Creating buildings that are safe and sound

Acoustics is a fundamental element in any building design. Whether it’s to create a sound learning environment for education, a calm space in healthcare, a peaceful home to live in, or to prevent building operations causing a disturbance.

Minimising sound transfer and controlling reverberation are not only key for regulation compliance, they are also central to delivering buildings that are fit for purpose.

This resource hub brings all our specialist acoustics resources into a single place, helping you to better understand the role of building acoustics – and how ROCKWOOL non-combustible stone wool insulation can be used to renovate or construct buildings that are safe as well as sound.

The ROCKWOOL Red Book

Use the ROCKWOOL Red Book to further develop your understanding of acoustic principles in building design and navigating the relevant acoustic building regulations in England, Scotland, Ireland and Wales. Backed by acoustic test data, use the ROCKWOOL Red Book to determine the ROCKWOOL insulation that will deliver the sound reduction and control that you need.

ROCKWOOL Case Studies

Frequently Asked Acoustic Questions

General Questions

What acoustic qualities does ROCKWOOL insulation have?

ROCKWOOL insulation is used by specialists in many demanding acoustic applications. ROCKWOOL stone wool insulation works in two distinct ways to reduce noise, either by impeding the transmission of sound through an element of the structure or by absorption of sound at the surface.

What dB rating can I achieve with ROCKWOOL insulation?

The dB rating (acoustic performance) of any ROCKWOOL product is determined by the total construction. The acoustic performance of a construction will be dependent upon the sound path, the mass and absorbative qualities of the products used within the construction. ROCKWOOL products have been tested in a number of standard constructions - to find out more, speak to our technical solutions team.

How do I reduce noise from next door?

We have a range of tested solutions for walls, floors and flanking sound transmission to meet or exceed the current acoustic requirements for Approved Document Part E.

Can I use my Sound Insulation slab for a thermal application or do I need to buy the Thermal slab?

Yes, ROCKWOOL insulation has natural inherent properties for thermal, fire and sound which is present in all products. Therefore, if you are using a sound insulation slab, you will automatically get a thermal and fire benefit.  The only exception is for masonry cavity walls which must use the specific performance tested product which is ROCKWOOL cavity for full fill applications.

I am insulating a music room. What products do you recommend?

We would suggest lining the walls with a tissue faced slab such as RW3 or RW4. The insulation product would then need to be protected from damage. Typically, this would be achieved by installing a perforated sheet. 

How do I reduce noise from next door?

That depends on what kind of wall or partition needs insulating acoustically. Acoustic improvement can be complicated, but there are several ROCKWOOL products and systems which can help reduce interference sounds though structures.  Impact, reflective and penetrating sounds transmit in different ways and behave differently in varying frequency ranges. The principle on which ROCKWOOL acts successfully as an acoustic insulant is by diffusing and absorbing the sound waves. 

For walls and partitions ROCKWOOL semi-rigid slabs (RW Slab range), FLEXI or Thermal and Sound Slabs will provide effective reductions in decibel levels (dB) These can be fixed against walls, or in timber frames separated from the main structures to avoid the possibility of sound bridging. 

How do I reduce noise from downstairs?

Acoustic improvement can be complicated, but there are several ROCKWOOL products and systems which can help reduce interference sounds though structures. Impact, reflective and penetrating sounds transmit in different ways and behave differently in varying frequency ranges. The principle on which ROCKWOOL acts successfully as an acoustic insulant is by diffusing and absorbing the sound waves. For floors, Acoustic ROCKFLOOR® is an insulation board for acoustic performance in a variety of buildings. 

Can ROCKWOOL help reduce noise transmitted through pipes and air conditioning systems, or from plant and machinery?

Yes, there are several products which can help. ROCKWOOL's proven combination of high acoustic porosity, acoustic frictional resistance and light weight makes it ideal for use in a wide range of demanding situations. Products to look for include Techwrap and TechtubeDuctwrap and ductslab and pre-formed pipe sections such as H&V sections.
