The 25-year service life of our vacuum glass is determined based on two primary factors: material composition and rigorous accelerated ageing protocols.

1. Material Composition and Structural Integrity

The longevity of our product is fundamentally rooted in its inorganic construction, which eliminates the risk of traditional material fatigue.

All-Inorganic Build: Our vacuum glass consists exclusively of glass and metal components. By excluding organic materials, such as adhesives or resins, we eliminate the risk of chemical ageing and degradation over time. The internal spacers and edge seals are entirely metallic, ensuring a stable structure.

Titanium Alloy Sealing: We utilise a specialised titanium alloy for edge sealing. This material is specifically chosen to overcome the brittleness associated with conventional sealing materials, allowing the unit to maintain its integrity despite the stresses of thermal expansion and deformation.

High-Efficiency Getters: To ensure long-term performance, we integrate high-efficiency getters within the vacuum cavity. These components maintain the required high vacuum levels over the long term by chemically absorbing trace gases.

2. Accelerated Ageing Simulation

We verify the durability of our glass through advanced simulation testing that mimics long-term environmental exposure.

Full-Spectrum Radiation Testing: Using sophisticated full-spectrum equipment, the glass is subjected to continuous irradiation.

Calculation Standards: Every 900 hours of testing in this controlled environment is equivalent to one year of natural outdoor ageing.

Testing Milestones: Our glass has currently exceeded 22,500 hours of continuous testing. Based on the established conversion rate, this confirms a functional lifespan of 25 years or more.
