About Topp

Topp are an Italian manufacturer of window openers and window controls, and they manufacture what we believe to be the most popular window openers on the market, the ACK42 & the ACK44.

Topp has a range of chain actuators, linear actuators, and window controls for natural ventilation, some RWA products for smoke ventilation systems.  We find them particularly popular for conservatory roof vents, roof light and skylight windows.  They are also widely specified for high-level windows in schools, colleges, and universities for example.
