ACOUSTIC PERFORMANCE IN SCHOOLS

/в , /от

In contrast to many other sectors, there is detailed acoustic performance guidance for educational buildings. Here Adrian Whitefoot, Technical Services Manager at Kalzip, looks at the requirements of Building Bulletin 93 and how the correct specification of building envelope solutions can help achieve these.

Ensuring good acoustics and minimising levels of noise in school environments is essential. A growing body of evidence has shown the impact of noise on academic performance and cognitive development. For example, a recent study from the Barcelona Institute for Global Health found that higher levels of traffic noise caused slower development in memory and attention among children aged 7 to 10.

The main source of legislation for acoustics is Approved Document E of the Building Regulations, and in particular section E4, which specifically relates to acoustics in schools. For guidance on achieving the required acoustic conditions, Approved Document E refers to Building Bulletin 93 (BB93), the guide for acoustic design published by the Department for Education. While section E4 of the Building Regulations does not apply to colleges and universities, the acoustic recommendations provided in BB93 may also be desirable in these environments and therefore can provide a design standard.

Building Bulletin 93 sets limits for the level of ambient noise in rooms and spaces within a school based on how it is used. For example, the limit in classrooms and general teaching areas in primary and secondary schools, including those used for music and drama, is 35dB LAeq,30mins for new buildings and 40dB LAeq,30mins for refurbished buildings. Higher limits are set for sports halls, dance studios and swimming pools, while lower limits are given for teaching spaces for students with special hearing and communication needs.

Noise pollution can come from a wide range of sources, especially in school environments. External sources include aircraft, traffic, rain impact, noise from playgrounds and outdoor sports, and sound transmitted from nearby school buildings. Internally, impact and airborne sound from students and teaching activities can be transferred between floors and through walls.

Noise reduction can be easily achieved with the use of the Kalzip Accoustic roof.

There are a number of measures that can be implemented in the specification of building envelope systems to improve the acoustic performance of both new build and refurbishment projects. Different insulation materials will have varying acoustic properties but one of the most effective methods for increasing sound insulation of roofing and facades is to increase the mass of the system. Its performance is governed by the ‘mass law’, which states that the sound insulation of a solid element will increase by approximately 5 dB per doubling of mass. With metal roofing systems this can be achieved by adding different densities and thicknesses of mineral wool or rigid slab insulation. Alternatively, for higher performance scenarios, various thicknesses of cementitious board can be introduced as part of the façade or roof build up. As a built-up solution, aluminium roofing and façade systems offer this flexibility to tailor the specification to meet the acoustic requirements.

In addition, acoustic and dampening membranes can also be used to increase sound insulation. For example, to reduce the sound of rain noise, an anti-drumming membrane can be bonded to the underside of an aluminium roofing system to achieve approximately a 6 dB reduction in sound intensity.

Controlling sound within teaching spaces must also be considered carefully when designing educational facilities. Excessive sound reverberation within a classroom can distort speech and make teaching and communication difficult. Building Bulletin 93 provides guidance on acceptable reverberation times (RT) depending on the intended use of the space. For example, for a new build nursery room or general purpose primary school classroom it is ≤ 0.6 seconds. In contrast, the same type of teaching space in a secondary school would only need to achieve a RT of ≤ 0.8 seconds. The correct specification of roofing and façade systems can help to minimise excessive reverberation as well. Perforated liners and structural decks can be introduced as part of the roof build-up to diffuse sound where improved sound absorption performance is required.

The Kalzip Accoustic roof is based on the proven Kalzip technology with the same flexibility.

Achieving the optimum specification to ensure acoustic targets are met alongside all other building performance and design requirements can be complex. That is why it is important to partner with a roofing and façade system manufacturer that can offer a wide array of solutions as well as technical support services. Leading manufacturers, such as Kalzip, will be able to use laboratory test reports and data from previous projects to provide specification guidance and assess the performance of a proposed system.

