Perhaps no other residential high-rise has created more buzz than the highly-anticipated Porsche Design Tower in Sunny Isles, Florida. A collaboration between Dezer Development and the Porsche Design Group, the 60-story, 132-residence luxury tower designed by Sieger Suarez Architects promises to deliver a new standard of cool.

The Department of Defense (DoD) published the Unified Facilities Criteria (UFC) 4-010-01 Antiterrorism Standards for Buildings as a mandatory guideline to mitigate the threats of terrorism against buildings and ensure the safety of the individuals that inhabit them. It applies to all newly constructed DoD Components, DoD inhabited buildings, billeting and high-occupancy housing, as well as already inhabited buildings where the renovation costs are 50% or more than the value of the building (for a complete list, please see UFC 4-010-01 section 1.8).

CSSBI Position Paper on CGSB Standards for Prefinished Sheet Steel Cladding The National Building Code of Canada 2010 includes references to two documents published by the Canadian General Standards Board (CGSB) dealing with prefinished sheet steel cladding. These documents are: • CAN/CGSB-93.3–M91 Prefinished Galvanized and Aluminum-Zinc Alloy Steel Sheet for Residential Use • CAN/CGSB-93.4–92 Galvanized Steel and Aluminum-Zinc Alloy Coated Steel Siding, Soffits and Fascia, Prefinished, Residential It is important to realize that there are no sheet steel products currently manufactured in Canada that meet the requirements contained in these CGSB standards.

It is not recommended for aggressive atmospheric exposure. 1.2 The prefinish system shall consist of a primer and topcoat continuously applied and cured within the paint manufacturer’s specifications on cleaned, pretreated, metallic-coated substrate. The pretreatment specified shall be zinc phosphate for galvanized steel and metal oxide pretreatment for aluminum-zinc alloy-coated steel, applied in accordance with the pretreatment manufacturer’s specifications.

Traditional parking garage designs used to have opaque fire rated building materials like concrete, masonry and drywall which made these spaces dark, cold and uninviting. That all changed, thanks to the emergence of new technology, clear, fire resistive glazing tested to ULC/CAN S101 up to 2 hours that are available in large sizes and low-iron glass make-ups with high visible light transmission for superior clarity and color neutrality.

About the ProjectTowering above the Dubai skyline, the Burj Khalifa is symbolic of the city’s emergence as one of the world’s top business and tourist destinations. The magnificent tower houses residences, a hotel and various commercial spaces, but its most popular attractions are the two observation decks located at the 124th and 148th floors. For visitors, the enthralling experience of visiting At The Top starts right from the moment they start to queue up to book their tickets. An extraordinary union of tasteful design, precision engineering and meticulous craftsmanship, the entrance lobby to the observation deck was created to give visitors a small glimpse of the beauty that awaits them a hundred storeys higher.The ChallengeWhile procuring the glass for the lobby to Dubai’s most well-known tourist attraction, we left no stone unturned in sourcing the highest grade materials. The customer had very specific needs regarding the colour of the panels. Achieving the right PVB colour combination was one of the biggest challenges we faced on this project. Further, we had to ensure that the glass used was durable and the coloured films did not fade over time. Working with Seele proved to be both demanding and rewarding. The company, known for developing Apple stores across the world, wanted to inspect every single pane of glass so that it met their high quality requirements. 

