Product Comparison Review
Product comparison review based on evidence, not assumptions.
The Bench reviews product and system evidence where two or more routes are being compared for a defined construction question.
We help separate real evidence differences from marketing claims, incomplete comparisons or assumptions that do not match the proposed use.
Comparison basis
Products can only be compared against the same question.
Evidence basis
We compare the type and relevance of available evidence, including test reports, certificates, classifications, data sheets and system details.
Application limits
We check whether the evidence relates to the same substrate, thickness, fixing method, build-up, exposure, performance route or project condition.
Gap position
We identify where one product route has clearer evidence, where evidence is missing, and where further confirmation is needed.
Typical comparison areas
Useful where a simple like-for-like answer is not safe.
Boards and sheathing
Comparison of board evidence, racking evidence, reaction to fire evidence, fixing details or project-specific use limits.
Fire and performance routes
Comparison of fire evidence, classification scope, test routes, build-up differences and stated limitations.
Thermal and build-up options
Comparison of U-value routes, insulation options, thermal conductivity values and total system build-up implications.
Façade and wall systems
Comparison of carrier boards, renders, brick slips, cladding support, backing layers and system evidence.
Installation differences
Review of fixing, jointing, substrate, thickness, support centres, exposure and build-up differences that affect evidence transfer.
Evidence confidence
Clear separation between direct evidence, partial evidence, assumptions and missing information.
Output
A clearer comparison note.
A product comparison review can summarise what each route appears to support, where the evidence differs, what assumptions should be avoided and what further information may be needed.
The Bench does not approve, certify, specify or formally select products. The review is an evidence-led technical support output for discussion and decision-making by the relevant project parties.
