As energy standards continue to rise across Europe, professionals in Lithuania are seeking smart, sustainable solutions—especially for older buildings with sash windows. Whether you're an architect renovating a heritage property or a window installer upgrading period homes, LandVac vacuum glazing offers an advanced retrofit solution that delivers energy efficient windows in Lithuania without compromising historic aesthetics.
Sash windows, commonly found in older Lithuanian buildings and architectural landmarks, are beautiful but notoriously inefficient. Single glazing allows heat to escape, increasing energy costs and reducing comfort—especially during harsh Baltic winters.
A sash window retrofit upgrades the glass while preserving the original window frame and style. With the right choice of glazing, you can boost thermal performance, reduce environmental impact, and meet modern energy requirements—all without altering the building’s character.
LandVac vacuum glazing stands out as the preferred retrofit solution for sash windows. Here’s why it’s perfectly suited for projects in Lithuania:
At just 8.3mm thick, LandVac closely resembles single glazing—essential for maintaining the appearance of period windows. It’s ideal for conservation areas and listed buildings across Vilnius, Kaunas, Klaipėda, and beyond.
With a U-value as low as 0.4 W/m²K, LandVac delivers insulation performance that rivals or exceeds traditional double glazing. This means:
Better comfort in both winter and summer
Reduced reliance on heating systems
Lower energy bills for homeowners and commercial property owners
Urban noise is a growing concern in Lithuania’s bustling cities. LandVac’s vacuum layer acts as a powerful sound barrier, helping reduce noise from traffic, construction, and city life.
Unlike slim double glazing, which often fails within 10–15 years, LandVac is built to last:
Vacuum seal prevents internal condensation
15-year warranty ensures peace of mind
Reduced maintenance costs over time
With growing attention on green building practices in Lithuania, LandVac supports sustainability goals:
Lower energy usage = reduced carbon footprint
Durable design = less material waste
Made with environmentally responsible components
Many Lithuanian towns and cities are rich with history—and that includes their architecture. Whether you’re working on a manor house in Trakai or a city townhouse in Vilnius Old Town, LandVac allows you to meet modern energy standards while preserving the original charm.
Because of its slim design and superior performance, LandVac makes retrofitting easy—no need to replace entire window frames. It’s a cost-effective, low-impact upgrade that adds long-term value.
For window installers and architects working on residential or commercial projects, LandVac vacuum glazing is the next-generation solution for sash window retrofits. It’s elegant, energy-saving, and designed with both performance and preservation in mind.
