The number of panels required depends on the size, shape, and materials in the room, as well as the intended use. A small meeting room might need as few as 6–8 wall panels to one wall, while an open-plan office could require dozens of ceiling baffles or rafts. The aim is to reduce the reverberation time to a comfortable level, not to cover every surface.

Walls: Good practise is to apply panelling from skirting to ceiling to 2no. perpendicular walls to reduce flutter echoes.

Ceilings: In accordance with new BS ISO 22955:2021 guidelines, the ceiling is the most important treatment area, and should feature approximately 50-60% Class A coverage in open plan office spaces.

Resonics provides a free acoustic survey and CAD layout to determine exactly how many panels you need and where they should go. This ensures you invest only in what’s necessary to achieve measurable results.

Not much. Most panels are made from durable, stain-resistant materials such as PET felt or fabric-wrapped glass wool. They can be lightly vacuumed or wiped with a damp cloth to remove dust. Unlike soft furnishings, they don’t need regular deep cleaning.

Panels should not be painted, as this can block their sound-absorbing pores. If a panel becomes damaged, it can be replaced individually without affecting the wider system. PET panels, in particular, are highly durable and maintain their acoustic performance for many years.

Yes. All panels we install are tested to meet international fire safety standards. Most are rated to EN 13501-1:2007+A1:2009 (Class B-s1,d0) or equivalent. This ensures they do not contribute to flame spread or smoke production.

Additionally, many panels are low-VOC certified, non-toxic, and safe for use in sensitive environments such as schools, healthcare spaces, and homes. At Resonics, we only work with manufacturers that prioritise safety and compliance.

The best placement depends on how the room is used:

• Offices/meeting rooms: first reflection points (side walls and ceiling above desks). Ideally on 2 perpendicular walls to reduce flutter echo.
• Restaurants/classrooms: spread evenly across walls and ceilings to avoid “hot spots”. Ideally above 50% of the ceiling area using Class A products.
• Studios: direct reflection points behind and beside speakers/microphones.

Ceilings are often the most effective surface because they are large, open, and unobstructed. Our free CAD proposals include detailed layouts showing the exact recommended panel placement for maximum performance.

Yes. Acoustic panels are proven to work — they absorb sound energy, reducing echo and controlling reverberation in a room. Without acoustic treatment, sound bounces around hard surfaces such as glass, plaster, concrete, or wood, creating a noisy and tiring environment. Panels are made from sound-absorbent materials that trap and dissipate this energy. The result is speech clarity, calmer background noise levels, and a more productive atmosphere. At Resonics, we only use panels tested in independent acoustic laboratories, ensuring their performance is certified and measurable. With more than 5,000 completed projects across the UK and Europe, we’ve seen first-hand how transformative they can be in offices, schools, restaurants, and community spaces.
