Glass block has long been celebrated for its ability to blend privacy, light transmission, and timeless design—but performance standards are evolving. GBA’s newly released DuraTherm Energy Block meets this evolution head-on. Engineered for high-demand environments, it delivers the rare combination of exceptional strength and advanced energy efficiency—without compromising aesthetics.
Whether you're designing for a school, a transit facility, or a commercial project in a hurricane zone, the DuraTherm Energy Block offers a forward-thinking solution. It reflects GBA’s ongoing commitment to solving real-world architectural challenges with innovation that’s practical, code-compliant, and visually refined.
The DuraTherm Energy Block is built for today’s energy codes and tomorrow’s design challenges. It delivers reliable thermal insulation and serious structural strength—without compromise.
The DuraTherm Energy Block was born from industry demand. As building codes tightened and energy efficiency became essential, GBA saw a gap: the market needed a block that could deliver strength and insulation without compromise.
With decades of experience—including large-scale installations for the NYC School Construction Authority and MTA—GBA knew what was at stake. Their past products prioritized security and durability. Now, DuraTherm brings those same qualities together with energy savings, low maintenance, and natural light—all in one smart solution.
Performance is critical—but so is design flexibility. The DuraTherm Energy Block offers both. With multiple pattern and finish options—including Nubio, Clarity, and Endura—this block adapts easily to different aesthetic goals while maintaining high performance across all variants.
And installation? GBA ensured the process remains familiar for architects and contractors. Despite its increased thickness (4"), DuraTherm installs much like other glass block systems—with one key advantage: it can handle larger openings (up to 144 square feet) without requiring structural steel. That simplifies the design process and reduces material and labor costs.
With the launch of the DuraTherm Energy Block, GBA is setting a new benchmark for glass block innovation—one that meets the realities of today’s building environment without sacrificing the qualities designers value most: clarity, durability, and ease of use.
From energy efficiency to impact resistance, this block is built to perform where it matters most—schools, transit hubs, hurricane zones, and beyond. It's not just an upgrade; it’s a smart solution for building professionals who demand more from their materials.
