Compare the whole supply chain
For wood, ask about species identification, origin and supply documentation. For manufactured boards, ask about feedstock, binder or polymer, manufacturing impacts and realistic end-of-use routes. Bamboo growth rate is only one part of an engineered product’s footprint. Recycled content does not automatically mean the finished board can be recycled locally.
Read environmental evidence carefully
Prefer product-specific environmental documents with a stated functional unit and scope. Comparisons need comparable boundaries: transport, maintenance and end of use can change conclusions. Do not combine a manufacturer’s best-case scenario for one product with a worst-case scenario for another. This site does not certify products or establish chain of custody.
Warranty is a contract
Read the named product warranty for owner type, registration, transfer rules, exclusions, proration, labor coverage and claim procedures. Structural, stain and fade provisions may be separate. Keep the invoice, product line and color, installation records and maintenance evidence. A warranty term is not a verified service-life estimate.
Fire and code questions
Do not assign a fire classification or approval to a whole material family. Ask the local authority and responsible designer for the exact documents required for the product and assembly. Flame-spread evidence, wildfire requirements and structural acceptance address different questions. This resource does not award fire ratings.
