It’s not just heat that finds it tough to get through rock. ROCKWOOL stone wool products are amongst the most effective acoustic insulation solutions used in construction.
ROCKWOOL Stone Wool can be used in three different ways to help reduce sound transfer
- Light and mid-density products work to provide airborne sound absorption - these can dramatically improve acoustic performance by 'soaking up' sound. Sound energy causes mechanical movement of the fibres, and fluid friction as trapped air molecules move back and forth inside the small pores - these processes harmlessly dissipate sound energy as tiny amounts of heat.
- Heavier structural products can act as a resilient layer in floating floor constructions to absorb noise from footsteps and other impacts, by damping vibrations before they're transmitted through the rest of the structure - which would otherwise be re-radiated as noise into the space below.
- Our heaviest products can be used to add mass to a building element, improving sound insulation. The heavier a building element is, the more difficult it is for sound to pass through it. ROCKWOOL HARDROCK® Multi-Fix DD can provide excellent sound performance against both airborne noise and rain noise, and is an ideal solution for high end projects with demanding acoustic requirements such as schools and cinema complexes. Ablative Coated Batt is a high density slab that in addition to its fire performance, will also reinstate acoustic performance where voids have been created in partitions to allow for the passage of building services.
The natural sound barrier
It’s the open, porous structure of stone wool that makes it highly efficient in protecting against noise pollution. In ceilings, noise screens, around noisy machines, in walls, roofs and floors and even underneath rail tracks, ROCKWOOL insulation acts as a natural and effective sound barrier. ROCKWOOL insulation is the number one acoustic solution when soundproofing buildings.

The challenge The design of the O2 arena’s roof had to incorporate state-of-the-art acoustic engineering to eliminate virtually all nuisance ambient noise (bass thumping) outside the arena while ensuring fantastic acoustics inside the structure.
In December 2007, RCT Homes Ltd became Wales’s largest social landlord after taking over the ownership and management of nearly 11,000 homes from Rhondda Cynon Taf County Borough Council. A not-for-profit organisation, RCT Homes provides high quality housing and manages housing services for more than 60 housing estates and 27 sheltered housing schemes.
Stopsley High School is a mixed Comprehensive and Community College that is located in the northern suburb of Luton. Achieving ‘Specialist Sports College’ status in 2002, the school educates children from 11-16 years old. In 2013, the school received funding from the Government, via the Priority School Building Programme (PSBP), which aims to address the needs of schools most in need of urgent repair.
REECH (Renewables and Energy Efficiency in Community Housing) is a European Regional Development Fund (ERDF) funded project aimed at improving energy efficiency in some of the most deprived communities in Liverpool. Social housing provider, One Vision Housing, accessed ERDF funding to help fund the improvement of the Hornby Flats Estate development in Litherland.
Aldgate Tower is a brand new, state-of-the-art office development, the first phase of a wider regeneration of the Aldgate area in London.
A tightly grouped housing development, less than 500m from the south bank of the Dee estuary, Dee Cottages is an early example of corporate involvement in housing design directly associated with the arrival of the Courtaulds company during the closing years of the First World War.
The task was to extend the life of three 1960s residential tower blocks by significantly improving the insulation, thereby increasing thermal comfort and making the flats more economical for residents to heat.
