Bonelli Windows and Doors has joined Pella Corporation as its latest acquisition.

Bonelli has a legacy of 50 years serving architects, builders, and homeowners in the San Francisco high-end custom window and door market. Vice President of the Pella Luxury Division Cole Adrian says the west coast presence and focus on their customers is a great fit in Pella’s luxury portfolio.

“Bonelli is an exceptional business that has built a highly reputable name in the luxury market, a market in which Pella has been focused on building its presence,” said Cole Adrian, vice president of the Pella Luxury Division. “We are honored to have them be a part of Pella, to share knowledge and resources to serve the marketplace better.”

Since 1967, Bonelli has been known for its custom aluminum products with insulated barriers and been used from coast to coast in both residential and commercial projects.

Bonelli’s 25 employees will continue to work out of the main headquarters in South San Francisco and maintain its brand equity within the luxury space. Also, David Bonelli will continue to lead the company. Bonelli joins a list of Pella Corporation’s other recent luxury acquisitions, including Grabill Windows & Doors, acquired in 2015, Reilly Windows & Doors in July 2016 and Duratherm Window Corporation in November 2016. The terms of the sale will not be disclosed as Pella and Bonelli are both privately-held companies.
