How Enthermal™ Plus compares
Compare Enthermal Plus™ to double-pane, thin triple-pane, triple-pane, and Enthermal™ windows – on the metrics that really matter.
Where numbers add up to comfort
Enthermal Plus™ doesn’t just promise efficiency — it delivers. Independent metrics show better insulation, steadier temperatures, and reduced energy loss.
50% energy savings
Cuts energy use up to 50% versus single pane; 35% vs. double-pane.
50% noise reduction
Up to 50% noise reduction compared to single-pane glass; 20% vs. double-pane.
60% CAPEX savings
Up to 60% CAPEX savings LuxWall’s Glass-Only Retrofit, when existing frames are retained.
Exceptional thermal performance
Innovative construction
This 1-inch insulating glass unit (IGU) combines LuxWall’s Enthermal™ slim profile vacuum technology with a traditional insulating glass unit.
Exceptional thermal performance
It delivers an impressive 0.045 U-factor—more than 5X the performance of standard double-pane units and 3X the performance of triple-pane units.
Seamless integration
Enthermal Plus™ fits seamlessly into your existing 25mm (1”) IGU framing system, no engineering re-design or factory retooling is required.
Everyday comfort and efficiency
Give your customers next-level energy efficiency, noise reduction, condensation resistance, and year-round comfort—without changing your product design.