Ensuring the acoustic performance of school buildings is essential to provide an environment that supports learning and development. Building Bulletin 93 provides detailed guidelines, which the correct specification of building envelope materials and systems can help achieve.

KALZIP – „Pavilion Scheveningen“

/в , /от

Architecture on the Scheveningen waterfront

The Vision.

Scheveningen is an internationally known vacation destination and not only the largest but also the best frequented seaside resort of the Netherlands. Its endless beaches and the spectacular redesign of the beach boulevard in 2015 make this town worth a visit throughout the year. At this special place, the Dutch architect Wim de Bruijn has designed a unique pavilion, whose design and functionality has no equal. It opened to the public in 2021.

The impressive building at the end of Noordboulevard’s beachfront combines ‘the elegant shapes of the Morales-Boulevard with waves and shells at the beach, all together frozen still in a white composition of glass and steel’ describes de Bruijn of the new boulevard’s icon. At first, the roof shape of the wire frame model seemed to be impossible to construct but perfect teamwork by many different specialists made it possible.

Engineering:

The foundation of the exceptional 3D-shaped roof construction is Kalzip’s X-tail profile sheet. A vertically adjustable pipe construction made it possible to follow the designated contours of the standing seam roof cladding. This led to all the profiled sheets having different measurements, so the experts on site had to follow a strict installation plan which was provided by Kalzip. The steel substructure of the standing seam roof cladding prevents noise pollution from penetrating outwards and adapts to the wind movement on site

That was a very important subject to consider beforehand, since the pavilion is located precisely at the noise location of beachfront and boulevard (from stone to dune). The spectacular round shape and the aluminum roof cladding make this building an impressive eyecatcher from every direction.

Sustainability:

The three-storey building consists of a basement, a main floor with a terrace and a first floor with another huge terrace, that had to be ‘cut off’ the main roof to gain an exclusive elevated view onto the beach and the boulevard. But not only from the terrace you can enjoy the spectacular view, also through the insulated glass windows from the interior of the house, the beach feels as close as it gets. Daylight illuminates the main floor almost self-sustaining and contributes to the fulfilment of de Bruijn’s vision.

The pavilion has an excellent thermal insulation value (U-value=6), based on the combination of PIR and fiberglass systems that were used insulating the roof construction. The long-lasting aluminum consists almost fully of recycled materials and classifies as sustainable metal. The Noordboulevard covers most of its energy demand per solar panels which are also connected to the pavilion.

Teamwork:

To make de Bruijn’s vision a reality, the technical crew, Felspartner B.V. (Kalzip PremiumPartner) and Kalzip had to work as a synchronized team from the very beginning. It was crucial, that every specialist could bring in his experience as they began working with 3D models. A construction site at beachfront always brings its own challenges that could only be handled with a perfectly organized and well attuned team of experts. Teamwork, combined with skilled craftsmanship and communication at eye level led to an innovative and sustainable building, that blends in in its sensitive surroundings, connecting the elements of ocean, beach and water trough state of the art architecture and efficiency.

Kalzip – There’s no way to do it better.

Sustainable production halls at TRUMPF

/в , /от

New buildings on the company premises of TRUMPF near Stuttgart:
Industrial buildings as electricity supplier

Large module for small technology. This was the theme of Kalzip’s involvement in the completion of the Trumpf manufacturing halls in Ditzingen. Three halls were fitted with Kalzip roofs, which combine a modern design with an integrated solar roof solution.

The company premises of TRUMPF in Ditzingen near Stuttgart

Playing with angles and heights

TRUMPF has been providing ready-made solutions in the fields of machine tools, laser technology, electronics, and power tools for almost 100 years. The architectural firm Barkow Leibinger from Berlin provided the design for the newly constructed buildings. Instead of the usual simple flat roofs, the architects opted for dynamic-looking roof construction. Slightly pitched gable roofs and butterfly roofs with slopes of 5° each alternate three to four times per hall and form a straight line at the ridge and eaves when viewed from above.

