Noise transmission between apartments is one of the most common quality-of-life complaints among residents in Malta and Gozo. If you can hear your neighbour’s television through the wall, if footsteps from the flat above echo through your ceiling, or if conversations in the next room carry clearly through a thin partition, you are not alone. The dense, closely built nature of Maltese residential construction — particularly in terraced houses, apartment blocks, and converted townhouses — means that sound transfer is a widespread issue. The good news is that gypsum board systems, when properly specified and installed, offer one of the most effective and practical solutions for reducing noise between apartments and within buildings.
To understand why noise is such a problem in many Maltese apartments, it helps to understand how sound travels. Sound moves through both air and solid materials. Airborne sound — voices, music, television — travels through gaps, thin walls, and lightweight structures. Impact sound — footsteps, doors closing, objects dropping — travels through the building’s structure itself, vibrating through concrete slabs and block walls.
Many older properties in Malta and Gozo were built with single-skin block walls between apartments. While these walls provide some degree of sound reduction, they often fall short of what most people consider acceptable for comfortable living, particularly in an era of home entertainment systems and open-plan living. Even in newer developments, where building standards have improved, the standard concrete and block construction can still allow more sound transfer than residents expect.
The problem is compounded by the typical Maltese building layout. Terraced houses share party walls along their entire length. Apartment blocks stack units directly above and below each other. In older villages and urban cores, buildings are built right up against each other with minimal separation. All of these factors create multiple pathways for sound to travel between living spaces.
A gypsum partition wall designed for acoustic performance works on a fundamentally different principle than a solid block wall. Instead of relying on sheer mass to block sound (which is the approach of a heavy block wall), an acoustic gypsum partition uses a combination of mass, decoupling, and absorption to achieve superior sound reduction.
The basic structure consists of a metal stud framework with gypsum boards fixed to each side. Crucially, the two layers of gypsum board are not rigidly connected to each other through the studs in the way that both faces of a block wall are connected through the block itself. The metal studs provide a degree of mechanical separation, and this separation is what reduces the direct transmission of vibration from one side of the wall to the other.
Within the cavity between the two gypsum faces, acoustic insulation material — typically mineral wool or rock wool — is installed. This insulation absorbs sound energy as it passes through the cavity, converting it to a tiny amount of heat rather than allowing it to reach the other side. The combination of mass from the gypsum boards, decoupling from the stud system, and absorption from the cavity insulation creates a wall system that can significantly outperform a standard single-skin block wall in terms of sound reduction.
For even higher acoustic performance, the system can be enhanced. Using double layers of gypsum board on each side increases the mass. Using resilient channels or acoustic mounting clips between the studs and the boards further decouples the two faces. Sealing all edges, joints, and service penetrations with acoustic sealant prevents sound from leaking through gaps — because even a small gap can dramatically reduce the effectiveness of an otherwise well-built acoustic wall.
Not all gypsum boards offer the same acoustic performance. Standard gypsum boards provide a baseline level of sound reduction that is adequate for many internal partitions where acoustic privacy is not critical, such as a partition between a bedroom and a hallway within the same apartment.
For walls between separate apartments, or in situations where higher sound reduction is needed, specialised acoustic gypsum boards are available. These boards are denser and heavier than standard boards, which increases their ability to block airborne sound. Some acoustic boards also incorporate a viscoelastic damping layer that converts sound vibrations into heat, further reducing transmission.
Moisture-resistant acoustic boards are also available for situations where sound reduction is needed in humid environments, such as bathrooms that share a wall with a neighbour’s living space. Our team at Xmun Projects advises on the correct board specification for each application, balancing acoustic performance with practical requirements and budget.
Gypsum acoustic partitions do not have to work alone. In many cases, the best results come from combining gypsum systems with other soundproofing approaches. For example, if the primary noise problem is impact sound from the floor above — footsteps, chairs scraping, children running — then the most effective solution may involve acoustic treatment of the floor above rather than, or in addition to, the ceiling below. Floating floor systems, acoustic underlay beneath tiles or laminate, and resilient matting can all reduce impact sound at its source.
For ceiling noise, a suspended gypsum ceiling with acoustic insulation in the cavity above it can meaningfully reduce both airborne and impact sound from the apartment above. Using resilient mounting systems for the ceiling framework further improves performance by preventing direct vibration transfer from the concrete slab to the gypsum ceiling surface.
In some situations, applying an independent gypsum lining to an existing block party wall — rather than building a full new partition — is the most practical approach. This involves fixing a metal framework to the existing wall (or, for better acoustic performance, standing it slightly away from the wall), filling the cavity with acoustic insulation, and cladding the room-facing side with one or two layers of gypsum board. This approach sacrifices a small amount of room width but can dramatically improve the sound insulation of the shared wall.
One of the great advantages of gypsum acoustic systems is that they work equally well in new construction and in existing buildings. In a new build, acoustic partitions can be designed into the plans from the start, ensuring that the correct stud sizes, board specifications, and insulation types are used throughout. This is particularly relevant for developers building apartment blocks in Malta and Gozo, where buyers increasingly expect — and deserve — a reasonable level of acoustic privacy between units.
In existing properties, gypsum acoustic solutions can be retrofitted without the need for major structural work. Adding an independent gypsum lining to a shared wall, installing a suspended acoustic ceiling, or replacing a thin internal partition with a properly insulated gypsum system are all projects that can be completed relatively quickly with minimal disruption. The work is clean compared to block construction, and the results are immediate — once the gypsum is installed and finished, you will notice the difference the same day.
At Xmun Projects, we have carried out acoustic gypsum work in apartments, terraced houses, offices, and commercial spaces across Gozo and Malta.