About Galliard HomesHaving serviced London’s real estate market for over a quarter of a century, Galliard Homes is the English capital’s largest privately owned residential developer. Over their years in the business, Galliard has become synonymous with regeneration, rejuvenation and reinvention. About Our CustomerProviding a wide range of façade design and engineering services to real estate companies across Europe, Yuanda has been transforming the continent’s skylines for over a decade. By offering a combination of European system design and Chinese materials and fabrication, Yuanda continues to provide world-class and cost-effective façade solutions to the UK, France, Germany and Switzerland. The BriefThe Harbour Central project was conceptualised to transform the London Docklands into an up-and-coming residential area. The project, which comprises 5 residential towers, boasts a total façade area of 63,000 square metres. The façades were designed to superimpose a metal mesh on the shadow box area and showcase the aesthetics of the blocks. Moreover, the team of architects at Rolfe Judd had very precise specialty glazing requirements for the buildings. “We discussed product aesthetics, construction and design considerations. The architect had a specific idea in mind regarding the kind of colour finish they required and Future Glass was able to provide the perfect gold and silver tones that were needed.”- Mr Alain Anthony, Design Director, Yuanda EuropeThe Future Glass SolutionThe search for the perfect glass led us across countries and continents. After an exhaustive search, the silver mesh was procured from Germany while the gold mesh was procured from Italy. Since the glass panels required were of a very large size, an innovative solution was sought by which panels of a maximum size of 1,500 mm x 4,000 mm were created with the metal mesh suspended in the cavity of the IGU. To put concerns about mesh sagging and distortion to rest, a sample panel was provided to the client. For energy efficiency, Climaguard Premium 2T, a high performance Low-E coated glass was procured from Guardian Glass in Europe. The glass itself is made up of a combination of products. The outer-lite is a clear ecoLAM (HS) of 10.76 mm. The expanded metal mesh infill is within a 24 mm black spacer with argon gas. Finally,  the inner lite is a 6 mm clear ecoFACADE (HS). Despite the complicated product combination, the performance specifications were designed to meet the client’s requirements perfectly. A total of about 4,100 square metres of finished insulated glass units with expanded metal mesh were provided for the Harbour Central project.The Future Glass AdvantageAt Future Glass’ state-of-the-art facility in UAE, a dedicated workforce was tasked with ensuring the high-specialty glass was treated in a sterile environment where temperature and humidity could be controlled. Each glass panel is handmade and pieced together under the supervision of qualified engineers. The finished glass panels were placed in IPPC-certified wooden crates for transport. As per local requirements, each piece was individually banded and then shipped to Yuanda’s Shenyani factory. From there, the panels were carefully assembled into a framing system that was delivered to the site in London. Despite the fact that the materials were sourced from various countries, the logistics and operations team took every precaution necessary to ensure zero breakages during the delivery process. In case panels needed to be replaced, we did what was necessary without impacting the timelines, even though it was difficult to procure smaller quantities of mesh from the supplier.

Sustainability, durability, fire resistance, structural performance and cost-effectiveness are some of the strongest reasons for using structural steel or cold-formed steel framing in mid-rise building construction. As a dependable, noncombustible material, steel-framed structures provide a wise investment for builders and the occupants who live and work in them. Steel structures provide long-term, consistent performance. • Steel framing will not rot, warp, split, crack or creep. • Steel framing is not vulnerable to termites. • Steel framing does not expand or contract with moisture content. • Steel framing is produced in strict accordance with national standards, with no regional variations. Steel is a noncombustible material and will not contribute to the spread of a fire. • Because steel is noncombustible, it reduces the fire risk to occupants, firefighters and property/business owners. Steel framing improves design efficiency, saves time, and reduces costs. • Steel framing provides a significantly greater strength-to-weight ratio than wood. • Steel framing allows for larger bays and wider frame spacing than wood construction. • Increased flexibility in bay spacing and framing layout maximizes usable floor space for owners and tenants. • Steel is typically fabricated off-site, reducing on-site labor, cycle time and construction waste. • Shorter construction time results in earlier occupancies and lower financing costs. Steel structures perform well during earthquakes and other extreme events. • Steel is a resilient material, with reserve strength and ductility that result in significant advantages in natural disasters such as hurricanes and earth- quakes, and in other extreme events like fire and blast. • Steel construction is engineered to provide a reliable, consistent load path. • Steel construction employs quality control and quality assurance procedures to ensure that the project requirements are met. Steel framing provides environmental benefits and complies with sustainable building standards. • Steel framing results in less scrap and job site waste than lumber. • Structural steel is continually recycled with a current recycling rate of 98 percent, meaning that these steels will still be in use hundreds of years from now, lessening impacts on future generations. • Steel, when recycled, loses none of its inherent properties and can be recycled into different products such as cars, bridges, cans, etc. • Steel can be used to comply with the requirements of sustainable design standards such as the International Green Construction Code (IgCC), ASHRAE Standard 189.1 (Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings), and the National Green Building Standard (ICC-700). Steel can also provide credit points for green building rating systems like the USGBC’s LEED (Leadership in Energy and Environmental Design) and the Green Building Initiative’s ANSI/GBI-01 (Green Building Assessment Protocol for Commercial Buildings).

