Addressing Flanking Noise First
Before diving into party wall soundproofing, it’s essential to understand and mitigate flanking noise. Flanking noise refers to the sound that travels around or through the wall via other paths, such as ceilings, floors, or adjacent structures. If not addressed, it can significantly undermine your soundproofing efforts.
Soundproofing Adjacent Floors
When dealing with flanking noise, it’s crucial to soundproof adjacent floors. If there’s another habitable room above the ceiling, consider installing 100mm of acoustic mineral wool between the joists, adjacent to the separating wall. This can be achieved by lifting a few floorboards. For top-floor rooms, ensure that there’s adequate loft insulation, meeting current thermal insulation requirements.
Ceiling Soundproofing Techniques
Ceiling treatment is vital for comprehensive party wall soundproofing, as sound can travel over the walls through ceiling voids. For effective ceiling soundproofing, consider adding layers of acoustic plasterboard to the existing ceiling or using resilient ceiling bars to decouple the ceiling surface from the structure. For period properties with lath and plaster ceilings, handle with care to avoid damage. By combining floor and ceiling treatments with wall soundproofing, you create a comprehensive sound barrier that addresses all potential noise paths.
Thin Soundproofing Solutions for Party Walls
To tackle noise issues through party walls, consider implementing a thin soundproofing solution that is both effective and unobtrusive. These solutions are designed to minimise disturbance without requiring significant renovations or extensive construction.
Using Acousticel M20AD
The Acousticel M20AD insulation is a highly effective material for soundproofing party walls due to its ease of installation and thin profile. It can be easily cut and bonded to the wall using Sta-Stuk aerosol contact adhesive. When combined with two layers of 15mm acoustic plasterboard, it provides a robust soundproofing solution.
Acousticel M20AD is a versatile solution that can be used in various settings, offering a reliable method to enhance soundproofing without compromising on space.
Acoustic Plasterboard Installation
Acoustic plasterboard is a denser alternative to standard plasterboard, offering enhanced sound-blocking properties. To install, measure and cut the acoustic plasterboard to size, then fix it to the wall, ensuring staggered joints between the two layers to maximise soundproofing performance.
The installation process requires careful handling due to the heavier weight of acoustic plasterboard compared to standard plasterboard. It is essential to use appropriate fixings and consider additional support where necessary.
By combining Acousticel M20AD with acoustic plasterboard, you achieve a thin yet effective soundproofing solution that adds approximately 50mm to the wall thickness, making it suitable for most rooms.
How to Soundproof Party Wall DIY: Thick Solution Method
For persistent or severe noise problems, a more substantial soundproofing approach is often necessary. The thick solution method involves constructing a robust soundproofing system that can effectively minimise noise transmission through party walls.
Installing Timber Studs and Acoustic Mineral Wool
The first step in the thick solution method is to install timber studs within the party wall cavity. This creates a framework for the soundproofing materials. Acoustic mineral wool, such as that available in the UK, is then placed between the studs to absorb sound energy and reduce reverberation.
The correct installation of acoustic mineral wool is crucial for its effectiveness. Ensure it is cut to fit snugly between the studs, filling the entire cavity without compression.
Resilient Bars and Plasterboard Application
To further enhance the soundproofing performance, resilient bars are screwed horizontally across the timber studs. Two layers of acoustic plasterboard are then applied, with the first layer screwed to the resilient bars. To maximise sound reduction, a high-mass sound barrier mat, such as SBM5 Sound Barrier Mat, is sandwiched between the two plasterboard layers.
The use of resilient bars is critical as they decouple the plasterboard from the stud frame, creating a floating wall surface that minimises vibration transfer. Proper spacing and fixing methods are essential for optimal performance.
Dealing with Special Challenges
You may face specific obstacles when attempting to soundproof a party wall, particularly if it contains a chimney breast or electrical outlets. Effective soundproofing requires addressing these challenges directly to achieve optimal results.
Soundproofing Walls with Chimney Breasts
Soundproofing a wall that contains a chimney breast is never as effective as it would be without one. To improve soundproofing in such cases, start by inserting a thin black bin bag filled with fibreglass loft insulation into the fireplace, then brick up the fireplace flush with the outside of the chimney breast. This simple step can significantly enhance the overall soundproofing performance of the wall.
Addressing Electrical Outlets and Fixtures
Electrical outlets, light switches, and other wall fixtures can create weak points in your soundproofing system, allowing noise to pass through. To mitigate this, consider extending electrical boxes to accommodate additional wall thickness, sealing around fixtures with acoustic sealant, or repositioning outlets to avoid penetrating the soundproofing layer. Back-to-back electrical outlets on party walls are particularly problematic and may require special treatment, such as using acoustic putty pads. Ensuring these details are properly addressed is crucial for achieving optimal soundproofing performance in your space.
Advanced Soundproofing Techniques
For those looking to take their soundproofing efforts to the next level, advanced techniques can provide the solution needed to tackle even the toughest noise challenges. Advanced soundproofing involves employing a combination of materials and methods tailored to specific noise issues.
Combining Multiple Layers for Maximum Effect
To maximise soundproofing effectiveness, combining multiple layers of different materials is often the most effective strategy. This approach allows you to leverage the unique benefits of various soundproofing elements, such as high mass materials and acoustic mineral wool, to create a robust barrier against noise.
Sound Barrier Mat Applications
Sound barrier mats, such as the SBM5, are specialised high-mass products designed to enhance soundproofing. These mats are particularly effective when used between layers of plasterboard or as part of a multi-layer soundproofing system. Despite their thin profile, typically ranging from 2-5mm, they provide significant mass that helps block sound waves, particularly in the mid to high-frequency range.
When installing sound barrier mats, it’s crucial to follow proper cutting, handling, and fixing procedures. Using appropriate adhesives and ensuring correct decoupling between layers can significantly enhance the overall soundproofing performance of your wall construction.
Sound barrier mats are not only effective but also an environmentally friendly option, as many are made from recycled materials. Their ability to offer an excellent balance of performance and space efficiency makes them a valuable component in most DIY soundproofing projects.
