The spectral transmittances of these materials and the integrated transmittances in the UVB from 300 nm, UVA, visible (VIS) and near infrared ranges (NIR) were calculated. In summer in the UVB range from 300 nm methacrylate and smoked glass have the highest transmittance values (56%) and polycarbonate present the lowest (30%).
For instance, a study found that up to 74.3% of UVA radiation can still pass through smooth glass windows. Blue glass windows also transmitted up to 56.8% of UVA radiation. Curtains and shades can help cut this down, but they also block a lot of natural light. The great news is, house window tinting can help you minimize UV ray penetration. At
The amount of light transmitted depends on the type of glass you use. A high-transparency glass will let in a lot more light than a standard, tinted glazing unit. The more transparent the glass, the better it is at blocking damaging UV rays. This can be very useful for greenhouses as plants can be damaged by too much exposure to sunlight and heat. With the right material (lead) or with the right thickness for any material you are able to capture X-rays inside the material. On the other hand, you are able to transmit visible light even through metal. It's all about thickness. Gold or aluminum can be made so thin that light can pass through it.
UVA radiation makes up 95% of the all the UV rays that make it to the Earth’s surface. UVA penetrates deep into our skin and can even pass through glass. UVA damages your skin, resulting in a tan. It is the primary radiation used in tanning beds. It causes almost all forms of skin aging, including wrinkles. UVA damages the collagen and
Sheets sizes can vary from the manufacturer and some are cut from larger sheets. Because of this, the sheet dimensions are nominal and might be +/- saw cut.
