The rate of fading of vinyl is less than that of normal paint and it also depends upon the shade of color being used. The lower layer is known as the substrate and has ground limestone in it to reduce the cost and maintain fluidity in the process of extrusion. Other ingredients such as butadiene and lubricants are added in order to delay the weathering of the siding.
