Rafts are horizontal panels suspended parallel to the ceiling. They act like “acoustic islands”, absorbing sound that reflects upwards and sound bouncing back from the soffit. Rafts are a great choice for offices, classrooms, and meeting spaces where wall space is limited but ceiling surfaces are free. They often offer the best value for money due to the large surface area of absorption they afford.

They can be square, circular, or custom-shaped, and are available in many finishes to integrate with lighting and HVAC systems. Rafts combine strong acoustic performance with a sleek architectural look — making them one of the most popular solutions we install at Resonics.

Acoustic ceiling rafts are an ideal solution for both open-plan spaces with low ceilings and smaller rooms with high ceilings. These panels are designed to enhance speech clarity, reduce echo, and minimise reverberation, creating a more acoustically comfortable environment.

The cost of acoustic ceiling rafts depends on factors such as size, quantity and material choice. We offer solutions to suit a range of budgets, with bespoke options made from high-quality materials. To get an accurate estimate, we recommend booking a free acoustic survey. This allows our specialists to assess your space and provide a tailored quote.

The more space the better. However, this is always subjective to the individual needs of the project. Generally we aim to evenly space panels on the ceiling to ensure consistent absorption throughout the space. Don’t cluster them all together, as this will create hot and cold spots within the room which is not what you want!

Yes, acoustic panels work on ceilings. Treating the ceiling area is the most effective way to reduce echo and reverberation especially within larger open spaces. We always look to treat the ceiling first and foremost.

Yes. All products we install are fire-tested to European standards (typically EN 13501-1 Class B-s1,d0 or equivalent). We only specify panels that are safe for use in offices, schools, restaurants, and public buildings.

Yes. Many of our panels are made from recycled PET (plastic bottles) and are 100% recyclable. We also work with suppliers committed to sustainable manufacturing, low-VOC materials, and long product lifespans. Choosing PET panels reduces landfill waste while providing excellent acoustic performance.

Some panels, like lightweight stick-on absorbers, can be DIY-installed. However, professional installation is strongly recommended for ceiling systems, large projects, or anywhere safety access is needed. Incorrect fixing may compromise both safety and performance. If you are determined to install yourself, get in touch and we will point you in the right direction.

Resonics provides a full supply-and-fit service across the UK, using qualified installers to ensure compliance with building and fire regulations. We also guarantee the quality of our installations — something you won’t get with DIY.

Yes. Our proposals include predicted reverberation times (RT60) based on room dimensions and materials. Post-installation, we can carry out acoustic testing to verify performance. All products come with manufacturer test certificates showing absorption coefficients.
