A composite acoustic underlay manufactured from a 100% recycled blend of cork and EVA
MuteMat LVT 650 - 1.6 is a low weight and low gauge acoustic underlay with excellent impact sound reduction for use under Luxury Vinyl Tiles (LVT). The product has consistently achieved impact sound reduction of 18dB in tested with a standard 2.5mm LVT helping to reduce sound transmission between floors or dwellings.
The MuteMat LVT 650 - 1.6 is simple to install and is adhered to the subfloor before adhering your choice of LVT floor finish to the top, for more detailed information see the installation tab above. The product is also ideal for use with underfloor heating with a low tog rating of just 0.15 making it suitable for a wide range of applications and installations. The Ultra thin gauge of the product helps to reduce finishing heights and to optimise indentation recovery. The material requires bonding to both the subfloor and the final floor finish and therefore forms a permanent solution and part of the building structure. The manufacturing of the product is tightly controlled to provide a consistent density and material for lasting and even performance across the material.
iKoustic provide excellent customer service and nationwide delivery, supporting you and your project from planning through to installation and anything along the way, the technical team are just a call away. At iKoustic we are very conscious of our impact on the environment, we are therefore happy to confirm that the MuteMat LVT 650 - 1.6 is made from 100% recycled materials from the cork and sports shoe industries.
As soundproof material, MuteMat® LVT 650 - 1.6 provides a separating layer from the structural floor, which helps to greatly reduce impact noise such as footsteps. The product is strong, lightweight and flexible making installation very straightforward while maintaining a high level of impact reduction from a product only 1.6mm thick.
The subjective nature of noise means that a problematic or irritating noise for you will not be the same for others. Your sensitivity to a specific sound or event will vary, and this could be disruption from footsteps above if you have any question about sound issues and how best to treat them please get in contact with a member of the technical team.
*Our Typical Performance Results and Noise Reduction Guidance are provided to indicate the results that have been achieved in previous tests but are not guaranteed to a specific site as multiple factors can affect this, please get in contact with any queries.
We endeavour to display the most up to date testing and assist in managing your expectations through each stage of the process so that the choice we make is the right one.
The floor must be prepared prior to installation by ensuring all surfaces are level and smooth, free of dust and debris and any holes / cracks or similar filled and sealed with acoustic sealant.
The product must be allowed to acclimatise to the environment for 24 hours prior to installation, the temperature of the room should be at least 18°C and relative humidity below 75%. In general working practices outlined in (BS8203: 2017 Code of practice for installation of resilient floor coverings) should be followed.
Flanking issues can seriously detract from the performance of acoustic flooring, this occurs where sound is able to bypass flooring treatments through adjoining surfaces or through a weak area of the structure. This can both reduce the quality of the flooring and detract from the performance when looking to pass Part E Building requirements. Ensure that the junction between floor and wall contains no defects and the structure and build up of the wall and floor structure does not negatively affect the underlay and floor treatment.
Installation (MuteMat LVT 650 - 1.6)
The ideal installation temperature is between 18-35°C with a maximum air relative humidity of 65%. The subfloor temperature should not fall below 10°C, it is important that the flooring and underlay are stored on site at the same temperature as the areas to be installed.
MuteMat LVT 650 - 1.6 must be bonded to the subfloor. It is not essential to commence installation in the centre of the room; it is generally more practical to commence along the longest wall running the rolls in parallel. Wherever possible the product should be installed so that the joints run with the direction of the main light in the installation area rather than against it. Ideally this will also be at 900 to the finished floor so that the chance of coinciding joints is minimised. The product should be dry laid into workable areas and cut at least 50mm over the length required and allowed to relax for the acclimatisation period as advised above. After acclimatisation the underlay should then be cut using a utility knife and straight edge and a gap of around 3mm should be left around the perimeter to allow for any expansion. The MuteMat LVT 650 -1.6 should not be in direct contact with any wall, column or skirting board that has not been isolated using a perimeter isolation strip. The product should be adhered to the subfloor using a recommended adhesive (please contact us for information) strictly in accordance with the installation instructions of the adhesive manufacturer. It is particularly important to refer to the adhesive manufacturer’s advice in respect of trowel sizes, application rates/coverages and open times. Only spread enough adhesive to cover a workable area, and after the required open time lay the product into the adhesive and smooth out from the centre using a carpet glider or hand roller to ensure that the product is fully into the adhesive and all air bubbles are released. The MuteMat LVT 650 - 1.6 should then be fully rolled into the adhesive using a 68kg articulated flooring roller to ensure full adhesion along the entire length and width of the product. All edges should be butt jointed ensuring that all seams and joints are smooth without any voids but not too tight. Open seams with any gaps will “telegraph” through most LVTs, so it is very important that the underlayment work is as smooth and well seamed as possible.
Once the MuteMat LVT 650 - 1.6 is fully bonded to the subfloor, this time will depend on the adhesive used but usually after 24 hours, the LVT can be installed. MuteMat LVT 650 - 1.6 should be used with glued down LVT products of a minimum thickness of 2mm so that issues of “telegraphing” through are minimised. To provide noise improvement the product has to have a level of resilience to absorb impact energy and as such adds a degree of softness to the overall floor. This must be born in mind for areas where critical lateral lighting may be present, also please seek advice for installation areas where there may be equipment with extreme point loading. The LVT should be installed following the instructions of the LVT manufacturer using a suitable approved adhesive with correct notched trowel size. MuteMat LVT 650 - 1.6 has limited porosity so some wet set adhesives may take longer to go off. Ideally the LVT should be installed at 900 to the MuteMat LVT 650 - 1.6 so that the chance of coinciding joints is minimised. It is important to leave a small gap so that the finished floor does not come into contact with any part of the perimeter to avoid flanking problems. The gap should be filled with acoustic sealant.
These instructions are not exhaustive and may not be suitable for all LVT floor coverings, if in doubt please contact a member of the technical team on 01937 588 226 or email [email protected]
Soundproofing products act as a barrier to decrease sound leaving or entering a room or workspace. Sound absorbers absorb the sound within a room and assist to reduce room reverberation etc. Absorbers do not prevent the sound leaving the space but will reduce it. If you are wanting to soundproof a room you would have to buy soundproofing products. It may also be worthwhile to think about some absorbers inside the room to help reduce the sound before it hits the soundproofing.
A sound barrier is a sound blocker and usually includes insulation with a high mass, which then reduces the amount of sound that can pass through it. A standard domestic door is a good example of a noise barrier when it is closed as it reduces the sound of external noise. Sound waves flow like water and air so it is impracticable to use a sound barrier such as a fence or screen to stop noise but they are effective when used to reduce noise immediately on the other side of them. From distances farther away the noise reduction will be less efficient.
