From buses to road sweepers, military to construction plant vehicles, vehicle noise is an issue in the commercial sector whether it is new developments in powertrain technology or hybridisation or electrification of vehicles.

While many of today’s trucks make 10 times less noise than those built over 40 years ago, road traffic noise remains the most widespread cause of environmental health problems across Europe.  According to the European Environment Agency, almost 70 million people are exposed to excessive long term average road noise levels (>55db), the level recognised to pose a serious risk to health by the World Health Organisation. 

A number of factors contribute to traffic noise, including the road surface and speed- dependent aerodynamic noise, but most urban traffic noise originates from the vehicles rather than the tyres.  The noise standards for commercial vehicles are particularly significant as they cause half of the road noise-burden across Europe.

Emissions pollution has driven changes in engine design such as hybrids and lean engines. However, high running temperatures can result in these engines being noisier.  Even electric vehicles have different noise characteristics which need controlling to gain market acceptance as they often have devices for energy storage that generate noise intermittently themselves .

Tackling noise at source

The vehicle engine is an understandable source of noise, and when you combine this with the powertrain, there are a large number of interlinked components that produce sound.  From rattles to sound pressure waves, these sounds include vibrations and ‘surface radiation’, which is the low-frequency sound produced by a surface as it pulsates, like a drum. The ‘mechanics’ of noise mean that as the sound level of any individual component is reduced, others become more noticeable – which means that all components must be worked on together to actually reduce engine (and vehicle) noise. This is also true for other noise producing vehicle elements. After reducing powertrain and exhaust sounds, other noises may become noticeable such as aerodynamic resistance or previously unnoticed tyre/road noise.

An additional benefit of reducing noise at source is that driver and passenger noise will be significantly improved. Further improvements to sound quality in-cab can be gained by addition of sound insulation and absorption behind or under the interior trim.

A quieter life

Having manufactured acoustic and fire insulation products for more than 40 years, SIDERISE offers a large range of tried-and-tested product enhancements specifically developed to the broad spectrum of requirements in the commercial vehicle sector.

Offering high insulation and absorption performance as well as fuel, oil and chemical resistance, these sound reduction and damping treatments have been expertly designed for the most challenging environments. 

At under 10kg/m3 density, SIDERISE foams are class leaders in weight- saving and by combining with other layers, excellent and targeted acoustic performance can be achieved at minimum thickness. These foam products can also be used in public service vehicles (PSVs) for thermal insulation leading to weight savings of the order of 100kg per vehicle, whilst improving thermal and acoustic performance. The addition of viscoelastic and polymeric heavy layers to these foams can produce high insulation and vibration damping performance.

Paul Handscomb of SIDERISE said, “Our noise control materials can be quickly installed on the production line or workshop and are independently tested to give our clients complete confidence in product performance.”

Fire protection

Recent awareness of the risks of vehicles in tunnels has also required materials with increased fire resistance and protection from ingress of potentially flammable fluids. Devices to burn off particulates and catalytic convertors generate significant heat in engine areas.  In addition, the increased containment by undertrays or close cladding to an engine requires higher temperature resistance materials. 

SIDERISE solutions will provide both integrated noise reduction performance of up to 20dB and are also compliant with Euro 6 legislation and tested to the toughest flammability regulations.  Able to withstand up to 800°C and 30 minutes fire protection, these non-combustible solutions offer exceptional thermal and fire safety performance.

With traffic noise affecting greater numbers of people and faced with tough regulations, the importance of taking a holistic approach to noise control on commercial vehicles has never been more apparent.  Through a wide range of independently tested noise control treatments, SIDERISE will be able to quickly and professionally reach the optimum solution, each and every time, and for the most challenging environments.

It is critical that modern buildings are designed to take into account all relevant design fire scenarios. Both passive and active systems need to be tested accordingly, and with little margin of safety for failure, specified and installed correctly.

Modern high-rise constructions may well push the design envelope and change the landscapes across our cities, but the consequences of fire spread in very tall buildings are extremely high. While acceptable levels of risk need to be proactively identified, it is critical that buildings be designed accordingly, taking into account all relevant design fire scenarios. Both passive and active systems need to be tested accordingly, and with little margin of safety for failure, they should be specified and installed correctly. It is ultimately a collective decision between a team of people - from the designer to the mechanical engineer, the fire risk assessor to the security specialist.

