LuxWall has announced that its Enthermal product has received a third-party verified Environmental Product Declaration (EPD), marking a significant step toward greater transparency in building materials and performance.

As buildings account for nearly 40% of global energy consumption and related carbon emissions, the construction sector faces increasing pressure to quantify and reduce environmental impact. The newly issued EPD provides architects, developers, and policymakers with standardized lifecycle environmental data.

According to CEO Scott Thomsen, the certification represents a shift in how the industry approaches window performance, moving toward lower-carbon, high-performance alternatives rather than material-heavy solutions.

The EPD was developed in accordance with EN 15804 + A2 and ISO 14025 standards and independently verified by EPD Hub. It evaluates Enthermal’s impact across its full lifecycle – from raw material extraction to end-of-life.

Key findings highlight Enthermal’s competitive environmental performance. The full lifecycle carbon footprint is 44.6 kg CO₂e per m², while the cradle-to-gate footprint is 38.4 kg CO₂e per m², both notably lower than conventional double- and triple-pane insulating glass units.

Additionally, LuxWall reports that 100% of electricity consumption at its Michigan manufacturing facility is matched with renewable energy certificates.

Unlike traditional insulating glass units, Enthermal uses vacuum insulation technology that significantly reduces conductive and convective heat transfer. This allows windows to perform more like insulated walls, improving building efficiency without compromising transparency.

The EPD also supports compliance with major certification frameworks such as LEED, BREEAM, and WELL, where verified environmental data is increasingly required.

As embodied carbon regulations evolve globally, solutions like Enthermal address one of the building envelope’s weakest points – windows – by enabling significant reductions in heat loss and energy demand in both retrofit and new construction projects.
