Fiberglass Cloth Manufacturer, Supplier & Exporter in India
Fiberglass cloth is a fabric that is woven using high-quality glass fibre yarns as reinforcements and insulations. This fabric is characterized by mechanical strength, dimensional stability, resistance to thermal conditions, and suitability with resin systems. Applications of fiberglass cloth include electrical insulation, composite production, production of transformers and coils, production of motors and generators, high-temperature operations, and other industrial applications.
Harnawa Insulations produces fiberglass cloth produced using untwisted “E” glass yarn with surface sizing or resins. Woven glass fibre roving fabric is produced to cater to applications needing reinforcement, thermal properties, and processing ease. The latest specification of the Harnawa product is a temperature range of up to 550°C and natural white colour.
Being experienced fiberglass cloth producers in India, Harnawa offers fiberglass cloth-based insulations and reinforcements to industrial clients. Harnawa also produces a wide variety of electrical insulations, which include fiberglass cloth insulation sleeves, fiberglass tapes, insulation papers, laminate insulations, and other electrical insulation parts.
What Is Fiberglass Cloth?
Fiberglass Cloth is a woven fabric manufactured through glass fibre yarn. The glass fibre yarns are interwoven to form a sturdy and stable fabric construction. Depending on the construction type and its use, the fiberglass cloth can be used as electrical insulation fabric, reinforcement fabric, thermal insulation fabric or as part of the laminate composite materials.
Unvarnished fiberglass cloth by Harnawa is a woven glass roving fabric using heavy untwisted “E” glass yarn. The glass yarn has a resin compatible size or surface treatment that makes it appropriate for use in resin system and laminate composite materials.
In contrast to ordinary textile fabrics, the fiberglass cloth is meant for industrial applications where high mechanical strength and heat resistance are needed.
How Is Fiberglass Cloth Made?
Fiberglass fabrics are made by weaving the yarns made of glass fibers to make fabric. The choice of the yarns, the weaving process, weight, thickness, and surface dressing depends on the end use of the fabric.
In Harnawa’s unwaxed fiberglass fabric, heavy untwisted “E” glass yarn is woven to make a roving fabric out of glass fiber. A surface dressing that is compatible with resin helps the fabric to function well with resin.
This fabric has the advantage of both woven fabric and glass fibers.
Key Features of Fiberglass Cloth
The following are some of the properties associated with the use of fiberglass cloth.
- Mechanical strength
- Thermal stability
- Dimensional stability
- Compatibility with resin
- Reinforcement ability
- Lightweight construction
- Handling ability
- Suitable for composite laminates
- Suitable for electrical insulation purposes

Harnawa identifies mechanical strength, thermal stability, and cost-effectiveness as some of the major properties of its unvarnished fiberglass cloth.
Fiberglass Cloth for Electrical Insulation
The fiberglass cloth has been applied in electrical insulation systems that require both physical strength and thermal stability. The fiberglass cloth will provide reinforcement as well as retain properties suitable for insulation applications in industry.
The fiberglass cloth has application in transformer and coil fabrication, motor fabrication, generator fabrication, high temperature applications, electric vehicle applications, and capacitor fabrication. These are some of the uses of the fiberglass cloth listed by Harnawa for the product.
Harnawa provides a range of fiberglass electrical insulations other than the fiberglass cloth and includes fiberglass tape and fiberglass insulation sleeves.
Fiberglass Cloth for Composite Laminates
Composite laminate manufacturing is among the most significant uses of woven fiberglass cloth.
Fiberglass roving may be mixed with resin to manufacture composites that are reinforced. As compared to some kinds of chopped strand mat, woven roving is capable of wetting out faster and delivering better physical characteristics in the laminate. According to the product description by Harnawa, the materials normally used in composite laminates include woven roving that is usually mixed with chopped strand mat.
This kind of laminate may offer valuable attributes.
10 oz Fiberglass Cloth
10 oz fiberglass cloth is a popular search term for fiberglass fabric. “Oz” usually stands for weight per square yard of the fabric, and that is why 10 oz fiberglass cloth can be referred to as a medium weight fiberglass fabric.
In choosing 10 oz fiberglass cloth, one should take into account all the technical specifications of the fabric such as its composition, yarn, weave, width, resin compatibility, temperature needs, and use.
If the industrial requirements are needed, it is advised to check the needed fabric weight and other technical specifications with the supplier.
4 oz Fiberglass Cloth
4 oz fiberglass cloth is an alternative type of fiberglass cloth that is utilized in cases where flexibility, handling, and weight reduction of material are the key factors. It may be taken into account for those situations where the weight of the reinforcement layer needs to be reduced.
Whether the usage of 4 oz fiberglass cloth is possible depends on the mechanical properties, laminate structure, resin system, temperatures, and applications.
When ordering quotations, customers have to provide the information about the weight of fabric, width, thickness, weave, and application of fiberglass cloth.
Fiberglass Cloth Thickness
Thickness of fiberglass cloth is determined by yarn structure, weight of the fabric, weave and manufacturing specification.
When choosing thickness of fiberglass cloth, following parameters should be taken into account:
- Required mechanical strength
- Requirements to electrical insulation
- Temperature of operation
- Compatibility of the fabric with the resin
- Requirements to flexibility
- Thickness of laminate
- Method of application
- Required weight of fabric
- Width and dimensions of the roll
While buying fiberglass cloth, the buyer should not pay attention only to its thickness but should take into account all material specifications and its intended application.
For those applications where the use of rigid fiberglass insulation components is required, Harnawa also offers G10 Glass Epoxy Sheets made of woven fiberglass cloth and epoxy resin.
Fiberglass Cloth Roll
A fiberglass cloth roll is an effective method of packaging by manufacturers and industries that need rolls of cloth continuously in their manufacturing processes.
Roll-formed fiberglass cloth can be effectively used in manufacturing composites, insulation wrapping, reinforcing, and various other industrial applications.
The specifications of roll width, cloth weight, thickness, weave, and quantities should be verified prior to making any orders. The Harnawa website states that their material is woven glass fibre roving fabric and encourages customers to contact them regarding their needs.
Aluminum Foil Fiberglass Cloth
The aluminum foil fiberglass cloth is a combination of a fiberglass fabric reinforcing material with aluminum foil. The use of this type of construction will enable situations where reinforcement properties of fiberglass are needed, as well as the properties of aluminum foil.
Aluminum foil fiberglass cloth could be considered where heat shielding, insulation, ducting, industrial protection and other such applications are needed.
The exact construction and performance of the material will depend upon the nature of the fiberglass fabric, the thickness of aluminum foil, the bonding technique, and other application details. It is therefore recommended that buyers specify the aluminum foil fiberglass cloth construction while asking for quotations.
Where fiberglass based insulating material is required, Harnawa also offers fiberglass insulation sleeves and fiberglass tape.
Applications of Fiberglass Cloth
Fiberglass cloth can be utilized within several industrial applications because of its strength, temperature resistance, and versatile applications.
