We see the way forward – with high-performance window solutions for existing structures to reduce energy consumption and global carbon emissions.


World’s energy consumed by buildings


Global CO2 Greenhouse Gas produced by buildings


Energy loss experienced by building with single pane windows

Windows are the single largest source of energy loss in buildings. To ensure our planet’s survival, the energy efficiency of buildings must improve exponentially.

Our technological advancements in vacuum insulating glass will accelerate us to net zero buildings.

LuxWall Enthermal™ high-performance glass technology significantly reduces building heating costs up to 45% and cooling costs up to 20%. Enthermal™ will change the built environment in the same way wind and solar are changing energy production. With mass adoption, this energy-efficient glass innovation can reduce global carbon emissions by 14%.

R-18 Center of Glass (COG)

Our product innovations, called Enthermal™ and Enthermal Plus™, are designed to reduce energy consumption with high R-value energy-efficient vacuum insulating windows installed in existing buildings and new construction.

Our next generation product solutions deliver between R-18 and R-21 thermal insulation – outperforming current glass and window product offerings by up to 4X. Enthermal™ high-performance glass can be customized for climatic regions (Low-E coating selection) and window sizes (glass thickness selection) to maximize return on investment. Enthermal™ is a uniquely low U-value glass that can be produced in a wide array of configurations to enable drop-in replacement of single and double pane insulating glass units.

Fully Tempered

LuxWall Enthermal™ delivers true innovation to the vacuum insulating glass segment, providing the first fully tempered vacuum solution to the market

Enthermal™. Designed to Solve.

Why You Need It

Enthermal™ vacuum insulating glass tackles the rising demands property owners face today and in the future. Better for your tenants. Better for your bottom line. Better for the world.

Up to 45% Energy Utility Savings

Enthermal™ solutions reduce energy usage up to 45% for single pane retrofits and up to 35% for double pane clear glass retrofits

2 - 7 Year Payback

Compared to current industry standards, provides a 3X reduction in payback period (based on single pane retrofit), as a direct result of energy cost savings, HVAC reduction and climatic region conditions

Limited Tenant Impact

Routine energy-efficient window installation completed from the interior of the building, using standard techniques in the glazing process

Increases Property Value and Leasing Rates

Upgrading to our energy-efficient vacuum insulating glass solution with available R values of 18+ is a smart way to increase the overall value and aesthetics of your property

Up to 50% Reduction in Installation Costs

Enthermal™ high-performance glass can be installed into existing commercial window frames, thereby eliminating the need for full façade or window replacement while still providing significant efficiency savings. We reduce glazing capital expenditures up to 50% over current glazing options.

Proactively Addresses Carbon Emission Tax Laws

40 countries and 20 cities have passed carbon emission laws. New York City Local Law 97 is the benchmark. Enthermal™ will help to meet the requirements
