Founded in 1972 in New Kensington, PA, Thermo-Twin’s core business was supplying window manufacturers with insulated glass units. In 1974, business expanded into general home remodeling and we began manufacturing our own windows, using frames and sashes produced by various suppliers. In 1981, our Company began selling windows under the trade name, Thermo-Twin Industries, Inc. and moved from its original location to a 55,000 square foot manufacturing facility in Oakmont, PA. This allowed for additional growth and for the window and glass operations to be housed together. In 1987, Thermo-Twin began manufacturing windows using vinyl extrusions.
1989 was a defining year for Thermo Twin. This is the year that our Company became Employee-Owned! Through an Employee Stock Ownership Plan, the employees purchased the company from its original owner. In 1997, the Technology Council named Thermo-Twin among the fastest growing technological companies in the region, and in 1998, the Pittsburgh Business Times recognized Thermo-Twin as one of the area’s 100 fastest growing companies. In 2000, Thermo-Twin became the first company in North America to purchase and install the fully automated “Super Spacer®” glass line. This space–aged technology helps reduce condensation and makes window systems that are quieter and more energy efficient than those with traditional metal spacers. Thermo Twin Windows
Thermo-Twin achieved another milestone in 2004, by offering customers state-of-the-art patio room enclosures. In 2005, Qualified Remodelers Magazine listed Thermo-Twin 59th of the top 500 remodeling companies in the country. In 2006, Qualified Remodelers Magazine listed Thermo-Twin 45th of the top 500 remodeling companies in the country and 35th in the top 200 specialty remodeling companies in the country. In 2007, Thermo-Twin was listed in The Top 100 Manufacturers by Window & Door Magazine. During 2008 & 2009, Thermo-Twin Industries, Inc. overhauled its vinyl window lines to welded frames with optional welded sashes. Today, Thermo-Twin’s employee owners continue to lead the industry in manufacturing and installing the best windows, doors, sunrooms and siding. In January of 2017 the local Toledo Branch of Thermo-Twin has changed its Sales and Operations from being factory operated out of Pittsburgh to local owner Mark Wurzinger. Mark & his Sales Manager Kelly Cartwright have over 30 years representing Thermo-Twin windows and over 65 years in the window industry. The local branch is now TTT Windows dba Thermo-Twin Toledo.
