Which Fire-Rated Glass Cuts Carbon Without Compromising Safety?

This week’s quiz is from Igniting change: Sustainable fire-resistive glazing. Architects have long relied on fire-rated glass to protect building occupants—but the materials themselves often carry a hefty environmental cost. From wired glass to ceramic glazing, each evolution balanced safety with design constraints. Now, a next-generation intumescent glazing promises the same—or even better—fire protection with up to 35 per cent less embodied carbon. Can you identify this transformative solution that’s changing both fire safety and building sustainability?
