In terms of sheer visual appeal, the three-storey addition to Mandeville High School in Louisiana is a prime example of the ability of Kingspan's Designwall Insulated Metal Panels to create a bold look with custom colours, while inte- grating into translucent glazing (the Designwall 2000 architectural panels used for the project not only enhance creative freedom, with horizontal and verti- cal application capability, they also provide maximum thermal efficiency while creating a double barrier against air and water penetration). North Carolina-based Nucor Corporation bills itself as "North America's most sustainable steel and steel products company," and as such it continues to pur- sue carbon reduction goals (it already has a carbon intensity less than one-third of today's steel mill average globally), and it continues to make advancements in steel products, the latest of which, Elcyon, is the world's first sustainable steel plate for offshore wind projects (it has a recycled content in excess of 90 percent and is produced with ¹⁄5 the global blast furnace average for greenhouse gas emissions). With regard to Nucor Corporation's heavy involvement in building construc- tion, Adam Scott, senior district sales manager at Nucor Buildings Group, says, "While we're known for contributing to large-scale projects with large amounts of metal roofing and cladding, we love to fit in smaller projects too. One of our more fortunate strategies in recent years was to acquire two valued insulated metal panel legacy brands, CENTRIA and Metl-Span, which provide a full range of products to service high-end architectural applications in the cold storage and warehousing realms. Specifically, this enabled us to serve the quickly grow- ing non-residential insulated metal panel category." Scott says that a new elevated roof insulation system, R-Boost, "is being used in a variety of projects, and the feedback we're getting is that it is very easy to install. Equally important, this is a high R value solution to projects that must meet stringent energy efficiency codes." R-Boost's unique patent-pending design features a bridge between an ini- tial and secondary layer of blanket insulation, doubling the insulation capacity and meeting energy codes throughout North America. With the Nucor CFR roof panel, R-Boost can realize U-factors as low as 0.026, which in the US meets the requirements of IECC 2018 (Climate Zones 1-8) and ASHR AE 90.1-2016 (Climate Zones 1-8). Moreover, it is designed to work with Nucor Buildings Group's SS360 roof system. Both the CFR and SS360 panels are well known for their perfor- mance, strength, and weather tightness. Nucor CFR and SS360 panels have been tested and approved by Factory Mutual and Underwriters Laboratories for wind uplift as well as hail and fire resistance, and when used in combination with R-Boost, this system provides the highest potential for total building system cost savings (plus, on average, R-Boost installation costs are considerably lower than that of competing systems). Companies specializing in metal products and components continue to evolve in 2023. Cascadia Metals, the premium metal distributor of coil and sheet prod- ucts, announced earlier this year that it is now manufacturing a new line of products at its Tubular Division in Brandon. All told, Cascadia's output in addi- tion to coil and sheet metal includes HSS tubing, merchant bar, rebar, expanded metal, wide flange beam, galvanized fence pipe, and UL/FM rated sprinkler pipe. But Cascadia's pre-painted PVDF (polyvinylidene fluoride) steel products are of special interest to architects. Available in coil and flat sheet, these products are galvanized and 55 percent aluminum-zinc alloy coated substrates and come in a variety of popular colours, fully supported by industry competitive warranties. PVDF is a highly non-reactive and pure thermoplastic fluoropolymer used in a variety of applications where the highest purity, strength, and resistance Nucor CFR roof panels, Aerocentre 2, Edmonton, AB.
