In 1969 the first Polyglass industrial production begins.
From 1972, in the Ponte di Piave (Treviso) production plant, Polyglass starts the production of bitumen polymer membranes at an industrial level and begins to export its products worldwide and in the United States.
It’s the beginning of an expansion which will be responsible for the foundation of the American Roofing Corporation in Chicago (Illinois) in 1984: the first plant in the United States.
At that time, both West American Membranes Inc. in Reno, Nevada, and Polyglass USA, in Fernley (Nevada), are born.
In 1990 Polyglass developed the ADESO® technology, a revolutionary concept for self-adhesive membranes production using a compound of APP or SBS on the upper side and a highly adhesive compound on the lower side of the reinforcement.
In 2008 Polyglass was taken over by the MAPEI Group, an international giant in the chemical industry for construction, with 90 sub-companies that operate in 57 different countries, 31 R&D centers, 10.500 employees and registered aggregate sales of 2,8 billion Euros in 2019.
In 2009 Polyglass launched the new MAPELAN® production, a new line of synthetic coverings for waterproofing which, thanks to an exclusive “multi-extrusion coating’’ technology, is able to provide FPO/TPO and PVC-P surfaces guaranteed to last long and have great performances.
In the same year the revolutionary REOXTHENE® technology, developed by POLYGLASS and MAPEI’s R&D laboratories, came to life: thanks to a groundbreaking approach, boundaries in the weight/thickness ratio have been crossed.
In 2015, Polyglass cements its position as an international player in the waterproofing solutions arena with its role in the Panama Canal project.
