About us History

“Nihil est enim simul et inventum et perfectum” (“Nothing is invented and perfected at the same time”). These words attributed to Cicero over 2000 years ago are of particular significance for the invention and further development of PVC-U windows at our company.

Not only has TROCAL developed the PVC-U window for series production, but also its developments have been setting standards on the market.
