TOPP offers a wide range of simple, functional systems for the automation of doors and windows, designed to simplify our daily movements. Our natural vocation is a constant search for the perfect balance between design, function, technology and creativity.

For more than 20 years we have been offering our engineering know-how as an outside workshop, and our attention has always been focused on product innovation. Every device is tested individually to maintain our commitment to quality materials of the highest quality.


Benefits of window automation include:

► To reach hardly accessible window

► To automatically ventilate rooms

► To control safely the windows in case of rain

► To easily operate multiple windows simultaneously

► It allows great opportunities to achieve innovative solutions

► It enhances energy saving according to green thinking

► It gives great solutions to the needs of disabled people

► It has a worthy cost/benefit ratio
