Text~SOLAR SHADE FILM FOR ROLLER BLINDS/SCREENS

Special ultra violet inhibitors ensure all solar shade film rejects 99 % of Ultra Violet Light.

It is important to remember that solar film does not claim to totally eliminate fading, only to help reduce fading from the sun's U.V. rays by slowing down the process. The expectation from testing, using blue wool standards, is that the fade rate is usually halved or better.

Many other factors contribute to fading and some of these factors may be more likely to cause a fading problem.

Fading due to visible and infra-red radiation are together about equal to fading caused by ultra violet light. Some materials are more susceptible to ultra violet light whilst others are more susceptible to visible and infra red radiation. Some items will be affected more by the visible light and infra red radiation, rather than the U.V. light. Heat, poor dye anchorage and internal factors such as fluorescent tubes or spot lighting should also be considered.

Ultra violet light rays can bounce off solid objects - buildings, trees, streets, etc. Therefore, regardless of UV direction, there can still be a fading problem.

A test is simply to place a sample of fabric or the item to be tested near a sunny window and cover half with the solar film. Repeat this process using the various colours of film if necessary. After about one week there should be a difference in the shade of the fabric that was not covered.~~~13437~13442~~
