Description
It is a waterproof sheet installed behind the mirror which prevents the accumulation of steam on the front. Therefore the mirror remains clean and fog free, but it only works on the surface covered by the back sheet.
Depending on the mirror´s dimensions, one or more sheets can be attached in order to get a bigger fog free surface.
When the heating sheet is connected to the mirror´s circuit, it will get switched on and off together with the lighting.
