Active Ventilation Products Inc. (AVP) is proud to announce its twenty first year as a leading manufacturer of roof exhaust vents, intake vents & roof accessories.

A privately owned company, Active Ventilation Products Inc., key distinction has been bringing innovation to a relatively stagnant roof vent industry. Active Ventilation Products Inc. sells to distributors across the country like Beacon Roofing Supply, ABC Supply, Dave Carter & Associates and Allied Building Products, as well as major online retailers such as Home Depot, Walmart, Ebay, and Amazon.

The company is led by the original founders, brothers Martin and Ethan Kolt, and has maintained its privately-held ownership throughout its history to ensure Martin and Ethan unrestricted creativity in key business and engineering decisions. “Managing the entire process in-house from product design to production has been the cornerstone of our success over the past 21 years,” says AVP’s founder, Martin Kolt. “We have over 300 metal working machines, a full spinning department, a tool and die department, two powder coating departments, and a full staff of machine operators and assemblers in our 63,000 sq. foot building”.

Located in Newburgh, New York, Active Ventilation Products is proud to be an American based manufacturer. Ethan Kolt remembers starting out with only a handful of employees. “It’s gratifying to see that we now have over 55 employees, and an overflowing parking lot.” Says co-founder Ethan Kolt.

AVP began operations in February 1997 when the Kolt’s released the Aura Roof Ventilator™, the industry’s first roof ventilator that moved air like a roof turbine but with no spinning parts. The early success of Active Ventilation Products Inc., flagship product, the Aura Roof Ventilator, was an indicator of a growing demand for quality made roof vents.

We receive quarterly manufacturing audits, to ensure that our manufacturing tolerances on our roof vents meet UL specification. “It’s important to us that roofers and installers have confidence in our products,” states founder Martin Kolt.  For more information, please browse Active Ventilation’s website here at or call 800-roofvents (800-766-3836).
