Improve room acoustics without complicated installation with these self-adhesive acoustic wall panels. Each 5 cm pyramid-profile panel is made from 35 kg/m³ high-density polyurethane foam with an NRC 0.8 rating, absorbing up to 80% of reflected sound to help reduce echo and reverberation. Ideal for home offices, studios, gaming rooms, podcast setups and TV rooms. The peel-and-stick backing allows quick fitting on clean, dry, smooth surfaces; panels can be trimmed around sockets, corners and edges with scissors or a sharp utility knife. Panels arrive vacuum packed to reduce packaging size – unpack before installation and allow 24–48 hours to regain their full pyramid shape. SGS testing found no detected formaldehyde or selected soluble elements in the tested sample. The polyurethane material is specified as B1 grade flame-retardant. Available in 12, 16, 20, 24, 28, 32, 36 or 48 pack (1.08 m² – 4.32 m² total coverage). Designed for acoustic treatment inside a room; helps control echo but is not a structural barrier and will not fully block noise passing through walls.

Panel size 30 x 30 cm (0.09 m² per tile). Thickness 5 cm. Profile: pyramid. Material: high-density polyurethane foam at 35 kg/m³. NRC 0.8 sound absorption rating. Fire rating: B1 flame-retardant. Colour: black. To install, wipe wall surface clean of dust, dirt and grease and allow to dry fully. Peel adhesive backing and press panel firmly onto the wall from centre outwards. Trim edges to fit around sockets, corners and skirting using scissors or a sharp utility knife. For textured wallpaper, painted brick or uneven walls, use additional spray adhesive, staples or double-sided foam tape for a secure hold. Store unopened vacuum-packed sets in a dry, cool place. Allow 24–48 hours for panels to fully expand after unpacking. Wipe clean with a dry or slightly damp cloth. Avoid solvents, bleach and abrasive cleaners. Not suitable for outdoor use, high-humidity environments (bathrooms, saunas) or areas exposed to direct heat sources. Keep away from naked flames despite B1 flame-retardant rating.