Fire should not be considered in isolation and in any design, all credible scenarios –whether evacuation, containment, fire resistance or suppression – must be considered as a part of a holistic safety strategy. While it is all very well having a theoretical or documented fire engineering strategy, the reality on sites is that there is often a disconnect between the design, specification and installation phases, which raises questions about the ultimate effectiveness of the strategy in the first place.

New fire code

In a bid to bring rules in line with global standards, new national fire regulations have recently come into effect in the UAE with the publication of the new Fire and Life Safety Code of Practice. This updated code is welcomed by the industry and takes a robust and comprehensive view on fire safety standards at all stages of construction. The code has placed greater requirements on curtain walling and cladding products, and introduces a thorough list of tests that must be conducted. While it represents in itself a challenge to all stakeholders, there are new stringent requirements with respect to installation and the quality of workmanship. It’s vital that all installations are ‘as-tested.’

High-rise and super high-rise equates to greater risk so it is imperative that systems that go into these buildings are tested accordingly, in the most demanding way, because there is little margin for failure. Of course, it is possible to test well. However unless the installation replicates that, you are introducing risk.

In the past, elements that are designed specifically to mitigate the fire are invariably left out or not actually installed properly. One particular element is the perimeter firestop which was often not installed correctly or there was a lack of compartmentation measures within large uninterrupted cavities behind cladding systems.

While the tough new regulations in Dubai, which are designed to prevent fires in high-rise towers, will certainly reduce risk and improve safety, it will be a challenge to the market to respond to these changes because contractors and consultants will be personally accountable for effective selection and use of materials.

Manufacturer perspective

For a company that is renowned internationally for its diverse range of fire-stopping insulation solutions, SIDERISE has a unique insight into the industry and the code. The company offers a range of innovative and industry-leading passive fire protection systems which provide compartmentation in high-rise buildings.

Commenting on the new revised code, Steve Swales, Chief Commercial Officer at SIDERISE said: “We have witnessed a large interest and uptake in system testing and have been involved in numerous tests to the various permissible standards.”

With respect to the fire performance of non-load bearing external cladding systems – whether applied to the face of building or fixed to and supported by a structural steel frame - SIDERISE has been involved in fire performance testing to the US standard NFPA 285 and British standard BS 8414 Parts 1 and 2, both of which are permissible with respect to the new UAE Fire and Safety Code of Practice.

This testing has been carried out by cladding panel suppliers of all types including aluminium cladding material and aluminium composite panel providers (ACP) – and separately in conjunction with thermal insulation stakeholders.

“The market has been stimulated to ensure that all systems are code-compliant,” added Steve Swales. “There has also been a rigorous evaluation of compliant barriers which fit within the various systems.”

Compliant solutions

The code states that cavity barriers shall be incorporated into façade design at every floor, horizontally and vertically, to restrict flame spread. There is also specific performance and location requirements including where the cavity is a necessary part of ventilated façade design and needs to be maintained.

In this case, ‘open-state’ cavity barriers are used which comprise advanced intumescent materials that allow ventilation and drainage in the cold state, but close in a fire, providing separation in the cavity. These have typically been included as horizontal barriers in recent tests for open joint cladding systems, in conjunction with full width seals used as vertical cavity barriers. In other closed-joint panel system tests, where there is no ventilation requirement, SIDERISE cavity barriers used both horizontally or vertically are full width seals which have also been tested with respect to the code.

While the new code will not be applied retrospectively, when existing buildings undergo maintenance, any cladding or system which is non-compliant to the current code will provide an opportunity to install compartmentation measures using cavity barriers, such as those provided by SIDERISE which lend themselves to retrospective installation.

It is recognised that the spread from floor-to-floor and over the façade of a building can lead to catastrophe. As well as providing greater requirements on curtain walling and cladding products all building products and systems will have to be independently tested, audited and certified by approved third party bodies. The code will also place new responsibilities on building owners to maintain the life safety measures within their buildings.

