🛡️ Product Description

Thermal Insulation Energy Saving 0.4 U-Value Thin Low-E Tempered Vacuum Insulated Glass Panel

Vacuum Insulated Glass

✨ Key Features:

  • Thermal Insulation: U-Value as low as 0.4W/(㎡·K). An 8.3 mm thick panel outperforms a 1.5m thick brick wall.
  • Noise Reduction: Sound reduction index exceeding 36dB, creating library-quiet environments.
  • Free of Condensation: No condensation even at temperatures below -70 °C.
  • Tempered Safety: Meets tempered glass standards with wind resistance up to ±7200Pa.

❓ Frequently Asked Questions (FAQ)
1. What is the thermal insulation performance (U-Value) of this glass? The LandVac vacuum insulated glass achieves a U-Value as low as 0.48 W/(m²·K) for single units and 0.42 W/(m²·K) for triple-glazed versions, providing superior insulation compared to standard insulated glass.
2. Is vacuum insulated glass safe for building use? Yes. It is fully tempered. By using exclusive low-temperature sealing technology, the glass retains its safety characteristics with surface stress exceeding 90MPa, meeting international safety glass standards.
3. How much noise can this glass block? It effectively blocks sound transmission with a sound reduction index exceeding 36dB. It is particularly effective against medium and low-frequency noises such as traffic and construction.
4. Does the vacuum layer cause condensation in winter? No. The high vacuum interspace eliminates dew condensation. The interior surface remains free of condensation even when outdoor temperatures fall as low as -40°C or even -70°C.
5. What is the expected service life of the product? The life expectancy of our vacuum insulated glass exceeds 25 years, thanks to flexible edge sealing technology and built-in high-efficiency getters that prevent material aging and seal failure.
6. What is the maximum size available for these panels? The maximum dimensions for LandVac panels are 1500 x 2500 mm, with a minimum size of 300 x 300 mm.
