Transparent Insulation™
Transforming the building envelope into
See-Through Walls™ that protect comfort, performance, and value.
LuxWall is bettering the built environment one building at a time, forever redefining how the spaces we experience are designed, retrofitted, constructed, and brought to life. We believe superior energy efficiency should be accessible to ALL.
Energy efficiency for all.
LuxWall delivers transparent building envelopes that radically improve energy performance and occupant experience for every budget and every community.
A step-change in building innovation
LuxWall Transparent Insulation™ represents the first true breakthrough in centuries—insulating like a wall and cutting a building’s energy use by up to 45% to 50%.
Enthermal® TechnologyR-18 performance
Delivers wall-level insulation in a profile thinner than double-pane glass.
20-year warranty
Fully tempered vacuum technology with proven durability and reliability built to endure for decades.
Quieter interiors
20–30% improvement in sound attenuation at target street noise frequencies compared with standard windows.
Trusted at scale
Adopted by landmark buildings, trusted by leading Fortune 500 organizations, and validated by global property investors.
Cost-saving efficiency, faster ROI
LuxWall Glass-Only Retrofits fit existing frames, avoid capital intensive full window replacements, and deliver an accelerated payback period of 3 to 10 years.
Enthermal® TechnologyLower HVAC burden and costs
Reduces reliance on mechanical heating and cooling systems, translating into long-term maintenance and capital savings.
Improved interior condensation resistance
Advanced Transparent Insulation prevents cold interior surfaces, reducing damaging condensation effects inside the building.
Wall-level thermal performance
Vacuum technology and high performance Low-E coatings work together to eliminate convective heat transfer and dramatically reduce conductive and radiative heat transfer.
Lower lifetime energy costs
Stable interior temperatures reduce unnecessary energy use, driving durable cost savings and NOI lift over the building’s lifespan.
Quiet the noise. Enhance the comfort.
LuxWall Transparent Insulation™ doesn’t just keep heat in — it keeps noise out. With up to 30% better sound attenuation than double-pane glass, it transforms loud urban environments into quiet, comfortable spaces.
Enthermal® TechnologyOITC rating up to 32
Demonstrated Outdoor-Indoor Transmission Class improvement over existing glazing products.
Vacuum barrier
Enthermal’s ultra-high vacuum cavity removes the air path that enables sound waves, blocking the primary channel for outside street noise.
Disrupted vibrations
Micro-pillar spacing minimizes vibration between panes, scattering sound energy instead of transmitting through the window.
Thin yet powerful
Delivers superior performance without the use of thicker glass panes or laminated glass.
Design freedom that’s future-proof
LuxWall enables architects, developers, and property owners to meet building performance targets without sacrificing aesthetics, window to wall ratio or function.
Seamless integration
Thin, lightweight Enthermal® profiles fit into existing frames, enabling glass-only retrofits that avoid costly façade replacement.
Easy compliance
LuxWall helps your building meet or exceed national and local building energy performance requirements.
Proven ROI
Projects achieve investment payback in 3 to 10 years with double digit ROI, 3X to 5X better than full window replacements.
One breakthrough. Endless
customization.
LuxWall Transparent Insulation™ sets a new standard for energy efficiency. Choose the solution that fits your needs.
Enthermal®
The original breakthrough in Transparent Insulation™. Enthermal® delivers R-18 insulation performance in a profile thinner than double-pane glass, transforming windows into energy-efficient walls.
Enthermal Plus®
Enhanced efficiency. Maximum impact. With the same profile as double-pane glass, Enthermal Plus® delivers higher thermal performance, better condensation control, and quieter interiors.
