LuxWall has closed a $51 million Series B funding round led by Climate Investment and Barclays Sustainable Impact Capital. New investors Carbon Equity and The Nature Conservancy participated in the round alongside existing investors Breakthrough Energy Ventures, Prelude Ventures, 2150, Khosla Ventures and Baruch Future Ventures.
The recent funding allows LuxWall to scale up production at its newly opened factory in Litchfield, Michigan, which received the support from Michigan Governor Gretchen Whitmer. It will also enable the construction and expansion of a second factory in Detroit, Michigan, as well as the growth of research and development at the R&D Center in Ypsilanti, Michigan. Alongside this Series B funding, LuxWall received a $31.7 million U.S. Department of Energy Manufacturing Efficiency and Supply Chain grant to support the Detroit facility.
Why this funding is needed
Windows are the single largest source of energy loss in the built environment, which represents 38% of the world’s greenhouse gas emissions. LuxWall has developed patented technologies to manufacture vacuum insulating glass with thermal insulating properties like an opaque wall, five times more insulating than double-paned glass. LuxWall’s Enthermal product line reduces energy loss of homes and buildings by up to 45%, with three times faster payback versus standard glass offerings. Enthermal can be retrofit into existing window frames, which reduces re-glazing costs by up to 50% for end users.
Servicing residential homes, historic sites and commercial buildings across North America and Europe, LuxWall’s high-performance window solutions have been adopted by large corporates operating in a range of sectors, including manufacturing, technology and residential.
The U.S. Department of Energy selected LuxWall as one of seven U.S. companies to receive funding to strengthen clean energy supply chains and accelerate domestic clean energy manufacturing. LuxWall has been recognized for the value of its technology, having been included in the Norrsken Foundation’s 2024 Impact/100 list of the world’s most promising impact startups, as one of just three startups in the construction sector.
What people are saying
“This funding is a major vote of confidence in LuxWall, and we welcome the support of new decarbonization and impact-focused investors, along with our existing backers,” says Scott Thomsen, CEO and co-founder, LuxWall. “LuxWall is fortunate to have such a strong investor syndicate to propel our vision of Bettering the Built Environment.”
“Climate investment invests in innovators decarbonizing the built environment and we are excited to be adding LuxWall and its best-in-class team and technologies to this group,” says Cindi Bough, managing director climate investment. “With 50% of building stock still single-pane windows, and 25% of the energy used to heat and cool them are lost through windows, the market opportunity for LuxWall is massive, and LuxWall technology is primed to help significantly reduce carbon emissions from the built environment.”
“As a cost-effective retrofit to replace single-pane glass, LuxWall’s remarkably thin, high-performing glass could transform residential and commercial building stock across the world. With a unique offering to such a large market, LuxWall has huge commercial potential, and can play a particularly important role in retrofitting properties that until now have had very limited economically attractive options for improving the performance of the building envelope,” says Steven Poulter, head of principal structuring and investments.
“Building and construction markets account for 40% of global GHG emissions. LuxWall’s innovative insulating window solutions will help us achieve equitable justice to occupants of new and retrofitted dwellings and offices and mitigate the shocking increases in electricity prices between 2021 and 2024 from surging power demand in industrial and information technology sectors of the economy,” says Tom Baruch, CEO, Baruch Future Ventures LLC.
