The History of Polyglass

Polyglass was founded near Venice, Italy, in 1960 by brothers Luigi, Romano, and Antonio Zanchetta. Decades of practical experience as roofing professionals provided the Zanchettas with a strong foundation for developing contractor-friendly roofing and waterproofing materials.

By the 1970s, Polyglass had solidified itself as a leading manufacturer of modified bitumen roofing membranes in Europe. The company began exporting and distributing products to the U.S. in the 1980s. In 1992, the Zanchettas took another big step forward by opening Polyglass’s first U.S. facility and headquarters.

Since then, Polyglass has become a leading innovator in the roofing industry. In the late 1990s, the launch of Polyglass’ patented self-adhered ADESO® Technology — the first self-adhesive membrane introduced to the United States — positioned Polyglass as a leader in self-adhered modified bitumen membranes.

After joining the Mapei Group in 2008, Polyglass U.S.A. moved its headquarters to Deerfield Beach, Florida. To this day, the company remains a family business, with Natalino Zanchetta — the son of founder Romano Zanchetta — at the helm in his role as President/CEO.

Polyglass is proud to celebrate 30 years of evolution and innovation in manufacturing in the U.S. As part of the company’s commitment to continuous improvement, it recently launched a new liquid-applied membrane system called Polyglass PMMA. Polyglass has also entered the Building Envelope market, offering a comprehensive selection of high-quality products and systems to provide for all specifications and requirements.

Polyglass Through the Decades


  • Starting as roofing contractors, brothers Luigi, Romano, and Antonio Zanchetta realized on the job that there was a need for more contractor-friendly roofing products. After years in the field, the Zanchettas decided to put their beliefs into action and created their first compound formulation. Joining “poly” from polymer and “glass” from fiberglass — two elements in their products, the name Polyglass was born.


  • In 1972, Polyglass’s first plant was built in Ponte di Piave, a town just north of Venice, Italy. The location was chosen because it was home to the Zanchetta family.

  • By the mid-1970s, two production lines were up and running, producing modified bitumen roofing membranes. The business grew from Italy to the surrounding countries.


  • The start of the 1980s was an exciting time for Polyglass as Romano decided to venture into the United States business opportunity. With the growth of Europe’s business, expanding abroad was a natural progression.
  • By the mid-1980s, American Roofing Corporation was distributing Polyglass products in the mid-western United States with great success.
  • In the late 1980s, Polyglass invested in West America Membranes, which had a manufacturing facility in Fernley, NV. The company ceased operations allowing Polyglass to buy the plant and its contents.


  • After buying the manufacturing plant in Fernley, Polyglass made its own facility by bringing its knowledge of building state-of-the-art manufacturing equipment to make top-quality products. Polyglass opened its first U.S. facility and headquarters in 1992.
  • 1997 marked 25 years since Polyglass entered the roofing manufacturing business and celebrated by bringing all of its sales reps from the U.S. to Italy to show off the company’s roots. 1997 also marked the year Polyglass opened its second U.S. manufacturing plant in Hazleton, PA.
  • At the end of the 1990s, Polyglass modified its logo by incorporating the Q behind the company name. Q, standing for quality, was the recognition of Polyglass SpA achieving ISO 9001. At the same time, Polyglass introduced the first self-adhesive membrane in the United States – creating a new product category within the Asphalt Roofing Manufacturers Association (ARMA).


  • At the turn of the century, Polyglass SpA experienced significant growth, opening multiple distribution points with main locations in Great Britain and Romania. Polyglass SpA expanded its operations in Ponte di Piave to support this growth.
  • In 2003, Polyglass revolutionized the roofing industry by manufacturing its self-adhered membranes with its patented ADESO® Technology. A dual-compound formulation allows the contractor to have multiple surface options on an aggressive self-adhesive bottom layer.
  • In 2007, Polyglass opened the doors of its third U.S. plant in Winter Haven, FL. The following year Polyglass introduced coatings to its product offering. Manufacturing its own coatings, cement, mastics, reflective coatings, and elastomeric roof coatings, Polyglass applies the same commitment to quality to this product category.
  • In 2008, the Mapei Group acquired Polyglass. A company heavily focused on product research and development. Mapei has been in the building materials industry for over 80 years and is owned by an Italian family, making it a natural fit for Polyglass.
  • Polyglass launches its most recent technology to the roofing industry, CURE Technology®. This innovative, patented technology features infused ceramic microspheres, ultraviolet stabilizers, and proprietary resins resulting in a longer-lasting, environmentally-friendly, higher-quality modified bitumen membrane.


  • Polyglass moved its U.S. headquarters to Deerfield Beach, FL, in 2010. With three plants across the U.S., Polyglass continues to develop its ability to service the Americas. Combined with its strong European operations, Polyglass is a global company that provides quality roofing products featuring cutting-edge technology.
  • In 2014, Polyglass U.S.A., Inc. acquired KM Coatings to increase its footprint in manufacturing roof coatings. The acquisition resulted in a fourth U.S. manufacturing facility in Phoenix, AZ.
  • In 2016, CISQ/CERTIQUALITY S.r.l. recognizes Polyglass for its Quality Management System Meeting ISO 9001:2015 Standards for the Design, Manufacture, and Sales of Modified Bitumen Roofing and Waterproofing Membranes, Coatings, Adhesives, and Sealants.
  • In 2017, Polyglass U.S.A., Inc. opened its fifth manufacturing plant in Waco, TX.
  • In 2019, Polyglass introduced TurboSet, an innovative two-compound, water-based, liquid-applied roof coating system featuring our Blue Cure Technology additive, which speeds up drying and curing time.
  • In 2019, Polyglass announced SEALLap® ULTRA – The next generation of SEALLap Technology. The newly redesigned manufacturing process applies a self-adhesive (SA) compound to the side lap of the membrane for an instant bond, tested stronger than all other application methods.


  • Celebrates 30 Years of Evolution and Innovation manufacturing in the US.
  • Launches new liquid-applied membrane system: Polyglass PMMA.
  • Polyglass joins the Building Envelope market offering a complete range of superior products and systems to provide for all structural waterproofing requirements.

With Polyglass ADESO® Technology, the Modified Bitumen Membranes feature a unique self-adhering technology that eliminates the need for open flames and hot asphalt.


An essential component of any steep-slope roofing system, Underlayments act as a secondary barrier to protect the roof from water infiltration and other external elements. Polyglass self-adhering Underlayments are designed with advanced technology to provide protection against wind-driven rain, ice dams, and snow. This technology saves contractors time and money on installation costs.

Elastomeric Roof Coatings
