because it does not rust
The different types of materials used for window screen frames include aluminum, fiberglass, and vinyl.
Window frames used to be made from steel but aluminium is lighter and does not rust.
Although there is no definitive answer as to the specific materials that are used to make Armour window frames, it has been found that the majority of these are made from vinyl. This is a great advantage, as they never need painting and come in a variety of colours.
Aluminum is commonly used for flashing and for siding. Aluminum wiring for house wiring has fallen out of favor because of fire hazards resulting from improper installation and maintenance but it is still used for entrance cables.
