What's in a Prague street name

Perlitová was built in 1977.

‘Perlit’ is perlite – an amorphous volcanic glass with a high water content, and which, unusually, expands significantly upon heating.

It’s used a lot in construction and manufacturing, for example in ceiling tiles, insulation, concrete and lightweight plasters.

In the case of this street, a construction cooperative called Perlit-dom took part in the construction of its dwellings.
