"glass balustrade"

Designed and built by C Plus C Architectural Workshop. Large format curved glass panels up to 2400mm high x 3500mm girth have been manufactured by Bent & Curved Glass in a variety of glass types to meet the design requirements for thermal performance, privacy, night lighting effects while also maximising natural light and a sense of space and openness. Early consultation between architect, glass manufacturer and frame fabricator and a process of glass sampling, review and selection created the best project outcomes. The quality of these glass elements has made a significant contribution to the success of this exceptional project.

With completion of the restoration, the building is a leader in terms of energy efficiency and environmental profile and has received the prestigious LEED Platinum certification. Guardian Glass high performance glass products for the façade contributed directly to achieving this LEED certification.

Designed by Benson McCormack Architects and built by Hone Constructions. The curved glass elements seen at the ground level entry shopfronts and in the feature penthouse facades are key to the undulating design which becomes the signature for the “Wave” Apartments building. In particular the projecting curved façade at each end of the penthouse roof level is a major element of the architectural design and a feature that can be seen from afar. The sweep of the concrete rood appears to float above the skin of curved glass creating a dramatic visual effect.

The six-storey car dealership opens up to the south and city streets with a fully glazed façade construction. In the evening the building reveals itself as a glass shelf. Inside the showroom, the floors are connected to each other by air spaces, creating a mix of visual relationships.

The Victoria Tower is a skyscraper hotel located in the Kista district of Stockholm, Sweden. At 118-metres high, it is one of the tallest in Scandinavia. Designed by Wingardh Arkitektkontor AB, the building is wrapped entirely in a cloak of glass, standing like a lighthouse along the road between Stockholm and the city’s airport.

Designed by Woods Bagot Pty Ltd and built by Lend Lease Group, BCG manufactured curved heat strengthened laminated glass panels for the feature stair to the entry lobby of the first completed commercial tower at Barangaroo – International Towers Sydney (ITS) 2. Working closely with Woods Bagot Architects and fabricators F & D Normoyle Engineering, BCG assisted with the fine tuning of the detail design. BCG’s precision bending and laminating processes provided the quality of finish and timely supply required to ensure the successful completion of the project.

In museums, glass displays protect valuable artefacts from damage or distress, whilst presenting them in the best possible light. Sometimes the glass itself can act as an obstruction to the view. Unwanted glare, reflections or reduced lighting levels can obstruct visitors’ views through the glass, preventing precious works of art from being seen clearly and in their original colour and detail.

The unique spiral design of the tower is a remarkable architectural accomplishment, with an overall twist of 156 degrees clockwise – one of the most extreme twists in any architectural project. Each of the tower’s 52 floors is rotated through 3 degrees, leading to its twisted corkscrew shape.

Located in the Amsterdam Southeast district, the ING Pavilion is an inspiring and stimulating meeting place for employees on the campus, as well as local residents, students, visitors and entrepreneurs. Positioned at the centre of the ING campus, it’s also a high quality dining option and a multi-functional space for the whole community.

Didier Repellin, from the architectural firm RL & Associés, oversaw the project. As honorary Chief Architect of Historical Monuments and a member of the French Heritage Society (among other titles), he was the perfect choice for the renovation of the buildings and the grounds. His vision was to make use of the history of the city to embellish the ancient buildings and has done so by respecting the history of the Hôtel-Dieu while giving back the grounds to the inhabitants of Lyon.

Architects from APP Arch-Studio created a building that serves as a multi-functional cultural centre, hosting important musical events, painting and photography exhibitions, as well as theatrical performances and film screenings. Combining all these functions was made possible due to a clear division of the building into two spatial modules: the glazed part acts as a philharmonic hall, while the second part is visual and exhibit-like, comprising of photography studios and a small cinema room.

