2003-08 Audi A4 and S4 Convertible Top and Convertible Top Parts
Premium A5 German Sonnenland canvas material.
German Sonnenland Canvas is the original German made canvas used in many Mercedes, Porsche, BMW and other convertibles. An acoustically enhanced three-ply composite made of a High Tech acrylic twill weave outer fabric, a rubber inner layer and a polyester lining fabric. It's general construction is very similar to the other two canvases. It is hard to tell the surfaces apart among the three. But the manufacturing specifications make this the longest lasting top. There is an approximate twenty percent greater wear rating for Sonnenland than for Haartz Stayfast. Some of this is due to the abrasion resistance of the exterior canvas. This is a factor in certain tops where the framework design tends to produce friction between the top's surface and the car's hardware. (It is a well known 'trade secret' that the Haartz Division of Glen Raven Mills purchased the Sonnenland factory.)
Twillfast RPC Canvas is an elegant and durable canvas. The cross woven ("Dobby") weave of the inner cotton lining, together with the butyl rubber bonding between the outer canvas layer and the inner layer, provide its durability advantage. An acoustically enhanced three-ply composite made of acrylic twill weave outer fabric, a rubber inner layer and a polyester lining fabric.
