What Duravent Group does

Duravent Group is a privately held, PE-backed climate technology company that designs and manufactures venting, filtration, and air-control systems for residential and commercial construction. Its portfolio spans 14 wholly-owned brands — including Duravent, Hart & Cooley, Selkirk, Amerivent, Security Chimneys, AMPCO, Heatfab, AirMate, AmeriFlow, Lima, Milcor, Portals Plus, RPS, and the 2024-acquired Builder's Best — plus three strategic partner brands (Menzies Metal, PrimexVents, RUTLAND). Products include chimney and factory-built venting systems, Type B gas vents, dryer venting, specialty gas vents, commercial pressure stacks, roof curbs and flashings, and HVAC grilles/registers/diffusers. The technology base is fundamentally physical — UL/ULC-certified metal and polypropylene venting assemblies with proprietary twist-lock and snap-lock connection systems — augmented by 1,000+ SKUs and 15+ patents concentrated in dryer venting.

The company monetizes through B2B hardware sales across three channels: a direct commercial sales force targeting general contractors, architects, and specifying engineers; a residential sales team and the new myDVG customer portal serving contractors, homebuilders, and installers; and retail partnerships with Home Depot, Lowe's, Menards, Ace Hardware, Tractor Supply, True Value, and Do it Best for DIY and prosumer demand. Customers span three end-segments — residential pros/homebuilders, commercial construction, and retail/DIY — across the US, Canada, and Mexico, supported by 15 manufacturing and distribution locations.

Ownership rests with Bain Capital's Special Situations team (since March 2026) alongside existing investor Egeria and company leadership. The company is currently executing a build-out, evidenced by recent senior hires (CIO, VP Ecommerce, VP Supply Chain, VP Residential Sales), the launch of the myDVG digital portal, and stated intent to expand the platform through organic investment and strategic acquisitions in venting, filtration, and air quality.
