Fiberglass cloth is a woven material available in various sizes to allow custom strength, thickness, and weight in projects. Fiberglass cloth provides great strength and durability when layered with a resin to form a hardened composite.

Fiberglass cloth has many advantages: It has greater tensile strength than steel wire of the same diameter, it has excellent fire and heat resistance, it has exceptional thermal conductivity (making it useful for insulation applications), its chemical resistance properties are similar to glass, and it's very durable and economical.
