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.

Andy Kay, Global Facades Manager for Siderise, considers the devastating effects of the spread of fire and smoke in tall buildings and discusses how prevention through passive fire protection can save lives.

The following article was published in Windows & Façade Magazine - Fire & Safety Issue, January/February 2016.

The possibility of a fire in a tall building is always an emotive subject as the potential for loss of life is that much higher. Towering Inferno was one of the most popular movies of the 1970’s and the image of people gambling on the smallest chance of survival by jumping rather than been burned alive was an extremely powerful one. Unfortunately, fantasy all too often mimics real life and there is a long history of fatal fires in tall buildings dating back well over 60 years.  In 1946 a fire in the Winecoff Hotel1, Atlanta GA cost 119 lives, many as a result of jumping.  Other notable disasters such as the  Joelma Building1 in São Paulo, Brazil (179 deaths), Hotel Dupont Plaza1 in San Juan, Puerto Rico (97 deaths) and the Garley Building1; in Hong Kong (41 deaths) have made those responsible for building codes and regulations around the world sit up and take note.

India has also suffered its fair share of high rise fires.  Mantralaya is the administrative headquarters of the state government of Maharashtra2 in South Mumbai and in 2012 a faulty electrical circuit led to a fire in the 7 storey office block that killed 5 people and injured more than 20.  A major blaze broke out on the 21st floor of Lotus Business Park3 in Mumbai in 2014 and 21 firemen were stranded on the rooftop for several hours before finally being rescued.  One fireman unfortunately lost his life and the incident led to charges of negligence being levied against the owners, developers, occupiers, secretary, chairman and manager of the building.  Another Mumbai tragedy occurred in June 2013.  4 people were killed and 13 seriously injured when fire swept through the 14 storey IndusInd Bank3 building.

The most common cause of death in a fire is through smoke inhalation rather than the flames themselves.  Suffocation from smoke and noxious gasses account for more than 80% of fatalities.  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.  The majority of fatalities happen to people who were not in the room where the fire originated.  In 1996 a fire in Dusseldorf airport2 terminal building led to 7 people dying from the inhalation of noxious gasses.  They were all in a VIP lounge some 400 metres from the seat of the fire and were not even aware that the fire had occurred.  The smoke had travelled along ventilation ducts from the terminal to the lounge.  In all, 17 people died in the airport fire.

A key area of concern when it comes to fire and smoke spread is the gap maintained between a building slab edge and a façade designed to accommodate the movement of the structure.  The perimeter barrier firestop systems required in cladding systems vary dependant on the façade type.  In a curtain wall system the perimeter barrier sits behind the façade, between the edge of the building slab and the façade itself.  Its purpose is to act as a continuation of the floor slab right up to the façade whilst allowing for dynamic movement that can be caused by a number of differing factors.  Typically the taller the building, the more movement will need to be accommodated.  The installation of a perimeter barrier that cannot cope with the continual stresses imposed by positive and negative wind loads will eventually lead to a breakdown in the fire compartmentation measures designed to prevent the passage of flames and noxious gasses from one floor to the next.  The use of incorrect materials such as glass wool being used as firestops can also lead to unnecessary fire spread.  Glass wool has a melting point of 680° and so will not perform when an average fire reaches the peak temperatures of between 900° and 1200°.

Sprinklers are a vital component in restricting fires in tall buildings.  However, they should not be seen as an alternative to adequate passive fire protection measures.  Sprinklers often fail to fully extinguish a fire but will stop breakout through glazing components.  In these circumstances, a rapid increase in pressure occurs and smoke is then forced under pressure through any gaps.  The passive firestops tend to be even more critical in protecting lives and property in these circumstances.

So what are the key considerations when designing the perimeter barrier and firestop requirement?

  • The product should be tested to a recognised test standard to not only prove its ability to prevent the spread of flame but also its performance with regards to resisting a rise in temperature on the non fire side.  All products should be capable of equal fire insulation and integrity ratings.  These will normally be 120 minutes.
  • The product should be installed under compression and must have test evidence to show that it is capable of accommodating movement of a façade.  It is imperative that the installed seal is able to function effectively with due regard to all designed movement serviceability limits.  Curtain walling and cladding façade systems will deflect due to positive and negative windloads as well as occupational live loads.  These criteria are covered by EN 13116:2001.  Typically, a project may stipulate that the curtain walling system may have the following allowable deflection limits:

Under the declared wind loads the maximum frontal deflection of the curtain walling’s framing members shall not exceed L/200 or 15mm, whichever is the less, when measured between the points of support or anchorage to the building’s structure in compliance with EN 13116. [Extract from EN 13830]
These factors may inevitably combine to preclude the suitability and therefore, use of certain systems e.g. high density material slab products.

