Haartz Canvas Topping Materials

Haartz cloth topping materials are constructed using a “three-ply” method that has an acrylic or polyester/acrylic exterior (facing) and a cloth lining (backing). The face material is woven with either a square or twill weave and the backing is either polyester, polyester/cotton or cotton. These materials are combined using an elastometric or rubber film that is sandwiched between them. This provides waterproofing and gives the material its “stretch.” Increasing the thickness of the rubber film will reduce the amount of noise in the vehicle interior. These thicker toppings are referred to as “Acoustic” and are becoming standard on most new cars.
