LuxWall 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.
“Buildings are one of the largest and most overlooked sources of energy waste globally, and windows are at the center of that problem,” says 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.”
EPD findings
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: 4.1 kg CO₂e per square feet.
- Cradle-to-gate carbon footprint: 3.6 kg CO₂e per square feet compared to published EPD values of 5.0 kg CO₂e per square feet for a tempered or heat strengthened double-pane IGU and 8.7 kg CO₂e per square feet 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.
The addition of an EPD enables Enthermal to support compliance with leading certification frameworks, including LEED, BREEAM, and WELL.
