Transparent Insulation™ by LuxWall is Scienced with Vacuum Insulation Technology
Enthermal Plus® represents the next generation of high performance residential and commercial glazing. This 1-inch Transparent Insulation unit integrates LuxWall’s vacuum insulation technology with a standard insulating glass unit (IGU) configuration to deliver an exceptional 0.043 U-factor over 5X the insulation of conventional double pane units and 3X the performance of triple pane units. Designed to fit seamlessly into existing 1-inch framing systems, Enthermal Plus requires no redesign or manufacturing changes. The result is dramatically improved energy efficiency, noise reduction, condensation resistance, and year-round occupant comfort while maintaining full compatibility with current window and façade designs.

ENERGY STAR® Certification for Residential Windows
ENERGY STAR® is a program run by the U.S. Environmental Protection Agency (EPA) that promotes energy efficiency in consumer products, including windows. ENERGY STAR 7.0 is the latest version of the ENERGY STAR program’s requirements for windows.
Enthermal Plus products scienced by LuxWall Transparent Insulation™ technology are engineered to deliver exceptional thermal performance across all ENERGY STAR® climate zones —from the coldest northern regions to the hottest southern environments. By combining advanced vacuum insulation technology with high-performance low-emissivity coatings and standard IGU systems, Enthermal Plus minimizes heat transfer while optimizing solar control and daylight transmission.
