Ypsilanti, Michigan — March 26, 2026 — LuxWall, the pioneer in Transparent Insulation, today announced that Enthermal™ has received a third-party verified Environmental Product Declaration (EPD), providing architects, building owners, developers, and policymakers with standardized data on the product’s environmental impact across its full lifecycle.
At a time when buildings account for nearly 40% of global energy consumption and related carbon emissions, the industry is facing increasing pressure to quantify performance. LuxWall’s EPD introduces product-level transparency to the building envelope, particularly in the window system, where conventional performance metrics have not fully captured real-world energy impact.
“Buildings are one of the largest and most overlooked sources of energy waste globally, and windows are at the center of that problem,” said Scott Thomsen, founder and CEO of LuxWall. “For decades, the industry has accepted that better windows meant more material, more layers, and more carbon. This EPD marks a shift toward accountability, enabling stakeholders to evaluate Transparent Insulation as a new category of building envelope solutions designed to perform like see-through walls rather than traditional glazing, at a lower carbon footprint.”
The EPD, developed in accordance with EN 15804 + A2 and ISO 14025 standards and independently verified by EPD Hub, evaluates Enthermal’s environmental impact across its full lifecycle from raw material extraction through manufacturing, installation, use, and end-of-life.
Key findings from the EPD include:
- Full lifecycle carbon footprint: 44.6 kg CO₂e per m² (4.1 kg CO₂e per ft²)
- Cradle-to-gate carbon footprint: 38.4 kg CO₂e per m² (3.6 kg CO₂e per ft²) compared to published EPD values of 54.3 kg CO₂e per m² (5.0 kg CO₂e per ft²) for a tempered or heat strengthened double-pane IGU and 93.9 kg CO₂e per m² (8.7 kg CO₂e per ft²) for a tempered or heat strengthened triple-pane IGU
- Manufacturing powered by renewable energy: 100% of electricity consumption at LuxWall’s Michigan facility is matched with renewable energy certificates
Unlike traditional insulating glass units, which rely heavily on thicker assemblies and gas fills, Enthermal achieves superior performance through its vacuum insulation technology that virtually eliminates conductive and convective heat transfer, transforming windows from an energy liability into a high-performance building asset.
As embodied carbon regulations and disclosure requirements advance worldwide, the need for verified, product-level environmental data has become increasingly critical for developers and asset owners. The addition of an EPD enables Enthermal to support compliance with leading certification frameworks, including LEED, BREEAM, and WELL.
Windows have long been the weakest points in the building envelope, responsible for significant heat loss and energy inefficiency. LuxWall’s Transparent Insulation addresses this challenge directly, enabling retrofit and new construction projects to achieve step-change improvements in energy performance without sacrificing design.
As the industry continues to prioritize environmental initiatives and grid resilience, reducing energy demand at the building envelope level becomes a way to free up capacity on the grid, enabling that energy to be redirected to more critical infrastructure.
