Glass cloth is a textile material, originally developed to be used in greenhouse paneling, allowing sunlight's ultraviolet rays to be filtered out, while still allowing visible light through to plants. The cloth is usually woven with the plain weave, and may be patterned in various ways, though checked cloths are the most common. The original cloth was made from linen, but a large quantity is made with cotton warp and tow weft, and in some cases they are composed entirely of cotton. Short fibres of the cheaper kind are easily detached from the cloth.
Due to properties of glass such as heat resistance and an inability to ignite, glass has been used to create fire barriers in hazardous environments such as inside of racecars. Its poor flexibility, and its being a source of skin irritation, made the fibers inadequate for apparel uses.
In the Southern Plains during the Dust Bowl, states' health officials recommended attaching translucent glass cloth to the inside frames of windows to help in keeping the dust out of buildings, although people also used cardboard, canvas or blankets. Eyewitness accounts indicate they were not completely successful.
