SkySheer + Vacuum Insulating Glass (VIG): Achieving R20+ and STC 40+ for Next-Generation Curtain Walls

Reducing energy consumption and lowering carbon emissions are top priorities in modern architecture and construction. The SkySheer's Frameless Curtain Wall System, when paired with Vacuum Insulating Glass (VIG), delivers a high-performance solution that meets these demands with exceptional thermal insulation, acoustic control, and structural strength.

Unmatched Thermal and Acoustic Performance

• R-Value of R20+: When SkySheer is combined with advanced VIG technology, the system can achieve R-values up to R20, far surpassing conventional insulating glass units (IGUs) and delivering wall-like thermal insulation. This level of performance translates into significant reductions in heat transfer, keeping interiors comfortable year-round and dramatically cutting HVAC energy use.

• STC Rating of 40+: The same configuration offers a Sound Transmission Class (STC) rating of 40+, providing robust sound attenuation for quieter, more private interiors-ideal for urban environments or noise-sensitive applications.

How VIG Technology Works

Vacuum Insulating Glass uses a thin vacuum layer between glass panes, virtually eliminating heat transfer by conduction and convection. This innovation provides thermal insulation that is 3–5 times better than conventional IGUs and up to 20 times better than monolithic glass, with consistent performance regardless of installation orientation.

Structural Integrity and Wind Load Resistance

SkySheer’s frameless curtain wall system eliminates the need for bulky aluminum mullions yet maintains or exceeds the wind load resistance of traditional systems. This is achieved through advanced double- and triple-pane IGU configurations:

• Double-pane SkySheer IGUs are 58% stronger than standard double-pane units.

• Triple-pane SkySheer IGUs are more than twice as strong as conventional triple-pane alternatives.

The insulating air or vacuum layer acts as a shock absorber, enhancing overall glass strength and durability while supporting larger spans and sleeker aesthetics.

Meeting Rigorous Energy Codes and Design Goals

This innovative combination is ideal for projects targeting stringent energy codes, LEED certification, or net-zero goals. SkySheer + VIG not only maximizes energy efficiency but also enables striking, uninterrupted glass facades that elevate architectural design.

Key Benefits at a Glance

• R20+ thermal insulation for major energy savings and carbon reduction

• STC 40+ for superior noise control

• Frameless aesthetic with no visible mullions

• Enhanced wind load resistance and structural strength

• Consistent performance in all orientations and climates

• Supports compliance with advanced building codes and sustainability targets

Conclusion

The SkySheer Frameless Curtain Wall System paired with Vacuum Insulating Glass represents a leap forward in building envelope technology. It empowers architects and developers to create visually stunning, high-performance buildings that are energy-efficient, resilient, and future-ready.
