PET acoustic panels for walls and ceilings
Our plain PET acoustic sheets are 9 mm polyester felt boards made from recycled PET fibre. Each sheet is 2400 × 1200 mm (8 × 4 ft), 9 mm thick, NRC 0.75–0.85, fire rated Class A/B to ASTM E-84, weighs 5.3 kg and covers about 2.98 m² (32 sq ft). They come in 48 colours across six families: whites and greys, skin tones, yellows and oranges, reds and purples, blues, and greens.
Use them as acoustic wall cladding, as false-ceiling panels, as partitions or as pinboards. PET felt is light, cuts to any shape with a knife, does not shrink or stretch with humidity, and resists moisture, mould, insects and bacteria.
Frequently asked questions
What is a PET acoustic panel?
A PET acoustic panel is a felt board made from compressed polyester (PET) fibre, much of it recycled from plastic bottles. Its open fibre structure absorbs sound instead of reflecting it, which cuts echo and reverberation in a room. A 9 mm Numobel PET sheet has an NRC of 0.75–0.85, meaning it absorbs roughly 75–85% of the sound that reaches it.
Acoustic panels vs soundproofing: what is the difference?
Acoustic panels treat the sound inside a room: they reduce echo so speech and music sound clearer. Soundproofing stops sound passing between rooms and needs mass and airtight construction (walls, doors, windows). Most offices, studios, classrooms and home theatres need acoustic treatment first.
How many acoustic panels do I need?
As a starting point, cover 15–25% of the wall area of a meeting room or home theatre, and 25–40% of a large open office, hall or restaurant (walls and ceiling together). One 8 × 4 ft sheet covers about 2.98 m² (32 sq ft). Send us your room size on WhatsApp and we will suggest a layout.
How are PET acoustic panels installed?
Sheets are fixed to a wall with adhesive or double-sided tape, or screwed to a frame, and cut on site with a sharp knife. They can also be used as false-ceiling tiles or pinboards. PET does not shrink, stretch or grow mould in humid weather.