The headquarters of the BNL-BNP Paribas Group building is a stunning example of how to successfully combine innovative architectural design with optimum comfort and wellbeing for the building’s occupants. Due to the clever structural glazing, the aesthetics are visually appealing, reflecting the building’s surroundings on all sides and changing its appearance depending on the time of day and the weather.

Ferrero’s new global HQ gathers in one building with nearly 1,300 people, previously spread over five different offices. The building, with a total floor space of almost 30,000 m², opened in December 2019. The building is designed to evoke the atmosphere of an Italian square: a vast atrium is surrounded by two multi-storey office wings. Boon Edam was appointed to craft and install the golden revolving door, on behalf of facade builder Groven + Portal, who in turn worked for general contractor Felix Giorgetti. The colour of the revolving door makes a visual reference to the world-famous golden chocolate - Ferrero Rocher. The Casa Ferrero administrative building consists of two blocks built on a common basement. It was the combination of these plots, and the architectural skills, that resulted in what you see today: a building that is both impressive and elegant as well as being a pleasant and functional workplace for the employees of the food group. Ferrero’s colours are subtly incorporated into the classic facades, with bronze tones and a gilded effect over the windows as well as the entrance glass panels. This effect was achieved by applying a gold-coloured textile fabric to the laminated glass during the project’s construction. Behind the glass facade of the entrance, the most jaw-dropping area of Ferrero’s headquarters unfolds - a central atrium that connects the two blocks and is entirely covered by a glass roof. The spacious atrium is designed to function as a reception and meeting space. Horizontal circulation between the two blocks is facilitated by connecting walkways with a range of 20 meters. The vertical circulation occurs through panoramic glass elevators. The central atrium’s glass-roofed space is open to life within the company and encourages interaction between employees. This 11-storey building, including six upper levels (ground floor + 5 floors) and five lower levels, adapts perfectly to its urban surroundings. The office areas are spread over nine floors, taking advantage of maximum light for the interior space. Levels -3 to -5 include technical areas and parking spaces. Ferrero’s wish was for a functional and pleasant building for everyone who works there. We think they have achieved this in spades!

The Berkeley Hotel is a luxurious and iconic hotel, housed in the fashionable district of Knightsbridge, London. When renovations were required, Roger Stirk Harbour & Partners designed a glass façade entrance to the hotel. Boon Edam Ltd was consulted to provide a stylish entry solution to complement the updated lobby entrance and reflect the luxurious image of the Berkeley Hotel brand. Business Challenges The hotel entrance required a renovation which would give guests an instant welcome upon arrival, whilst also providing a practical function to meet access needs. For a hotel as prestigious as The Berkeley, first impressions are hugely important. The entrance and welcome given by a hotel provides the guest with an indication of what to expect from their stay, so therefore the entry solution was a key consideration within the renovation project. With a constant flow of visitors in and out of the lobby, the entrance door is vital in maintaining a comfortable climate and pleasant atmosphere for guests. As sliding or swinging doors bring in cold draughts, the specification called for a revolving door to keep out wind, noise and dust. The project architect specified that the door was to be fully automatic and made entirely of glass to match the newly renovated lobby. However, for a door to be fully automatic, there must be several sensors and buffers which would have impacted the all-glass aesthetic of the entrance. Boon Edam was appointed to provide a tailored solution which could meet all the specific functional requirements, without needing to compromise on the luxurious style and quality desired. The Boon Edam Solution A Custom Designed Crystal Tourniket Due to the high-end nature of The Berkeley Hotel, attention to detail was paramount. Multiple meetings were held with the architect to ensure that Boon Edam’s team of experts could fully capture all requirements to provide the perfect, bespoke solution. Boon Edam’s Crystal Tourniket door was selected for the entrance of The Berkley Hotel; one of the most impressive and eye-catching revolving doors available. A Crystal Tourniket is constructed almost entirely from glass, with added stainless steel accents to support the solidity of the door. The End Result The Berkeley Hotel is now home to a grand lobby entrance provided by Boon Edam, which utilises natural wood in the drum wall of the Crystal Tourniket revolving door to provide guests with a warm and elegant welcome. In combination with the all-glass door set and modern lighting, the bespoke solution truly reflects the prestigious Berkley Hotel brand.

