Product Description
8mm Customized Soundproof Tempered Clear Vacuum Insulated Glass
🛡️
Thermal Insulation: U-Value as low as 0.4W/(m²·K). A 8.3 mm thick LandVac has better thermal insulation than a 1.5m thick brick wall.
🔇
Noise Reduction: Weighted sound reduction index exceeds 36dB, creating library-quiet interiors in downtown areas.
❄️
Free of Condensation: Maintains transparency even below -70 °C, ideal for buildings and freezers.
💎
Tempered Safety: Meets tempered glass standards with wind resistance up to ±7200Pa.

Production & Qualification
Frequently Asked Questions (FAQ)
What is the thermal insulation performance of LandVac?
LandVac features a high vacuum interspace that reduces the U-value to as low as 0.48 W/(m²·K), which is 2 to 4 times better than standard insulated glass.
How does it handle noise reduction?
The vacuum layer effectively blocks sound transmission, reducing outdoor noise level of 75 dB by approximately 39 dB, especially effective against traffic noise.
Is LandVac safe for use in high-rise buildings?
Yes, it is fully tempered with surface stress exceeding 90MPa, meeting international safety glass standards and offering wind resistance up to ±7200Pa.
Will condensation form between the glass layers?
No, the high vacuum interspace eliminates condensation even when outdoor temperatures fall to -40 °C (or lower depending on configuration).
What is the life expectancy of the vacuum glass?
The product is designed for a service life exceeding 25 years, utilizing flexible edge sealing and efficient getter materials to maintain performance.
What are the available dimensions for customization?
The maximum size is 1500x2500mm and the minimum size is 300x300mm, with thicknesses typically ranging from 8mm to 11mm.
