NO, special maintenance is not required. Keep sharp objects out of the pool and from underneath the pool.

Most people think that they're only at risk when they're outside on a sunny day, but UV light can go right through clouds, so it doesn't matter if the sky is overcast. The sun's rays are strongest between 10 am and 2 pm. Glare and reflections can give you trouble, so have your sunglasses ready if you'll be around snow, water or sand, or if you'll be driving (windshields are a big glare source).

Yes, the fabric provides a complete block from UV rays. Our optional items, our Solar Shield and "Weather Wrap?", will provide the same protection for the screen runs.

Yes, MacroBins have a UV package added to the resin which very effectively protects bins from UV exposure.

Ultraviolet (UV) rays are located just past the violet portion of the visible light spectrum; sunlight is the main source. UV light is broken into three different types: UVA, UVB and UVC. UVA has longer wavelengths and passes through glass easily; experts disagree about whether or not UVA damages the eyes. UVB rays are the most dangerous, making sunglasses and sunscreen a must; they don't go through glass. UVC rays do not reach the Earth because its atmosphere blocks them.

All PVC's degrade over prolonged exposure to excessive sunlight. Intex pools are manufactured with UV inhibitors to delay the degradation caused by sunlight.

Several safety measures protect service technicians and homeowners from eye or skin UV exposure, including a lamp shutoff switch, and a sight glass for safe and easy lamp inspection. A protective cover with a safety interlock switch immediately deactivates the lamp before the service technician or homeowner can access or service the unit. The effectiveness of germicidal UV-C is limited once molds, which are more resistant to UV energy than airborne bacteria, have already formed on surfaces.

Caviseal will burn over and change color as well as lose a 1/16 of an inch in the first month. After it burns over the degradation action slows and you will lose about an 1/8" in four months. However we want it to burn over some because it creates a hardened shell on the face increasing its permeability and moisture penetration characteristics. Back to Top

The UV rays emitted by indoor tanning lamps do not emit sufficient energy to penetrate past the skin layers. Thus, despite claims and rumors to the contrary, internal organs are not directly impacted by longer wave UV light.

Weather. Do not be fooled on a cloudy day. Be careful under haze and thin clouds. It may not be hot outdoors, but the sun's rays can still burn. Environment. You receive higher UV exposure on snow, sand, water, and concrete because these surfaces reflect UV rays. Altitude. You also get more UV radiation at high altitudes, such as the mountains, and low latitudes, such as areas close to the Equator or the Caribbean. UV rays become weaker at the earth's poles. Attire.

Yes. People with cataracts (or who've had cataract surgery), macular degeneration, and retinal dystrophies should be extra careful. Read more about these conditions in our Eye Problems and Diseases section.

The UV rays emitted by indoor tanning lamps do not emit sufficient energy to penetrate past the skin layers. Thus, despite claims and rumors to the contrary, internal organs are not directly impacted by longer wave UV light.

Absolutely. There is a growing body of well-conducted, validated scientific research demonstrating that the production of the activated form of vitamin D is one of the most effective ways the body controls abnormal cell growth. Moderate exposure to sunlight is the only way for the body to manufacture the vitamin D necessary for producing activated vitamin D.

Transitions lenses block 100% of harmful UVA and UVB rays, providing UV400 protection. In fact, Transitions lenses meet all internationally recognized standards for UV blockage including ANSI Z80.3, ISO 8980-3, EN 1836 and AS/NZS 1067. In addition, Transitions lenses were the first to receive the American Optometric Association's Seal of Acceptance for UV Absorbers and Blockers and the World Council of Optometry Global Seal of Acceptance for UV Absorbers/Blockers.

Three types of UV rays exist, including UVA, UVB and UVC. However, only UVA and UVB rays cause damage to our skin and eyes. Fortunately, UVC is absorbed by the atmosphere and never reaches the ground. Cause eye damage and are a suspect in the development of cataracts, macular degeneration and aging of the retina

Tiffen lists a wide variety of filters in the 86C size, but not a UV Protector. The closest filter available would be the Sky 1-A, a popular general use filter that will also protect your lens while absorbing about half the UV radiation, a bit more than the UV Protector. The Sky 1-A has as slight pinkish tint that adds a touch of warmth that's especially helpful when shooting in open shade or on overcast days.

far as we know - no. Only InfinityGLARE Plus can filter out the harmful ultra violet rays. All of the other waxes, polishes or sealants cannot shield your car from the harmful ultra violet rays. Waxes and polishes can even oxidize and break down under constant exposure to sun.

Almost all clothing provides some protection from the sun, but some types will protect better than others. A good way to check is to hold the piece of clothing up to a light. The tighter the weave of the fabric, the more light it will block out, and the less UV radiation that will get through. Fabric that is wet, or has a loose weave will allow more light to penetrate through to the skin.

One bad childhood sunburn doubles the risk of getting skin cancer later in life. Over 80% of a person's lifetime exposure to the sun occurs by age 18.

Currently you can find a UV sun protector at Sasha's (www.sashaskiddieproducts.com). Make sure to look for model number BR01. This UV protector is tailored to fit the Indie, Flyer, Rocket and Queen B.

Yes. They block 100% UV A&B rays - this includes the SportFlex™, Yellow, Orange and Clear lenses.

Ultraviolet (UV) light is at the invisible, violet end of the light spectrum. Even though we can't see UV light, we are exposed to UV rays from all light sources, including the sun.

No. If you are planning to be in the sun after applying Regaine® Extra Strength, use headwear. However make sure that Regaine® Extra Strength is dry before donning your hat as there is a slight chance that Regaine® Extra Strength may stain some fabrics.

Ultrasound travels through practically all solid materials as long as there are no air gaps. Porosity in a material will cause sound waves to become attenuated more than if the material is fully densified and this phenomenon can be used to quantify the densification such as for ceramics and powder metallurgy samples. In general the penetration of ultrasound in all solid materials is reduced at higher frequencies.

The structure is built from ordinary construction materials typically available almost anywhere in the world. This can include steel rods, pipe, or rebar. Other materials necessary for the project include electrical cables and epoxy or silicone sealants to protect the electric connections. While the main structure serves as the cathode, another electrode, the anode, is a special titanium mesh that does not corrode.

Grancrete has discovered it blocks a number of types of radiation because it was developed to encounter nuclear waste but the testing for UV impact is still ongoing and results will be available here in the future The data from Argonne Labs reflects that the material does not leach. Grancrete is currently seeking a independent, third party to certify this information. The structural test that has been completed is reflected in the attached data link grancrete.net/products/index.
