## Long description

Thermoval Folia F4 single-sided powered under-mirror 400×500 mm is a heated film panel designed to be installed behind mirrors and similar flat surfaces to provide localized warming that prevents fogging and reduces condensation. The compact 400×500 mm size fits many bathroom and dressing-room mirrors and delivers targeted surface heating when connected to a compatible electrical supply. The heating film is intended for indoor use and provides a discreet anti-fog solution without altering the mirror surface.
Advantages
The Thermoval Folia F4 offers rapid and even warming across the film area to maintain a clear reflection and limit moisture accumulation. Its single-sided powered design simplifies installation behind a mirror, while the flat, low-profile panel remains unobtrusive and does not affect the mirror’s visible surface. The solution is energy-efficient for localized anti-fog use and compatible with standard indoor electrical installations when installed according to applicable electrical standards.
Suitable for
 Bathroom mirrors above washbasins where steam causes fogging
 Dressing-room or makeup mirrors to maintain a clear reflection
 Indoor mirrors in sauna anterooms, gyms, or hotel rooms
 Retrofit installations where localized anti-fogging is required

How to use
