The company plans to use the funds to improve its automation and manufacturing technology and speed up the launch of a pilot plant.

V-Glass is building a manufacturing platform to produce vacuum-insulated glass (VIG) at low cost with much better thermal performance. The company says its VIG products can be two to three times more efficient than ENERGY STAR-rated windows, last twice as long, and be made at a similar cost to current options.

“Windows are the biggest source of heat loss in buildings, making up just 8% of surface area but 45% of thermal energy loss,” said Mike Petit, Co-Founder and CEO of V-Glass. “While high-efficiency glass like triple panes and first generation VIGs have existed for decades, they’re too expensive for widespread use. Affordable, ultra-efficient V-Glass changes that, offering strong financial returns for building owners and homeowners.”

“We’ve evaluated many building technologies and believe V-Glass is a breakthrough for both energy efficiency and cost,” said Josh Agenbroad of the Grantham Foundation. “Their glass not only saves energy but also sets a new environmental standard with 100% recyclability, and non-toxic materials—clear advantages over existing solutions.”

The company also noted its 15-year collaboration with the Department of Energy and national laboratories, which provided technical support and non-dilutive funding. More recently, V-Glass won its first contract with the U.S. Army Engineer Research and Development Centre.

V-Glass seeks to close the cost-performance gap by offering glass that is affordable, more energy-efficient, and sustainable. Its technology uses non-toxic, fully recyclable materials, making it an eco-friendly alternative to traditional glass.

The company is tackling a key inefficiency in buildings: windows account for a large share of heat loss. Although high-efficiency glass, such as triple-pane windows and early VIG products, has been around for years, its high cost has kept it from widespread use.

About V-Glass

Founded in 2008 by Peter Petit and Michael Petit, V-Glass has created a next-generation platform for producing vacuum-insulated glass (VIG) that offers 2–3 times the thermal performance of ENERGY STAR® windows, lasts twice as long, and costs the same to manufacture.
