Upgrading windows in Romania’s historic buildings—whether it’s a 19th-century townhouse in Bucharest or a Saxon cottage in Transylvania—demands more than energy efficiency. It requires respect for architectural heritage and smart use of technology.

For years, slim double glazing was the go-to solution for period properties. But as technology has evolved, so have the options. Vacuum glazing has now emerged as a vastly superior alternative, offering exceptional performance while preserving original aesthetics.

Why Replace Slim Double Glazing?

Slim double glazing may be “thinner” than traditional units, but it still poses problems:

• Distorted Aesthetics: The added thickness can alter the proportions of delicate wooden window frames.

• Visual Disturbance: Double reflections and visible seals can be jarring in heritage settings.

• Moderate Efficiency: With U-values typically between 1.3–2.2 W/m²K, it's simply not good enough for Romania’s increasingly demanding winters.

• Limited Lifespan: Seal failures often appear within 7–10 years, leading to condensation and loss of clarity.

Vacuum Glazing: A Modern Solution for Timeless Buildings

Vacuum glazing, like the high-performance LandVac panels, offers a breakthrough for Romanian heritage homes:

• Ultra-Thin Profile: As slim as 8.3mm—almost indistinguishable from original single glazing.

• Superior Insulation: Achieves U-values down to 0.4 W/m²K, cutting heating costs dramatically.

• Acoustic Control: Reduces outside noise by up to 39dB, ideal for urban centres like Cluj, Timișoara, or Iași.

• Longer Lasting: Backed by 15-year warranties and 25-year life expectancy.

• Compatible with Original Frames: Lightweight and stress-free on fragile timber.

Romanian Conservation in Mind

In Romania, historic buildings are protected under national heritage laws, and window upgrades often require approval from the Direcția Județeană pentru Cultură. Vacuum glazing is increasingly favoured for its near-invisible impact on façades, particularly in protected zones like Sibiu’s historic centre or Brașov’s Old Town.

Final Verdict: Upgrade, Don’t Compromise

Slim double glazing was once a useful compromise. Today, vacuum glazing allows Romanian homeowners to achieve both sustainability and heritage preservation—without sacrifice.
