Outdoor blinds are used to combat sunlight penetration and the ill effects from it. Continuous exposure to sunlight results in interiors getting damaged. Faded colors and dried up surfaces can be seen as a result. Homes can use window coverings inside and so can most work places. However, there are a few kinds of work places where it is not possible to use window coverings inside. Outdoor window shades are used in such places.

Continuous exposure to sunlight can lead to high temperatures which can create a lot of discomfort and impact productivity in a negative manner. The use of effective outdoor window shades can help reduce costs on indoor cooling. Some establishments opt for total screening of the side of the building most exposed to sunlight. Total screening of this kind might prove to be expensive but the costs get recovered when long term internal climate cooling costs are considered.

Tough and durable material is chosen for outdoor window shades. The shades used on the exterior of a building should be able to withstand natural atmospheric changes and corrosive elements usually found in polluted urban air.

Outdoor window shades for small buildings are usually operated manually. For large buildings the maneuvering is done using means like electricity, remote controls or through computers that are linked to the overall building management system. Sophisticated models of outdoor window shades that use sun sensors and timers have also been developed.

The use of outdoor window shades does not imply total darkening of interiors. The color of the material chosen for the outdoor window shades can be such that it allows some light to filter in. If outdoor window blinds are used, the opening of the slats can be monitored to let some amount of light filter in.

Fully adjustable louvers are used to cover unusually shaped areas from the outside. The louvers may be made from aluminum or wood.

Outdoor window shades are installed after a through evaluation of the needs of the place and its occupants.
