Improve Thermal Performance of PVC Windows with LandVac Vacuum Glazing

PVC windows are a popular choice for homeowners due to their affordability, low maintenance, and energy efficiency. However, their thermal performance can decline over time as traditional double glazing loses its effectiveness. Fortunately, there is a solution to improve the thermal performance of PVC windows without replacing the frames—by upgrading to LandVac vacuum glazing.

The Issue with Aging Double Glazing

While double glazing initially provides good insulation, it does not maintain peak performance indefinitely. Over the first 10–15 years, the insulating gas between the panes begins to leak, leading to a significant drop in thermal efficiency. Even though the glass may appear intact, the reduction in performance results in higher energy bills and reduced indoor comfort.

A Smarter Upgrade: LandVac Vacuum Glazing

Rather than replacing entire window units, you can significantly boost the insulation of PVC windows by reglazing with LandVac Optimum S1.10 25.1mm glass. This cutting-edge vacuum glazing technology delivers outstanding thermal performance while keeping your existing PVC frames and glazing method unchanged.

By replacing older double glazing with LandVac Optimum S1.10 25.1mm glass, the overall window U-value improves from 2.64W/m²K to 1.07W/m²K. This results in better insulation, improved energy efficiency, and a more comfortable indoor environment—without compromising the sleek appearance of your PVC windows.

The Alternative: LandVac Enhance with VacuGask™

For homeowners seeking a balance of efficiency and durability, another excellent option is 8.3mm LandVac Enhance combined with VacuGask™. This setup provides the same thermal performance enhancement with additional benefits:

• Industry-Leading Warranties: VacuGask™ ensures a secure and airtight seal, extending the lifespan of the LandVac glazing unit.
• Consistent Long-Term Performance: Unlike conventional double glazing, which deteriorates over time, vacuum glazing retains its insulation properties for decades.
• Minimal Frame Adjustments: Using 8.3mm LandVac Enhance with VacuGask™ makes installation easier while delivering substantial thermal efficiency improvements.

Key Benefits of Upgrading PVC Windows with LandVac

• Superior Thermal Efficiency: U-value improvement from 2.64W/m²K to 1.07W/m²K, significantly reducing heat loss.
• Long-Lasting Insulation: Vacuum glazing maintains its thermal properties far longer than traditional double glazing.
• No Frame Modifications Required: A straightforward upgrade that preserves the appearance and functionality of your PVC windows.
• Reduced Condensation: Enhanced insulation helps prevent condensation, protecting window frames and interior spaces from moisture damage.
• Lower Energy Costs: Increased thermal efficiency leads to reduced heating and cooling expenses, making your home more energy-efficient and environmentally friendly.

A Simple Yet Powerful Solution

Whether your PVC windows currently have aging double glazing or you want to maximize energy efficiency, upgrading to LandVac vacuum glazing or LandVac Enhance with VacuGask™ is an ideal solution. With no need to alter the existing frames, you can enjoy superior insulation, lower energy bills, and enhanced home comfort—without sacrificing the modern look of your PVC windows.
