Key Benefits

• Decoupled ceiling system — MuteClip isolation clips and channel create a resilient connection that reduces vibration transfer from the existing structure into the new ceiling, improving airborne sound insulation performance
• High mass build-up — 10kg/m² MLV combined with two layers of 15mm Knauff Soundshield acoustic plasterboard adds significant surface mass, reducing the transmission of loud airborne noise including music, bass, and impact sound
• Suitable for timber joists and concrete soffits — the system is designed to work with both construction types, making it applicable to flats, houses, and commercial spaces
• Complete system supply — all components are included in the calculator output except fixings, so you can order everything needed for your ceiling soundproofing project in one place
• Built-in 5% waste allowance — calculator quantities include a 5% overage to account for cuts and waste, reducing the risk of under-ordering on site
• Competent DIY achievable — a full installation guide is available, covering clip spacing, channel layout, plasterboard fixing sequence, and airtightness sealing

Important Notes

• This is an experienced DIY system.
• Correct clip spacing, channel layout, and fixing selection matter for performance.
• Results will vary depending on the existing ceiling construction, joist spacing, void depth, and flanking paths (walls, floors, services).
• Sealant quantities are an approximation only and should be treated as a guide.
• The calculator is provided as a guide only, and final quantities should always be checked before ordering.
• If there are recessed lights, services, or penetrations, these can significantly reduce performance unless treated correctly.

Installation Summary

• Set out battens (if required) and fix to concrete using anchor bolts (concrete ceilings only)
• Fix MuteClips to joists or battens using 5mm x 60mm coarse thread wood screws
• Install MuteClip Channels and secure overlaps using 20mm steel self-tapping screws
• Fix the first layer of 15mm acoustic plasterboard to channels using 32mm fine thread drywall screws
• Install 10kg MLV as part of the ceiling build-up
• Fix the second layer of 15mm acoustic plasterboard using 50mm fine thread drywall screws
• Tape joints and seal perimeter gaps with AC95 for airtightness
