lasittamaton

Lasittamaton is a Finnish adjective meaning unglazed or without glass. It is used to describe surfaces, panels, or enclosures that do not have glass panes. The term is most common in architectural and construction contexts, where components such as windows, facades, or partitions may be described as lasittamaton when glazing has not been applied or when glass is intentionally omitted. It contrasts with lasitettu (glazed) and lasitus (glazing).

The word is formed in Finnish from the noun lasi (glass) with derivational patterns that create negative adjectives, and it is primarily a technical or descriptive term. It is generally written in lowercase and does not denote a brand or proper noun. While widely understood in relevant professional contexts, its everyday use may be limited to discussions of building stages or design equipment.

In practice, speakers often describe a structure more simply as "ikkuna ilman lasia" (a window without glass) or refer to the glazing stage in construction rather than using lasittamaton as a stand-alone descriptor. The term does not carry specific cultural or historical significance beyond its linguistic and architectural usage. Overall, lasittamaton serves as a precise, context-dependent way to denote the absence of glazing in Finnish technical language.
