Diquigiovanni was founded in 1967 in Castelgomberto (Vicenza, Veneto), as a producer of aluminum windows and doors. At the close of the 1980s, Diquigiovanni began specializing in the production of windows and doorframes in PVC, a product characterized by excellent performance in terms of thermal and acoustic isolation, durability, recyclability, limited maintenance costs and competitive pricing over other materials traditionally used. The company distributes its products via two main channels: retailers covering the Italian territory targeting building renovations, and building site channel targeting, with the support of specialized agents, and new constructions.

In May 2016, Diquigiovanni was sold to a group of private investors.