Once a fire safety strategy is in place, it needs to be managed and maintained through the life of the building, a crucial consideration when you consider a building occupier might change the building fabric or materials. Unless the strategy has ongoing review, every change to the building can potentially increase risk and jeopardise life safety.

Graham Laws, Business Development Officer at Siderise Group, provides some sound advice on HVAC acoustic design and offers up proven ways to deal with a potentially noisy issue.

Noise is an all pervasive facet in our lives, from the early morning alarm clock right the way through our working day. But does it need to be that way? When you consider that the estimated cost of noise pollution runs into billions of pounds according to DEFRA, architects and engineers have had to think long and hard on how to build out noise from buildings. With building services a well-known source of undesirable noise and vibration, what is the most cost effective way to reduce undesirable sound, whilst delivering noise control, air flow and thermal performance? Graham Laws, Business Development Officer at Siderise Group, provides some sound advice on HVAC acoustic design and offers up proven ways to deal with a potentially noisy issue.

Noise and vibration in building services come from a wide range of mechanical and electrical systems, everything from fans to variable air volume systems, grilles and diffusers to roof-top units, fan coil units to chillers, compressors and condensers, pumps and stand-by generators, boilers and cooling towers. All this unwanted noise can make a workplace environment uncomfortable and less productive.

Through the increased requirements for energy efficiency, buildings are better insulated and isolated, both thermally and acoustically. However, this further drives the need for ventilation and thermal management, and this required airflow can then introduce noise issues of its own, both break-out and in-line noise.

Sound matters

Break-out noise is where sound transmits through the wall of ducting and into the room through which the ductwork is travelling. In-line (duct-borne) noise or noise traveling through ductwork, can create unwelcome high levels of background noise if not properly managed. This noise can raise stress levels in the workplace, harming communication and concentration and increasing fatigue. A poorly designed acoustic solution can potentially exacerbate issues by causing regenerative noise, and negatively affecting airflow.

An additional issue to mechanically generated noise via the HVAC system is cross- talk, whereby speech privacy is compromised by room-to-room transmission via the ventilation system. A good example is in an office building where employees on one floor might hear conversations via the return grille. Even when intelligibility is not an issue, concentration and therefore productivity can be affected by those in adjoining rooms.

The essence of optimal practise comes down to:

  1. Understanding the legislative requirements of the building
  2. Understanding the design requirements of the building
  3. Optimising noise control treatments at source
  4. Optimising system design for airflow and regenerative noise
  5. Minimising breakout from ducts and air handling units
  6. Minimising structure borne noise

Meeting requirements

All buildings represent unique challenges, whether they are offices, schools, hospitals or commercial structures. In the education sector, noise and poor acoustics are an increasingly important issue. For example, in a school, there will be both separation requirements and background noise level requirements for the project.

These can be provided as a single figure rating or noise rating (NR) value, or as octave band values. When it comes to the design of a building, it’s vital to know the function of each room, and both the desired speech privacy and NR level. NR values are a way of describing, as a single figure, a measured noise level that takes into account the frequency content of the noise.

They are often used in the measurement of noise from mechanical sources such as air conditioning systems in environments such as hotels, cinemas and schools. Most buildings will have an ‘in-room’ NR level requirement based on function. For example, typical noise rating values for a concert hall or church would be NR25 while a school or hotel would be NR35, significantly less than say a factory or a noisier engineering environment which would have an NR70 rating. To ensure these levels are achieved, a given Sound Power Level (LwA) for the HVAC unit is required.

Noise Control Treatments

In terms of the system design, air velocity within a duct system influences the noise levels significantly. Regenerated noise can be created by transition pieces, bends, dampers, grilles and diffusers. Regenerated noise can be reduced by limiting the air velocities within the duct system, by easing transitions in the system design and by ensuring that internal acoustic treatments contain chamfers where appropriate to reduce the turbulent effect of sudden changes in opening or direction.

When two adjacent or closely positioned rooms are sharing the same ductwork, sound travels within ducts and will decrease the room-to-room sound insulation dramatically. This will of course impact speech privacy and negatively affect the working environment through disturbance.

