Description
Noisestop F7 Plus is a premium acoustic underlay. It provides excellent sound reduction against impact and airborne sounds, including footfall and conversation. The 15mm thick soundproof mat has minimal impact on the floor buildup. Acoustic underlays are a popular choice in domestic situations due to the ease of installation the mats are easy to cut and loose laid over the floor. Noisestop F7 Plus is a triple layered acoustic mat combining acoustic grade closed cell foam sandwiched between high density mass-loaded vinyl membranes. Noisestop F7 Plus is suitable for use on its own or as part of a complete soundproof floor system compliant with Part E Regulations.

Noisestop F7 Plus Benefits
System Performance
Noisestop F7 Plus will offer a significant reduction over standard floor constructions. When used as part of a flooring system for Building Regulations, it will ensure Part E compliance for new builds and conversions.
According to the figures, the Noisestop F7 Plus effectively reduces airborne and impact sounds by reducing 53dB for airborne sounds and 50dB for impact sounds. This solution meets Part E compliance standards and effectively blocks clear airborne sounds and heavy impact noises.
Performance data for the Noisestop F7 Plus used over a timber floor. The higher the figure for airborne, the better the performance. The lower the figure for impact, the better the performance.
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.
| Airborne DnT,w (dB) | Impact L’nT,w (dB) |
| 53 | 50 |
Floor Finishes
Carpet as the floor finish
Noisestop acoustic underlays can be used directly below the carpet. When installing the soundproof underlay, you should consider using the perimeter edging strip to ensure the gripper rods are at the same height as the carpet. The gripper rods and the perimeter edging should be nailed to the floor using a 30mm nail.
Hard floor finishes less than 15mm
Hard floor finishes, including laminate, engineered, and tiles, should use a resilient layer between the soundproofing and the floor finish. We recommend a sheet material such as 6mm ply or interlocking MDF. The layers are secured using a floor-grade adhesive such as Isobond floor adhesive. To prevent potential flanking sound from transmitting from the floor to the walls, isolate the flooring using isolation tape fixed to the wall.
Hard floor finishes of more than 15mm
Floor finishes over 15mm can be installed directly on the soundproof mats. Secure the flooring using the Isobond adhesive. To prevent potential flanking sound from transmitting from the floor to the walls, isolate the flooring using isolation tape fixed to the wall.
Fitting Noisestop F7 Plus
- Laid directly over the existing sub-floor
- Loose laid no requirement to bond to the floor. Part E requires bonding for new builds and conversions
- Butt the edges together
- Reduce movement with High Tack Tape along the joins
- Cut to size using a sharp knife or a fine toothsaw

Floor Soundproofing
Make sure you are getting the right soundproofing for your needs. Understanding the most common types of noise and how to stop them will help you decide the right solution.
Different Types of Sound
- Airborne sounds – Conversation, TV noise and radios are examples of airborne sound. The best way to stop airborne sounds is to add mass/density to the walls or ceilings.
- Impact/vibration sounds – Footfall and moving furniture across a floor are examples of impact sounds. The best way to reduce these sounds is to create separation.
In summary, the best way to reduce airborne sounds is by increasing the mass of the area you would like to soundproof. Reducing impact/vibration sounds is achieved by creating separation within the structure.
Reducing Impact and Airborne Sounds
By following some of these steps, you will ensure you get the best level of soundproofing for your room.
- Mass/Density – Increasing the mass and density of the area you are soundproofing will block airborne sounds from transferring between rooms. You will increase the mass of walls and ceilings using materials such as soundproof panels or high-density acoustic insulation slabs.
- Separation – Incorporating separation within the structure will reduce vibration and impact sounds transferring between rooms. Achieve separation by building independent stud walls and ceilings. If you don’t have the space in the room, you can use acoustic clips and resilient channels to decouple the wall and ceiling.
- Absorption – Use materials that are going to absorb sounds. Acoustic insulation is suitable for sound absorption as it converts the sound waves into heat as it passes through the insulation. Dense mass loaded barriers will also dampen and absorb sound.
