Acoustic Performance

Architectural acoustics are essential in ensuring sounds are transmitted clearly and effectively – SIPCO SIPs offer excellent acoustic performance.

Architectural acoustics play a pivotal role in ensuring sounds are transmitted clearly and effectively. SIPCO SIPs (Structural Insulated Panels) are renowned for their excellent acoustic performance, which is crucial in both residential and commercial buildings. The sound resistance levels of SIPs can vary, depending on the build-up of the system, the external finish applied, and the thickness of the insulating foam core. At SIPCO, we pride ourselves on offering bespoke advice to select the best system components to meet your acoustic goals.

High Levels of Acoustic Performance

Our SIPs conform to the rigorous standards set by BS EN ISO 140-3:1995 Acoustics — Measurement of sound insulation in buildings and of building elements. This standard outlines the laboratory measurement of airborne sound insulation of building elements, ensuring high levels of acoustic performance.

Although there are no specific requirements for the sound insulation performance of external walls within national Building Regulations, considerations are made when significant external noise sources are present, such as a main road, rail line, or airport. Under such circumstances, the levels of prevailing ambient noise dictate the ultimate performance of external facades. Typically, window units and any trickle ventilators become the dominant points of noise ingress into a building.

Improving the sound insulation performance of a building, whether internal or external walls, often involves the use of acoustic-rated plasterboard in multiple layers. This technique is standard practice when the aim is to enhance sound insulation. For projects facing unique acoustic challenges, SIPCO recommends consulting with an acoustic consultant. Such professionals can assist in determining the specific specifications and performance requirements to meet or exceed Building Regulations.

Building Regulations and Acoustic Performance

Building Regulations across the UK specify airborne sound insulation performance targets for internal walls, which are dependent on the property’s location. These targets are expressed as Airborne Sound Reduction (Rw) based on laboratory test data.

It’s important to note that these walls are not subject to pre-completion sound insulation testing on-site. However, for separating/party/compartment walls and floors, the regulations vary but consistently specify an airborne sound insulation performance target. These criteria are crucial for pre-completion testing performance and are strictly tested on-site to ensure compliance.

SIPCO offers extensive guidance and technical support to navigate the Building Regulations, helping you achieve your acoustic performance objectives. Our expertise extends to the requirements for intermediate, separating, party, and compartment floors, where we provide invaluable assistance to meet testing requirements.
