Vacuum Insulating Glass for Architectural Glazing
R-12+ center-of-glass thermal performance in profiles under 10mm. Curtain walls, historic retrofits, and passive house facades — without the bulk.
Architecture & Facades
Wall-Like Performance. Glass-Thin Profile.
Historically, achieving wall-like R-values meant adding weight, thickness, and bulk to window assemblies. THERMGLASS Warm-Edge VIG changes the rules of facade design — delivering Passive House-level performance while fitting historic retrofits, narrow sash frames, and modern lightweight curtain walls.
With a COG U-value of 0.46 W/m²K (0.081 Btu/h·ft²·°F) and profiles from 6.3mm to 20.3mm, THERMGLASS meets the most demanding energy codes — including Local Law 97 — without structural redesign.
Applications
Where THERMGLASS Performs
Curtain Wall & Structural Glazing
Certified for 2-sided and 4-sided structural silicone glazing (SSG) applications. Flexible warm-edge seal absorbs shear movement from wind load and differential thermal expansion — preserving SSG integrity across the full facade.
Historic Retrofits
Fits ultra-thin historic sashes — enabling net-zero thermal upgrades without altering original facades. Slim Monolithic VIG delivers R-12+ center-of-glass performance at a fraction of the thickness of conventional double-pane units.
Passive House & Net-Zero
Hybrid VIG configurations push center-of-glass thermal performance to R-25+, rivaling solid insulated walls. Fully compatible with ASHRAE 55, Passive House, and Local Law 97 compliance pathways.
Acoustic Urban Facades
STC 35–45 attenuation for high-density urban developments. Acoustic & High-Solar-Control VIG hybrids combine extreme sound reduction with low SHGC coatings to cut cooling loads.
Key Benefits
0.46 W/m²K COG U-Value
Center-of-glass performance approaching solid wall insulation — in a glass unit.
Up to 50% Weight Reduction
Dramatically lighter than standard triple-pane IGUs — reducing structural load requirements and shipping freight.
Zero Border Condensation
True warm-edge seal keeps perimeter temperatures uniform with center-of-glass — eliminating condensation and mold risk at frame edges.
Local Law 97 Compliant
Meets NYC Local Law 97 and equivalent energy codes across North America without facade redesign or structural upgrades.
