Our history

The spirit of Polyglass has deep roots and began with the hard work of three brothers who committed themselves to the production of roof coverings since 1960: at that time, the brothers founded their first company specialized in waterproofing, which in a short time employed 30 employees and expanded all over Italy.

Our Group boasts around 300 employees all over the world and plants in Italy and USA: at the end of 2019 Polyglass turnover reached 350 million of euro.



From an artisanal
to industrial production

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.


The opening to foreign markets

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.



Scientific research to offer new,
simple and effective solutions

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.


Becoming part of the Mapei Group

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.



Revolutionary technologies for
international projects

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.
