(50″ wide material = approx.. 12 square foot per linear yard)
Mr. Smith wants to put an epoxy and glass covering of 1 layer of 10 oz cloth and 1101/2102 epoxy. The cabin top is 9 feet wide by 10 feet long (9×10=90 square feet). The total area to be glassed is 90 square feet.
Always consider the width of the cloth plus an overlap allowance at the seams. (We recommend overlapping all seams 1 to 4 inches.)
The cabin top width is 108 inches. Using 38 inch wide cloth, Mr. Smith needs three 10 ft. pieces. (108 in . ÷ 38 in. cloth = 2.84 or 3 pieces).
These products come in one of two types of weaves, or orientations of the fiberglass. The first is referred to as the CM or 0/90 weave. In this case, the weave goes horizontally and vertically, so, it’s stronger for things like stringers. There is also an XM version that is a +/- 45, so they have crossing 45 degree angles. This makes the glass stronger, but it does not fold and bend as easy. [links]
Carbon Fiber – Known for it’s superior strength to other fiberglass material, Carbon Fiber is an extremely popular choice. The material is very light and very durable. Carbon Fiber does not have a binder, the cloth is simply weaved together in different variations, generally called Twils. We carry a Carbon Fiber and a Combo cloth. Carbon Fiber is also the most aesthetically pleasing of the products we have.
Let’s talk Fiberglass, everyone! Here at Fiberglass Coatings, our techs know a thing or two about fiberglass and they are always looking to help. We have some different fiberglass for different jobs, so let’s cover a few of the main types. Most of these are offered in different widths and are sold by the roll or by the yard.
Woven Roving – This is a weave, where the long fibers are weaved together like a cloth. They are extremely thick and durable but are also heavier than other fiberglass materials. They aren’t used as much because they often print their pattern through gelcoat, but you will still see this glass for heavy duty items. Woven Roving is sold in 18 and 24 oz thickness. more
Mat – It’s the most basic and widely used type of fiberglass we have. The roll is a whole bunch of small fibers thrown together on a binder. There is no specific direction to the fibers, which makes them pretty universally strong and light. This is sold in anything for ¾ oz all the way up to 2 oz thickness. Mat is generally used for parts, more than anything. It’s also great for not showing fiberglass patterns through the gelcoat.

1708 biaxial (+/- 45 degree) fiberglass cloth with 3/4 oz. mat backing, ideal for tabbing, reinforcing, and repairs.
Please note: 18 oz. biaxial weave fiberglass cloth is sold by the yard; 17 oz. cloth is sold in three pre-cut lengths. All types have a 3/4 oz. mat backing that adds extra thickness and ensures a smoother finished surface. here
Biaxial fabric consists of two layers stitched together, with their fiber strands lying at +/- 45 degrees to the edges (instead of along the roll and across at 90 degrees, as with plain weave fiberglass fabrics).
Fiberglass is a composite material that includes extruded filaments of glass. The fiberglass used in the automotive industry and in boat building and hull repair is different from the fiberglass used for insulation. Rigid fiberglass can be held together with an epoxy resin. The difference in fiberglass cloth and mat is in the way it is constructed and in its appearance.
History
The ancient Egyptians and Phoenicians experimented with creating and using fiberglass. In 1880, fiberglass cloth was developed that was both durable and flame retardant. During the 20th century, fiberglass was improved and used as reinforcement in plastic laminates. When polyester resin was created, it was combined with fiberglass to form a fiberglass composite. In 1953, the first vehicle with a body made completely out of fiberglass-reinforced plastic was created, the Chevrolet Corvette.
Uses
Fiberglass mat usually comes in large carpet-like rolls and is used for automotive and boat projects. It can be used to install speakers in a car while making a mold for them, or it can be used to repair the body of a marine vehicle. Fiberglass cloth has a smoother-looking finish, excellent for water-proofing wood or other surfaces when combined with resin. Fiberglass is also used in a variety of household fixtures, like shower stalls and bathtubs.
Mat
Fiberglass mats make up most of a fiberglass body or kit. The strands of fiberglass in a mat are disorganized and can intermesh easily with the fibers of other mats, so they bond together. During construction, fiberglass mats are layered until the desired strength or thickness is achieved. Fiberglass mat has a higher density than fiberglass cloth. Cloth
Fiberglass cloth is a layer of woven strands. It is strong, with a uniform appearance, and is used where the look of a project is important. The woven fibers do not intermesh with the fibers of other layers of fiberglass cloth.
Caution
There is difference in fiberglass cloth and mat, but when working with fiberglass, use a mask designed to work with it. Always protect all exposed skin, and wear gloves. Because fiberglass is essentially tiny glass shards, if your skin comes in contact with it, it will cause irritation, itching and rashes. Also, the resin or hardener used to hold the mats and cloth together can be dangerous to inhale, especially in confined areas.
