UV Ultrablock and Ultraviolet Radiation

UV - The ABC's

Energy from the sun sustains all life on earth. However, some forms of sun energy can be harmful to life. This includes the sun's burning or "ultraviolet" rays - the rays that cause sunburn and skin cancer. We cannot see ultraviolet or "UV" rays, as this form of sun energy is invisible. There are three types of ultraviolet: UV-A, UV-B and UV-C. Ultraviolet Radiation is also divided into three wavelength bands measured in Nanometers (nm ).

UV-A ( 315 - 400nm )
This is the weakest form of Ultraviolet Radiation. It causes skin-aging, wrinkles and can also damage outdoor plastics and paint.

UV-B ( 290 - 315nm )
These rays are stronger than UV-A, and are the most harmful to us and other life forms. UV-B causes skin cancer and cataracts - a permanent clouding of the eye, which reduces vision. Both UV-B and UV-A cause suntans and sunburns. UV-B also reduces the growth of plants, and may affect the health of wildlife and other animals.

UV-C ( 220 - 290 )
These rays are even stronger than UV-B, but fortunately never reach the earth's surface because they are filtered out by the atmosphere. The continued destruction of the Ozone layer can result in UV-C rays reaching the earth, and creating major problems for humans, animals and plant life. Fortunately, there are simple ways to protect oneself from UV-B. Action one takes to protect oneself from UV-B will also safeguard against UV-A (except for certain sunscreens.)

Concerned About UV Radiation?

Cooltone is the ONLY shade cloth that received the Cancer Association's seal of recognition. Cooltone shade cloth deflects more than 90% of harmful UV rays, making it the ultimate in UV protection.

SHADECLOTH

ALNET shadenet acts as a physical barrier to solar Ultraviolet Radiation and allows only controlled amounts of UVR to pass through the fabric. If the shadenet is rated at 50% blockout then it blocks out 50% (and transmits 50% and has a UPF of 2), if the shadenet is rated at 90% blockout, it blocks out 90% (and transmits 10% and has a UPF of 10), and so on.

Alnet's UV Ultrablock is a superior product that offers you great value for money.

Do not settle for anything less!