Silicon Central was designed with sustainability at the forefront, populated by plants, water and natural light.Given Dubai’s harsh summers, we had to ensure the skylight allowed light to pass while filtering heat and minimising glare to ensure shoppers had a comfortable experience. Only 50% of the skylight is transparent, while the rest is opaque. We achieved the shading effect by using dotted ceramic frit in the panels. The main atrium skylight comprised triangle-shaped panels, which complicated the processing due to sharp corners. To ensure the delivery of all 6,000 panels seamlessly, we set up a multi-glass management system to easily track and handle the different glass sizes and codes.The skylight was installed successfully, and Silicon Central has become an integral part of the sustainable Silicon Oasis neighbourhood.

1.  About the ProjectOne of the most prestigious national pavilions at Expo 2020 Dubai, The German Pavilion, represented the Federal Republic of Germany's commitment to innovation and sustainability. Designed by renowned Berlin-based LAVA Architects, this 4,600 m² architectural showcase demonstrated Germany's leadership in environmental technology and intelligent building solutions through its unique "forest of steel poles" design.Project Specifications:Location: World Expo 2020 Dubai, UAEBuilding Owner: German Federal Ministry for Economic Affairs and EnergyArchitect: LAVA Architects, BerlinFacade Contractor: Future Glazing LLC, UAEMain Contractor: ARGE Deutscher Pavilion EXPO 2020 Dubai GbRInstallation Date: June 2021Exhibition Period: 6 months with over 3 million international visitorsTotal Pavilion Area: 4,600 m²FutureX Eclipse™ Intelligent Glazing Area: 113 m²2.

Scope of WorkProcess, deliver and install façade cone glazing for the dome.Build Up12mm FT HST Sunguard Neutral 50 + 16mm Black Warm Edge spacer + 88.4 Clear HSProject DetailsCaspian Waterfront is the reimagined building of the original government congress centre. In 2016, local developer Pasha Construction started transforming the building into a 120,000 sq. m. retail entertainment and leisure complex. Located on the shore of the Caspian Sea, the structure opens onto the waterfront on three sides.The retail centre’s unique structure posed a challenge. The building complex has geometric shapes similar to the Sydney Opera House, with shell roofs that reflect the surrounding water. The central flame tower has an eight-angled glass façade inspired by the country’s emblem, the eight-pointed star. Since the building would resemble a place of pride, we had to ensure that our panels surpassed every quality level. Due to the unique triangular shape of the glass panels extra care had to be taken during production, delivery and installation to prevent injury, breakage and damage.At Future Glass, we always prioritise quality. Our state-of-the-art processing facility enabled us to deliver the panels on time with minimal on-site rejections. Today, Caspian Waterfront has become a national symbol of Azerbaijan.

A question that homeowners often ask about steel roofing is “Will a steel roof be noisy when it rains?”. We’ve created this fact sheet to help answer that question. Residential steel roofing is available in many shapes and forms. The forming process provides not only strength, but when coupled with high quality build finishes, absorbs and deadens much of the noise. With the home insulation standards of today, you should not notice any difference in noise levels between roofing materials. 

