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 through 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. However, some frequencies are below the range our products can effectively control e.g. traffic rumble.
For walls and partitions Rockwool semi-rigid 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. For floors, Rockfloor is an insulation board for both thermal and acoustic performance in a variety of buildings. Consult our new SoundPro range for solutions to typical noise problems.
We are building a timber framed house can you tell me the thickness of insulation required to achieve the building regulations in walls and floors?
The building regulations state that you need to achieve a u value of 0.35 W/m2K for walls, you can be achieved by using 120mm of Rockwool Flexi between the timber stud work in a typical timber framed house to achieve the 0.35 W/m2K U value.
To achieve the acoustic requirements between timber stud walls you will require a layer of 10 kgs/m2 plaster board either side of 68 x38 stud work and 50mm Rockwool Flexi between. To achieve the acoustic requirements between floors you will require a 15kg/m2 t&g chipboard flooring 100mm Rockwool Flexi between the joists and a layer of 10 kg/m2 plaster board to the under side.
When installing recessed lighting within a ceiling are there any precautions required if there is already insulation between the joists?
When installing downlighters within a ceiling you should have acoustic/fire covers, or maintain a void over the top of them.
How do I reduce noise nuisance from pipes?
Rockwool Techwrap2 and Techtube are specially designed to provide the highest standard of noise control to circular and rectangular ductwork, rainwater, soil-vent, service and process pipes.
What is the dB rating can I achieve with Rockwool insulation?
The dB rating (acoustic performance) of any Rockwool product is determined by the total construction. Many Rockwool products have been tested in a number of standard constructions, details of which are explained for each application separately inside the product library and contained within the Soundpro brochure.
What acoustic qualities does Rockwool insulation have?
Rockwool is used by specialists in many demanding acoustic applications.
Rockwool stone wool 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. Hear the difference
By fully filling a masonry cavity wall, what acoustic improvement can I expect?
Fully filling a cavity with insulation is designed primarily as a thermal solution. We would not expect any significant acoustic improvement.
I am insulating a music room. What products do you recommend?
We would suggest lining the walls with a tissue faced slab such as RW5 (Rockwool semi-rigid slabs). The insulation product would then need to be protected from damage. Typically, this would be achieved with a suitable covering such as a suitable perforated metal or a suitable external finish. Please take advice from an acoustic consultant.
