Description

Fiberglass screen material is typically available in **0 foot rolls in varying widths, from *8 inches to **0 inches wide. Aluminum screen material is available in **0 foot rolls except the range of available widths is less than for the more commonly used fiberglass. The fineness of a screen mesh is measured in wires per inch on the warp (length) and the weft or filler (width). An *8×*6 mesh has become standard; *6×*6 was formerly common and other common sizes are *8×*8 and *0×*0.

 Fiberglass solar screens provide over *5% of UV protection, by using thicker strands and a closer mesh than regular *8x*4 fiberglass window screening. There is some reduction in visibility, but this can be advantageous, since Solar Screens are difficult to see through from the outside, while easier to see through from the inside.

Finer meshes have been developed to prevent very small insects. The finer mesh screens are also used to prevent pollens and allergens from entering homes in order to control allergic reactions.
