"changing room"

As part of Conestoga College’s campus expansion, several new rooms and spaces required acoustic solutions to enhance quietness for the large student population. The Brantford and College 1 Young buildings were particularly in need of such materials. Hush Acoustics collaborated with the college to provide innovative acoustic products for these areas, effectively addressing their specific needs.

The Joint School of Nanoscience & Nanoengineering within the Gateway University Research Park in Greensboro, North Carolina is a new 105,000 sf interdisciplinary research facility dedicated to academic and industrial research. To create an open, transparent lab design, SAFTI FIRST® provided SuperLite® II-XL 60 in GPX® Architectural Series Frames for the 60 minute walls.

Global warming and climate change are two terms found increasingly in headlines around the world. Initiatives such as the Kyoto Protocol have brought these issues to the forefront and provide a framework and objectives for reducing greenhouse gases (GHG). GHG are heat trapping gases, such as water vapour, carbon dioxide, or methane that absorb the earth’s heat and hinder it from being released into space. As levels of GHG build up in the atmosphere, a greenhouse effect takes place that warms the earth’s atmosphere and makes global climate change inevitable. A?itudes on environmental issues are changing worldwide. Developed nations are commi?ing to reducing GHG emissions to 5.2% below the 1990 baseline by 2012. Notably, Canada has commi?ed to reducing its GHG emissions to 6% below 1990 levels, which corresponds to a gap of 29.1% of where the nation is and where it wants to be. An ambitious undertaking, considering that Canada’s GHG emissions have been steadily on the rise over the years and in 2004 was actually 26.6% higher than 1990 levels. On a positive note, in the last two years emissions have started to decline, but there remains a long way still to go. =e quest for a greener Canada continues and helping to lead the way to a greener Canada is the nation’s steel industry, which is making great strides in reducing GHG emissions, conserving energy, and lessening impacts on our air, water, and land.

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.

Rose Rocket, a Canadian software company, established their head office in the heart of downtown Toronto in 2020. They chose a heritage site featuring a three-story atrium surrounded by a ‘U’-shaped office space. Ray Architecture Studio partnered with Hush Acoustics to bring their interior design vision to life, which included smaller meeting rooms, larger boardrooms, and an open office concept.

Central to the building's design are several simulation labs, practice labs, and mock operating rooms where students can observe instructors and each other as they perform their tasks. Because these labs are in areas where a 1-hour fire rating has to be maintained, the architects chose to combine vision, transparency, and fire safety with SuperLite® II-XL 60 in GPX® Architectural Series framing.

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

Central to the new UC Davis Medical Center Surgery and Emergency Services Pavilion's design was a large skylight that allows natural light to vertically flow into the atrium area and other light wells throughout the building. However, they also wanted to let light flow horizontally into the adjacent hallways, rooms, etc. Because the walls in the atrium and light wells have to meet a 2-hour rating, Stantec Architects approached SAFTI FIRST® for a solution. Large portions of the 2 hour atrium and light well walls were made “transparent” with the use of SuperLite® II-XL 120 in GPX® Framing.

About the ProjectThe Qatar National Library covers over 42,000 sq. metres and houses millions of books, e-books, historic texts, manuscripts, periodicals and more. The entire building has been envisioned to look like a single room with clear views of the surrounding areas. Tying into the entire project’s overarching theme, the architect designed the building to resemble a diamond. A sunken patio in the heart of the building provides light to the office spaces while also serving as a transition space between the harsh outdoors and the sanctuary of books inside.The ChallengeThe customer’s vision for the library required panels that offered clear views with minimal to no reflection.

IntroductionSheet Steel Roong and SidingLightweight Steel FramingIsolate the Steel and Wood ComponentsAvoid Use of Pressure Treated WoodFastenersMany buildings will include wood members in applicationssuch as sill plates, splash boards, strapping, purlins, door orwindow bucks, and posts. In some of these end-uses it is arequirement that the wood be chemically treated (pressuretreated) to extend the service life.Designers and builders need to be aware that changes in theavailable wood perservatives may impact the durability ofany connected steel components or fasteners.Eective January 1, 2004 the Environmental ProtectionAgency (EPA) banned the use of Chromated CopperArsenate (CCA) as a preservative in treated lumber forresidential construction. This was done in an eort to reducethe use of chromate and arsenic thereby mitigating thepotential health and environmental problems. The woodpreservative industry has been switching to alternativewaterborne compounds including Sodium Borate (SBX),Alkaline Copper Quat (ACQ), Copper Azole (CBA-A and CA-B),and Ammoniacal Copper Zinc Arsenate (ACZA).Unfortunately, research has indicated that ACQ, CBA-A, CA-Band ACZA, the new generation copper-based products, aremore corrosive to galvanized steel than the former CCA.Since ACQ is becoming the predominant preservative in use,the discussions in this paper will refer to it exclusively.The purpose of this Fact Sheet is to convey the recommendations of the sheet steel industry for the application of steelproducts with ACQ pressure treated wood.

