Information
on the resistance of Alnet's UV Ultrablock Shade Cloth: How
much UV reaches you?You
get more UV, and sunburn faster, when the sun's rays are stronger. The amount
of UV depends on: The
time of day:
UV
is greatest at midday (when the sun is highest in the sky), and less in early
morning or late afternoon. The
season:
UV is greatest in the summer, less
in spring and fall, and least in the winter. Cloud
cover:
A thick, heavy layer of cloud blocks
UV. Puffy, fair-weather clouds or layers of thin, light cloud let most of it through.
The darker the clouds, the less the UV. Be careful under thin clouds - the sun's
rays don't feel as hot, but they can still burn. The
type of surface you are on:
You get much more
UV on snow, since the white surface reflects the sun's rays back onto your skin,
just like a mirror. Fresh snow reflects the greatest amount of UV, while other
bright surfaces, such as dry sand and concrete, reflect less. Your
elevation:
You get more UV on a mountain than
at lower elevations, as the air is clearer and thinner. Where
you are on the earth's surface:
UV is strongest
at the equator, and gets weaker as you go towards the earth's poles. The poles
receive the least UV. If you live in southern Canada, you will receive more UV
than if you live in the Arctic. What
Shadenet you are under:
Select the proper protection.
The sun delivers the most UV when it is high overhead at midday in the summertime.
A good rule of thumb is: "if your shadow is shorter than you are, you should protect
yourself from the sun." Don't
confuse temperature and UV. Light cloud, or a breeze, can make you feel cooler
- but they don't reduce the UV. Alnet's
UV Ultrablock is a superior product that offers you great value for money. Do
not settle for anything less! |