It’s a fact that buildings consume two thirds of all the electricity produced in North America and one third of all the energy produced in North America. While it is recognized that cooling and heating costs can be reduced by adding insulation under the roof surface, there is a diminishing return on the strategy of increasing insulation to conserve energy costs. This is where “cool roofing” can play a role in further reducing the energy consumed, and in minimizing the Heat Island effect created in the big urban cities. Cool roofing relies on the properties of reflectivity and emissivity of the roofing material. Reflectivity Reflectivity is the ability of the roof to reflect solar radiation back into the atmosphere. Its primary measure is solar reflectance - the proportion of the total solar radiation that is reflected back to the atmosphere. Any solar radiation that is not reflected is absorbed into the building envelope, requiring further energy to cool the building; or partially convected into the atmosphere increasing the ambient air temperature in the surrounding environment (Heat Island effect). The measure of reflectivity is the Solar Reflectance Index (SRI) which takes into account the properties of the material as well as the cooling effect of wind passing over the roof. The SRI for a low slope roof will be 0 for standard black (reflectance 0.05, emittance 0.90) and 100 for standard white (reflectance 0.80, emittance 0.90).

The new Robert B. Aikens Commons at the University of Michigan Law School was built on an unused grassy courtyard between Hutchins Hall and the legal research building. The proximity of the new common area to historic Hutchins Hall posed a unique challenge. The building code required a 2 hour fire rated barrier between them. The architects specified SuperLite® II-XL 120, a clear, fire resistive glazing product that meets the ASTM E-119 wall standard for up to 2 hours.

About the ProjectA new educational hub in the heart of Kuwait, the College of Business is known for its impeccable design and breathtaking facade. A part of Kuwait’s much larger Sabah Al Salem University complex, the college building is an interactive teaching and research space where students hone their business skills. The building’s unique architecture, with vertical louvre shades and expansive rooflines, was created to maximise the natural airflow while minimising solar penetration The ChallengeThe building had a roof of approx 4,000 sq. m., which would allow a large amount of heat to enter through the skylight. This posed a big challenge to the architects in order to manage the cooling loads for the building. Our brief was to make the building as energy-efficient as possible, which called for us to find a way to keep heat transmission to a minimum while also maximising light transmission. Finding the appropriate build-up for the skylight was key for the success of the project completion in the short term and for the operation of the building in the long term to ensure sufficient light disbursement and reduction of solar heat gain. The glass make up had to protect the interiors from the harsh sunlight while also ensuring that the sun’s movement did not leave parts of the building in darkness. The idea was to ensure uniform dispersion of sunlight so as to reduce the occurrence of shadows and contrasts within the space. 

Al Wasl Plaza was the heart of Dubai Expo 2020 and continues to remain the focal point of Expo City. The central dome, surrounded by a decorative garden and five buildings, truly reflects the theme, Connecting Minds, Creating the Future. Working on the Al Wasl Plaza required careful thought and consideration. We had to ensure that the three office buildings and two hotels enjoyed unobstructed views of the garden and dome while maintaining energy efficiency and privacy.  The project was designed by Chicago-based architecture firm Adrian Smith + Gordon Gill. Since the project was part of Expo 2020, which invited representatives from around the globe, we had to ensure we met and exceeded global glass and glazing standards. We understood that the buildings were the supporting cast for the dome and gardens, yet they played a crucial role in making the entire plaza the focal point of the Expo.

