Films
Window films are a popular method of reducing heat, glare and ultraviolet radiation (UVR) for buildings and cars as well as for decorative and security purposes.
A large variety of window films are available and the properties of particular films depend on the intended application.
Glass
Different types of glass have different UVR transmission properties. Glass windows typically block out most UVB radiation but the amount of UVA radiation that penetrates through different types of glass can vary greatly.
Transparent building materials
Several types of plastics are used to manufacture transparent roofing. Some, but not all, plastics have good UVR blocking properties.
Assessing the sun protection properties of films, glass and materials
ARPANSA operates a service for measuring the sun protection properties of all types of films, glass and transparent plastics such as roofing materials. The UVR transmission of the material is measured and a protection factor is calculated in accordance with the published method, 'UVR Protection offered by Shadecloths and Polycarbonates' published in Radiation Protection in Australia 1995, 13 (2) 50-54. A protection factor indicates how well a product protects human skin from UVR in sunlight. For protection from artificial sources of UVR refer to Assessment of UVR Hazards.
Schedule of charges
Film testing is usually performed within 10 working days of receipt of samples, often sooner, depending on laboratory workload. Samples are processed in order of receipt.
Note that samples sent to ARPANSA for testing cannot usually be returned as the testing procedure may require the materials to be cut to size for testing.
| Number of samples | Cost per sample (including Australian GST) | Cost per sample (excluding Australian GST) |
|---|---|---|
| 1 to 10 | $219.00 | $199.09 |
| More than 10 | $186.00 | $169.09 |
Prices quoted are in Australian dollars.
