The company starts its activity in
1939 when under the name of
VETROASFALTO begins with the production of bitumen coated felts. In these years starts the production of prefabricated membranes that can be considered precursor of the actual bituminous membranes. The support of impregnated wool-paper replaces a reinforcement in glass fiber positioned in the body of a matrix made of fillerised oxidised bitumen.
VETROASFALTO have so started, in Italy to a real revolution of this technology. The stratified sequences made of coated paper felts of melted oxidised bitumen is replaced by a new application technique with torch on membranes of prefabricated rolls with high and constant characteristics.
In 1963 an italian discovery, will deeply influence the following development of the membranes with a bituminous matrix: Professor Giulio Natta, Nobel in Chemistry, develops the Isotactic Polyprophylene (IPP). From the polymerization technology of IPP the Atactic Polyprophylene(APP) comes as a natural by-product. Thanks to a VETROASFALTO's brilliant idea Atactic Polyprophylene, considered as a production waste of the more noble Isotactic, is adopted as high impact modifier for bituminous mass, and it becomes a real "compound" characterised of plasticity, high resistance to heat, high mechanical characteristics, stability, durability never obtained in the past. It is as a direct result of these experiences the first polymer bitumen membrane called
VIAPOL appeared on the market.
In 1979 VETROASFALTO moves in the modern plant of Basiano (Milan) that up to now still the company head office. All this period is important to consolidate the expansion on domestic and international markets. The typology and specificity of the products modified with APP polymers that in the meantime give to every kind of customer a wide range of choices and characteristics. Bitumen polymer membrane makes further technical improvements: membranes reinforced with woven non woven polyesters that till now have continuous evolutions, they represents the answer in terms of performances to the new building demands.
It is then possible, combining the compounds with alternative polymers of the elastomeric type, Stirene-butadiene-stirene (SBS) and ethylene-propilene-diene monomer (EPDM) to obtain a range of different products with other specific technical characteristics. The wide range of VETROASFALTO's products represents a new tangible answers to all specific requirements of waterproofing.
Today VETROASFALTO have a consolidated know-how and technology, and an excellent Technical/Marketing staff and a worldwide located customer basis.
