Far infrared heat is generated from carbon fiber strips that are attached to silver contact bus bars connected to copper electrical strips. The silver provides superior electrical current transmission while preventing arcing at contact points.
The components are then completely sealed between two plastic sheets of PET film - similar to soda bottle material, the film is thin, transparent, and very durable. All the components used making film are UL listed.