Project DescriptionOne of the most awe-inspiring pavilions at the Expo 2020, was the Korean Pavilion embodying the theme “Smart Korea, Moving the World Forward.” It was the fifth-largest exhibit at the Expo, and the entire pavilion was shaped like an octagon. The unique pyramid structure ensured enough light entered the pavilion, while the north façade had rotating cubes that displayed myriad images and colours. To truly revel in the beauty of the pavilion, visitors could walk through the spiral aisles to admire the exhibits inside while still catching glimpses of the extraordinary view.About the ClientEstablished in 1962, the Korea Trade-Investment Promotion Agency (KOTRA) helps expand small and medium local businesses in overseas markets. They also work to attract foreign investment and develop international trade relations. KOTRA is known for spearheading innovative businesses and successfully building mutually beneficial partnerships. They sustain their growth through 127 offices worldwide, with over 15 offices in West Asia, including one in Dubai Media City.The BriefThe client wanted to truly showcase Korea’s forward-thinking vision. They designed a unique façade for the pavilion, with a steep slope on the south to let in adequate light and warmth. On the opposite side, a rotating cube protrudes from the basic slope, creating a dynamic façade that changes with

Introduction Sheet steel roofing and siding (cladding) is available in a wide variety of profiles, colours and paint systems. The modern prepainted systems used on Canadian-made products will provide decades of beautiful performance before there are any visible signs of deterioration of the paint surface. However, an important component of the cladding system is the fastener used to attach it to the structure. This fastener is not simply a screw; it is part of the roof or wall assembly and should be expected to provide the same long-term performance. This performance is not simply the capacity to safely hold the cladding in place, but also to match the colour and durability of the paint system. The selection of the correct screw for the job is the first step in the creation of a cladding system that will provide long-term performance. The next step is the installation. Installing screws in sheet steel cladding is commonplace and can be done very efficiently. The tool manufacturers have developed a wide range of options for installing fasteners into any type of substrate. Selecting the most appropriate tool will help the installation process.

Introduction Prefinished sheet steel building products, such as wall and roof cladding, liner sheet, flashing, and associated items, have experienced an enviable growth record during the past twenty years or so. Coil coated prefinished sheet steel in a variety of colours and paint systems has greatly enhanced the appearance of thousands of industrial, commercial, institutional, recreational, residential and farm buildings, providing an economical, durable and attractive alternative to traditional materials. As with all materials, a little care and maintenance pays off handsomely in terms of longevity and repair costs. The recommendations which follow have been learned at first hand and represent the collective industry experience with thin-film paint systems applied to metallic coated sheet steel by the coil coating process. In this publication the term “thin-film paint system” refers to a modified silicone polyester or a fluorocarbon type having a coating thickness about 25µm. When the guidelines listed below have been observed, thin-film paint systems have been used successfully for all types of environments other than severe industrial atmospheres which require special consideration. The guidelines are not intended for barrier coatings, laminates, and new formulations which have different characteristics than the thin-film paint systems on which these guidelines are predicated.

SAFTI FIRST® engineered a connection that allows the structural elements of the GPX® Architectural Series Framing System to support an integral sunshade system, instead of being hung in front of it. The Doolittle Bart Station is one of the first installations of the GPX® Architectural Series System with sunshade connections, which also include SLCC New Instruction and Administrative Building in Salt Lake City, UT.

Preface One of the objectives of the CSSBI and its members is the development of standards and technical publications that promote safety, performance and good practice. This "How To Series" of publications is an educational tool intended to give guidance to anyone specifying sheet steel building products. This particular publication is published as an aid to building owners as well as roofing and siding installers. It offers simple and practical recommendations for the selection, application and installation of light gauge steel cladding. This is a generic guide giving the basic details and should only supplement the specific recommendations or guidance published by the manufacturer appropriate to their own products. The views expressed in this guide are a collection of installation techniques and do not necessarily reflect those of all member companies of the CANADIAN SHEET STEEL BUILDING INSTITUTE. The material presented in this publication has been prepared for the general information of the reader. While the material is believed to be technically correct and in accordance with recognized good practice at the time of publication, it should not be used without first securing competent advice with respect to its suitability for any specific application. Neither the CANADIAN SHEET STEEL BUILDING INSTITUTE nor its Members warrant or assume liability for the suitability of this bulletin for any general or particular application.

