Products Window pane, aerogel (Europe)
Silica aerogels can be used as transparent insulation spacer in evacuated windows for achieving low thermal heat loss while maintaining a high solar trasmittance.

This window pane is made from a 20mm thick aerogel slab sandwiched between two standard glass plates.

The main drawbacks are its optical clarity and its cost. The aerogel pane is slightly hazy, although theoretically complete transparency can be achieved.
