ABOUT TRILOGY ACOUSTIC VINYL FOR BMW Z4 CONVERTIBLES

Trilogy Acoustic Vinyl was developed specifically to provide a high-quality, long-lasting topping material suitable for most types of removable soft tops. Trilogy has superior performance characteristics compared to other vinyl toppings, and the surface texture was designed to look just like the expensive twill cloth topping found on luxury vehicles like Mercedes, BMW, Audi, Bentley, and Rolls Royce.

TRILOGY is QUIET

TRILOGY Acoustic Vinyl is a 45 oz. heavyweight two-ply composite. Sounds impressive, but what this really means for you is REDUCED NOISE! In comparative tests, TRILOGY Acoustic Vinyl was shown to significantly reduce interior noise. Quite simply, tops made with TRILOGY Acoustic Vinyl will provide the quietest, most comfortable ride for you and your family.

TRILOGY is DURABLE

Trilogy Acoustic Vinyl is not just a pretty face. It is a 2-ply composite material with a heavy-duty outer layer of PVC and a 100% Polyester laminated backing. Polyester is much stronger than cotton or poly/cotton blends when it comes to abrasion and tearing. Also, polyester resists rot and mildew. Polyester is so superior, in fact, it is the only material specified for use in all European luxury convertibles.

TRILOGY is GREAT LOOKING

TRILOGY Acoustic Vinyl was designed not only to be the strongest, most durable topping vinyl available, but to be the best looking as well. The outer surface of the topping duplicates the twill weave pattern of expensive cloth toppings used in the most exclusive automobiles, such as Aston Martin, Rolls Royce, Maserati, and Ferrari. Either as a direct replacement for your original cloth top or as a fantastic upgrade from an existing vinyl top, TRILOGY Acoustic Vinyl is the best-looking, most affordable alternative.
