Wall soundproofing in Ireland is one of the most searched acoustic topics online, and for good reason. Noise complaints in homes and apartments have grown steadily as more people work from home, live in higher-density housing, and expect more from their living spaces. The good news is that wall soundproofing does not have to mean a full renovation. The right products and approach can make a big difference quickly and affordably.
This guide covers why walls let sound through, what actually works, and the best products available in Ireland right now.
Why Wall Soundproofing in Ireland Matters
Most walls in Irish homes are not built with noise in mind. Standard stud walls with a single layer of plasterboard on each side offer very little resistance to sound. Older solid walls are better but still fall short of modern acoustic standards.
Sound travels in two ways through a wall. Airborne sound is noise that travels through the air, like voices, music, or a TV. Impact sound is vibration that travels through the structure itself, like footsteps or a door slamming.
A good wall soundproofing solution needs to address both. Most standard insulation only deals with one.
What Does Not Work
Before covering the right approach, it is worth being clear about what people waste money on.
Thin foam tiles or egg cartons. These absorb echo inside a room. They do not block sound from passing through a wall. You will still hear everything next door.
A single extra layer of plasterboard. This adds some mass but very little on its own. Without a high-density barrier behind it, the improvement is barely noticeable.
Acoustic paint. This is largely a myth. Paint cannot add the mass required to meaningfully block sound.
The issue with wall soundproofing is always mass. Sound needs a dense, heavy barrier to stop it. The thicker and heavier the barrier, the less sound gets through.
How to Soundproof a Wall Properly
The most effective wall soundproofing method is a layered system. Think of it as a sandwich. Each layer adds mass, damping, or decoupling. Together they stop far more sound than any single product on its own.
Here is the approach that works:
Step 1: Add a high-density barrier. This is the most important step. A heavy acoustic membrane installed behind your plasterboard adds the mass needed to block airborne noise. This is where AM EcoVinyl Mass Loaded Vinyl comes in. It is thin, flexible, and adds 5kg or 10kg per square metre of mass to your wall without significantly increasing thickness.
Step 2: Use a self-adhesive membrane for fast application. If you want maximum density with minimal installation effort, Tecsound S 100 is a professional-grade option. It weighs 10kg per square metre, is 5.5mm thick, and peels and sticks directly onto your existing wall surface. It delivers an Rw of 32dB, which is a serious level of airborne sound insulation in a single layer.
Step 3: Seal every gap. Sound finds the weakest point. Around sockets, light switches, skirting boards, and where the wall meets the ceiling or floor, use a non-hardening acoustic sealant. Even a tiny gap will let significant noise through.
Step 4: Finish with a new layer of plasterboard. Once your barrier layer is in place, board over it. The combination of the high-density membrane and the plasterboard gives you the mass and rigidity needed to block both airborne and some impact noise.
Which Wall Soundproofing Product Is Right for You?
The right choice depends on your situation.
New build or full renovation. Use MLV installed between stud framing and plasterboard. The AM EcoVinyl roll covers 5 square metres and is the most cost-effective option for larger jobs. It is also 100% recycled and recyclable, qualifying for LEED and BREEAM green building credits.
Retrofit or rental property. If you cannot open up the wall, Tecsound S 100 sticks directly to the existing surface. You can then dot-and-dab a new layer of plasterboard over the top. Minimum disruption, maximum result.
Apartment or shared wall. A shared wall between two apartments is the hardest to treat because you only have access to your side. The best approach is to add as much mass as possible using MLV or Tecsound plus a resilient channel system to decouple the new plasterboard from the structure.
Want a Wall That Looks Good Too?
Most wall soundproofing products are hidden behind plasterboard. But if you want the finished wall to do double duty, the AM MDF Veneer Acoustic Wall Panel is worth considering.
It is a 2400mm x 600mm decorative panel with a pre-finished timber veneer surface. No painting or treating needed. It fixes directly to the wall with screws and adhesive and is ready to look at the moment it goes up.
It works by absorbing echo and ambient sound inside the room, reducing that hollow, reverberant quality you get in rooms with hard floors and bare walls. It will not stop your neighbour’s TV on its own, but used alongside a barrier layer like MLV or Tecsound, it completes the job. The barrier stops the noise getting in. The panel controls how the room sounds once it is in.
It is a popular choice for home offices, living rooms, home cinemas, and any space where acoustics and aesthetics both matter.
How Much Wall Soundproofing Do You Actually Need?
The World Health Organisation recommends indoor noise levels below 35dB for restful sleep. Most Irish party walls without treatment sit well above this when a neighbour has a TV on or is having a conversation.
A well-built wall with a high-density membrane layer can achieve an STC or Rw rating of 45 to 55dB. That is enough to reduce a loud conversation to barely audible. Adding decoupling and a second layer can push this higher.
You do not need a perfect result. You just need a meaningful improvement.
