Perfopan
Perfoball® Perforated Wall Panels
Perfopan Perfoball is a perforated wood panel for walls and ceilings, with hole patterns from 1,000 to 16,000 per m² that set the frequencies it absorbs. Certified fire-resistant acoustic fabric backs every panel, for halls, classrooms and meeting rooms.
Five variants use 8mm holes, or a stepped 2mm front and 8mm rear hole on the 16,000 per m² panel. Custom and large-scale sizes are made on request, and Perfofire perforated panels are the matching range with a fire-resistant core.

Coarser 1,000 and 2,000 holes per m² patterns work in the low and mid range, finer 4,000 and 8,000 patterns in the mid and high range, and the stepped variant targets low frequencies. Our acoustician matches the variant to your room's RT60 target.
Every panel is backed with certified fire-resistant acoustic fabric. We confirm the classification of the chosen board from Perfopan's data sheet, and Perfofire perforated panels, rated A2-s1,d0, are the alternative where a fire-resistant core is required.
Panels fix on Perfopan's wall installation systems, and the cavity behind affects absorption. Our installation team confirms the substructure and cavity at the survey, then agrees the setting out on site so patterns line up across the surface.
Holes are 8mm, or 2mm front and 8mm rear on the stepped variant, in patterns such as TD 32x32x8 and TD 16x16x8. Custom and large-format sizes are available on request.
Samples are available on request; allow a few working days. Quantity depends on room size, ceiling height, hard surfaces and use, so our acoustician assesses the space at the free site survey and you receive a quotation and an AI-assisted acoustic report.
