Abstract
A non-swelling joint tape for use with drywall applications includes a tapered trim strip body extending along a central body axis and a non-swelling backing paper. The tapered trim strip body includes a first surface, a second surface opposite the first surface, a first side, and a second side opposite the first side, and is at least partially constructed from a first dimensionally stable material. The non-swelling backing paper is at least partially secured to the second surface of the tapered trim strip body and is at least partially constructed from a second dimensionally stable material. The tapered trim strip body is dimensioned such that a first thickness between the first surface and the second surface at the central body axis is greater than a second thickness between the first surface and the second surface at the first side and the second side.