The design from the Architekturgesellschaft Barkow Leibinger is playing with contrary angles

Active use of roof space

In addition, Kalzip contributed to a special feature with its roofing components. In contrast to other manufacturing halls, the new buildings in Ditzingen were largely covered with solar panels, which contribute to sustainable energy generation. The architects’ desire to achieve the highest possible utilisation of solar modules with a homogeneous surface area presented both the manufacturer Kalzip and the fabricators with challenges.

Appearance and function are going hand in hand

 

Practical challenges in transport and assembly

A further challenge was the special production in excess length. For the building project in Ditzingen, profiled sheets with a length of up to 28 metres and with up to 12 solar modules on one profile were created — making them the largest AluPlusSolar profiled sheets ever produced and delivered by Kalzip. The transport was correspondingly difficult: loaded onto an overlength lorry, the profiled sheets were permanently kept under surveillance by an escort vehicle belonging to the haulage company. In addition, a police escort accompanied the lorry on the route from the Kalzip plant in Koblenz via the motorway to the construction site in Ditzingen. Kalzip profiled sheets were installed as the final layer. Due to roof permeations and transitions, the sheets were produced in different lengths accordingly.

To be able to connect the solar modules and with the inverter, the fitters had to install each panel individually, which required a special effort from the team: «We have installed Kalzip systems before, but never on this scale. Placed on the standing seam of the previous profiled panel, around 11 installers had to hold the panel at an angle so that the electrician could connect the wires underneath,» explains Tobias Brohmann.

The dimension of the solar modules as a challenge on the construction side

Enough electricity for a whole village

But all the hard work paid off. The highest possible utilisation of solar panels was achieved. Except for a few centimetres of edge strips and at roof intersections, solar panels have been installed on the roof surfaces of a total of about 15,200 m2 over the entire area. A total of around 10,000 panels achieve an output of 1,138.5 kWp — an amount of energy to supply 100 one-family houses with electricity — and thus ensure sustainable and ecological energy generation.

Development of the German Air Traffic Control Campus

/в /от

The German Air Traffic Control training centre in Kaufbeuren:
tradition and modernity brought into harmony

Since 2017, German Air Navigation Services (DFS) has not only provided training in the civil sector but has also taken over military air navigation services training in cooperation with the German Bundeswehr. The Kaufbeuren campus was expanded and converted to offer 60 to 80 trainees per year the best possible conditions for their courses.

The German Air Traffic Control campus in Kaufbeuren

State-of-the-art technology

The heart of the campus is the newly built training centre, where the basic and specialised training of trainees to become air traffic controllers and flight advisers takes place. In order to be perfectly prepared for the highly technical professional environment in which they will later be working, DFS offers state-of-the-art technology: Paperless and exclusively digital training materials are already standard, and the simulator rooms are impressively close to reality. The other training rooms also offer everything a technician’s heart could wish for in a modern training centre.

Here, the future air traffic controllers and flight advisors will find ideal training conditions

 

The challenge of transferring this contemporary and technically advanced working and learning from the inside to the building envelope was the task of the office Henn Architekten-Ingenieure from Munich. Their design of the training centre goes to extremes: the basic form of the building corpus with a gable roof, as can be found thousands of times in the surrounding Swabian towns and communities, forms the core of the design language. In contrast, there is a radical reduction, the design is limited purely to surface and structure and thus sets an exclamation mark.

Oriented towards the region and yet completely independent in its aesthetics

Reduction down to the last detail

What appears so simple at first glance only succeeds on closer examination thanks to many well thought-out details. The lowest floor with its continuous glass façades forms the base of the building, the concise gable roof corpus seems to float on it. Even on closer examination, there are no supporting columns to be found — the technical properties of the material make this possible. The rainwater drainage system is also perfectly integrated into the design and, as a functional element, does not destroy the basic concept. Hidden under the building envelope, they can ideally fulfil their task thanks to the visible surface of the profiles. The company Pröckl GmbH was responsible for the execution of the project.

