Topp
Window and door automation for natural ventilation, smoke control, and building access.
Southern Africa (South Africa, Namibia, Botswana, Mozambique, Zimbabwe, Zambia)
Topp is an Italian manufacturer of window and door automation, made in Italy and protected by numerous international patents. For more than 20 years Topp has engineered its actuators and operators around one aim: the right balance of design, function, and reliability. The range covers natural ventilation, smoke and heat exhaust ventilation. Every Topp device is tested individually in the company's own laboratory, and Topp automation runs in airports, stadiums, hospitals, and offices worldwide. DNH is the authorised South African distributor: we consult on selection and sizing from our Johannesburg office and handle warranty locally under Topp's standard terms.
Why Topp?
Topp designs and manufactures its window and door automation in Italy. Its actuators are protected by numerous international patents, including the patented chain path that lets a slim housing deliver a long stroke.
Topp covers a building's openings from a single manufacturer. Chain, stem, and rack actuators drive windows, domes, and louvres. Swing and sliding operators automate pedestrian doors.
Topp RWA actuators are tested to EN 12101-2 for smoke and heat exhaust ventilation. Topp door operators are tested to EN 16005 for safety on motorised pedestrian doors.
Every Topp device is tested individually in the company's own test laboratory. Topp automation runs in airports, stadiums, hospitals, hotels, and offices internationally.