Vibration and sound energy from HVAC operation will transmit to a structure and be redistributed around a building. By isolating your systems from the structure before it has a chance to vibrate, through isolation mounts or decoupled through flexible linkages from the structure via the noise source and the duct runs, another path of noise has been reduced through physical materials.

Solutions provider to manufacturers

With more than 40 years’ experience providing noise control treatments to manufacturers in the HVAC sector, SIDERISE offers a range of noise control solutions which can be tailored to meet project specific design and performance requirements. SIDERISE HV-NC noise control solutions, for example, are tailored to the octave band requirements of your HVAC unit, thereby delivering the optimum acoustic performance at the minimum cost. Manufactured from high performance open cell acoustic foam, parts are designed to ease airflow and lower regenerative noise, and the lining treatment is engineered to deliver the lowest possible Sound Power (LwA). These acoustic solutions give exceptional noise absorption, yielding reduced airborne noise at inlets and outlets, and lowering case radiated noise.

Lining kits are Class 0 fire rated to EN 13501-1 to comply with Building Regulations Approved Document B.

Offering ease of installation, SIDERISE noise control solutions are supplied as a pre-cut kit, backed with high performance modified acrylic adhesive for rapid installation on a manufacturer’s assembly-line; and offer exceptional performance for fan coil units, air handling units and heat exchangers.

Remedial treatment – building services

For an existing building with a ductwork ‘in-line’ noise problem, SoundPAC is an easy and cost-efficient way to introduce noise control. At the terminal ends, where air is being delivered to the occupied spaces, you can remove the grille and simply install the SoundPAC inserts. Inherently flexible, the inserts are ideally suited to retro-fit installation, particularly in situations where there is minimal access and/or where less disruption is a consideration. For ‘duct noise breakout’ another solution, which contributes well to quiet air-handling, are the DWX and DPF-RL external acoustic treatments, which are externally applied. Easy to install without disturbing the HVAC system, this solution reduces break-out noise by providing a combination of acoustic absorption and sound reduction via inherently damped flexible mass membrane.

We live in a very noisy world but by proactively considering potential acoustic problems at the design stage of an HVAC system and adding sound control measures to minimise unwanted noise, building owners will have a far quieter system, which in the end, can go a long way towards promoting comfort and productivity.

SIDERISE through a broad range of products and solutions are able to provide a holistic treatment to all areas of HVAC noise, ensure that a peaceful, stress-free and productive environment is experienced by all.

With 40 per cent of fatalities (according to the DCLG) being a result of smoke and noxious gases, Siderise’s Chris Hall considers the importance of passive fire protection in high-rise buildings to mitigate the effects of fire to save lives.

When you consider that asphyxiation from smoke and noxious gases accounts for more than 40 per cent of fatalities (according to the DCLG) and that most deaths happen to people who were not in the room where the fire originated, it is easy to see why firestops are critical to prevent the passage of flames and noxious gases from one floor to the next. Chris Hall, Commercial Development Officer of SIDERISE feels that passive fire protection solutions play a vital role in high-rise buildings mitigating the effects of fire, saving lives and property.

Fires in high-rise buildings generate large quantities of smoke that tend to spread vertically throughout the building, even if the fire is contained to only one room. Smoke travels at up to 130 metres every minute and whilst most people can easily move at this rate in normal circumstances, the majority of survivors of fires stated that smoke restricted their ability to see to no more than 4 metres. 

When the linear gap at perimeter edge between the floor and curtain wall is not properly sealed, flames and smoke will spread vertically to higher floors. Addressing these linear gaps by properly installing firestops, maintains the floors fire compartmentation of the building. This delays vertical smoke-spread and reduces the risk of smoke-related deaths in the upper floors of the building.

Safe solution

The Perimeter barrier firestops seal the linear gap between the edge of the compartment floor slab and external curtain wall. Due to project designs and site tolerances, this linear gap can be variable, so the firestop system used needs to have a degree of ‘dynamic’ movement capability – compression and recovery – in order to accommodate serviceability movement. What is critical is the firestop system must do this in combination with the primary functional requirement, which is to maintain continuity of fire resistance between the compartment floor and the external wall. The installed firestop system needs to match the same period of fire resistance as the compartment floor.

