Fiberglass fabrics have been developed for many marine, industrial and household purposes. There are different types of fabrics and each type has special characteristics suited to fill a specific need, as described below. Our line of Marine Fiberglass Fabrics are superior strength fabrics woven from pure glass fiber and treated with special finish processes. These finish processes are very important in that they allow the resin to wet out the fabric properly.

Beware of so-called industrial or bargain fabrics as they can be difficult to wet out and can lead to delamination. Whether you use our Marine Fiberglass Fabrics for covering or strengthening, they have outstanding tensile, structural and impact strength. We recommend them for boat hulls, cabin decks, auto customizing as well as any application where strength and durability is required.

FIBERGLASS CLOTH - Weight 3.2 oz., 6 oz. or 7 oz. per sq. yd.

Our woven fiberglass cloth is treated with a chemical coupling agent which significantly improves the peel strength and adhesion over ordinary cloth when using Epoxy-Plus resin. It works equally well with polyester resin. We recommend using one layer of our 7 oz. cloth for the hull, sides, bottom and transom for boats from 8 to 18 ft. We recommend two layers on larger boats or where additional structural strength is required. 6 oz. cloth is used for cedar strip canoes, 3.2 oz. is used for decks.

FIBERGLASS CLOTH TAPE - weight 9 oz. per sq. yd.

Fiberglass tape is woven fiberglass cloth, in narrow widths, with specially woven and bonded edges to prevent fraying. It is widely used in "stitch & glue" construction, in any area that needs reinforcement, for covering seams, or bonding edges. The tape is woven with the warp and fill yarns running parallel and at 90 degrees to the length of the tape. The tape is specially treated for use with epoxy resins, but works equally well with polyester resins.

FIBERGLASS CLOTH TAPE - BIAXIAL - Weight 12 oz. per sq. yd.

Biaxial fiberglass tape is a non-woven, double bias fiberglass cloth, in narrow widths, where the opposing layers of fibers run diagonally at 45 degrees to the length of the tape. Significantly stronger than standard fiberglass tape due to the tape weight (12 oz. vs 9 oz.) and the orientation of the fibers. Specified in some "stitch & glue" designs for heavy duty reinforcing. Coarser texture requires additional fairing for a smooth surface. Treated for use with epoxy or polyester resins.

FIBERGLASS MAT - Weight 1-1/2 oz. per sq. ft.

This specially treated material, for use with polyester resin only, is a non-woven felt consisting of chopped glass fibers 1" to 2" in length, crisscrossed and randomly interlocked, held loosely together with a binder. Since it is not woven, it can be stretched to fit into difficult areas. It is highly absorbent, soaks up a great deal of resin, and the resultant structure is stiffer than a layer of cloth, although not as strong. Mat is often used between layers of roving, or as a waterproof layer when there is no gelcoat. Typically used with polyester resin which dissolves the binder, not recommended for use with marine epoxy.

FIBERGLASS WOVEN ROVING - Weight 18 oz. per sq. yd.

Woven roving is a high strength, more coarsely woven fabric widely used in all phases of fiberglass molding. This 18 oz. treated roving has replaced all other lightweight grades where speed of wet-out, drapability and flatness of weave are important. Typically used with polyester resin but can be used with marine epoxy.
