GAHH Tops Use Industry Leading  Haartz Acoustic Topping

GAHH uses Haartz acoustic topping material in selected models, such as the Audi A4, BMW Z4, Audi TT, Volkwagen Beetle, newer BMW 3 and 6 series, Maserati, Ferrari and others.

Acoustic topping materials are the newest in a series of developments from Haartz Corporation.  These new topping materials dramatically enhance in-cabin comfort by reducing noise levels.  Twillfast RPC Acoustic Topping canvas material, used by GAHH, provides a noticeable decibel improvement over standard topping materials.

Twillfast RPC is an acoustically enhanced three-ply composite made of acrylic twill weave outer fabric, a rubber inner layer and a polyester lining fabric.  Learn more about Haartz acoustic topping materials here.
