Description
The ReductoClip™ system for timber ceilings is tried, tested and proven to provide the highest level of sound reduction. A slimline, highly effective ceiling soundproofing solution, engineered to enable you to achieve peace and quiet in your home.This system ticks all the necessary boxes, adding high levels of mass and resilience to dampen sound energy from the structure.
Whether you want peace and quiet from noisy neighbours, or privacy in your own space, the ReductoClip Ceiling System is the perfect solution.
Features & Specifications
Features:
60mm of High Performing Sound Reduction Engineering
1. ReductoClips – decouple the mass layers from the timber joists and act like a shock absorbing suspension system to dampen high levels of sound energy and vibration
2. ReductoClip Furring Channels – extra wide to make fixing acoustic plasterboards quicker and easier
3. Acoustic Mineral Wool – dampens sound within the cavity to stop sound amplifying
4. Acoustic Plasterboard – (2 layers) to increase the mass of the ceiling. More mass and density than standard plasterboard but with the same finishing and decorating techniques
5.FlexiSound 5 – Anti-Vibration membrane to add further mass to the wall. A different type of mass to reduce different sound frequencies to the other layers. FlexiSound also helps to dampen sound energy and vibration

Delivery
- If you are employing fitters, it’s recommended they are booked after materials have been delivered
- Please note that our products have a great deal of mass, and will add weight to your structure. You may need to check with a structural engineer to ensure compatibility
- Some of the heavy materials will need two people to lift them (unfortunately our drivers won’t be able to assist with carrying materials indoors)
- Standard delivery is between 9am and 6pm and all goods must be signed for
- All goods are delivered (well wrapped) on a pallet as close to your property as possible

FAQ
Does soundproofing a ceiling work?
The ReductoClip ceiling soundproofing solution is designed to exceed the UK Part E Building Regulations for the passage of sound. (43dB or higher for airborne noise and 64dB or lower for impact noise).
Soundproofing a ceiling will reduce the noise from noisy neighbours (e.g. heavy footsteps and loud airborne noise).
*dB results will vary depending on several factors.

What is the best way to soundproof a ceiling?
The best way to soundproof a ceiling follows three main principles:
- Improve the mass of the ceiling. The heavier and more dense the ceiling is, the harder it is for sound to pass through it. Use different high density materials, as different materials are better at blocking different sound frequencies. It is the law of diminishing returns if simply using more of the same material
- Use high impact clips and bars such as the ReductoClip and Furring Bar System which help to absorb sound energy and vibration. Without this the addition of mass will have very little effect on impact noise
- Fill all cavities between joists with acoustic mineral wool. For concrete ceilings use acoustic mineral wool between the concrete ceiling and the first layer of acoustic plasterboard. This will prevent sound resonating and amplifying in this sealed chamber

How much space is lost from the ceiling height?
The ReductoClip ceiling system is the thinnest clip system on the market, with minimal space loss.
The system is only a 60mm build up from the bottom of the timber joist to the final layer of plasterboard.
What lights can be fitted after soundproofing a ceiling?
Cutting holes into soundproofing is always going to create a weakness. Therefore, recessed lighting isn't advisable. Ideally slim LED surface mounted spotlights, or single pendant lighting fixed onto the ceiling is the preferred option over and above lighting inside of the ceiling.
Is it better to soundproof the floor above, or the ceiling?
If possible, the recommendation would be to soundproof the floor above against impact noise (e.g. footsteps). Absorbing impact noise at source (before it enters the structure) is preferable.
Do I need to remove my existing ceiling?
The recommendation would be to remove the existing plasterboard, so it doesn't create a void for any sound to become trapped and resonate inside (the drum effect).
If the ceiling is lathe and plaster, it is also recommended to remove this, expose the cavities between the joists and add acoustic mineral wool within this space.
