Curved Glass: An Industry Perspective

In this video, Ferran Figuerola, a third-generation leader of the nearly century-old family business Cricursa, traces curved glass from its traditional flat origins to its role in ambitious architectural facades. Curved glass is unique because it adapts to complex geometries, becoming exceptionally stiff and capable of resisting wind loads while offering dynamic light effects that change with the angle of light. Key challenges center on both manufacturing and logistics. The process requires specialized ovens, careful heat treatment choices, and precise molding or quenching techniques. Installing curved glass is trickier than flat glass because its three-dimensional shape demands specialized equipment and careful prediction of how the glass will behave when lifted or inclined. Beyond production, storing and shipping these unstable curved forms adds further difficulty. Figuerola emphasizes that despite nearly a century of shared experience, every day brings new learning opportunities and challenges. He explains how to anticipate unpredictable costs by accounting for risks and uncertainties in production. In extreme cases, five production attempts may yield solely one success. Yet surprises can go both ways: a complex glass ladder and slide created for Glasstec in Düsseldorf succeeded on the very first try, defying his own cautious expectations. The video was produced by the Open GLASSroom project. Special thanks to Ferran Figuerola and Cricursa for contributing to the Open GLASSroom OER collection.

The Origins of Structural Gass design

In this video, Tim Macfarlane, a structural engineer in London, traces structural glass from its hesitant beginnings in 1989 to its role in contemporary architecture. Glass is unique not because it is new, but because of its magical simplicity: a thin sheet that keeps weather out while connecting inside to outside. Through constant innovation, glass has undergone numerous processes such as lamination, toughening, or coatings that, while improving performance, also reduce reusability and raise environmental questions about whether large, complex glass is truly sensible. Early projects with architects Eva Jiřičná and Rick Mather forced Tim to question fundamental issues the industry had not addressed: how strong glass really is, how to calculate it, and how to make it safe, information once treated as private intellectual property. His role became one of moral integrity, negotiating between market pressures and client ambitions. Tim advises young engineers to keep an open mind, love life, and have fun with curiosity. True intelligence comes from within, not from AI. The journey of asking questions and fulfilling yourself as a human being is what matters. The video was produced by the Open GLASSroom project.

3D Printed Glass Fabrication and Applications

In this video, Michael Stern, artist, engineer, scientist, designer, and co-inventor of molten glass 3D printing, traces glass fabrication from traditional blowing to additive manufacturing. He shares how he first encountered glass, what drew him to 3D printing, and how his parallel passions for mechanical engineering and glassblowing eventually converged into the invention of a new process. The 3D printing process involves a printer that works by heating a crucible of molten glass, which flows through a nozzle while a build plate moves layer by layer. The object is typically built over the course of 20 minutes to two hours, depending on its size. Rather than forcing the material, Stern emphasizes that working with glass requires listening to it, as it is a "loud material" with its own opinions. He advises those learning and working with glass to break challenges into small, unremarkable steps, given that innovation is simply the result of adding those steps together over time.

Kwalitatief onderzoek hergebruik open leermaterialen

In opdracht van de Content Advies Raad, onderdeel van Npuls, is een kwalitatief onderzoek uitgezet onder vakcommunities die leermaterialen delen in collecties. Omdat veel materialen open worden gedeeld, maar nog weinig worden hergebruikt, is er onderzoek gedaan naar de reden waarom docenten wel of niet overgaan om open leermaterialen te gebruiken of aan te passen. Het onderzoek is uitgevoerd door Harry Stokhof en Roel Grol (HAN), in samenwerking met Sylvia Moes, Tineke van Maanen en Anders Kropveld.

Understanding Glass Codes and Standards

In this video, Martina Eliášová outlines the critical role of codes and standards in the use of structural glass in modern architecture. As glass evolves from a simple infill material to a primary structural element in beams, columns, and load-bearing walls, ensuring safety becomes paramount. The framework has evolved from national standards to unified European Eurocodes, which harmonize design, manufacturing, and testing rules across the EU to ensure quality and safety. The key groups of standards cover glass production, material property determination (e.g., EN 1288, EN 16612), and the design of load-bearing structures (with the upcoming EN 19100). Essential testing standards are also outlined, including those for impact resistance from human bodies (EN 12600), manual burglary attacks (EN 356), and resistance to firearms and explosions, all necessary to meet the reliability and safety requirements for building structures throughout their service life. The video was produced by the Open GLASSroom project. Special thanks to Martina Eliášová for contributing to the Open GLASSroom OER collection.

Water-Filled Glass as a Heat Displacement System for Saving Energy in Buildings

In this recorded presentation from glasstec 2024, Brandon Mok introduces Water-filled Glass (WFG), a technology that replaces the gas in an Insulating Glass Unit (IGU) with a water layer connected to a mechanical system with a heat exchanger and pump. The core function is to manage a building's energy demand by controlling the water temperature to optimize the glass surface temperature, thereby reducing the need for mechanical heating and cooling. Studies show WFG can provide 47-72% better energy savings than double glazing and 34-61% better than triple glazing. The presentation further explores a novel concept called SEED (Saving Energy through Energy Distribution), which uses the WFG system to redistribute heat from building facades requiring cooling to those requiring heating simultaneously. A preliminary simulation for office buildings in London and New York showed that WFG alone achieved 58-72% energy savings, with the SEED concept providing an additional 10-13% in savings by balancing energy demands across different orientations.

Fire Resistant Glass

In this video, Aleksandra Sweryn explains the critical role of fire-resistant glass in building safety, particularly for compartmentalization in public spaces. Standard glass products like insulating or laminated units offer little fire protection, as they break quickly and can contribute to fire spread. In contrast, specialized fire-resistant glass, such as AGC's Pyropane (tempered with low-E coating) and Pyrobel (with intumescent gel), is designed to withstand high temperatures. These products work by reflecting radiant heat or by having the gel expand to form an insulating foam that blocks heat transfer. To be certified, glazing must pass rigorous standard tests (like EN1363/4) to achieve fire-resistance ratings (E, EW, EI) based on integrity and insulation performance, with even small changes in the gel's composition significantly impacting its effectiveness. The video was produced by the Open GLASSroom project. Special thanks to Aleksandra Sweryn for contributing to the Open GLASSroom OER collection.
