High Tensile Strength: Glass is one of the strongest textile fibers, having greater specific tensile strength than steel wire of the same diameter, at a lower weight
Dimensional Stability: Low elongation under load, generally 3% or less. Glass fibers produce fabrics with excellent dimensional stability under various types of conditions.
High Heat Resistance: Glass fabrics have excellent dimensional stability under various types of conditions.
Fire Resistance: Composed of inorganic materials, glass fabrics are noncombustible, a natural choice where flammability is a concern.
Chemical Resistance: Like glass itself, fiberglass fabrics are highly resistant to attack by most chemicals.
Durability: Being inert, glass fabrics are unaffected by sunlight, fungus, or bacteria.
Economical: Glass fabrics are lower in cost than many other fabrics for smaller applications.