  • Perimeter barriers must be installed to provide horizontal compartmentation at every floor level.  Vertical cavity barriers should be provided as a minimum to fall in line with any compartment wall and more frequently if dictated by the fire strategy of the building.
  • Products should be fitted tightly around all bracketry to restrict the passage of smoke.  Where there is potential for gaps, the product must be sealed with a sealant that carries the same fire insulation and integrity rating as the perimeter barrier.
  • All installations should be in accordance with manufacturers’ instructions and where fixing brackets are required these should be fitted and spaced in accordance with a certified fire test report.
  • Products used for fire safety installation should carry an independent third party certification in order to ensure that the product supplied is the same as that tested.
  • The gap between the slab edge and the façade is often a weak point acoustically.  Any products used to improve the acoustic performance must not contribute to the fire load or inhibit the performance of the perimeter barrier.

Whilst specifying the correct product is vital, it is also important to put emphasis on the quality of installation.  Always make sure that any contractor employed in installing life safety measures such as perimeter barriers and firestops has had adequate training on the particular manufacturer’s product and is qualified to install it.  Well designed and installed systems can save many lives and protect businesses and property.

FAÇADES CONFERENCE

 

Wednesday 13 January 2016, BRE, Bucknall Lane, Watford, WD25 9XX

 

The Siderise Group in conjunction with BRE would like to invite you to attend a full day conference aimed at those companies and individuals involved in the design or installation of external façade systems.

 
 

BRE

Both the curtain wall and rainscreen facade industries are currently seeing a healthier construction market but, with an increasing number of players entering the sector, it is important that the quality of installation is maintained. BRE will be presenting on its third-party certification scheme for companies involved in the installation of firestop and cavity barrier systems. The scheme will aim to offer those companies a means of differentiation within the market, potentially removing the need to sub-contract the fire protection package.

 
 

Building Control Alliance

The Building Control Alliance in conjunction with NHBC have recently issued new guidance on the use of combustible cladding materials on residential buildings. Steve Evans, Chair of the BCA Technical Group will be presenting this document at the conference, the content of which may have major repercussions for those involved in the design and installation of rainscreen and other open state facade systems, including specific guidance relating to cavity barrier systems.

 
 

Arup

Professor Barbara Lane is a fellow at Arup and practice leader of their Fire Engineering team. Her presentation will focus on fire protection of curtain wall façades and will address the growing move towards greater fire protection within the spandrel zone.

 
 

Clarke Saunders Associates

Acoustics in façade design is always a concern because, unlike fire, noise is something that building occupants are exposed to on a daily basis. Ed Clarke of Clarke Saunders Associates will be presenting a paper on “Building Fabric Sound Insulation – An Acoustic Façade?”

 
 

Priedemann

Lars Anders is Managing Director of Priedemann, a façade consultancy practice that has built a worldwide reputation on its expertise. Lars will be presenting the paper “Facade Consultant and Facade Engineer united” which will focus on the best ways for these two disciplines to work together on a project.

 
 

Association for Specialist Fire Protection

The Association for Specialist Fire Protection is the trade body that’s the first port of call for the Government when looking at how the Building Regulations can best meet the fire considerations of building construction. Their Technical Manager, Niall Rowan, will be looking at the test procedures involved in fire barriers used in both curtain wall and rainscreen façades.

 
 

The Conference will include lunch and a tour of the BRE Innovation Park. This full day Conference will cost only £50.00 per person.

As we expect this to be a popular event we regret that we may unfortunately have to limit attendance to 2 personnel per company.

If you are interested in attending the conference please email us and include the following information:

  • Your company name
  • Your contact phone number (preferably mobile)

Consideration of Façade Acoustics - a report on the 7th Annual Façade Design & Engineering Conference, Qatar

The Middle East and in particular the Gulf States continue to be a hotbed of construction activity. The fall in the oil price has done little to dampen the enthusiasm of investors to invest money into ever taller, wider and more elaborately designed buildings. However, as beneficial as this boom is to the construction industry worldwide, it has to be conceded that not all the developments have been aesthetically sympathetic to their environment or the cultural heritage of the Arab states.

