Canbast Acoustic

Ideal as Sustainable Acoustic Cavity Fill

Canbast Acoustic is excellent as cavity fill-in in acoustic wall and ceiling constructions. The open fiber structure effectively absorbs sound within the construction and helps reduce unwanted sound reflections. As a result, the material provides a sustainable alternative to traditional acoustic fillings.

Excellent sound absorption

Canbast Acoustic effectively absorbs sound across a broad frequency range. As a result, it reduces echo and improves speech intelligibility in offices, schools, public spaces, hospitality venues, and homes.

Made from natural hemp fibres

Hemp is a fast-growing raw material that requires little water and can be cultivated without pesticides. As a result, hemp is one of the most sustainable natural fibres for construction and interior applications.

CO₂-negative solution

During growth, hemp absorbs more CO₂ than is necessary for the production of the end product. As a result, Canbast Acoustic actively contributes to reducing the CO₂ emissions within construction and renovation projects.

Circular Use of the Plant

Almost the entire hemp plant is given a purpose. The high-quality fibres form the basis for Canbast Acoustic, while other parts of the plant are used for applications including the textile industry and pharmaceuticals.

More Than Just Acoustics

In addition to excellent acoustic properties, Canbast Acoustic also has thermal properties. As a result, the material contributes to a comfortable indoor climate.

Hemp is known as one of the most sustainable raw materials for construction and insulation applications.

• Grows quickly without intensive irrigation
• Requires little to no pesticides
• Absorbs large amounts of CO₂ during growth
• Consists of a renewable raw material
• Supports a circular supply chain

Canbast Acoustic is available in different thicknesses and densities, ensuring a suitable solution for every acoustic application.

• 40 mm - 1100 x 600 mm - High density (100 kg/m³)
• 80 mm – 1100 x 600 mm – Low density (35 kg/m³)
• 100 mm – 1100 x 600 mm – Low density (35 kg/m³)

The different versions offer flexibility for both wall and ceiling constructions. Depending on the desired acoustic performance and available installation height, you can choose the most suitable variant.

Canbast Acoustic is independently tested by Peutz according to the international standard EN-ISO 354:2003.

The measurement results show that the material effectively absorbs sound and thus contributes to a pleasant acoustic in a variety of applications.

Canbast Acoustic is classified according to DIN EN 13501-1 Fire Class C. This classification provides insight into the fire behaviour of hemp wool for various applications. As a result, Canbast Acoustic is not only a sustainable and acoustically effective solution, but also a responsible choice regarding fire safety.

Yes. Canbast Acoustic is widely used as cavity filling in acoustic wall, ceiling, and partition wall constructions. The open fibre structure helps to reduce sound reflections within the construction and contributes to better acoustic performance.

Canbast Acoustic is available in low density (35 kg/m³) and high density (100 kg/m³). The correct choice depends on factors such as available installation depth, construction setup, and desired acoustic performance. Our specialists are happy to advise you on the most suitable variant.

The panels are easy to cut to size with a serrated knife. As a result, they can be easily adapted to the dimensions of a wall, ceiling, or partition construction.

Hennepwol is a bio-based raw material that stores CO₂ during growth and can be cultivated with relatively little water and pesticides. As a result, interest in hemp as a sustainable alternative is increasing within construction and renovation projects.

Yes. Canbast Acoustic is suitable for both new build and renovation projects. Thanks to the various thicknesses and densities, the material can be used in a wide range of wall, ceiling, and partition wall constructions. In addition, the product combines effective sound absorption with the benefits of a bio-based raw material, making it an interesting choice for projects where both acoustic comfort and sustainability are important.
