Before you start to use RF (Radio-Frequency) / MW (Microwave) EMF/EMR (Electromagnetic Fields / Electromagnetic Radiation) blocking fabrics (or any other ELF protection-shielding) it is highly recommended to do some RF / MW EMF level testing. The RF/MW level testing in places and conditions you are going to use the fabrics will show you the levels you need to block or shield. Then you will be able to choose the right fabric that will be able to do the job and will be able to block the requested RF/MW levels.
Fabrics that contain metal fibers can block RF/MW Electromagnetic radiation. RF/MW blocking fabrics can be used to create RF/MW protection clothes, can be attached over walls as a temp RF shielding solution, can be sewed into curtains or can be used in other protection techniques. I have been using for years, long sheets of RF/MW blocking fabrics as an easy to deploy RF/MW blocking material by attaching it onto dray and wooden walls. I also used RF/MW blocking fabrics in order to create RF/MW blocking hats which I use daily. These fabrics are washable, durable and can be used for years, again and again. A large piece can be cut and trimmed and can be used for several different needs.
All our RF/MW blocking fabrics are cut off a large roll of fabric according to customer specifications. We are sorry, but return of these items is not possible.
