The purpose of these fabrics are to provide shielding from radio frequency EMF. While they may not provide complete protection, then can significantly reduce them. It is always recommended to measure RF exposure before and after an installation to see if a desired level is reached. The fabrics are mostly sold by linear feet or meter. There are also a couple of pre-cut options available called “seamed panel”. There are several types available depending on the purpose, such as for clothing versus curtains.
