Why use fiberglass tape when you can cut strips from fiberglass cloth? Because this specially treated 5.7 oz. tape has selvaged edges that will not ravel when wetted out, making application easier, neater and faster. Fiberglass tape is used for protecting planking junctions and in Stitch and Glue construction for reinforcing joints. Sold by the yard.

Note: For higher speed stitch and glue hull junctions, the plans frequently call for cloth cut on a bias (at 45°) or Double Biased cloth. Using cloth installed at 45° to the axis of the juction allows all material to reinforce the joint as opposed to half reinforcing the joint and half running parallel to the joint.
