From the winding streets of Tbilisi to the hilltop homes of Sighnaghi, Georgia’s historic architecture is a national treasure. But with most buildings dating back to an era before insulation standards, improving energy performance is a growing concern — especially as Georgia moves toward EU-aligned environmental targets. Read on to find out more about improving the energy performance of historic buildings with LandVac Vacuum Glass in Georgia.
For architects and specifiers, this raises a critical challenge: How can we preserve historic beauty while meeting modern energy efficiency requirements?
The answer lies in advanced glazing solutions — specifically, LandVac vacuum glass.
Why Focus on Glazing?
In heritage buildings, windows account for up to 40% of overall heat loss, especially when single glazing and leaky frames are involved. Data from a UK-based study of heritage sash windows shows that:
Single-glazed sash windows have a U-value of 5.30 W/m²K, losing 100% of possible heat through glazing.
Air leakage from these windows can reach 183 m³/hr at 50Pa, resulting in massive energy waste and discomfort.
Even with minor interventions like draughtproofing or secondary glazing, performance remains limited.
LandVac Vacuum Glass: Quantified Performance
Unlike slim double-glazing or secondary units, LandVac delivers dramatic gains both thermally and acoustically — without compromising aesthetics.
Let’s compare performance figures:
| Window Type | Glass U-value (W/m²K) | Whole Window U-value | Heat Loss Reduction | Air Leakage at 50Pa (m³/hr) |
|---|---|---|---|---|
| Single Glazing | 5.30 | 4.30 | 0% | 183.00 |
| Slim Double Glazing | 1.90 | 2.10 | ~64% | 26.00 |
| Secondary Glazing | 2.00 | 1.80 | ~62% | 8.00 |
| LandVac (New Window) | 0.40 | 1.12 | Up to 92% | 3.11 |
In terms of thermal conductivity, LandVac cuts glazing heat loss by up to 92% and reduces whole-window heat loss by 74%, outperforming every alternative tested.
Heritage Compliance Without Compromise
LandVac achieves these results with a profile thickness of just 8.3mm — meaning it can be retrofitted into original timber frames without altering frame dimensions or aesthetics. This is especially valuable in Georgian heritage zones like Tbilisi’s Sololaki district or Mtskheta’s protected structures.
Furthermore:
No need for secondary glazing (which changes the interior appearance)
No visible vacuum ports – preserving the authentic look
Reduced condensation – protecting woodwork and plaster finishes
Improved acoustic insulation – ideal for busy urban sites
Boosting Lifetime Energy Savings
The referenced study also measured energy output:
A single-glazed window loses up to 92.2 kJ per hour
A LandVac-equipped window loses only 24.0 kJ — a 74% reduction in real-world energy waste
Over a winter heating season, that translates to significant cost savings, lower emissions, and greater occupant comfort — all while keeping the historic façade untouched.
Suitable for Georgian Renovation Projects
Specify LandVac Vacuum Glass in Georgia, whether you are restoring:
A boutique guesthouse in Telavi,
A museum in Kutaisi, or
An apartment conversion in Old Tbilisi,
LandVac enables you to meet both energy performance goals and heritage regulations in one solution.
Its light weight and ultra-slim form factor reduce the need for structural adjustments, and it’s already in use across Europe in buildings of national importance.
Conclusion: Design for the Future, Preserve the Past
Georgia stands at a crossroads: its historic architecture must not only be preserved but also made resilient to a changing climate. LandVac vacuum glass is the bridge between yesterday’s craftsmanship and tomorrow’s energy standards.
If you’re specifying for a historic renovation, consider the data-backed performance of LandVac — a conservation-friendly technology that futureproofs your project without compromising on style.