With its glass walls, transparent façade and LED lighting, the Victor J. Koningsberger building, in the suburb of Uithof in Utrecht, cannot help but capture the eyes of all passers-by. The Viktor J. Koningsbergergebouw is dedicated to the faculties of Geosciences, Science and Medicine was designed by the renowned Rotterdam-based Ector Hoogstad Architects. This latest building addition to the University of Utrecht opted for a revolving door at their main entrance. The 3-winged Tourniket revolving door was custom-made and has been constructed almost entirely of glass. Director and project architect Joost Ector said, "The entrance had to be functional and recognisable, but also belong to the story of the building." The three central themes in the design of this iconic building are lightness, openness and transparency. All of these properties can be clearly seen in the building’s façade and play an important role at the main entrance. This bespoke revolving door towers at an impressive nine meters height. However, at this height issues such as rotating parts stand in the way, so a different solution needed to be chosen. Watch the video below to see which route architect Joost Ector selected and why.

Designed by Smart Design Studio, the building is an honest layering of old and new as expressed by the raw treatment of the exterior façade through to the smooth, modern interior. The rooftop addition connects the double-height banks of glass Breezway Louvres with an articulated aluminium roof folding down as a screen to the back of the building. The end result successfully incorporates flexible and functional office interiors and a two-bedroom rooftop apartment within a rigorously controlled contemporary architecture of old and new.

When entering the new Segerstedthuset building at the Uppsala University in Sweden – guests, students and employees alike are cheerfully greeted by a colourful revolving door. This unique door is an art installation by renowned American artist Spencer Finch and is aptly named ‘The Colour Wheel’. The artist is best known for installations that visualise his experience of the nature of light, colour, memory. The Uppsala University is the oldest university research university in the Nordic area and this large facility is located in Uppsala, Sweden - educating 45000 students. The new Segerstedthuset building, designed by 3XN is a multi-purpose extension to the university and was conceptualised and constructed as a modern workplace for researchers, university administration and management. Boon Edam Sweden was approached to supply Spencer Finch with two Tourniket revolving doors. The doors measure a diameter of 3000 mm and a total height of 2400 mm and the 6 glass door panels provide the canvas for the light installation artist to work his magic on. Colour film is fitted between the glass which creates a truly remarkable and memorable entry experience into this urban, communal space. The Segerstedthuset building was built as a sustainable building and proved to meet high environmental standards such as efficient energy use, sound material choices and a silent indoor environment. The building is environmentally certified according to the Sweden Green Building Council at the silver level.

