Ensuring Serenity: Minimising Noise in Restored Staircases
In multi-level buildings and flats, staircases can often contribute to unwelcome noise, disrupting the tranquillity of the living space. Therefore, minimising this noise is essential for fostering a peaceful environment. This comprehensive guide explores various methods and materials to achieve optimal soundproofing for staircases, aimed at ensuring a quieter and more comfortable space for residents.
Compliance with Regulations
A critical step in noise reduction involves adhering to the UK’s Approved Document E Resistance to the Passage of Sound regulations, which require sufficient soundproofing in staircases, walls, and landings. For new builds, the minimum airborne insulation is set at 45dB, with a maximum impact noise level of 62dB. For buildings undergoing a change of use, these values adjust to 43dB for airborne insulation and 64dB for impact noise. Compliance with these standards is not only a legal requirement but also ensures that the living environment is protected against undue noise disturbances.
Soundproofing Techniques
Understair Soundproofing
The underside of the stairs can be a significant pathway for noise transmission. Consider these practical approaches:
- Acoustic Plasterboard: Affix acoustic plasterboard directly beneath the staircase for an immediate layer of soundproofing.
- Timber Studs and Acoustic Mineral Wool: Enhance this setup by attaching timber studs filled with acoustic mineral wool to absorb impact noise.
- Double Layer of Plasterboard: Finish with a double layer of 15mm acoustic plasterboard, ensuring a robust shield against noise escape.
Stair Treads and Risers
The materials and methods used on stair treads and risers greatly impact the level of noise they produce:
- Carpeted Treads and Cushioned Underlay: Consider using carpeted treads with a cushioned underlay to soften each step, significantly reducing impact noise. Solid wood is preferable as it dampens sound more effectively than hollow-core materials.
- Acoustic Underlay: Apply acoustic underlay, such as MuteMat 2, directly to the treads. This underlay, made from closed cell foam, is designed to absorb impact noise efficiently at its source.
- Support for Creaking Stairs: To address creaking issues, insert triangular wedges between the tread and riser, securing them with strong wood glue and screws for enhanced stability and noise reduction.
Wall Soundproofing
Walls adjacent to staircases can amplify both airborne and impact noise. Upgrading them can significantly contribute to soundproofing efforts:
- M20AD Recycled Rubber Soundproofing System: Use a 20mm M20AD recycled rubber system covered with acoustic plasterboard to add mass and improve sound insulation.
- Decoupling Walls: Implement isolation clips like the MuteClips system to reduce impact vibrations. This technique involves constructing a new soundproofing wall separate from the existing structure.
- Independent Wall Systems: Systems like ReductoClip™ Independent Wall System or SoundBoard 4™ can be employed to add mass and resilience, significantly reducing noise transmission.
Additional Measures
Beyond structural enhancements, simple measures can also mitigate noise:
- Lubrication of Stair Boards: Reduce squeaking in wooden stairs by applying powdered soapstone or talcum powder to the stair boards.
- Noise-Proofing Sealant: Fill any gaps or holes within the staircase using green glue noise-proofing sealant to prevent sound leakage.
- Sound-Absorbing Ceilings: Install Echosorption Plus sound-absorbing tiles on ceilings to reduce reverberation and airborne noise.

FAQs
Why is soundproofing staircases important in multi-level buildings?
Soundproofing staircases in multi-level buildings is essential because staircases can be a significant source of noise, affecting multiple apartments or floors. Proper soundproofing helps create a more peaceful living environment, minimising the transfer of noises such as footsteps and echoes that could disturb neighbours or other household members.
What factors should be considered when choosing materials for staircase soundproofing?
When selecting materials for soundproofing staircases, consider factors such as the existing construction of the staircase, the level of noise exposure, and the compatibility of materials with current regulations. Materials like acoustic plasterboard, mineral wool, and dense underlays are effective for soundproofing, offering different levels of mass and impact noise reduction.
Can soundproofing be a DIY project, or should professionals be involved?
While some soundproofing tasks, such as applying underlay or lubricating stair boards, can be accomplished as DIY projects, professional involvement is advisable for comprehensive solutions. Experts like those at Simons Staircase & Furniture Restoration are equipped to handle complex issues, ensuring the work meets safety standards and aesthetic goals.
By implementing these strategies and using appropriate materials, residents can significantly minimise noise from staircases, enhancing the comfort and quiet within their homes. Creating a serene living space benefits not only the direct occupants but also contributes positively to the broader community living environment.
