50 Years of Window Innovation featuring Stephen Selkowitz

How far can window performance really go - and what’s holding the industry back from scaling better solutions? In this episode of All Things Facades Podcast, Stephen reflects on more than 50 years of innovation in window and façade technology. From the early research following the 1970s energy crisis to the development of low-E coatings, triple glazing, and vacuum-insulated glass, the conversation traces how performance improvements have shaped modern glazing systems. The discussion explores the practical limits of increasing insulation and why attention is shifting toward managing solar heat gain, glare, and daylight while maintaining occupant comfort and views. It also examines the real-world challenges of scaling new technologies, including supply chain constraints, manufacturer risk, and the complexity of commercial façade systems. The episode highlights the role of energy codes, pilot programs, incentives, and industry collaboration in helping proven technologies move from research into widespread market adoption. #AllThingsFacades #LawrenceBerkeleyLab #FacadeEngineering #BuildingScience #HighPerformanceWindows #LowEGlass #TripleGlazing #VacuumInsulatedGlass #EnergyCodes #GlazingTechnology #EnergyEfficiency allthingsfacadesgroup.com
