When it comes to home renovations, upgrading windows is one of the most effective ways to improve energy efficiency, comfort, and aesthetics. However, many homeowners hesitate because replacing entire window frames can be expensive, time-consuming, and disruptive. Fortunately, there’s a smarter alternative: vacuum insulating glass (VIG).
Vacuum insulating glass is a high-performance glazing solution that replaces only the glass panes while keeping the existing window frames intact. This innovative technology offers numerous advantages over traditional window replacement. Below are five key benefits of choosing vacuum insulating glass for your home renovation.
Replacing glass only instead of replacing whole windows
1. Easier and Faster Than Replacing Whole Windows
One of the biggest challenges of window replacement is the labor-intensive process of removing and installing entire window frames. This often involves:
- Demolishing parts of the wall
- Dealing with structural adjustments
- Extended installation time
With vacuum insulating glass, only the glass panes are replaced, making the process much simpler and faster. There’s no need to remove the frames, meaning:
- Minimal disruption to your daily life
- Faster installation (often completed in a single day)
- No need for extensive cleanup afterward
This makes VIG an ideal solution for homeowners who want an upgrade without the hassle of a full window replacement.
2. Much More Cost-Effective Than Full Window Replacement
Replacing entire windows can be expensive, especially if you have many windows or custom-sized frames. Costs include:
- New window frames
- Labor for removal and installation
- Potential repairs to walls and trim
Vacuum insulating glass, on the other hand, cuts costs significantly because:
- You reuse the existing frames
- Labor is reduced since only the glass is replaced
- No additional construction work is needed
This makes VIG a budget-friendly alternative that delivers similar (or even better) performance than new windows at a fraction of the price.

3. Dramatically Improves Thermal Performance, Even with Old Frames
Many older homes have beautiful but inefficient windows. Instead of replacing the entire frame, vacuum insulating glass enhances thermal performance by:
- Reducing heat transfer due to its vacuum layer (which is far more insulating than standard double glazing)
- Minimizing drafts when combined with proper sealing
- Maintaining indoor temperatures better, reducing reliance on heating and cooling systems
Even if your window frames are decades old, VIG can transform them into energy-efficient barriers without sacrificing their original charm.
Compared with normal single glazing -5.8W/M2.K average U value,vacuum insulating glass can reach an U value of just 0.45W/M2.K,which is even 30% better than the most high end triple insulating glass which thickness is normally 45-55mm.

4. Fits Any Window Frame Due to Its Thin Design
One of the standout features of vacuum insulating glass is its ultra-thin thickness. Unlike bulky triple-glazed units, VIG is:
- Only slightly thicker than single-pane glass, making it compatible with almost any frame
- Perfect for historic homes where preserving original windows is important
- Versatile for modern windows without requiring structural changes
Whether you have wooden sash windows, aluminum frames, or vinyl casements, VIG can be seamlessly installed without modifications.
Buildings built before the 2000s were equipped with mostly single glazing or double glazing,which don’t contain any energy saving coatings or functional coatings that decrease the windows energy consumption,now in 2025,you can just replace your original glass with vacuum insulating glass to changing your windows to be an superior energy efficient windows whose thermal performance surpass even the newest windows series.
5. Additional Benefits: Noise Reduction, No Condensation, and Lower Energy Bills
Beyond thermal efficiency, vacuum insulating glass provides several extra advantages:
A. Creates a Quieter Living Environment
The vacuum layer blocks sound transmission more effectively than standard glass, reducing outside noise from traffic, neighbors, or city life.
B. Eliminates Winter Condensation
Traditional windows often suffer from condensation in cold weather, leading to mold and moisture damage. VIG’s superior insulation keeps the inner glass warmer, preventing condensation buildup.
C. Saves on Electric Bills
By improving insulation, VIG reduces the workload on your HVAC system, leading to lower energy consumption and reduced utility costs year-round.
