What Is
Bowiq Acoustic Plaster?
As part of our extensive acoustic plaster range, we install Bowiq Acoustic Plaster Spray throughout the UK. Perfect for use in offices, restaurants, auditoriums, swimming pools and other large areas where noise levels and echoic reverberating spaces need to be controlled with soffit treatment or high-level walls.
Bowiq’s premium acoustic products, such as BoSpray, are environmentally friendly solutions that produce a seamless application. BoSpray is available in a range of modern colours, including Light Grey, Eco Dark Grey, Black and White, providing excellent acoustical properties with a stylish finish.
BoSpray is a high-end water-based acoustical spray based on recycled cellulose. It can be applied to 40mm in a single application, with a sound absorption NRC of 0.65 at 25mm and at 40mm, an NRC of 0.9 is achieved, with a fire-resistant class of Bs1 d0 (according to EN 13501-1); providing an effective solution with a seamless finish.

BoSpray
A very effective cellulose based acoustical spray plaster that creates a seamless acoustical ceiling. The ideal acoustical solution for “open” ceilings that need an acoustic ceiling product that’s fast and efficient in the application.
Because often designs use hard materials on floors and walls, the acoustics isn’t optimum. This affects heavily how you will experience a space. Especially places where more people come together. There are ways to improve the acoustics. An acoustic spray is one of ways to correct the acoustics in a space.
Fire-resistant class: Classification: B s1 d0 according to EN 13501-1 & ASTM E84 Class A.
Specification
Fire Safety
Classified according to EN 13501-1 as B-s1,d0, with additional compliance under ASTM E84 Class A. The system is formulated without hazardous additives or brominated flame retardants, ensuring safe use in both renovation and new-build applications.
Sustainability
Manufactured with approximately 80% pre-consumer recycled cellulose fibres and water-based binders. Free from Red-List materials and heavy metals, and compliant with low-VOC requirements. Contributes to LEED, BREEAM and WELL through recycled content, indoor air quality, ingredient transparency and acoustic performance.
Colour Appearance
Available in Light Grey, Eco Dark Grey, Black and White as standard, with full RAL or NCS colour matching on request. Compatible with Acoustical Coat for refreshed or customised finishes without reducing acoustic absorption. Smooth, low-gloss surface supports calm visual integration.
Installation
Applied using a dedicated cellulose fibre spray-binder system capable of achieving 40mm in a single pass. Suitable for curved surfaces and complex geometries. Fast-setting formulation supports efficient coverage for large-scale interiors.
Substrate Requirements
Substrates must be dry, stable and free of dust or loose particles. Holes and cracks require full closure, and deviations greater than 3 mm must be levelled prior to spraying. Metal or plastic edge profiles should be installed to define boundaries.
Acoustic Data
Performance varies with applied thickness. Typical values include NRC 0.55 at 10 mm, 0.65 at 15 mm, 0.85 at 25 mm, and 0.95 at 40 mm. Rib-deck applications achieve an NRC of 1.00. Frequency-based absorption supports balanced sound control.
Application Areas
Suitable for community spaces, education, hospitality, sports facilities, offices, swimming pools and transport-related structures where acoustic comfort and seamless aesthetics are required.
Technical Properties
Lightweight plaster with an average density of 65 kg/m³ and thermal conductivity of 0.038 W/(mK). Water-based composition ensures low environmental impact and supports high-build application in a single layer.
Application
Suitable for both new construction and renovation projects, as long as the acoustic experience plays an important role, such as:
- Community spaces
- Classrooms
- Restaurants
- Sports venues
- Auditoriums
- Car parks
- Offices
Features Of
LEED, BREEAM and WELL
LEED (Leadership in Energy and Environmental Design), BREEAM (Building Research Establishment Environmental Assessment Method), and WELL (WELL Building Standard) are sustainability certification programs for buildings, helping to achieve environmentally-friendly building design and construction practices.
BoSpray meets the demands of these certification programs in the following areas:
- Water-based
- Highly recycled content
- Low VOC (Volatile Organic Compound) levels
- Thermal conductivity coefficient: d=0.038 W/(mK)
- Average density: 65kg/m³
- Excellent acoustical properties
- Insulation properties
- No harmful substances
- HPD (Health Product Declaration)
Acoustic Colour Design
Colours are a vital part of the design of any building, and ceilings are a part of that room or building. An acoustic spray can not only make a significant contribution to creating a sound acoustic space, but can also enhance the design with a specific colour.
Therefore, BoSpray can be supplied in any colour of your choice. With the help of the Acoustical coat, we can also apply a fresh coat on top of an acoustical surface in order to match a specific colour or give the surface a new or fresh look
Acoustical Coat
The coating that can refresh or change the colour of your acoustical plaster with out affecting the acoustical properties.
