In order to prevent a premature aging due to ultraviolet sun radiation, all BAUGLAS and SOTOTHERM sheets are protected by means of a UV Absorber layer. Co-extrusion makes it possible to apply an uniform layer which filtrates ultraviolet rays.
The response to the solar radiation spectrum evidences how a UV-protected polycarbonate sheet can screens the ultraviolet component completely (on average only 4% of the radiation included in the range between 250-380 nanometers can pass through the sheet), while it remains totally transparent to the visible component. The outstanding characteristic of polycarbonate sheets remains unaltered in time. Constantly repeated laboratory tests allow issuing a warranty for the sheets against the loss of luminosity, yellowing and hailing ruptures. Please ask our offices for a copy of the warranty and of its extension.
