Perfopan
Microustic® NANO-MICRO 4x4x0.5 PR3%
Microustic® NANO-MICRO 4x4x0.5 PR3% is a Perfopan wood panel with Ø0.5mm front holes on a 4 × 4mm grid and a 3% open area. Half the diameter of the MICRO models' holes, the perforation is even harder to pick out, so the surface reads as plain veneer or lacquer. It suits boardrooms, hotel lobbies and display walls where the finish leads and absorption is planned around it.
The 18mm MDF board is drilled from both faces, backed with Soundtex black glass tissue and fixed on an aluminium profile. Perfopan tested it at a 200mm mounting depth with 30mm of 30 kg/m³ mineral wool; its NRC is confirmed from the data sheet at specification. Finishes are wood veneer, HPL or lacquer to a RAL colour.

Where it works, fire rating and fitting
Your product questions, answered, for UK schools, offices and venues.
It suits boardrooms, hotel lobbies and feature walls where the surface should look like plain timber or lacquer. Our acoustician checks how much absorption the room needs against its RT60 target, and against BB93 for a school, at the survey.
Perfopan's data sheet gives D-s2,d0 for the standard 18mm MDF board and B-s2,d0 for the fire-resistant MDF board. We check the chosen board and finish against your building's fire strategy before anything is ordered.
Perfopan's documents give different NRC figures for this model, so the value is confirmed from the data sheet at specification. Its published test used a 200mm mounting depth with 30mm of 30 kg/m³ mineral wool.
Panels fix on an aluminium profile, and the depth of the cavity behind affects the result; Perfopan tested at 200mm. Our installation team confirms the substructure at the survey and sets out the panels on site.
Samples are available on request; allow a few working days. Quantities come from the room's size, finishes and use at the free site survey, which gives a quotation and an AI-assisted acoustic report. Before-and-after acoustic measurement is available as a paid add-on.
