24 oz woven roving is for putting the most glass down per ply on hull bottoms, transoms and heavy structural repairs. Nothing else in our fabric line adds more bulk in a single layer, and alternated with chopped strand mat it reaches laminate thickness in fewer plies.

Building the stack

Give every ply of roving a ply of mat between it and the next one. Roving bonds poorly to roving; the mat fills the gaps between the coarse bundles and ties the stack together. That mat and roving schedule is the traditional build for hull bottoms and transom cores, and it works as a backing laminate on molds.

Planning resin and wet-out

Figure on about 1:1 resin to glass by weight, which works out to roughly 2.79 oz of resin per square foot of 24 oz roving. The open weave holds air, so roll each ply firmly before the next one goes on.

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.