Clear edges as far as the eye can see. They characterise the design by Henn Architekten-Ingenieure.

Seeing, but not being seen

The perforated profile of the Kalzip profiled sheets 65/400, which are used for both the façade and the roof, also provides another functional feature. They allow a view of the outside from the inside, whereas the view of the inside of the building from the outside is not possible due to the aluminium cladding and the façade behind it.

This is how light metal can seem. The perforated Kalzip profiles create a play of transparency.

Building of the Ajman-Kadyrow-Mosque

/в , /от

The Ajman-Kadyrow-Mosque in Chenya:
Russias most modern Mosque

 

Kalzip solves structural challenges

In May 2014, the Ajman Kadyrov Mosque in the city of Argun in Chechnya was ceremoniously opened. Kalzip also contributed to this celebration with its roof structures in high dimensions. The Ajman Kadyrov Mosque, also known as «Mother Heart», is considered Russia’s first ultra-modern mosque.

The building site in Argun had enormous challenges for the construction to overcome

Traditional components, new interpretations

The architecture of the building is particularly striking: Instead of the classic square ground plan with dome and imperial spires, the mosque designed by the Turkish architect Deniz Jeyhun Baikan uses a modern formal language. The roof forms a hemisphere that appears to rise from the ground when viewed from the main entrance. Three other sides let daylight into the interior through large glass fronts and at the same time connect the main building with the three minarets.

In order to realise the architect’s visions, a well thought-out plan was needed. The special geometry of the building had to be taken into account, which led to an unsatisfactory result in the first attempt at a solution. The ornaments were to be projected onto the dome. Due to the geometry of the building, the model would have run in different places and been unrecognisable as such from the viewer’s perspective. But equipped with the appropriate software, Kalzip was first able to calculate a surface from the measurement of the roof from around 2,000 points, reflecting the points on the convex dome. The ornamental model was then transferred from the existing image file onto the surface created in this graphic and aligned in such a way that no distortions were created. In addition, the model enabled the necessary material to be prefabricated and delivered at the Kalzip factory in Koblenz for an exact fit.

From Rendering to implementation

To ensure a satisfactory result, some construction challenges had to be managed. For example, the unevenness of the concrete dome was levelled out to allow the use of Kalzip’s Flexikon substructure. The visible layer under the ornaments was laid with flat sheets from Kalzip, which were already coated in the factory with a «copper antique» colour.

Assembling of the gold-colored ornaments with substructure on the laid flat sheets 

Golden by day — colourful by night

Thanks to the complex construction, the oriental ornamentation is particularly effective regardless of the time of day. The gold-anodised aluminium panels with a matt surface gently reflect the daylight and invite visitors to linger. With the concealed LED lighting, the roof is illuminated at night underneath the ornaments in different colours, enhancing the three-dimensional effect. The heating system, which is also invisible, ensures unrestricted operation even in the cold winter months and avoids damage from sliding snow.

The new building of Tenerife Airport has a Kalzip Standing seam roof

/в , /от

The Tenerife South Airport’s connection building is expected to increase the airport’s size by 50 per cent

In 2018 the Government of Tenerife decide to extend the Island’s Airport. For the amount of 53,9 million euros the new connection building was planned with Casadevall & Sayeras arquitectes commissioned to design the building. The new building will house, as a priority, security control filters and provide continuity from the gates to boarding lounges and the departure and arrival halls.

Kalzip is the specialist for airport roofs

In the past, architects have repeatedly relied on Kalzip for the planning of airport roofs. As a result, a certain know-how has developed at Kalzip over the years. This know-how was the key to success when it came to the tender for Tenerife Airport.

