LandVac Vacuum Insulating Glazing FAQs: Efficiency, Historic Window Fits & Warranty Explained
Q: How does LandVac VIG's specific energy efficiency (e.g., its U-value) translate into realistic annual savings on heating and cooling bills compared to older windows?
A: LandVac vacuum insulating glazing features an exceptionally low U-value (center of glass often around 0.4 W/(m²·K)), significantly outperforming single (~5.8) and standard double glazing (~1.1+). This drastically reduces heat transfer, potentially leading to substantial reductions in both heating and cooling costs year-round. Actual savings depend on climate, home insulation, and energy rates, but the improved thermal efficiency is significant.
Q: Can LandVac VIG's specific slim profile (often 8.3mm) make it suitable for upgrading windows in older or historic buildings while retaining original frames?
A: Absolutely. LandVac vacuum glazing's typical 8.3mm thickness is a key benefit for heritage projects. It's comparable to old single panes and much thinner than traditional double glazing, often allowing it to be fitted into existing, slender historic window frames. This upgrades thermal performance dramatically while preserving the building's original character and aesthetics.
Q: What are the specific lifespan expectations and warranty details provided for LandVac VIG, particularly concerning the durability and integrity of the vacuum seal over time?
A: LandVac VIG is engineered for durability, with manufacturers often citing an expected lifespan of 25+ years. LandVac typically offers a warranty that specifically covers potential failure of the vacuum seal, ensuring sustained thermal insulation.
