Acoustic Q&As

Does InstaGroup carry out independent acoustic testing for its systems? Where can I find results?

Independent acoustic tests on InstaGroup systems have been carried out on on-site at many of our installations.

These tests provide ‘real-world’ data rather than tests performed in perfect laboratory conditions. Results can be discussed with our experienced, customer-focused Technical Team.


How can I explain the importance of acoustics to clients?

Intrusive noise from neighbours can seriously affect quality of life and enjoyment at home.

Acoustic systems are designed to counter airborne noise such as voices, TVs, music, or slamming doors, and impact sounds heard through ceilings such as footfall on floors or children running. Acoustic floors, ceilings and walls can ensure peace and wellbeing for residents, and help to lower stress and potential conflict.


Where can I get acoustic design advice for my next project?

Our expert team is always happy to discuss your project needs and can offer advice on system design for both new builds and renovations or refurbs.

You can contact the acoustic Technical Team on 0118 932 8811


How do acoustic floors reduce impact sound reduction in concrete and timber separating floors to comply with Part E in building regulations?

Acoustic floors work by creating an isolating layer between the solid surface of the floor and the cause of the impact noise.

You can ask our expert acoustic Technical Team about building regulations and on-site acoustic test results by calling us 0118 932 8811


Does InstaGroup carry out acoustic testing for its systems on-site?

No — we do not carry out our own testing. All acoustic tests are carried out by independent UKAS-accredited testing companies.

Independent testing means you can trust that the acoustic results are not influenced by installers or Operations Directors.


How do I select the right acoustic flooring or acoustic materials for my project?

Please contact us for an initial chat so we can assess the viability of any proposed works. An open discussion is the best way to answer expectations of what can be achieved with our acoustic systems.

Whether you want to meet building regulations, or talk about how installation may impact the dwellings, our expert team can help.


What should architects consider when designing for good acoustics in residential dwellings?

Depending on the size of the project, we’d advise architects to carry out an acoustic test before doing any sound insulation works. This will help to establish how sound carries in the building from the start.

Finding out how good (or how bad) the sound insulation is in the building will help architects to prevent over-specification or under-specification.


What should architects consider when designing for good acoustics in mixed use buildings?

Architects need to consider every element of an existing building – walls, ceilings, windows, doors, floors – as these are all passages for sound.

New builds, which are effectively a blank canvas, offer the opportunity to design using mass and isolation products in the right combination to enhance the building’s acoustic performance.


How does InstaGroup’s acoustic flooring with EdB UFH system deliver maximum thermal efficiency?

The EdB system has foil backed panels to ensure the heating pipes stay in direct contact with the overlay board. This means the heat produced is driven upwards through the board to heat the living space.

Our underfloor heating design can achieve the heat outputs required at the lowest possible flow temperatures, which saves energy.

What is the advantage of InstaGroup’s ‘supply and fix’ service on construction projects?

Our experienced and trained installers and managers can be trusted to complete the works to high quality standards, while minimising interfaces with other trades. This saves time and money on the programme.

In addition we can install passive fire protection (Fire Batts) at the same time to answer the client’s safety strategy. This also saves the need for additional contractors to be involved in the installation.

InstaGroup is IFC accredited and can sign off its own passive fire protection work with no other trade required.


How can InstaGroup’s cradle and batten floor system help to reduce the environmental impact of construction?

No need for screed. Using our ‘dry’ system decreases the overall cement content of the slab, resulting in less embodied carbon in the construction.

No wet trades in the process also saves 12 litres of water per m2 compared to screed.

The lighter floor solution means that less structural steel/concrete is used.


Does switching from traditional in-situ concrete slabs to hollow core affect the acoustic performance of cradle and batten flooring?

We ran a series of independent acoustic tests for a client using our acoustic flooring on hollow core slabs.

Results proved that our dry acoustic floor systems can be installed on hollow core slabs and maintain the same high acoustic performance

This represents a real step forward in reducing environmental impact in construction, as our flooring can still deliver results well above building regulation acoustic levels when used on hollow core.

Why specify a lightweight acoustic flooring solution?

Using our lightweight C40 system with underfloor heating delivers a huge weight saving on the structural loading of the building.

Lower structural loadings results in a more slender design of the structural slabs, including less rebar than would be necessary with a standard screed.

This saves construction costs overall.


Can InstaGroup systems reduce the environmental impact of construction?

Many of our acoustic products, rubber cradles and components are manufactured from recycled rubber tyres and can be re-used.

We use sustainable sources of timber for our wooden battens, and our plastic battens are made from recycled UPVC windows.

Our products save on landfill too. Our recycled rubber crumb cradle and batten acoustic flooring prevents thousands of worn tyres from going to landfill every year.

InstaGroup’s ‘dry’ acoustic flooring system also helps to reduce water waste in construction. Our ‘no screed’ solution saved 12 litres of water per m2 in construction at Greenwich Peninsular Upper Riverside (GPUR).

What are the advantages of specifying a ‘no screed’ solution for acoustic flooring?

Our ‘no screed’ solution needs no drying time, which speeds up construction sequences. No wet trades are required, which also means less contractors on-site.

Less cement results in less embodied carbon in the construction. In addition, transportation and energy use are reduced, lowering carbon emissions.

No flushing out is needed, which helps to prevent water waste: our cradle and batten system saves around 12 litres of water per m2 against screed.

Our lightweight cradle and batten system also allows for easy floor height adjustments on-site.
