Yes the wires are embedded in the lamination. I fitted a rear window version of this product and it must have adequately sized wiring and a relay to prevent a fire! The load is much higher than the original heated unit. I haven;t measured it but it must be in the region of 200watts/25ish amps. In addition it has a wider black edging which shows beyond the seal (at least on the rear window), much like a modern. This covers the edge of the headlining and is not visible from the inside of the car.
After 10 years it is showing sign of water ingress into the lamination (milkyness) in a small area, probably because the seal against water in the +2 rear window is so poor allowing water to be in contact with the laminated edges. Then again, my car has not been under cover for 10 years, so in typical use this is probably not a problem.
