PVC windows are a favorite among Turkish homeowners for their sleek look, low maintenance, and cost efficiency. But over time, the thermal insulation of traditional double glazing declines—especially in regions with sharp seasonal temperature swings like Istanbul, Ankara, or Erzurum.
Instead of replacing entire windows, there's a smarter way to insulate glass and boost performance: LandVac vacuum-insulate glass.
Double-glazed windows lose efficiency as the gas between panes leaks out—usually within 10–15 years. This leads to higher heating bills in winter and uncomfortable interiors in summer. Even if the glass appears undamaged, its performance silently deteriorates.
LandVac Optimum S1.10 (25.1mm) is an advanced vacuum-insulate glass that fits right into your existing PVC frames. There's no need to replace window structures—only the glass.
This simple upgrade can lower your U-value from 2.64 W/m²K to just 1.07 W/m²K. That means less energy loss, better climate control, and lower costs—all while keeping your PVC windows looking sharp.
For tighter window setups or where minimal frame adjustment is needed, the 8.3mm LandVac Enhance, combined with VacuGask™, offers high-performance insulation and a reliable airtight seal.
This combo is especially useful in historic buildings, where preserving original frames is often a legal or aesthetic necessity. The result? Comfort and energy savings without altering the appearance.