Leading Australian community bank, IMB Bank, has installed a series of Boon Edam entrances, including all glass revolving doors, slimline speedgates and a swing access gate at its new building in Wollongong, NSW.IMB moved into the new building in early 2021, and immediately sought to make the entrance open and welcoming to visitors, with entrance security inside to protect valuable data, intellectual property and people.The Boon Edam technology selected is among the most stylish and efficient of the Boon Edam range used by major banks locally, Fortune 500 companies globally, and corporate HQs in 27 countries.The exterior of the building has two Boon Edam Crystal Tourniket all-glass revolving doors, which create a striking first impression. Inside, there are three Speedlane Lifeline Swing speedgates, including one wide lane suitable for disabled access. In one section, there is also a Winglock Swing access gate that separates off a designated meeting space.“After reviewing a range of product proposals, we found that Boon Edam’s range had the ideal combination of aesthetics and security that IMB was seeking,” said IMB Head of Facilities, Greg Dowd.“The security speedgates give us greater control over access to the building, and they alert us to any tailgating or access breaches. Limiting access to only authorised personnel not only protects our staff, but it also protects the data of our customers, which we always store securely,” he said.“As a further advantage, the Boon Edam team integrated the access control system with our RFID (Radio-Frequency Identification) system. This was a big help, because it meant the speedgates were sending data directly to our existing system.”Boon Edam Managing Director, Michael Fisher, says this impressive project will serve as a new benchmark for local financial institutions. “IMB has set the bar high with it’s new Wollongong facility. Every design element has been carefully thought out to be welcoming to visitors and intuitive to employees. We are delighted to have been selected to contribute to the success of this project.”“Boon Edam is a family-owned organisation with a history extending back nearly 150 years, so it is particularly satisfying to work with a community-minded company like IMB, with a similarly long and successful history,” said Mr Fisher.Responsive serviceIn addition to elegant aesthetics and intelligent security, IMB sought an entrance security partner with attentive service throughout the entire project, and then into after-sales service too.“The Boon Edam team was highly professional to work with, and responded adaptively to our needs. Early mornings were the best time for installation work, and their service team accommodated this need right from the start, without a hassle,” said Mr Dowd.“It was clear that Boon Edam takes great care in its products, and that its values as a company were aligned with IMB’s, which are strongly focused on community, family and quality.”Elegant aestheticsBoon Edam’s Speedlane Lifeline series is one of the slimmest on the market, with the cabinet housing measuring as little as 106mm. The slim nature of the speedgate makes it ideal for narrow entrances, lobbies and foyers, where sometimes an extra lane can be added due to its compact size.“The slim design and finishes of the speedgates was what attracted us to the Boon Edam product in the first place. Their overall designs are sleek, modern and in keeping with our foyer design. We could also customise the materials and colours to suit our foyer, and that really sealed the deal,” said Mr Dowd.“For the front entrance, we couldn’t look past an all-glass revolving door. It lets in an abundance of natural light, making the entire foyer a welcoming space for visitors and employees,” he said.Boon Edam’s Crystal Tourniket doors – available in single and multiple entrance options up to 3.5m diameter and height – are being introduced to Australasia after being proven internationally.The Crystal Tourniket is fully compliant with Australian Standard AS1288 (Glass in Buildings), which specifies safe glazing and installation practices when using glass in buildings.“The other Boon Edam product, the Winglock Swing, provides the ideal separation for our meeting space, without needing a full length Speedlane. It’s finishes and design also perfectly match the rest of our foyer,” said Mr Dowd.Boon Edam’s Winglock Swing is constructed from stainless steel and a single glass panel, creating an access gate that is elegant and unobtrusive in nature and design. Winglock is designed to manage bi-directional traffic with effortless ease, using smart, intuitive technology to guide each visitor through to their destination without delay or inconvenience.

Two high-end department stores Rokin 21 and Rokin 49 are rented by the Canadian Hudson's Bay Company (HBC), making this their Dutch headquarters. Both buildings have a new façade, which has been designed to blend in with their historic location. Authenticity is achieved with 3D curved aluminum façades and curtain walls housing enormous windows. The storefront display windows on the ground floor are 4.5 by 3 meters. A collaboration between Boon Edam and Stackdoor has resulted in an impressively tall entrance through a glass Tourniket original revolving door with a height of 4.3 meters.

