9 Reasons Vacuum Glazing is Perfect for a Glass Façade

LandVac vacuum glazing is revolutionising the way architects and developers think about glass façades. Whether you’re designing for sustainability, aesthetics, or acoustic comfort, LandVac delivers high performance in a surprisingly slim package.

Here’s why it’s the ideal choice for contemporary façades and retrofit upgrades alike.

1. Exceptional thermal performance in a slim profile

LandVac delivers U-values as low as 0.34 W/m²K. It offers better insulation than most triple glazing, but in a unit just 8.3 mm thick.

This ultra-slim construction:

• Reduces visual bulk around mullions and frames
• Supports sleek, modern façades without compromising energy efficiency
• Helps meet ambitious net zero and Future Homes targets

2. More natural light, less visible frame

Because LandVac is so thin, it allows for:

• Larger glazed areas with minimal framing
• Better daylight penetration deep into the building
• A lighter, more refined aesthetic

It’s the glazing equivalent of having your cake and eating it.

3. Powerful acoustic insulation

LandVac provides an average noise reduction of 39 dB and can go as high as 41 dB reduction, making it perfect for buildings near:

• Railways or flight paths
• Busy roads or construction zones
• Urban centres where peace and quiet matter

In other words, it blocks out the city noise. Not the view.

4. Lightweight and easier to install

Compared to bulky triple-glazed units, LandVac is:

• Lighter per square metre
• Easier to handle and fit
• More forgiving for delicate structures or existing frames

It reduces structural load. It can also simplify the engineering behind large-scale façades.

5. Ideal for retrofitting and refurbishment

Because it mimics the look of single glazing but performs like triple, LandVac is an excellent solution for:

• Upgrading heritage or listed buildings
• Projects needing slim profiles or frameless systems
• Conservation-sensitive façades where visual change must be minimal

You get 21st-century performance. And a 19th-century appearance.

6. Durable, long-lasting, and mist-free

LandVac units come with a 25-year warranty and are built to last:

• No risk of argon leakage or internal misting
• Robust edge sealing for extreme temperature cycles
• Proven through accelerated age testing

Once it’s in place, it stays performing. Year after year.

7. Supports sustainability and lifecycle efficiency

LandVac glazing:

• Reduces heating and cooling demand
• Enables carbon savings across the building’s lifecycle
• Has a long service life, reducing waste and replacement needs

8. Performs consistently at any angle

Unlike gas-filled glazing units, LandVac doesn’t lose performance when installed at an angle. That means you can design sloping façades, rooflights, or architectural features without compromising thermal performance.

It opens up more creative freedom for architects, while still meeting the highest efficiency standards.

See it in action in this angled façade case study from Bavaria. It shows how LandVac performs in a sloped glass wall exposed to direct sunlight, while maintaining excellent energy efficiency, clarity, and indoor comfort.

9. Available in large sizes for bold designs

LandVac isn’t just for small windows. It’s available in sizes up to 2.4 metres by 4.2 metres.

That makes it ideal for:

• Expansive glass façades and curtain walling
• Floor-to-ceiling views and full-height glazing
• Contemporary architecture that demands scale without sacrificing performance
