Sunda Raft Square

The installation process for our Sunda Raft panels is both simple and efficient, requiring no specialised fitter. These acoustic rafts are easily suspended from the soffit using steel cables, facilitated by unique spiral hooks securely embedded into the raft’s reverse via clockwise rotation.

Adjusting the height level is easily achieved by manipulating the length of each cable upon insertion into the clip hook. Moreover, for enhanced design flexibility, Sunda Raft can be set at various angles to suit aesthetic preferences.

To ensure proper installation, spiral hooks should be positioned approximately 200mm inward from the edge of the Sunda Raft panel.

Included within our hanging kit are a Top Hat fixings (bullet which screws into the ceiling), 2m Adjustable Wires, eyelets (this is to feed the wire through) and Spiral Hooks (anchors into the rear of the raft), providing all necessary components for a seamless installation process.

Determining the optimal quantity of Sunda Raft isn’t an exact science. Broadly, increased surface coverage leads to greater sound absorption and reduced echo. As a general guideline, aiming to cover approximately 30% to 50% of the ceiling area typically results in effective sound absorption.

You can use our reverberation calculator as a helpful tool in this process.

Sunda Raft is made using a dense glass wool core of which offers high levels of sound absorption and is also a sustainable material, the face of Sunda Raft is a high-quality fabric to give a premium finish and offers a wide variety of colour choice.

Each Sunda Raft order will come with the correct amount of hanging kits. These kits consist of a Top Hat fixing (bullet which screws into the ceiling), 2m Adjustable Wire, Clip (this is to feed the wire through) and a Spiral Hook (anchors into the rear of the raft). The only fixings you will need in addition to these hanging kits are the screws to attach the Top Hat fixing to the soffit. We do not supply these screws as the appropriate screws will dependant on your soffit structure i.e. Plasterboard, concrete, timber which your local DIY store will be able to recommend.

We use Camira Lucia as standard, but we can manufacture using alternative fabrics on request.

Yes, although we have a standard range of the most popular sizes it is possible to have a customised shape or size of the Sunda Raft to suit your requirements.

However, there are some limitations in these shapes and max sizes that are possible to manufacture due to weight and panel size. Please get in touch to discuss what’s possible.

When installing Sunda Raft, you should consider the mounting surface. The right surface should ensure a secure, long-lasting installation.

Suitable surfaces include:

• Drywall: Attach rafts using suitable screws, ensuring the drywall is in good condition.
• Concrete: Use appropriate fasteners like concrete screws or anchors to securely attach baffles.
• Plywood: Mount rafts directly or install plywood as a substrate over other surfaces.
• Metal Studs: In commercial/industrial spaces, attach rafts directly to metal studs using suitable screws.
• Suspended Ceiling: Fix through the ceiling tile and then into a timber pattress for support or use lighting/signage clips to suspend from the ceiling grid.
• Exposed Beams: In open spaces, use clamps or brackets designed for beam mounting. Ensure the surface is clean, dry, and capable of supporting the rafts’ weight.

You can follow our installation guide for a full step by step installation found on our data sheet.

The only fixings you will need in addition to the supplied hanging kits are the screws to attach the Top Hat fixing to the soffit. We do not supply these screws as the appropriate screws will dependant on your soffit structure ie. Plasterboard, concrete, timber which your local DIY store will be able to recommend.

Sunda Raft comes with a one-year manufacturer’s warranty, providing coverage for any defects in materials or workmanship. This warranty is to ensure peace of mind for our customers, guaranteeing reliable performance and quality assurance.

Yes, Sunda Raft core board has been tested and offers EN 13501-1:2018 A2-s1, d0 and Class O fire rating to BS476: Part 6. Fabric facing complies with EN1350-1 Class B, s1, d0.

Sunda Raft effectively absorbs direct sound and reflections from ceilings and upper wall sections. While it doesn’t address noise transfer between rooms, it noticeably diminishes noise within an open area. Installing the appropriate number of rafts achieves significant results, reducing echo and reverberation for a quieter, more tranquil atmosphere.

Calculate the estimated quantity needed for your space and discover what results could be achieved using our reverberation time calculator.

Sunda Raft has great acoustic properties and has up to Class A Sound Absorption rating. For a breakdown of acoustic performance tested against different frequencies, please see our datasheet in the downloads section.

Sunda Raft is manufactured in and shipped from the UK.

Sunda Rafts offer versatile solutions for spaces affected by reverberation and echo, particularly those with speech clarity and noise volume issues. Suited for various environments such as offices, meeting rooms, hotels, restaurants, village halls, schools, lecture theatres, music studios, and rehearsal spaces. These high-performing acoustic rafts effectively enhance room acoustics by addressing noise that typically rises to the ceiling, minimising reverberation and reflected sound. They are especially beneficial in areas with limited wall space.

Yes, the wire hanging kits provided with the Sunda Raft are adjustable meaning that you can easily alter the height by simply pressing down on the clip that the wire feeds through. We recommend a minimum suspension drop of 150mm-200mm for optimal acoustic performance.

Yes, samples are available for Sunda Raft. We can arrange for a product sample and a fabric swatch to be sent out to you on request to help you make your decision. Please contact us to arrange.