This Fact Sheet has been written to describe some of the factors that affect the cost of prepainted sheet steel cladding products. The most significant factors are: colour, paint system, order quantity, Fabricator's inventory and profile selection. Recognition of the impact of these factors can help you select a prepainted sheet steel cladding system to fit the aesthetic and durability requirements of your project, and still stay within a budget. 

The 1890s-era Midtown Community Court in New York City—a New York Historic Landmark—is currently undergoing a five year, $18 million renovation that includes a 9,650-square-foot addition for a new elevator, lobby and stairwell featuring fire resistive glass and curtain wall. The system consists of SAFTI FIRST®’s SuperLite® II-XL 120 IGU in GPX® Curtain Wall System.

MAPEI’s Mapeheat™ radiant floor-heating system adds an extra touch of luxury to a five-star lodge.

Introduction Prefinished sheet steel is used on many building products from wall cladding, to architectural roofing to interior panels. Prefinished sheet steel has been used in Canada for over 30 years and there may be sites were the paint surface is in need of repainting. This bulletin is intended to give some guidance on repainting prefinished panels. Due to the diversity of factory applied prefinished systems, and the diversity of potential field applied repaint systems, it is impossible to offer one comprehensive repaint procedure for all possible situations. However, it is possible to offer a set of guidelines to be considered in every potential situation.

An independent assessment of the life cycle cost for various low slope roof systems revealed that steel roofing had the longest life span, no leaks due to material failures, and the lowest overall maintenance cost.

This new 120,000 square foot, state-of-the-art convening center features a 1,000-seat auditorium that is large enough to host the entire MBA class. The glass atrium floods the multi-purpose lobby with natural light, as well as provides a visual connection between the interior of the building and the outdoor environment. To maximize transparency, SAFTI FIRST® met with the architects during the design phase to create a large, 2-hour, glass wall that separates the lobby from the auditorium while providing a visual connection between them. Since this 2-hour glass wall also serves as the entrance to the auditorium, deciding on a 90-minute door system was of upmost important. SAFTI FIRST®’s in-house engineering department provided design assistance, system details, engineering calculations and support from the planning phase all the way to the submittal process.

Start at the foundation where the loads imposed by a steel frame are up to 50% less than those of a concrete alternative. There is evidence in the field and through third-party case studies and comparative cost studies that steel building systems offer significant cost benefits over competitive building materials when the total cost of construction is considered.

Because the Sapphire Towers' south facing elevation was in close proximity to the adjacent property, code regulations required the south façade to either be solid, which was contrary to the design, or to have openings with a minimum fire protection of 45 minutes. SAFTI FIRST® engineered a system that met the uniform design demands and performance requirements for the windows and balconies in all 32 floors in the south-facing elevation.

When the people of Canada’s capital region seek relief from city life, they often retreat to the serene, natural beauty found in Quebec’s Gatineau hills. Here, where temperatures can drop to -38°F (-39°C) and snow falls seven months out of the year, heated flooring is a practical luxury. To help recreate a Scandinavian-style getaway for the Groupe Nordik Lofts du Village project, specifiers chose one of MAPEI’s Mapeheat floor-heating systems.

The David Eccles School of Business on the University of Utah campus features a 28- x 18-ft 2 hour interior glass wall with a 90 minute full-vision door in an exit enclosure/stairwell. The architects selected fire rated glass to meet fire rating requirements while providing maximum visibility and natural daylighting in the space. The project’s specifications also required the fire rated glass to have the same optical clarity as the adjacent non-rated glass systems.

Codes required fire wall separations between parking garages and businesses, markets, homes and other uses. Architects can replace entire walls with glass to open up buildings like never before. For example, SuperLite® II-XL in GPX® Architectural Series Framing by SAFTI FIRST® is a USA-made fire resistive transparent wall system that blocks radiant heat and meets the same stringent ASTM E-119/ UL 263/ NFPA 251 code requirements that any opaque fire rated wall must meet.
