We recommend ordering areas individually and adding them to the basket rather than adding them to one large area. You can order multiple areas in the same order.

Airborne Data

Untreated Ceiling Airborne DnT,w

200mm concrete ceiling 59db

Treated Ceiling Airborne DnT,w

AcoustiClip Concrete Ceiling System 72dB

Improvement DnT,w

Noise reduction with treatment 13dB

Impact Data

Untreated Ceiling Impact LnT,w

200mm concrete ceiling 76dB

Treated Ceiling Impact LnT,w 

AcoustiClip Timber Ceiling System 48dB

Improvement LnT,w

Noise reduction with treatment 28dB

Note: Every 10 decibels(dB) reduction in noise level is roughly perceived as a halving of the perceived loudness. So, for instance, if you have a sound that measures 70dB and it decreases to 60dB, it would sound about half as loud to the human ear. Decibels Explained.

• Fix the AcoustiClip by screwing them directly into the concrete ceiling. Alternatively, fix timber battens to the ceiling and screw the AcoustiClip into the timber batten. See the diagram below for clip and channel spacing.
• An AcoustiClip should be installed at the end of each row.
• The AcoustiChannel is inserted into the clip by pushing it into the AcoustiClip.
• The AcoustiChannels are joined, overlapping them 100mm.
• Lay the acoustic insulation between the AcoustiChannel. Adhere the insulation using a strong spray adhesive between the channels. Alternatively, slide the insulation over the back of the first layer of boarding.
• Once the AcoustiChannel is in place, you can attach the soundboards. Screw the boards into the AcoustiChannel using drywall screws. We recommend using a minimum of 16 fixings per board. Ensure the screw punctures the AcoustiChannel by a minimum of 10mm.
• Affix the 15mm soundboard first and then the Noisestop 1 Plus Panel, sandwiching the acoustic membrane between the soundboards on the back of the Noisestop 1 Plus Panel.
• Once the boards have been fitted, the system can be finished as you would finish standard plasterboard. The boards are supplied with tapered edges, which allows for dry-lining or plastering.

Spacing the AcoustiClip & AcoustiChannel

• Maximum 600mm centers between the AcoustiChannel
• Maximum 900mm centres between AcoustiClips along the AcoustiChannel
• Maximum 150mm from the centre of the AcoustiChannel and the wall
• Ensure the end of the AcoustiChannel does not contact the wall

The best method of soundproofing a ceiling is to use a combination of products in a soundproof system.

Soundproof systems will add mass, increase sound absorption and decouple the existing structure from the new.

We recommend using the AcoustiClip system to soundproof your ceilings. The combination of materials supplied with the AcoustiClip Timber Ceiling System comprises all the required products to sound insulate the ceiling against impact and airborne sounds effectively.

The best-performing timber joist ceiling solution is the Acousticlip Timber Joist System.

The product combinations supplied with this system achieve a high level of noise reduction against airborne and impact sounds.

Timber joist ceilings will benefit from the AcoustiClip’s decoupling effect and the increased mass/density and sound absorption of soundproof panels and acoustic insulation.

The best-performing sound insulation system for concrete ceilings is the Acousticlip Concrete Ceiling System.

The product combinations supplied with this system achieve a high level of noise reduction against airborne and impact sounds.

Concrete ceilings will benefit from the AcoustiClip’s decoupling effect and the increased mass/density and sound absorption of soundproof panels and acoustic insulation.

Unless you have very high ceilings, you will probably need to remove the plasterboard or lathe and plaster to soundproof your ceiling effectively.

Removing the existing ceiling will allow you to use acoustic insulation inside the ceiling joist, which is a great way to add mass. Using the AcoustiClip system, you will decouple the ceiling, which isolates the joist from the new ceiling.

Removing the ceiling means you can use the AcoustiClip Timber Ceiling System, our recommended solution.

If you are using downlighters in your ceiling, you should fit acoustic/fire hoods over the lights to ensure the acoustic integrity of the ceiling.

Stopping impact sound through the floor above is difficult to stop from below. In an ideal world, you would soundproof the floors to stop the impact sound. If you can’t access the floor, the best solution is to install a ceiling isolated from the existing.

If you have very high ceilings, you could install a completely new ceiling with joists without connection to the existing ceiling. If this option does not apply, you must use a system that isolates the new ceiling even if it is in contact with the joist.

The best solution for achieving isolation is to use The AcoustiClip Timber Ceiling System.
