DRAUGHT EXCLUDERS SINCE 1976
Our company was founded in 1976, introducing automatic draft excluders to Italy. More than 40 years after that first historical patent and thanks to the experience of three generations, Comaglio continues family business but its products are now of international fame. From the initial garage workshop where Aldo Comaglio created the first Italian prototype draft excluder, up to our modern premises of today, close to Lake Garda, craftsmanship and passion for the job continue to fire our activities.
LEADER COMPANY
HOW THE COMAGLIO DRAUGHT EXCLUDER WORKS
The first patent foresaw only two applications serving also as a drip, then evolution became the basis for Comaglio’s creative engineering process. And so it was that in the early 1980s Comaglio, with a small staff, opened a factory in Gavardo (BS).
After the opening of an Italian market showing interest for this innovative product, the Comaglio draught excluder faced the international scenario at the start of the 90s. Business has grown in terms of staff, investments, technology and solutions, customer care and satisfaction being still our main objective.
For this reason, we have answered the international market by extending our premises to cover the current area of 3,500 square metres in Muscoline (BS). Our quest is to identify solutions with the greatest care for details, using innovative and flexible production lines for our offer to a market in continuous evolution.
Today in more than 40 countries throughout the world, Comaglio is synonym of quality, precision and service.
