PET and Wood Wool Acoustic Panels: Specification Comparison
By Thermofriz Team · Updated 25 October 2026
Compare PET and wood wool acoustic panels using assembly data, design, substrate, fire evidence, care and project constraints.
Compare products with matching evidence
Material labels describe broad families rather than a guaranteed acoustic outcome. Obtain the thickness, density where relevant, backing and mounting for each proposal. Review frequency-dependent absorption as well as any single-number summary. A direct-mounted product and a cavity-backed system are different comparisons even when their visible thickness is similar.
Review architectural and practical differences
Consider edge details, colours, surface texture, cutting, joint alignment and the supporting construction. A lightweight decorative form may solve a different design need from a rigid board finish. Check impact exposure, moisture conditions and cleaning expectations for the actual location. Obtain samples and product-specific guidance rather than assuming all versions of a material behave alike.
Include the complete installed scope
Compare supply, backing, framing, fixings, trims, installation and access requirements together. Request applicable fire evidence and any environmental declarations before making related claims. Confirm spare material and replacement procedures. Thermofriz can discuss both selection and contracting scope, with the final recommendation based on the particular products and project requirements.