The City of Boston is known for many things – from Fenway Park to the Boston Marathon to the bar from Cheers, the city is full of iconic landmarks, events, cultural assets, education centers, and more. The City is also recognised for its vast history, especially downtown, where hundred-year-old buildings have been preserved or restored. There is also a mixture of new property development, including 33 Congress Street, in the heart of the financial district, which combines the best of historical design with new construction. 33 Congress incorporates more than 400,000 square feet of office and retail space, transforming the historic neighborhood and positioning the area as a dynamic downtown destination. The project was designed by Arrowstreet, an award-winning architecture and design firm, and was led by Jason King, AIA, LEED, AP, BD+C, Senior Associate for Arrowstreet. Blending Historical Features with a Modern Design According to King, the 33 Congress Street building consisted of three different structures that were built at separate times: in 1904, 1906, and in 1922 and then all combined into one space. While the space functioned as one building, there were three separate elevator cores, sets of restrooms, sets of stairs, and more. Those entities needed to be reconfigured into one. The most striking feature of 33 Congress is a new, modern glass and steel structure, containing 6 additional floors of office space that sits on top of the original three masonry buildings. Another important project goal was to upgrade the main lobby to a modern design that allowed public access, increased security for building employees, and respected several historical aspects. “We needed a way to get people into the new, main elevator lobby quickly due to the high volume of traffic that we were anticipating would take place after the redesign,” King said. “We also wanted to create an entrance that would create a better flow of entry from the sidewalk into the building.” The original building had an existing revolving door, but it was small and surrounded by stone. “It was dark and uninviting,” King said. “We were creating an open and airy Class A lobby space and wanted visitors to clearly see the ornate, coffered ceiling and experience the grand and historic nature of the lobby as they entered.” Revolving Door and Speed Gates Provide Aesthetics and Function King implemented a Boon Edam Crystal Tourniket manual revolving door to lead visitors in the double height lobby space. The Crystal Tournket is constructed virtually completely from glass with only a few stainless steel accents to ensure the solidity of the revolving door. It fits seamlessly with modern glass facades but can also be a beautiful eye catcher in more traditional or classic designs. For employee access, the building’s previous design did not incorporate turnstiles to the elevator banks. “The building did have card reader access, but only at certain doors and locations,” King said. King installed four lanes of Boon Edam Lifeline Speedlane Swing speed gates and two Winglock Swing model access gates to provide secure employee access to the building’s upper floors. The Lifeline Speedlane Swing speed gate manages and channels the flow of people entering and moving around buildings. It employs sensors that detect visitors approaching, with pulsing light strips to guide the user. A sleep function saves on energy use. It can be customised with dimensional and glass choices, including corporate identity colors or other options, so that it either blends-in or stands-out from its surroundings. The Boon Edam Winglock Swing is constructed from stainless steel and a single glass panel, and is unobtrusive in nature and design. The access gate easily manages bi-directional traffic, with LED lights that signal if the gate is in use or on standby. The access gate ties into a manned security desk located near the front doors. Employees gain access to the building through either the Lifeline turnstiles, or a Winglock Swing access gate, while building visitors can receive credentials at the security desk. King said, “We started the process looking at Boon Edam from a security and an aesthetic standpoint. We went through multiple product options but always had a Boon Edam product as the basis of the design. We have been happy with Boon Edam entrance solutions and we are planning to use them again for future projects.”

