Company History

Today, DuraVent has continued its success since its origins over 50 years ago. With 24 available product lines, DuraVent has a large portion of the Chimney Market and continues to innovate new products.

DuraVent is the premier company of the venting industry. With a broad range of engineered venting products, DuraVent has earned its reputation as the industry leader by offering innovative, safe, and professional products for the HVAC and Hearth markets.


Dura-Vent opened for business in January of 1956 in Redwood City, CA by Dover Corporation, making type B vents for natural gas or liquid propane appliances.


DuraChimney came on board as the company's first wood chimney system. For a short period of time during these early years, the company also made rain gutters and downspouts.


Simpson Manufacturing purchased Dura-Vent and established a manufacturing plant in Vacaville, CA. Another manufacturing company was set up in Vicksburg, MS to supply the growing demand for venting products.


DirectVent GS was developed for venting direct-vented gas fireplaces and stoves.

DirectVent is the industry's top vent for these popular appliances. Unitized construction and the patented twist-lock connection provides quick, safe and easy construction.

PelletVent was created by Simpson Dura-Vent as the first venting pipe for the newly developed pellet stoves. Pellets were a totally new fuel innovation and Simpson Dura-Vent developed the protocols for the venting standards. Every major pellet stove manufacturer in the industry now recommends PelletVent.


DuraPlus HTC was developed to offer a high-class chimney for the unique requirements of Canadian standards.


Simpson Dura-Vent acquired both the Ventinox product line from America Boa and Protech Systems, a highly respected manufacturer of Hearth, HVAC, and PHC products.


The M&G Group acquired Simpson Dura-Vent on September 1, 2010, becoming one of 13 companies in the privately held M&G consortium. Simpson Dura-Vent becomes known as M&G DuraVent, Member of the M&G Group.

M&G Group, headquartered in the Netherlands, produces a wide range of flue and vent products in aluminum, stainless steel and plastic. It is the largest supplier of engineered venting systems for the high-efficiency heating market in Europe.


M&G DuraVent acquired Security Chimneys International, Ltd in November 2012.

As a company who has built a reputation as one of the most trusted suppliers of quality chimney, Security Chimneys has been a great addition to DuraVent and has served to expand DuraVent’s market leading position of innovative products for the venting of residential and commercial appliances of all kinds.


In April 2013, M&G DuraVent consolidated their east coast facilities (Albany, NY and Vicksburg, MS) during a relocation and expansion to a 140,000 sq. ft. facility in Jupiter Lane, Albany.


To better serve their respective regional markets, DuraVent and Security Chimneys International are carved out of the M&G Group and begin conducting business as DuraVent / Security Chimneys focusing on the North American market.

DuraVent continues to be owned by Egeria Investments, the parent of the M&G Group.
