Perfopan
Perfoline® Grooved Panels
Perfopan Perfoline is a grooved wood panel for walls and ceilings that absorbs sound. Grooves are cut into the face and holes are drilled from the rear, so auditoriums, conference rooms, boardrooms and reception areas get controlled reverberation with a timber finish.
Six variants run from 8% to 16% perforation ratio at 4,000 to 8,000 holes per m². One targets low and mid frequencies, one low, mid and high, and four mid and high. Every panel has a fire-resistant acoustic fabric backing.

Where it works, fire rating and fitting
Your product questions, answered, for UK schools, offices and venues.
One variant targets low and mid frequencies, one covers low, mid and high, and four target mid and high. We match the variant to the frequency problem in your room and its reverberation target, rather than assuming one will do.
Yes. It is used in auditoriums, conference rooms, boardrooms and reception areas, and the same logic applies to school halls, offices and restaurants. For schools we assess the choice against the BB93 target at the survey.
Each panel is backed with a fire-resistant acoustic fabric, but we do not quote a classification without the data sheet. We confirm it against your building's requirements before ordering, and Perfofire Grooved Panels are the matching range where a fire-resistant core is required.
Six patterns, from 2mm to 4mm groove gaps, with 8mm rear holes at 4,000 holes per m², or a stepped 3mm front and 8mm rear hole at 8,000. Panels can also be made to custom sizes or at large scale.
Our installation team confirms the fixings for your wall or ceiling at the survey. Samples are available on request; allow a few working days. The free site survey also gives a quotation and an AI-assisted acoustic report.
