Duravent has established itself as a pivotal force in the venting industry since its founding in 1956.

Initially launched by Dover Corporation in Redwood City, California, Duravent began by manufacturing type B vents designed for natural gas or liquid propane appliances.

Over the years, the company expanded its product range and geographical footprint, showcasing its capacity for innovation and growth.

In 1982, Simpson Manufacturing acquired Duravent, significantly boosting its manufacturing capabilities with new facilities in Vacaville, California, and Vicksburg, Mississippi.

This expansion allowed Duravent to meet increasing market demands effectively.

By 1992, Duravent introduced DirectVent GS, a leading vent system for direct-vented gas fireplaces and stoves, highlighting its commitment to innovation and safety.

A significant transformation occurred in 2010 when M&G Group purchased Simpson Dura-Vent, renaming it M&G DuraVent. This acquisition integrated Duravent into a larger consortium, enhancing its resource and technology base.

Further strengthening its market position, Duravent acquired Security Chimneys International in 2012, adding reputable chimney solutions to its portfolio.

Duravent’s commitment to quality and innovation remains evident as it continuously develops new products and enhances its service offerings.

With 13 distinct brands and a robust presence across North America, Duravent not only leads in technological advancements but also prioritizes sustainable and safe manufacturing practices.
