Latvia is home to countless architectural treasures—from ornate Art Nouveau façades in Rīga to centuries-old wooden homes in small towns. Preserving these historic buildings while improving comfort and sustainability has become an increasing priority. A common challenge lies in replacing original windows without compromising heritage value.
That’s where LandVac vacuum glazing provides a groundbreaking solution: preserving historical aesthetics while significantly improving insulation and energy efficiency.
Historic homes and public buildings often feature beautiful but inefficient single-glazed wooden windows. While these elements are vital to a building’s character, they can’t meet today’s insulation standards—especially during harsh Latvian winters. Upgrading your windows can:
Improve interior warmth and comfort
Lower energy consumption and heating bills
Minimise condensation and damp issues
Preserve property value and extend lifespan
Reduce carbon emissions in line with Latvia’s green building goals
Upgrading windows in historic Latvian buildings isn't just a technical decision—it's a cultural one. You’ll need to work within strict planning guidelines to ensure visual integrity is preserved:
Architectural authenticity: Replacements must match the original design and proportions.
Planning approval: In protected zones or for classified buildings, visible changes are rarely allowed.
Structural limitations: Frames and surrounding materials may not support bulky double glazing.
Limited space: Traditional sash or casement frames can't accommodate modern thick units.
Unlike conventional double or triple glazing, LandVac vacuum glazing is just 8.3 mm thick but provides better insulation than triple glazing:
| Glazing Type | Thickness | U-value (W/m²K) |
|---|---|---|
| Single Glazing | ~4 mm | 5.0 |
| Slim Double Glazing | 11–16 mm | 1.2–1.5 |
| LandVac Vacuum Glass | 8.3 mm | 0.4 |
This ultra-slim design allows LandVac units to be inserted into original frames, preserving historic sightlines and avoiding major alterations.
LandVac vacuum glazing is ideal for replacing windows in Latvian historic buildings because it:
Fits inside existing timber or metal frames
Avoids double reflections (common in double glazing)
Preserves slender frame proportions
Enhances interior comfort without changing the exterior
Supports conservation compliance in heritage zones
Energy loss through windows is one of the biggest issues in Latvia’s older buildings. LandVac offers:
Up to 90% less heat loss than single glazing
Reduced heating demand in winter
Stable interior temperatures year-round
Condensation control, especially near coastal or humid regions like Liepāja or Daugavpils
LandVac vacuum glazing has been successfully used in conservation areas across Europe. Its non-invasive installation, authentic appearance, and ultra-thin profile make it far more likely to gain planning approval for protected buildings in Latvia.
Whether it’s a Jugendstil townhouse in central Rīga or a 19th-century manor in the countryside, LandVac makes it possible to future-proof historic buildings without altering their charm. Experience comfort, sustainability, and heritage preservation—together in one simple upgrade.
