Lambro venting products inc. was founded in 1992, in the small town of Laprairie in Québec by Mr. Jean-François Pupo in partnership with the late Mr. Edwin Berger, founder of Lambro Industries located in New-York. We started manufacturing flexible duct, in a 4500 sq. Ft plant.


In 1994, Lambro inc. expands into manufacturing plastic vents & diffusers. By 1996, the company offers an expanded line of products for the HVAC industry. In 1999, Lambro inc. moves the manufacturing facility to a spacious 53000 sq Ft plant, adding several new machinery to meet high demands from new markets.


Mr. Jean-François Pupo assumed total ownership of Lambro venting products inc. in 2009. Since 2015, we have been privileged to serve the Alberta & British Columbia HVAC industry through solid distributors. & still growing!
