AI Technical Summary
Technical Problem
Existing laminated glazing technologies face challenges in achieving high selectivity, excellent color neutrality, and consistent production while maintaining good thermal and optical performance.
Method used
A laminated glazing design featuring two transparent substrates separated by a puff pastry, with one substrate coated with a functional coating comprising metallic layers between dielectric coatings, and the second substrate coated with a low-emissive coating, both deposited using a magnetron cathodic spray process.
Benefits of technology
The solution achieves a light transmission between 25 and 44%, low light reflection, and high selectivity, while ensuring aesthetic neutrality and consistent production quality.
