Floors
Acoustic Mineral Wool and Membrane
This installation is usually made when old floor planks are replaced with chipboards, mineral wool is then installed in between the joists then a structured deck is installed over the entire floor. The floor is not adjusted to anything due to the floating style that it follows.
Floors
Over Floor Soundplanc and Acoustic Mineral Wool
This installation process includes adjusting the mineral wool in between the joists and floorboards then the original floorboards are put back on and then sealed with an acoustic sealant. A thick plasterboard layer is mounted on the surface and coated with an acoustic silicone.
Floors
Under Floor Soundplanc and Acoustic Mineral Wool
This installation may not be as effective as the over-floor system; however, this system is used where there is no ability to increase the height of the flooring or if the client would like the original flooring to be exposed.
Floors
Under Floor Hanger System
This installation process is chosen when the client wants the original floorboards as the finishing layer. The original floorboards are removed, and the joists are fitted with mineral wool. The floorboards are then refitted to the flanges of a suspension hanger that is mounted on the joists..
Flooring
Acoustic Mineral Wool and Triple Barrier Matt
This system involved removing the original floor panels, adding mineral wool and then refitting the original panels back and sealing with acoustic silicone for extra absorption.
Floors
Acoustic Mineral Wool and Defender35
This installation process includes removing and replacing the old floor panels with new particle board. Mineral wool is filled in between the joists under the new panels.

| System | Typical improvement | Build-up depth | Best for |
|---|---|---|---|
| Acoustic underlay only | 13–18 dB impact | 5–15 mm | Budget fix under new finish |
| Acoustic deck | 17–20 dB impact | 18–30 mm | Good retrofit under hard floors |
| Resilient batten floor | 20–24 dB impact | 40–60 mm | Substantial impact-noise reduction |
| Floating floor (full) | up to 26 dB | 50–100 mm | Best performance — full decoupling |
Typical field-measured improvements on top of the existing construction. Exact numbers depend on the starting wall/floor and the install quality.

What is the difference between impact noise and airborne noise through floors?
Impact noise is mechanical — footsteps, dropped objects — and travels through the structure. Airborne noise is voices, TV, music — it travels through the air first, then makes the floor vibrate. They need different fixes: decoupling + resilient layers for impact, mass + damping for airborne.
Does a floating floor affect door heights?
Yes — a full floating floor typically raises the finished floor by 30–60 mm. Doors, skirting and thresholds all need adjustment. We factor this into the survey.
Will acoustic underlay alone pass a Part E test?
Usually not on its own. Underlay gives ~13–18 dB impact reduction, which helps but rarely delivers Part E’s 62 dB L’nT,w ceiling on a timber separating floor without other treatment.
How do I soundproof a floor without raising the floor height?
Options are limited: treat the ceiling below instead, or use a thin acoustic deck (18–25 mm) accepting reduced performance.