This was a major point of discussion at the recent 7th Annual Façade Design & Engineering Conference held in the Qatari capitol of Doha. Qatar was an apt setting for the conference with Doha itself having more than 40 towers taller than 100m and with the World Cup due to be played in country in 2022 the number of tall towers is set to increase dramatically. A discussion chaired by Eng. Ahmad Jassim Al Jolo of the Qatar Society of Engineers concluded that future developments should try to take more account of the ethnicity and history of the region.

Whether a building’s facade is constructed in shiny glass, traditional stone or burnished copper makes little difference to the occupants once they are at their desks or in their beds. For an office or a residential tower a primary focus is on the comfort of the inhabitants. In recent years it has become widely accepted that one of the major factors in determining comfort is the ability of the fabric of the building to either absorb or reflect noise. Acoustics are a particularly sensitive issue in curtain wall construction due to the hollow aluminium components acting as a conduit for sound waves.

Andrew Kay, the Global Façades Manager for SIDERISE, presented the paper “Consideration of Façade Acoustics”. The presentation considered the perspectives of different project stakeholders; an architect, for example, will want the building’s exterior to make a statement. This may be achieved by designing a wall of glass with clean glazing lines and minimal visuals behind the façade. Whilst aesthetically pleasing, a design like this can create acoustical issues since the best way to reduce sound transference is to introduce mass. The elements that comprise this mass can compromise the visual appeal of the façade.

Whilst many would like to live or work in an attractive building, other factors such as comfort and privacy play a major role in determining an occupant’s happiness in their environment. In the UK, local authorities receive more complaints about noise than any other issue.

The presentation also looked at the various sound transmission paths from ‘room to room’ and ‘floor to floor’ and demonstrated how relatively minor design changes could give major gains in acoustic performance. This was evidenced in a series of case studies, notably 1 Hyde Park, one of London’s most prestigious addresses where the innovative design of the mullions and transoms posed significant problems in meeting a high acoustic specification. SIDERISE developed a product specifically for this application that is only 31mm thick with an acoustic performance of 46dB Rw. This is equivalent to a 100mm partition wall.

The Olympic Village constructed in East London for the 2012 Games, which unsurprisingly had a high acoustic specification, is another example. With athletes from different countries potentially in adjacent rooms, privacy was deemed to be paramount. SIDERISE was the only company that could offer a viable solution acceptable to all three acoustic consultancies involved in the project.

SIDERISE prides itself on its ability to assist designers, contractors and building owners with solutions for both acoustic and passive fire applications. A team of qualified acousticians and fire engineers are available from conception stage through to commissioning of the building.

The Cladding Conference held at the Building Research Establishment at the start of November proved to be a great success. Over 120 delegates from across the cladding and façade industry attended and were addressed by leading figures in their field on a range of topics.  

The early morning session was taken up with the hot topics of Building Information Modelling and CE Marking of Curtain Wall Systems.  The BIM presentation was given by Graeme Tappenden of the Cabinet Office's BIM Task Group who gave a broad outline of the Government's aim to procure all their contracts via the BIM route by 2016.  There are still many questions on how this will affect the cladding industry and companies that desire more information would be advised to contact the Centre for Window & Cladding Technology (CWCT) to gain an industry perspective.

Stephen Ledbetter of the CWCT gave the next presentation on the CE marking of curtain wall systems. Although the product standard is still in development, CE marking becomes a legal reality for the curtain wall industry from July 2013.  Although many of the big players in the market are ready there is still a lot of work to be done by smaller companies and time is now getting short.

The morning was concluded with a look at cavity fire barriers used to provide compartmentation at the interface of the building's slab edge and  curtain wall façade.  Andrew Kay of Siderise, the major sponsor of the conference, explained the need to accommodate movement and looked at some case studies where failure of the fire breaks had led to loss of life and buildings such as the Torre Windsor Tower in Madrid.  By using products successfully tested to EN1364 part 4, designers and contractors can have confidence that the firestop will meet the requirement.

The BRE did a wonderful job of providing a hearty buffet lunch with one delegate heard saying "do they do weddings?"

The post lunch session was kicked off with a highly informative presentation on the fire testing of rainscreen façades.  This was given by Stephen Howard of the BRE and gave a great insight into the different test methods available for rainscreen systems, particularly the BS8414 full scale test that can be applied to both masonry backed systems and lightweight framed systems.  Anyone wishing to test to this standard should contact the BRE.

