Woven roving is coarse, heavy fabric woven from untwisted glass bundles, and at 24 oz per square yard this is the most bulk you can put down in a single ply. It is the traditional hull-bottom and transom-core fabric: alternate it with chopped strand mat and you build a thick laminate fast, with the mat filling the coarse weave and tying the plies together.

Where it goes: hull bottoms, transom cores, heavy structural repairs, mold backing laminates.
Run it between mat layers. Roving does not bond well roving-to-roving; the mat is what makes the stack work.
Resin demand: roughly 1:1 resin to glass by weight, about 2.79 oz per square foot.
Thread count: about 5 by 4, 0/90 woven orientation.
Width: 50 in, cut from 1 yard up to a full roll.

The coarse weave traps air. Roll it hard and expect to work resin up through it rather than down into it.

What To Expect When You Order Fabric Rolls

Is woven roving flexible?

It’s relatively stiff compared to other fiberglass fabrics, but it can still conform to gradual curves with proper wet-out and pressure.

Can I layer woven roving with other fiberglass materials?

Yes, and you usually should. Woven roving builds thickness fast but has a coarse weave, so it is almost always alternated with chopped strand mat: the mat fills the weave and ties the layers together for a stronger, void-free laminate. A common schedule is mat, roving, mat. Finish with cloth or mat for a smoother surface.

What resin should I use with woven roving?

Woven roving works well with polyester, vinyl ester, and epoxy resins. Polyester is common in boatbuilding, while epoxy is preferred for repairs and higher strength applications.

What is woven roving fiberglass?

Woven roving is a heavy-duty fiberglass fabric made from continuous strands woven into a coarse, crisscross pattern. It provides high tensile strength and is ideal for structural laminates in marine and industrial applications.

How is woven roving different from fiberglass cloth?

Woven roving is much thicker and heavier than standard fiberglass cloth. It’s used for strength and bulk, while cloth is typically used for finishing or lightweight laminates.