Steel: unparalleled fire safety Life safety, and specifically fire protection, has been a primary concern of the building codes. Steel is a non-combustible material and consequently does not burn, provide an ignition source or add fuel load that would enable a fire to spread or grow into a catastrophic event. Steel does not melt at temperatures typically encountered in a building fire. Its non-combustibility and assembly fire ratings do not degrade over the lifecycle of a building. This provides a reduced fire risk, to workers and occupants, minimizes the impact on municipal fire services, decreases the reliance on sprinklers, and results in less property damage and collateral damage to adjacent buildings if a fire should ever occur. • Steel has a melting point of approximately 1,500ºC (2,700ºF). In a typical fire, such as in an office, residential or retail occupancy, the maximum temperature of a fully developed fire will not likely exceed a range of 800ºC to 900ºC (1,500ºF to 1,650ºF), though it could reach a peak of 1,100ºC (2,000ºF) for a short duration. • Building codes recognize the fact that buildings, designed with non-combustible materials like steel, pose less of a fire risk to the public than combustible systems, which are limited to six storeys in height in Canada and 25.9m (85 ft.) in the US. STEEL IS A NON-COMBUSTIBLE MATERIAL AND CONSEQUENTLY DOES NOT BURN, nor does it provide an ignition source or add fuel load that would enable a fire to spread or grow into a catastrophic event. “Changes in the building codes that allow combustible framing in taller and larger buildings have gone too far and it’s created a perfect storm that can quickly overwhelm the ability of the fire service to respond.” CHIEF STEVE LOHR, HAGERSTOWN (MD) FIRE DEPARTMENT

Executive Summary The aim of this fact sheet is to advocate an alternative solution for the Steel Industry in regards to restrictive code provisions for explosion venting that are now mandated by the Ontario Fire Code (OFC). Due to a September 2000 amendment of code provisions dealing with explosion venting in the OFC, explosion vent designs were required to be in conformance with NFPA 68, the National Fire Protection Association’s (NFPA) Guide for Venting of Deflagrations. NFPA 68 gives a prescriptive solution that has upper bound limits on size and mass of an explosion vent panel, which the Steel Industry finds are too small to be practical. The Canadian Steel Construction Council (CSCC) investigated this problem and identified an alternate design guideline from the Factory Mutual Insurance Company’s (FM) Property Loss Prevention Data Sheets, numbered 1-44 and entitled “Damage Limiting Construction”. FM’s 1-44 Data Sheets can be used to develop an alternate solution for explosion venting that exceed the size and mass limits of the NFPA 68 prescriptive solution, and can be submitted for approval under the Compliance Equivalency provisions in the OFC. With the introduction of an objective based National Building Code Canada (NBCC) in 2005 followed by Provincial code adoptions in 2006 it would be worthwhile to establish a precedent through the Compliance Equivalency provision in the OFC. Once a precedent setting case occurs, the “acceptable solution” or “compliance alternative” would go on record and aid in resolving subsequent proposals for Compliance Equivalency, and also support a future technical change in the OFC. The CSCC by way of this fact sheet would advocate this alternative solution for the Steel Industry when designing explosion vent panels in steel framed buildings.

OverviewSet in the heart of downtown Toronto, the Ontario Court of Justice is the largest courthouse in Ontario and a benchmark for contemporary institutional construction. Completed in 2024, the project brings together 63 courtrooms and 10 conference settlement rooms in a LEED® Gold certified facility that reflects modern civic values—transparency, accessibility, and sustainability.Master Builders Solutions Canada Inc. played a key role in ensuring the structural concrete met the performance demands of this high-profile project.The ChallengeDelivering nearly 48,000 m³ of ready-mixed concrete in a downtown location posed numerous technical challenges. The structural design demanded high compressive strength, consistent workability, and durability to support complex load paths, security zones, and a tall atrium enclosed by a 20-metre glass façade.The project team required concrete solutions that would:Maintain workability over long pumping distances and vertical placements,Ensure strength development for critical structural zones (such as core walls and transfer slabs),Limit thermal cracking during curing in massive pours,Integrate seamlessly with staged slipform and rebar installation schedules.These demands were intensified by the need to meet LEED® Gold sustainability targets, tight construction timelines, and high public visibility.The ResultsMaster Builders Solutions Canada Inc. partnered closely with St Marys CBM to optimize concrete performance across all phases of construction. A suite of high-performance admixtures—including water reducers, retarders, and strength-enhancing additives—was deployed to address the project’s structural and logistical complexities.Key contributions included:Enhanced workability retention for long-distance pumping and complex placements, reducing placement time and labour.Improved early- and long-term strength development, enabling faster formwork cycling and reliable performance in high-load areas.Mitigated thermal buildup in mass pours to control cracking and ensure durability over the structure’s lifecycle.Admixture compatibility with supplementary cementitious materials (SCMs), aligning with the project’s environmental goals.By tailoring admixture solutions to the precise performance needs of each mix design, Master Builders Solutions supported consistent quality and efficiency throughout the build.The Ontario Court of Justice now stands not only as a civic institution but also as a demonstration of what is possible when modern structural design and advanced concrete technology are brought together. The project exemplifies how Master Builders Solutions helps construction teams deliver on performance, sustainability, and long-term value.
