FGIA Issues New Guidance on Designing High-Performance Multiple-Cavity IGUs

USGlass Magazine•February 05, 2026•1 min read

, “Design Considerations for Multiple-Cavity Insulating Glass Units,” was last updated in 2013. The document aims to guide the design, fabrication and use of multiple-cavity IGUs within the fenestration industry.

“Demand for increasing energy-efficient fenestration products continues to rise,” says Amy Becker, FGIA glass products specialist and staff liaison for the Design Considerations for Multiple Cavity IGUs Task Group. “One method for addressing this demand is by increasing the number of cavities in an IGU. This method, while effective, can create new challenges. These guidelines are therefore intended to assist those who design, specify, fabricate and install units.”

Defunct Glass Company Still on the Hook for $1.6M Pension Bill, Court Says

A bankruptcy bid by a defunct glass company to avoid paying the International Union of Painters and Allied Trades (IUPAT) Pension Plan around $1.6 million was rejected by a United States Court of Appeals Fourth Circuit panel. According to Judge James Harvie Wilkinson III, Florida Glass of Tampa Bay Inc., which dissolved in 2017, sought to “use a quirk of bankruptcy law to avoid paying what it owes [to] a multi-employer pension plan.” IUPAT initially filed the lawsuit in 2023 after it sent a formal notice and demand in 2022 for $1.577 million of withdrawal liability. IUPAT’s pension fund is a multiemployer pension plan regulated by ERISA and the Multiemployer Pension Plan Amendments Act of 1980 (MPPAA). While Florida Glass did not fight the amount, it argued that the suit was filed too late, extending past the six-year statute of limitations after IUPAT’s pension fund filed a claim in 2016. A lower court previously rejected Florida Glass’ statute of limitations defense. The Fourth Circu

FreMarq, Alpen Target Whole-Assembly Energy Efficiency with Thin Glass Technology

FreMarq Innovations announced a partnership with Alpen to assist Alpen’s thin glass technology within FreMarq’s Zero•Net curtainwall framing systems. According to FreMarq officials, the combined technologies support up to R-10-level whole-assembly performance. Officials explain that the center-of-glass performance assumptions often fail to reflect how glass performs once installed in a frame, while high performance is frequently viewed as requiring premium systems. As part of the partnership, FreMarq and Alpen aim to improve whole-assembly performance and help energy savings, comfort and return on investment expectations. “High-performance glass delivers its full value only when the frame performs at the same level,” says Renea Frederick, FreMarq president. “By pairing Alpen’s thin glass technology with Zero•Net framing, we improve the performance of the glass at the assembly level. That alignment allows projects to achieve meaningful thermal results and do so at a cost that challenges

Veteran Estimator Darryl Bradshaw Joins Accura Systems

Darryl Bradshaw has joined Accura Systems Inc. as a senior estimator. Bradshaw has been an estimator for Vistawall and Oldcastle BuildingEnvelope Inc. (OBE acquired Vistawall in 2007), where he estimated major projects, including custom-installed skylights “In 1984, a young draftsman walked into my office at Vistawall with a stack of die drawings from Western Extrusion,” says Mike Rubner, Accura president. “He asked, ‘What do you all do here?’ That simple question was the beginning of a long and successful career. He worked ‘on the board’ as a draftsman until 1985, when he moved into CAD. He was quite talented at design and worked his way into a sales and estimating role until about 1991, when he learned to estimate. I couldn’t be happier that he once again asked me, ‘What do you all do here?’ and I said, ‘custom unitized curtainwall. Welcome aboard.’ We at Accura are fortunate to have Bradshaw join our team.”

Vietnam Orders Temporary Tariffs on Imported Float Glass

Vietnam’s Ministry of Industry and Trade will place temporary anti-dumping duties on some colorless float glass products from Indonesia and Malaysia. Ministry officials say that an investigation into dumped imported goods from Indonesia and Malaysia found that the illegal imports have caused significant and evident damage to Vietnam’s glass industry. They note that the volume of imports of the dumped goods has increased by more than 61.8% year-on-year, even after the investigation started. As a result of the findings, the Ministry will apply provisional anti-dumping measures to prevent the rapid increase in imports of colorless float glass from Indonesia and Malaysia. Those measures include anti-dumping duty rates ranging from 15.2% to 63.4%. reports that the tariffs are expected to begin on February 13 and will be in place for 120 days.

Weather Monitoring Platform Communicates Instantly

and have partnered to integrate Perry Weather’s onsite weather monitoring and alerting platform directly with the Eyrus worksite intelligence platform. On a typical job site, weather safety is a manual “game of telephone.” Safety directors often juggle consumer phone apps and radio calls, hoping critical warnings reach the right crews in time. This reliance on distant, generalized weather data is slow and leaves firms exposed to unnecessary liability. This integration eliminates that lag by syncing Perry Weather’s onsite hardware with Eyrus’s workforce intelligence. When onsite sensors detect a threat, such as lightning within 10 miles or a dangerous heat threshold, the system bypasses the manual chain of command to instantly alert every worker currently checked into the site. Construction teams don’t need another generic weather forecast; they need to know exactly when to stop work and, more importantly, when it’s safe to start again. By connecting onsite sensors to Eyrus’s communicat

Parents File Lawsuit Against Window Installer After Child’s Fatal Fall

The parents of a child who fell from a ninth-story window to his death in a Kansas City apartment complex have filed a lawsuit against the glass company that installed the window. According to the , the parents, Destiny Randle and Moses Bass, accuse Crown Diversified Industries Corp. (Crown Window Corp.) of installing a window that “lacked basic fall-protection safety features that would have prevented a child from falling from such a height. These safety measures were well known in the window industry and simple to implement.” Crown Window is a Missouri-based supplier and installer of windows for hospitality, multi-family housing, senior living and student housing projects. Randle and Bass’ son, 3-year-old Tidus, fell nine stories from his bedroom window at the Independence Towers on July 29, 2024.
