Description

Fiberglass is a natural insulator because it does not conduct heat and cold, and it doesn't expand or contract. Most window and door frame components have an interface of different materials: glass on wood, glass on aluminum or glass on vinyl. With fiberglass, the components are identical which means there is minimal expansion and contraction and if there is any, the components expand and contract as a unit.

Fiberglass windows are manufactured using a pultrusion process where glass fibers are coated with resin and pulled through a hot die the shape of the frame or sash profile. The heat cures the fiberglass resin to form a permanent shape that remains unaltered by any environmental condition. This strength means pultruded fiberglass window frames and sashes can be narrower, providing more window viewing area, which, in turn, means greater heat gain.

Fiberglass windows and doors is a new type following wood, steel, and aluminum, plastic material, not only have the same anti-corrosion, heat preservation and energy-saving performance, but also own unique performance. It is without expansion or contract under direct sunlight and cold climate; light weight and high intensity, no need metal reinforcement; long service life. Its combination property is better than other type of doors and windows. it is been called” green products” in *1st century because of the excellent features and beautiful appearance.
