Decrasound Ceilings – Acoustic Ceiling Panels for Commercial Spaces
Decrasound acoustic ceiling panels are designed to improve speech clarity and reduce unwanted echo in modern interior environments. Whether it’s an office, school, retail space, or hospitality venue, our panels are lightweight, easy to install, and available in a range of styles to suit ceiling-mounted configurations.
Manufactured from high-performance polyester fibre (PET), these panels contribute to improved indoor air quality and are certified for low VOC emissions. The ceiling range includes baffles, rafts, and tile systems that blend well with most ceiling grids or suspension designs. With a choice of colours, sizes, and NRC values, you can tailor the acoustic performance to meet your specific project goals.
Decrasound Ceilings are ideal for environments where acoustic comfort and visual aesthetics need to work hand in hand.

Acoustic Performance
Decrasound Decrabaffle provides maximum design flexibility coupled with functional performance, allowing effective control of reverberated noise within building interiors. Main baffle spacing options of 100mm, 200mm, and 300mm can be selected, each delivering different levels of sound absorption.
For critical reverberation control, maximum acoustic absorption can be achieved with baffles spaced at 100mm. For less demanding applications, 200mm or 300mm spacing may provide a suitable and more economical alternative.
