1. Unsurpassed thermal insulation: 0.018 W/m.K. This allows more natural daylight
through a roof and/or a facade while minimizing heat loss.
2. Good light transmission: up to 80% per cm. Natural daylight creates a more efficient
and beneficial interior environment, with positive psychological and physiological effects.
3. Improved acoustic insulation: 100 m/sec vs. 340 m/sec in air. 50% reduction at 100Hz.