All firestop systems need to be tested to two criteria – Integrity and Insulation (EI).

Integrity (E) refers to the ability of the system to prevent the passage of flame, smoke and combustible gases either through, around the material or through joints in an assembly; while Insulation (I) refers to a measure of the increase in conducted heat transferred from the exposed to unexposed surfaces of 180°C rise above ambient.

These two criteria are critical in the development of curtain wall perimeter firestop products. The most effective products combine a number of material features – density, thickness, resin content, fibre structure and controlled compression – which together determine the resistance properties.

When looking at the Integrity (E) criteria, the material chosen must be impervious to the transfer of flame and gases, easy to install with minimal site management and accommodate all real-world requirements at interfaces, joints and details.

In order to meet the fire and smoke stop requirements in all external façade applications, the Certifire Approved SIDERISE CW-FS perimeter barrier and firestop systems offer an unrivalled combination of fully-qualified performance, practical installation and service benefits.

The principal function of the SIDERISE CW system is to maintain continuity of fire resistance by sealing the linear gap between the compartment floors or walls and external curtain walls both horizontally and vertically.

SIDERISE perimeter barriers and firestops for curtain wallinguse a patented method of manufacture that provides a resilient lateral compression. This facilitates installation, ensures the requisite tight fit and enhances fire Integrity (E). Throughout the range, the materials comprise a one-piece product with a pre-compressed non-combustible stonewool core. The products also have integral aluminium foil facings to provide an overall Class A1 rating and excellent resistance to the passage of smoke. SIDERISE CW-FS perimeter barrier and firestop systems also offer an unrivalled combination of independent third party Certifire approved performance data for both horizontal and vertical applications, Certifire Certificate No CF563 refers.

The systems can offer tested fire rating options ranging from 30 minutes to five hours and can accommodate void widths up to 1200mm. In addition to providing an effective seal against the passage of smoke and fire, the products will also function as an effective acoustic barrier and plenum lining.

Sealing the voids

At the $135 million Al Fattan Crystal Towers, recently completed at the Dubai Marina in the UAE, fire safety was paramount in a development which houses hotel rooms, suites and residential apartments.

With both vertical and horizontal fire compartmentation requirements, the specification of SIDERISE CW-FS 120 firestops provided the contractor Cladtech with a one-stop-shop solution that could maintain a fire and smoke seal in one product and could successfully fill lineargaps at the podium levels in excess of 300mm.

For the two towers, Cladtech installed 12,000 LM of SIDERISE CW-FS 120 firestops including horizontal (floor slab) and vertical compartmentation. With the timeline on the project critical, the use of this dry fix system enabled the work to be completed quickly and efficiently, ready for handover to subcontractors.

Throughout the application, SIDERISE provided comprehensive support including drawing assistance, liaison with the authorities for approval, installation training and periodic site inspection and assistance.

Whilst specifying the correct product is vital, the quality of installation is equally as important. Contractors installing life saving measures such as perimeter barriers and firestops must have adequate training on the particular manufacturer’s products and be qualified to install it in the first place. When it comes to saving lives and protecting businesses and property, a well designed and installed system can make the difference.

Mike Carrick AMIOA, Head of Acoustics at Siderise Group, provides some sound advice on acoustic design and offers up proven ways to deal with common sound path problems.

The product of choice for many of the world’s leading architects, curtain wall systems have been increasingly specified across both the commercial and residential sectors in the UK.  A barrier to the elements, curtain walls give design creativity and are a happy marriage between metal framing and gleaming glass.  While they provide a cost-effective way to clad and glaze buildings and offer a wealth of benefits to building occupants, it’s vitally important that specifiers take into consideration the role of acoustics in curtain wall buildings.  Mike Carrick AMIOA, Head of Acoustics at Siderise Group, provides some sound advice on acoustic design and offers up proven ways to deal with common sound path problems.

The rise of modern lightweight construction, with walls that literally hang like curtains, has led to sound transmission issues and presented a number of issues when it comes to acoustics. This complex issue is not helped by specialist criteria and jargon which is often designed to baffle, when in fact it is not difficult to understand.

