Conformable and Lightweight Fabric for General Use

This 4-ounce Plain Weave Fiberglass Fabric is our most popular selection for use as a surface fabric, with enough body to be easily handled. This fiberglass wets out to a transparent, protective barrier, and can be used to prevent print-through of heavier fabrics underneath. It is often chosen for strip-built canoes and final layering over moldless designs.

Like other plain weaves, it delivers uniform strength in both horizontal and vertical directions, with warp and fill yarns at 0 and 90 degrees, respectively. 


  • Most popular surface fabric
  • Uniform horizontal and vertical strength
  • Minimize print of laminate fabrics
  • Cures transparent


  • Ideal for a final layering over moldless designs
  • Great for building cedar or strip-built canoes and kayaks
  • Orient this fabric so that yarns run parallel to expected loads.
  • During lay-up, add layers at alternating 45-degree angles to maximize strength.
  • Use with epoxy resin, polyester resin, or vinyl ester resin to produce composite parts of excellent strength, low weight, and great cosmetics.

Folded prepacks are typically shipped in a small box, or packaged in a box with other items on your order. Rolled fabrics ship in a long (45", 53", or 62") box. Click below on the "What to expect when you order Fabric" video to see how rolled fabrics are cut and shipped each time you order.


4 oz Fiberglass Fabric This fabric is sold by the linear yard, either as a prepackaged quantity or by continuous yardage. Prepacks This fabric is available in pre-cut lengths that measure one yard (#262-F, folded package), three yards (#262-B, folded package), and five yards (#262-C folded package). Each is packaged and sold separately. For your convenience, these "prepacks" can be purchased in any combination. However, if the length for any one fabric totals 10 yards or more, we suggest you purchase it in continuous, "cut to length" yardage. Continuous, "Cut to Length" Yardage If you know in advance that you intend to purchase 10 yards or more of any one fabric, it should be ordered in continuous, "cut to length" yardage. In this case, fabric will be cut once according to the total yardage ordered, and customers receive a price-per-yard discount as compared to prepacks. Quantity discounts continue to deepen as the yardage increases for any one cut of one fabric.

Boat glass 3yd order

May 11, 2023  |  By Bob

Received what was ordered quickly and it was well packaged and good quality weave. Only downside is shipping cost. Seems a little high for a product that can be shipped in a large envelope. Otherwise I'm happy with my purchase and will buy from Fiberglast again.

Great stuff

I did not expect it to be shipped so quickly, it was well wrapped and package well.