The Burj Khalifa – formerly the Burj Dubai – is a legendary building that can only be described in superlatives. At 828 metres high, it is the tallest building in the world. The Burj Khalifa has 160 floors, more than any building in the world. The building also has the highest floor, the highest façade made of aluminium and glass, the highest nightclub and the highest restaurant, the highest service lift and the lift with the longest travel distance. Finally, the building has the highest positioned revolving doors ever installed in a façade worldwide. In less than 30 years, Dubai has become the leading city in the Middle East and is known for its architectural and technical excellence. The Burj Khalifa has become the symbol of this progress. The Burj Khalifa also takes the title of the highest structure in the world back to the Middle East; the Great Pyramid of Giza used to hold the title 4 millennia ago. International Collaboration The tower was designed by architectural firm Skidmore, Owings & Merril, known for their designs for the Willis Tower (formerly the Sears Tower) and the new One World Trade Center in New York. The three-pronged design is based on the spider lily desert flower and consists of three elements around a central core, with the elements spiralling upwards. It can rightly be called an international project: the construction team consisted of Samsung Engineering & Construction employees from South Korea in collaboration with Besix from Belgium and Arabtec from the United Arab Emirates. The UK consultancy Hyder Consulting was responsible for overseeing construction of the building. In total, companies from more than 30 different countries contributed to the construction of the Burj Khalifa. A Windy Challenge The wind is quite a challenge when building a skyscraper of this size. Without additional measures, the top of the building would move so much from side to side due to the wind that people would become seasick. Dubai is also regularly tested by the shamals: sandstorms that can last for days. As the outer façade of the Burj Khalifa contains an enormous amount of glass, these weather conditions presented a considerable challenge. The three-part design proved to be the solution because the spiral floors break the wind currents around the building, resulting in a stable structure. The World's Highest Revolving Doors Skidmore, Owings & Merril's design includes an observation platform on the 124th floor of the building. Two glass revolving doors provide access to this room. At 442 metres above the ground, these are the highest positioned revolving doors ever installed in the façade of a building. The revolving doors must also be able to withstand an extremely high wind load of at least 3000 Pascal, which corresponds to an F3 class tornado. The Burj Khalifa required two automatic revolving doors with a diameter of 3,000 mm and a total height of 2,700 mm; the cover could only be 300 mm high with the motor installed. Generally speaking, a revolving door with these specifications would only be able to withstand wind loads of up to 689 Pascal. It was clear, then, that not every revolving door manufacturer could supply an entrance that met these requirements. Challenge Accepted Koninklijke Boon Edam was one of only two companies invited to devise a system for this challenge. There were two main problems that had to be solved: the round sides of the revolving door had to be strong enough to resist the wind, and the door set had to be properly fixed so the door wings could not be blown off during a storm. Boon Edam worked closely with Mace, the Hyder Consulting Group, Samsung Engineering and Construction and Turner Construction, the subcontractor, to develop a system that met all these requirements. During the first phase of the process, the second company invited to tender had to give up because their design did not meet the challenging conditions on the 124th floor. Boon Edam persisted in its efforts, and after conducting various wind load and glass tests, it became possible to adapt the construction of the Tourniket to the requirements of the Burj Dubai. A Tornado-Proof Revolving Door at the Burj Khalifa Our proposal for the Burj Khalifa consisted of a Tourniket with specially reinforced door frames twice the width and thickness of a normal revolving door. These were securely anchored with special bolts under the floor to guarantee the structure's rigidity. Although most revolving doors are installed on the top of the subfloor, this door was installed under the top finish layer of the concrete floor. To guarantee the stability of the door set, an extra-thick steel frame was added to the structure. This allows the door wings to easily withstand the wind pressure. Expansion on the 148th Floor in 2014 Boon Edam installed the same specially designed Tourniket revolving door on the 148th floor as on the 124th floor. However, the new project brought an extra challenge: transporting all of the materials from the basement of the building to the 148th floor. First, the materials had to be transported in one lift to the 111th floor. They were then transferred to a second lift, from where everything had to be moved manually from the 149th floor to the 148th floor, to the door's location. Special Projects Based on Standard Solutions The revolving doors we created for the Burj Khalifa were an extreme challenge. The experience and expertise of our technicians combined with the tried and tested technology of the Tourniket enabled us to develop a successful solution. Both revolving doors are now used daily and give visitors a spectacular view of Dubai. The glass design beautifully complements the modern façade of the observation platform and puts Dubai's beautiful skyline in the spotlight.

TenneT's former head office at the Arnhems Buiten business park has been renovated and converted into one of the most sustainable office buildings in the Netherlands. It is now the head office of DNV GL's energy branch, which employs 2,500 energy experts worldwide. It is DNV GL's largest office building in the Netherlands. The site accommodates about 400 DNV GL employees and covers about 10,000 m2 of office and lab space. The building has achieved an A energy label thanks to innovations such as the use of seasonal thermal energy storage, solar panels, HR +++ glass and a highly efficient heating and cooling system. Boon Edam installed a sliding door at the main entrance, and three Speedlane Slide access gates and two Winglock 900 swing barrier gates in the central hall behind the main entrance to prevent unauthorised entry.