Weak point

Very careful consideration should be given to any potential weak point to ensure it does not become the ‘limiting factor’ in the overall sound transmission performance of a curtain wall building. The curtain wall, together with the movement joint, should all be considered as potential weak points and thoroughly assessed accordingly.

Whatever the building type, whether it be an office, hotel, school or apartment building, the client requires a sustainable structure that is fully robust and compliant to all building regulations and design criteria.

dB or not dB

When considering the transmission of airborne sound energy the applicable criteria (regulatory or otherwise), will usually be in decibels 'dB' in one of the following forms:-

A DnT,w is a final site-measured value and will be controlled by both the ‘Rw’ value of the floor slab or partition (direct sound transmission) and the Dnf,w value of the façade (flanking sound transmission).

An Rw value is a laboratory test value for a component or construction, such as a concrete floor slab, partition, window, door etc.

A Dnf,w value is a laboratory test value for a system, such as a curtain wall system, raised access floor or suspended ceiling system.

What’s critical is to understand the important and significant differences between these in order to validate or otherwise prove potential compliance. In general, site measured values cannot match those recorded in a sound laboratory. The difference will vary, depending on the method of test and actual performance levels, but a guide of 5-10dB minimum practical difference is commonly quoted.

Sound flanking

The Dnf,w value is a total flanking sound transmission of the façade system. It does, however, comprise a number of individual sound transmission paths with the five main path elements being the glazing element; the transoms; the structural element of the mullion; the hollow of the mullion; and the movement zone.

A number of factors directly affect the overall performance, including the span between the mullions and transom, the stiffness, number of façade brackets, type of glass, glass orientation, twin or single mullion or transom designs and importantly, the use of façade acoustic enhancement products.

The overall performance is a combination of all these path elements and can only be established by full façade testing in an accredited laboratory, which can be time consuming and very expensive. It is possible for a project noise consultant to look at specific project details at the slab edge, compare the design with known library data and assess the possible overall performance. However, this would not necessarily offer any guarantee of compliance.

When assessing any design, it is important to understand that the overall performance would be wholly controlled by the weakest path element, referred to as the ‘Performance Limiting Factor’ and therefore any design change or acoustic enhancement should only be considered if all other path elements are capable of meeting the same value or are being upgraded to meet the value.

Soundtight facades

SIDERISE offers a large range of tried and tested product enhancements specifically developed for the façade industry. Designed to reduce vertical and horizontal sound transmission in curtain wall buildings, this range includes a choice of effective and proven sound reduction solutions that deal with all common sound path problems and are frequently used to assist in reducing flanking transmission between adjacent internal areas.

Acoustic comfort in the built environment has become a concern to society and a challenge to designers. It is all too common when considering the specification of the seal between the slab edge and the facade, for product selection to be based exclusively in terms of compliance to the relevant fire regulations. For façade engineers, architects and their clients, it is essential that due consideration is given to both the acoustic implications and performance of the closure arrangement, ensuring any potential weak point in curtain walled buildings is controlled. The use of performance enhancing products will mitigate against these issues.

SIDERISE has just launched its new installation guidance video for its ‘Open State’ horizontal and vertical cavity fire barriers.

SIDERISE has just launched its new installation guidance video for its ‘Open State’ horizontal and vertical cavity fire barriers.

SIDERISE RH ‘Open State’ horizontal cavity barriers have been specifically designed to meet the requirements for cavity fire barriers used in drained and ventilated facades. These barriers ensure that the system will drain any moisture whilst maintaining airflow. In the event of fire they provide an effective hot smoke and fire seal.

SIDERISE RV vertical cavity barriers for rainscreen cladding are used to full fill the void between the external envelope and the internal structure. Their unique stonewool lamella core construction enables them to accommodate the serviceability movement that’s normally associated with rainscreen facades.

The new installation guidance video provides step by step guidance on how to install both the horizontal and vertical cavity fire barriers and is now available on the SIDERISE website, and the company YouTube channel.

The video forms part of the wide range of Site Services that the Facades technical team offers to customers to ensure that everything runs smoothly, from product selection to final installation.

To find out more, download our SIDERISE Site Services brochure, or contact a member of our Facades team.
