Product Description

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

Vacuum Insulated Glass
🔥
Thermal Insulation: U-Value as low as 0.4W/(m²·K). An 8.3 mm thick LandVac has better thermal insulation effect than a 1.5m thick brick wall.
🔇
Noise Reduction: Weighted sound reduction index exceeding 36dB, making rooms in downtown areas as quiet as a library.
❄️
Free of Condensation: Remains clear even when temperatures fall below -70 °C. The ultra-low dew point allows exceptional transparency for buildings and freezers.
🛡️
Tempered Safety: Meets tempered glass standards with wind resistance up to ±7200Pa and surface stress exceeding 90MPa.

Frequently Asked Questions

What is the U-value of LandVac vacuum insulated glass?
The thermal insulation performance is exceptional, with a U-value as low as 0.48 W/(m²·K), which is 2 to 4 times better than standard insulated glass.
Is the glass safe and tempered?
Yes, it is fully tempered vacuum insulated glass. Using low-temperature sealing technology, it retains the high strength and safety features of tempered glass, meeting all safety glass standards.
How effective is it at soundproofing?
LandVac effectively blocks sound transmission, particularly low and medium frequency traffic noise. It provides a weighted sound insulation measurement of up to 39 dB.
Does condensation form on the glass in cold weather?
No. Due to its high vacuum interspace and thermal performance, the interior surface remains free of condensation even when outdoor temperatures drop as low as -40 °C.
What is the expected lifespan of these panels?
The life expectancy exceeds 25 years. The flexible edge sealing and built-in getter materials ensure the vacuum remains stable even in harsh environments.
How thin and heavy is the glass?
It is significantly lighter and thinner than traditional triple-pane glass. A standard panel is approximately 8.3mm thick and weighs 20-28 Kg per square meter.
