What Is a Sash Window Double Glazing Retrofit?
Sash windows are a key architectural feature in many period properties and heritage buildings. However, their single-glazed panes allow for significant heat loss, drafts, and poor insulation, making them far less efficient than modern glazing options.
A sash window double glazing retrofit involves replacing or upgrading the glass in existing sash windows to improve thermal performance, while maintaining their traditional look. However, not all retrofits are created equal—choosing the right glazing is crucial for performance, appearance, and longevity.
That’s where LandVac vacuum glazing stands out, offering a modern, energy-efficient solution that blends seamlessly with historic window designs.
Why Choose LandVac Vacuum Glazing for Sash Window Retrofits?
LandVac is a leader in vacuum glazing technology, offering superior performance for sash window double glazing retrofits. Here’s why it’s the best choice:
1. Does Vacuum Glazing Maintain the Traditional Look of Sash Windows?
Yes! One of the biggest challenges of retrofitting sash windows is that traditional double glazing is often too thick, making it look out of place in period homes.
LandVac vacuum glazing is just 8.3mm thick, closely resembling single glazing while offering modern insulation. This makes it an ideal choice for listed buildings and conservation areas, where preserving the original appearance is a priority.
2. How Energy Efficient Is LandVac Vacuum Glazing?
LandVac outperforms traditional double glazing by using a vacuum-sealed space between the panes to create a powerful thermal barrier.
- U-value as low as 0.4 W/m²K (better than slim double glazing)
- Keeps homes warmer in winter and cooler in summer
- Reduces reliance on heating and cooling, lowering energy bills
3. Can Vacuum Glazing Reduce Noise?
If you live in a busy city or near a main road, noise pollution can be a major issue.
LandVac vacuum glazing offers excellent sound insulation, significantly reducing external noise. This makes it an ideal solution for urban homes and properties in high-traffic areas.
4. How Long Does Vacuum Glazing Last?
LandVac vacuum glazing is designed to be durable and long-lasting.
- Sealed vacuum layer prevents condensation and fogging
- Low risk of unit failure, unlike slim double glazing, which often fails within 10-15 years
- 15-year warranty, offering long-term peace of mind
5. Can Older Homes Be Made More Energy Efficient Without Replacing Windows?
Yes! Upgrading older properties to modern insulation standards can be challenging, as traditional sash windows often can’t accommodate thick double glazing.
LandVac’s slim profile means you can upgrade your glazing without replacing the entire window, making it the ideal sash window retrofit solution.
6. Is Vacuum Glazing a Sustainable Choice?
With sustainability becoming a priority for homeowners, LandVac vacuum glazing is an eco-friendly option:
- Reduces heat loss, cutting energy consumption and carbon emissions
- Uses sustainable materials, minimising environmental impact
- Long lifespan, reducing waste compared to traditional glazing options
How Does LandVac Vacuum Glazing Work?
LandVac’s advanced vacuum glazing system uses:
- Two layers of glass with a vacuum-sealed space between them
- A highly efficient thermal break, preventing heat transfer
- Tiny support pillars, keeping the panes apart while maintaining transparency
- Advanced coatings, further improving insulation
This unique design allows LandVac to match or exceed the performance of traditional double glazing—but with a thinner profile, making it perfect for sash window retrofits.
