile organic compounds (VOCs), especially for enclosed or frequently occupied spaces. Consider adhesives and sealants as part of the installed system. | Look for a valid emissions test or certification applicable to the product and its intended use, such as testing under the California Department of Public Health Standard Method or a flooring-specific emissions program where applicable. | Review the certificate’s scope and validity rather than relying on terms such as “non-toxic” or “zero VOC” without supporting documentation. Provide ventilation during and after installation as directed. |
| Material Safety | Check the product’s declared composition and whether applicable chemical restrictions and market-specific requirements are addressed. | Request a safety data sheet where applicable, product declarations, and compliance documentation relevant to the destination market. A safety data sheet may not disclose every ingredient in a finished article. | Use documentation tied to the specific product formulation. Confirm that cutting, drilling, and disposal instructions address dust control and other installation precautions. |
| Wear and Scratch Resistance | Review the surface finish and protective layer, while recognizing that layer thickness alone does not establish scratch or wear performance. | Ask for test results using a named method, including the tested surface, conditioning, and acceptance criteria. Request representative samples for visual and handling checks. | Choose a finish suited to expected contact and cleaning. Use non-abrasive cleaners unless the manufacturer’s instructions confirm otherwise, and protect panels from impact during transport and installation. |
| Impact and Dent Resistance | Consider the panel’s construction, thickness, support spacing, edge details, and likely impact exposure. Performance depends on the complete installed arrangement. | Request impact-test data for the specified panel and installation conditions, if available. Confirm substrate flatness, fixing method, and maximum support spacing in the installation guide. | For corridors or other high-traffic locations, select a product with relevant documented impact performance and follow the specified fixing layout. Avoid assuming that a thicker panel is automatically more impact resistant. |
| Dimensional Stability | Check how the panel accommodates temperature changes and whether the instructions specify expansion gaps, acclimation, or limits on panel size and installation conditions. | Review dimensional-change or thermal-performance results where provided, together with the test method and installation guidance for the intended environment. | Follow required expansion gaps and leave movement provisions at edges and transitions. Keep panels within the stated service-temperature range and avoid installation over unsuitable or unstable substrates. |
| Installation and Maintenance | Confirm that the fixing system, substrate requirements, joint treatment, cleaning method, and repair or replacement approach are clearly described. | Request the current installation and maintenance manuals, including approved adhesives or mechanical fixings, surface-preparation steps, and any limitations. | Prefer clear, product-specific instructions and ensure installers follow them. Correct substrate preparation and sealed details are essential to the performance of the finished wall. |
| Documentation and Warranty | Check that claims for water resistance, fire performance, emissions, and durability correspond to the exact product and intended application. | Review dated test reports, certificates, technical data sheets, installation instructions, and warranty terms. Check exclusions, maintenance conditions, and approved-use limitations. | Compare documented performance rather than broad marketing claims. Keep product and installation records for future maintenance and warranty enquiries. |
