Fiberglass Mat VS Cloth

Fiberglass is a composite material consisting of extruded glass strands. The fiberglass used in the automotive industry, shipbuilding, and hull repair differs from the fiberglass used for insulation. Rigid fiberglass can be bonded together with epoxy resin, which provides strength and durability. The difference between fiberglass cloth and fiberglass mat lies in their construction, appearance, and applications.

What's The Differences Between Fiberglass Mat & Cloth?

Choosing between fiberglass mat vs cloth is critical for achieving the best results in your project. Both materials have unique properties, and understanding their differences helps you decide which suits your needs. Whether you require fiberglass cloth for strength and precision or a chop strand fiberglass mat for conformability, the right selection ensures optimal performance.

What Are Fiberglass Mats and Fiberglass Cloth?

Fiberglass Cloth Roll:

Fiberglass cloth consists of layers of woven fibers in a tight and uniform pattern. This woven cloth is durable and has a consistent structure, making it ideal for applications where strength and appearance are vital. Weave styles like plain weave or harness satin enhance the cloth’s structural properties. The warp and fill yarns in the weave pattern provide additional strength and stability, ensuring durability in demanding conditions.

Fiberglass Mats:

Fiberglass mats are composed of randomly oriented fibers held together by a resin binder. For example, the fiberglass chopped strand mat offered by Heaterk uses a needle-punching process, enhancing strength and reducing environmental impact. Compared to older methods using a polyester and vinyl ester resin binder, needle-punched mats are adhesive-free and can withstand temperatures of up to 550 degrees Celsius.

Differences Between Fiberglass Cloth and Mat

Fiberglass cloth and fiberglass mat are widely used in various industries due to their high strength, low weight, and corrosion resistance.

• Fiberglass Cloth: Made by weaving glass fibers into a tight, uniform weave pattern, this material offers tensile strength ranging from 300 to 500 MPa, making it ideal for applications requiring high performance, such as automotive and aerospace parts.
• Fiberglass Mat: This non-woven material, also known as a chopped strand mat, features randomly oriented fibers for better conformability in complex geometries. It has moderate tensile strength (100 to 200 MPa) and is commonly used in boat hulls, architectural structures, and other applications requiring impact resistance.

When deciding between fiberglass mat vs cloth, consider the build thickness, conformability, and performance requirements of your project.

When to Use Fiberglass Mat and Fiberglass Cloth Rolls?

If your project requires strength and precision, fiberglass cloth is the right choice. Its multi-directional warp and weft weaving process results in high strength and a lighter material. Fiberglass cloth rolls are perfect for lightweight applications or as raw materials for coated fiberglass fabrics.

For applications requiring heat or sound insulation, fiberglass mat is more suitable. A fiberglass needle mat offers better sound and heat insulation compared to woven cloth. Its thermal conductivity can reach 0.112W/m·k, and it achieves a Sound Absorption Coefficient of up to 0.98 at 4000 Hz. Whether you choose fiberglass mat and fiberglass cloth, understanding their unique benefits ensures the best results for your project.

Where to Use Fiberglass Mats and Fiberglass Cloth?

The key difference between fiberglass mat and fiberglass cloth lies in their build thickness, strength, and applications.

• Fiberglass chop strand fiberglass mat: Suitable for large spaces, such as machinery, pipes, walls, and roof insulation.
• Fiberglass cloth rolls: Compact and ideal for applications with space constraints, such as hull insulation, waterproofing wood, or sealing surfaces requiring added strength.

Combining fiberglass mat and fiberglass cloth is also a practical solution for projects that demand both heat and sound insulation while maintaining cost efficiency.

How is fiberglass fabric made?

Our fiberglass cloth rolls are available in various weave styles, including plain weave, four-harness satin, and eight-harness satin. These fabrics, such as the popular 4 oz, 6 oz, and 10 oz plain weaves, are easy to handle and resistant to fraying. The warp and fill yarns in the fabric provide superior durability, even under demanding conditions.

The fiberglass chopped strand mat uses a needle-punching process that ensures the fibers intermesh effectively, creating a strong bond across multiple layers. This technique allows for the desired build thickness and ensures a denser material compared to fiberglass cloth. Chop strand fiberglass mat is particularly effective in construction projects where added density is essential.

Which fiberglass fabric should I choose?

The fiberglass mat and fiberglass cloth from Heaterk are made of E-glass, an electronic-grade material designed for durability and performance. With over 20 years of experience, Heaterk provides high-quality fiberglass fabric certified by UL723 and ASTM E84 standards. For tailored solutions, including the HKBDZ series glass fiber needle felt, Heaterk offers cost-effective options for your specific project needs.
