Aluminium Transom windows

Aluminium thermal break transom windows, opening inwards, with hinges at the bottom and a fastener at the top. Ideal for service areas, bathrooms, garages and in all those rooms where no outside view is required. They guarantee light and ventilation.

System 75

Profile with flat line and tape hardware. Modern design and excellent thermal insulation and soundproofing performance. These are windows that protect from the cold, keep out draughts, dust and humidity, giving a more comfortable domestic environment.

System 75AD

Profile with flat line, with European double-pane hardware and flush hinges fitted as standard. Extremely elegant lines, thanks to the fact that the sash is flush. This means that only the frame can be seen from the outside. Windows that protect from the cold and from bad weather, guaranteeing greater living comfort.

System 80

An innovative, high performance and sustainable profile. It has a square, modern line, tape hardware and thanks to the absence of a central plastic seal it is easier to clean and even more “green”.