The curved roof, which shelters the entire interior space, is the main element of the project. It is composed of curved lattice beams and a light deck-type slab, complemented by the metallic finish of the roof based on aluminium standing seam Kalzip system, with a low reflective patina finish surface. The build-up utilises a double layer of rock wool insulation and Kalzip polyamide E clips to provide thermal and acoustic properties according to the project specification.

In the end over 11,750 sqm of Kalzip 65/333 in Kalzip AluPlusPatina Nature mill finish surface were installed on the new junction building.

Special design for a Junction Building

“We do not know of another passenger terminal in which a new ad hoc building has been designed basically to contain the security controls. We are talking about approximate dimensions of 150 meters long by 95 deep. Our proposal aims, by means of a soft design «gesture», to encompass, cover, the entirety of the new space. We achieve this with an arc segment with a circumference of radius 150 meters. With this formal strategy, the façade surface is minimized, which we envisage entirely glazed. Thus, from the new departure lounges and the adjacent circulation space, it is possible to continue enjoying the marvellous maritime profile.” Said Dolors Sayeras, one of the projects leading architects.

Linear transverse skylights emphasize the curved character of the roof and direct passengers in their transit from the ground side to the air side, achieving a diaphanous and light interior space, diffusing the light evenly thanks to a semi-white and white false ceiling permeable to vision.

Integrated PV Solution powered by Kalzip

/в , /от

Innovative Solar building techniques for a new facility building at Prestwick

 

The bonded solution is streamlined to the roof and allows you to read the building form.

 

The creation of an important new research facility at Prestwick in Scotland has included the largest installation to date of the innovative new AluPlusSolar system developed by Kalzip®, with the photovoltaics being integrated into the manufacturer’s standing seam roof by one of its longest established Teamkal contractors.

The 8,000 m2 building was designed by Glasgow-based Hypostyle Architects with Balfour Beatty appointed as main contractor. Fowler McKenzie, which operates across the whole of Scotland from its premises in Aberdeen, is the roofing and cladding specialist which undertook the entire envelope package and was responsible for putting Kalzip AluPlusSolar forward to the project team.

AluPlusSolar is a versatile and highly energy efficient lightweight system that has been developed in conjunction with BIPVco who supplied the panels for bonding onto the Kalzip® 65/400 roof sheets. The latter were rolled to length on site for Fowler McKenzie’s teams to install directly across the full span of the barrel-vaulted structure. Crucially, the super thin PV laminate and connected equipment add just 3 Kg/m2 to the weight of the roof: a total saving of 8.5 tonnes across the development compared to standard systems – while providing a potential peak capacity of 126 kWp.

Fowler McKenzie has installed many Kalzip roofs in the past

The Managing Director of Fowler McKenzie, Phil McKenzie, commented: “Going back almost 20 years, we are the longest established member of Teamkal in Scotland and have been installing Kalzip® systems from well before that. This, however, was our first experience of installing the new Kalzip AluPlusSolar, and our first contract for Balfour Beatty in the Central Belt, as opposed to our work for them around Aberdeen.

“When we tendered for the contract, with Kalzip® 65/400 already specified, it was envisaged to install conventional PV panels over the top, but we suggested the use of Kalzip®  AluPlusSolar as an alternative which we were aware would offer time and cost savings.  It consequently delivered an 8.5 tonne weight saving across the whole building.”

Kalzip AluPlusSolar is made for flexible architectural requirements

The Kalzip AluPlusSolar profile can be produced in the full range of RAL colours as well as a variety of forms, including concave and convex to suit a wide variety of roof structures. Also being integrated and low in weight, they therefore offer architects and engineers greater flexibility compared to conventional PV arrays while delivering similar power output. With very low future maintenance implications, this all results in a far lower whole-life cost for a development.

The Commercial Director of BIPVco, Justin Canning explained: “Our laminates are very light and only a few millimetres thick, making them fully flexible; With conventional solar panels that are installed on a frame above the roof covering, there is the potential for wind load to cause damage – our panel is bonded direct to the roof so there are no gaps between the roof and the solar panel.”

