Roofing

The primary function of a roof is to present a waterproof barrier of lasting effectiveness. Flat or slightly inclined roofs have proven to be highly space economical and have therefore been applied in commercial buildings over many years. Flat roofs have now also gained acceptance in the housing market, although perception is influenced by the bad performance of early flat roofs.

The modification of roofing material with Kraton® D polymers has been a major factor in improving the quality and performance of roofing materials for flat roofs to become reputable and inspire public confidence for waterproofing of flat or slightly inclined roofs.

While these modified roofing materials have become the standard in Europe and North America in regions with hot and cold climates, the use of modification has not developed throughout the world. This section of Kraton Polymers' website aims to inform anyone on the merits of polymer-modification of roofing materials, and also focuses on recent developments related to bituminous roofing materials.
