Modern homes and buildings across Romania often use PVC windows for their affordability and low maintenance. However, over time, their thermal performance can decline—especially as older double glazing loses its insulating properties. The good news? You can upgrade to LandVac vacuum glazing to boost efficiency without replacing your window frames.
Double glazing doesn’t last forever. After 10 to 15 years, the insulating gas between the panes begins to escape, reducing performance. You may start noticing:
Cold drafts near windows
Higher heating bills
Condensation forming on the glass
Reduced indoor comfort
If your PVC frames are still in good condition, full window replacement isn’t necessary.
LandVac Optimum S1.10 (25.1mm) vacuum glazing is a high-performance solution that fits directly into your existing PVC frames. It dramatically improves insulation and energy efficiency without changing the look or structure of your windows.
Thermal upgrade: Reduce U-value from 2.64W/m²K to 1.07W/m²K
No frame replacement: Keep your current PVC windows
Fewer drafts and more indoor comfort
Lower energy bills and better temperature control year-round
If your PVC windows have slimmer frames, LandVac Enhance (8.3mm) combined with VacuGask™ provides excellent insulation with a sleek installation.
No need to modify frames
Long-lasting performance—no decline like double glazing
Improved airtightness and reduced condensation
Ideal for residential or commercial retrofits
Whether you live in an apartment in Bucharest or manage a commercial building in Cluj-Napoca, LandVac helps you improve thermal performance efficiently and affordably. With rising energy costs, upgrading your windows is one of the smartest investments you can make.
