What Materials Block Uv. Physical Science. Ultraviolet (UV) light is invisible to the human eye, but gets a lot of attention. After all, UV light can cause sunburns, suntans, or skin cancer. It can fog photographs, make objects fluoresce, or even attract butterflies to flowers (they can see into the UV spectrum).
Referencing the table below, general purpose acrylic naturally filters all UV light below 345nm (100% UVB), but only 35% of UVA light. Simliarly, ordinary window glass passes about 90% of the light above 350nm, but blocks over 90% of the light below 300nm.
Polycarbonate is a very strong and resilient thermoplastic material. Polycarbonate is also very lightweight and capable of withstanding extreme temperatures, either hot or cold. Due to these qualities it makes for an effective roofing material for many applications. While polycarbonate roofing may not be the best option for an entire house; it
