Protection against UV Radiation
Ultraviolet Radiation – Benefits and Risks
All living creatures need light and warmth, and both are provided by the sun. But the sun also emits ultraviolet (UV) radiation.
UV radiation enhances well-being and activates the human organism. In particular it promotes the formation of the essential vitamin D3, which the body requires to build and maintain bones. But 15 minutes of indirect sunlight on the hands and face every day is often sufficient for that purpose.
The ozone layer that surrounds the earth acts as a filter against excessive UV radiation. The thinning of the ozone layer – already by about 20 percent in Western Europe – is an ongoing process due to climate change. As the ozone layer diminishes, more and more UV radiation hits the earth.
Excessive exposure to sunlight can be harmful to health, and may cause sunburn as well as more rapid aging of the skin and increase the risk of contracting skin cancer. Corresponding protective measures are therefore increasingly important.
We are exposed to the majority of UV radiation in our childhood. At this time, our UV protection mechanism is not yet fully developed. So effective protection at children’s playgrounds, for instance, is highly important.
A simple way to protect oneself against excessive UV radiation is to stay in the shade, for example under a roof. But many roofs keep out welcome light as well as UV rays. PLEXIGLAS® combines both properties, UV protection and light transmission.
UV radiation is invisible. Independent test laboratories confirm the reliable effectiveness of UV protection, however. PLEXIGLAS® is examined at the Hohensteiner Institutes according to the stringent Australian standard AS/NZS 4399:1996.
PLEXIGLAS® - whether as a multi-skin, corrugated or solid sheet – offers the highest ltraviolet protection actor for roofing materials.
PLEXIGLAS® roofing materials therefore receive the Hohensteiner quality label.
The UPF values are comparable with the well-known sun protection factors (SPF) of suntan lotions. UPF 50+ means that at least 98 percent of UV radiation is blocked.
What’s more: PLEXIGLAS® shows no yellowing! This we guarantee for 30 years.
