Hradec Králové / Prague, May 5, 2026 – Czech technology company VoltGlass s.r.o. has taken the first step toward entering the American market. Its patented heated glass technology has been included in the offering of American licensing platform IPOfferings. The company announced today that it wants to use the platform to reach window manufacturers, construction companies, and heating system suppliers in the United States.
About VoltGlass Technology
VoltGlass is an innovative building heating system integrated directly into the window pane. Glass coated with a layer of conductive metal oxide transmits sunlight just like conventional glass, but simultaneously serves as a heating panel – when connected to the electrical grid, the glass heats evenly up to 50°C and radiates heat throughout the interior.
The system is designed as insulating double/triple glazing with inert gas between panes. Electric current flows exclusively on the interior surface of the inner glass, posing no risk to users. Windows don't fog (no condensation) and are completely safe.
Breakthrough Concept: 2 in 1 – Window as Heating Element
Windows are traditionally seen primarily as places of heat loss in buildings. VoltGlass changes this principle: the window area can instead become an active heating element. The technology can eliminate the need for conventional radiators under windows, improve space utilization, and open new possibilities in interior design and building technical equipment.
Thanks to radiant heat transfer, the system can contribute to higher thermal comfort even at lower room air temperatures. Applications can be found in family homes, office buildings, schools, public buildings, production halls, or shopping centers.
Strong Patent Protection
VoltGlass technology is protected by Czech patent CZ 309675/2023 and European patent. The American patent application US 20250324490 for the invention named "Heating glass and glass filling of a window structure comprising the heating glass" aims to protect the technology in the US market. IPOfferings platform offers it as a licensing opportunity for window manufacturers and heating system suppliers in the US.
"The American market is a crucial milestone for us. Including VoltGlass technology in IPOfferings' offering opens the way to licensing or strategic partners who can make an innovation developed in the Czech Republic an available solution for modern buildings. We want to establish a new generation of windows on this key market – windows that won't be just a passive part of the building, but an active heating element – elegant, energy-efficient, and space-saving."