Looking to the future, Justin added: “I’m very excited about our partnership with Kalzip® and very happy to have this significant project completed. This is a truly innovative approach to putting photovoltaics onto a commercial roof and is testament to the on-going collaboration between Kalzip® and BIPVco – the 2021 pipeline is looking very strong and we are working on projects around the globe.

“Architects love the fact there is no effect on the roof’s aesthetic, and there is far less maintenance during the life of the roof: the module is self-cleaning due to an outer layer of ETFE and this means we need far less access equipment for maintenance.  We foresee many more jobs on industrial buildings, sports stadia and other structures including residential and modular.”

The Associate at Hypostyle Architects dealing with the project, Steven Colvin, confirmed the positive implications for designers and other specifiers. He said: “The contrast between AluPlusSolar and other PV systems is vividly illustrated by the adjoining building at Prestwick, which we also designed with a Kalzip® roof that has the PV mounted on triangular assemblies — because of the roof angle — plus all the associated access walkways.

“Instead the bonded solution is streamlined to the roof so that you don’t really see it from the ground, and it allows you to just read the building form; while the client was very keen on the greatly reduced maintenance implications. Kalzip AluPlusSolar even rules out problems such as birds nesting under panels, and there are no shadows cast by them being lifted up – which can reduce the efficiency.”

The Project Manager for Balfour Beatty, Tony McKay also identified potential programme benefits to AluPlusSolar for future developments. He reflected: “Balfour Beatty in conjunction with Fowler McKenzie, Kalzip® and Hypostyle identified the benefits of the new PV system during the early roof build up design development phase.

“The Kalzip® solution has taken a considerable loading off the roof and reduces maintenance as we are only installing one product in lieu of a traditional PV panel and a walkway product. Aesthetically it also provides a better finish to the build. It also reduces the number of trades on the roof, which assists health and safety and reduces the likelihood of damage to the finished Kalzip sheet.

“The incorporation of this product into the design at a concept stage will allow further potential benefits to be realised. If incorporated early enough, it could reduce the structural steel section sizes and roof purlin section sizes and centres, which would reduce material costs and install time. This should be a focus for future projects.

“Balfour Beatty have a long history of works at Prestwick dating back to the 80’s, with more recent projects which I was involved with including the Bristow Helicopter Search and Rescue Hangar, also including a Kalzip®  roof and cladding. Aesthetically the AIC building with the Kalzip® roof and AluPlusSolar is the most impressive.

The BIPVco laminates were bonded on site

A final perspective on the practicalities of the system was offered by Fowler McKenzie’s specialist sub-contractor which bonded the PV laminates onto the Kalzip® profiles. The MD of Gribben Solar, Paul Gribben, concluded: “The installation of the PV laminates was seamless in terms of both bonding it to the Kalzip® sheets on site and the visual effect once installed. With no heavy ballast, complicated bracketry, framing or roof penetrations it was much quicker to install compared to conventional PV systems on the market.

“This was crucial given the climate while installing it so close to the sea on the west coast of Scotland, in the middle of winter.  In the last 10 years I’ve overseen the installation of over 35MW of solar photovoltaic systems, across hundreds of commercial/industrial rooftops here in the UK and the Kalzip® AluPlusSolar system stands out as my most favoured system to date: because it’s so lightweight, versatile in terms of output and so quick to install.”

 

The view from above — the AluPlusSolar system fits perfectly with the Kalzip 65/400

Kalzip Roof System offering Sound Performance over Aberdeen Event Complex

/в , /от

A high acoustic performance was needed for the new Event Complex in Aberdeen

Able to host international conferences, industry leading exhibitions and live performances, The Event Complex Aberdeen (TECA) opened in 2019 to wide acclaim for both its facilities and the structure’s stunning appearance: attributable in part to the choice of a roof design featuring Kalzip® standing seam profiles.