Stephen's presentation merged seamlessly into the next one on cavity fire barriers used in rainscreen façades.  Steve Swales of Siderise explained how the need to keep an airflow behind the façade conflicted with the need to put in the fire breaks but went on to show how fire requirements can be met by utilising fast reacting intumescents. The important criteria for designers and contractors to consider when choosing a suitable product are the closure time that the intumescent is able to achieve in a fire test and the longevity of the product when considering the application where it will be installed in a moisture zone for a minimum of 25 years.

Siderise was the first to market with a ventilated façade fire solution

The Association for Specialist Fire Protection have long been advocates of third party certification schemes for both products and the installation of those products.  Their CEO, Wilf Butcher gave a lively presentation explaining the benefit of using such schemes.  For curtain wall contractors, by sub-contracting the fixing of the cavity fire barriers, they are able to get a Certificate of Conformity underwritten by the Certification Body that can mitigate their liability in the event of a fire.  Details of suitable schemes can be obtained from the ASFP.

The day was concluded with a presentation on acoustic treatments of curtain walls.  The acoustic requirement for reducing floor to floor sound transmission is becoming more and more onerous.  This can pose problems to designers, system manufacturers and installers alike.  Mike Carrick of Siderise is a member of the Institute of Acoustics and did a great job in explaining the problems and then showing some of the solutions that Siderise are able to offer to combat these problems.

The day was chaired by Mike Wood of Pilkington whose knowledge of all the topics discussed enabled him to excellently summarise the presentations and elicit questions from the audience.

The positive comments received from delegates have been numerous and based on these, Siderise will definitely be running similar events in the future.  Contact Siderise for a copy of the conference paper.

Siderise in conjunction with BRE and CWCT are promoting a conference that will address many issues around the fire protection of façades as well as the imminent introduction of CE marking for curtain wall systems.

With the number of high profile fires in tall buildings on the increase, the correct specification of fire protection measures in cladding and façade systems can play a critical role in saving both lives and property. Siderise Insulation in conjunction with the Building Research Establishment and The Centre for Window and Cladding Technology are promoting a conference that will address many issues around the fire protection of façades as well as the imminent introduction of CE marking for curtain wall systems.

The conference will be hosted at the BRE, Watford on the 1st November 2012. There will be 7 presentations throughout the day and the £75.00 (+VAT) enrolment fee will include lunch and a tour of the BRE Innovation Park. There will be exhibits from Siderise, Rockpanel, The Association for Specialist Fire Protection, The CWCT and Sharpfibre Ltd.

From 1st July 2013 all curtain wall systems will require a CE mark. This has major implications for many of the component manufacturers that supply product that is included within such a system.

From 1st July 2013 all curtain wall systems will require a CE mark. This has major implications for many of the component manufacturers that supply product that is included within such a system.

The current curtain wall product standard is BS EN 13830:2003. This covers fire performance, weather tightness, wind loading, other applied loads, impact and thermal transmittance but it is currently being revised in order to widen its scope ready for the implementation of CE marking. Part of this revision, to be completed by the end of 2012, includes the need for fire stopping to be tested to BS1364-4 and for a fire stopping manufacturer's product to be included in a curtain wall system the fire stop material will need its own independent CE mark.

Siderise Insulation Ltd. have been at the forefront of cavity barrier technology for over 35 years and their range of Lamatherm fire stops are widely regarded as market leaders in the field of façade fire protection. Siderise have always striven to ensure that they have the most comprehensive testing on their products and have now completed a unique BS1364-4 on their CW-FS fire barrier. The test was unique because it was carried out using a non-fire rated aluminium curtain wall system glazed with standard non fire rated double glazed units. The normal recommendation is for 1364-4 tests to be carried out using a fire rated steel façade but these are rarely used in real life and do not replicate the movement that will occur in an aluminium construction.

The Siderise test utilised a full scale aluminium façade with additional fire protection measures that enabled the test house, Exova Warringtonfire to run the test for 3.5 hours without integrity or insulation failure. During this time the floor slab deflected by up to 67 mm and the façade by up to 30 mm without product failure. This can only be achieved by products that have been engineered to have the rock fibres running in a vertical orientation (lamella) and it is unlikely that the majority of products that currently have a horizontal orientation will be able to accommodate these levels of movement and will therefore not be suitable for CE marked curtain wall constructions.

As a result of the test Siderise will be able to add CE marking to its long list of technical approvals including Certifire third party certification. In contrast to some other systems available in the market the Lamatherm CW-FS is a dry fit system which is easy and fast to install whilst giving all the movement and acoustic advantages.

Should you wish to know more about the test or if you are looking to CE mark a curtain wall system then please contact Siderise.