In fact, the manufacturer helped evolve a high-specification build-up which – once current restrictions allow concerts and conferences to resume – will provide an acoustic performance that can prevent sound break-out or any disruption from what is an unusually noisy setting.

The TECA is built for a capacity of 15,000 people

Aberdeen City Council has hailed the development as being expected to boost the country’s economy by £63 million a year. The main building, constructed at a cost of cost £333 million, has already hosted acclaimed bands and crucial business conferences, most notably the Offshore Europe Expo in 2019.

Representing a key element in the council’s long-term strategy, the extensive structure was designed by the highly regarded Keppie Architects and built by Robertson Construction. In addition to preventing noise disturbance from music events, the facility’s proximity to Aberdeen Airport, with its numerous commercial flights and helicopters ferrying workers out to the North Sea oil and gas platforms, further raised the bar on acoustic performance for the 15,000 capacity arena, and led to the involvement of Edinburgh based specialist consultancy, Sandy Brown.

Appraising the acoustician’s involvement, Sandy Brown stated: “During the design stages, we highlighted the need for significant areas of sound absorbent treatment to control reverberation in the arena and conference halls, and undertook computer modelling of various early design options. Then as part of the commissioning, a large arena sound system was used to simulate worst-case amplified music levels in the arena and main conference halls and the noise levels were confirmed to meet the criteria at all nearby dwellings.”

An Outstanding sound reduction was the main key for Kalzip

Kalzip® was able to supply the project team with a wealth of technical data and acoustic analysis from other high profile projects it has been involved with across Scotland; including the SSE Hydro Arena in Glasgow.  This therefore enabled the manufacturer to work with the architects and acoustician on evolving the ideal roof build-up to control both the noise of performances and the sort of low Hertz reverberation generated by helicopter rotors.

In order to achieve an outstanding 55 dB sound reduction figure, the roof features a bespoke Kalzip® system comprising 14 separate components, including rock mineral wool slabs for acoustic attenuation; while the 1mm gauge, 65/400 profile version of the manufacturer’s world renowned aluminium roofing system, with a stucco embossed finish, weathers the system.

The manufacturer’s ability to offer site rolling further facilitated the installation of 100+ metre lengths of the profile direct onto the roof structure, thereby avoiding the need for overlaps anywhere over the arena and enhancing the weather resistance of the envelope.

Kalzip® duly provided a 25 year guarantee for the completed installation through the system will deliver a minimum 40 year service life. With more of the material employed for cladding walls and the other roofs to the exhibition complex, a total of 27,000 m² of the 65/400 stucco embossed profile were supplied for the contract: the success of which has led to further work with Robertson Construction such as at Bertha Park in Perth.

The 7 stations of the Orange Line in Bangkok — Kalzip supplies roofing sheets

/в , /от

Bangkok’s metro network is getting a new rail line.

In 2017, the foundation stone was laid for Thailand’s new mega project. A complete metro line is to be built within seven years. At Easter time, the new MRT Orange Line is scheduled to open in 2024.

New construction and extension to the existing metro network

In total, the Orange Line is to be 35.86 km long and have 29 individual above-ground and underground metro stations. The first phase of construction is 23 km long and includes 17 of the 29 stations. About 14 km of the line will be underground with twin single-track tunnels, and about 9 km will be overground. The line will then start at the Taling Chan underground station west of the city centre, cross under the Chao Phraya River near the Somdet Phra Pin Klao Bridge and will connect to the MRTA depot located at the authority’s current office building. Further east, the planned Yellow Line is crossed at Lam Sari station. At Khlong Ban Ma station, the line merges into the elevated section and finally ends at Suwinthawong station.

Start of Kalzip installation in January 2021

A complete roofing concept was planned for the sections of the elevated railway line. For the 7 overground stations, Design Concept Co. Ltd planned with a hard roofing that should be sustainable and durable. It quickly became clear that a Kalzip roof was the right choice. The first roofing sheets for the first of the 7 stations were delivered in January 2021.
