Flexel Mirror Demister Pads (300–700 mm Wide) are ultra-thin, self-adhesive electric heating mats designed to sit discreetly behind bathroom mirrors and prevent condensation build-up. By gently warming the glass surface, they keep mirrors clear even after hot showers, providing an instant, energy-efficient reflection without wiping or streaks.
Ideal for bathrooms, en-suites, shower rooms and cloakrooms, demister pads are one of the simplest comfort upgrades you can add to a modern bathroom. They operate silently, use minimal electricity, and are commonly wired into the lighting circuit so they switch on only when the room is in use.
How Mirror Demister Pads Work
A low-wattage heating element warms the mirror slightly above room temperature. Because condensation forms on cooler surfaces, this gentle warmth prevents moisture from settling, keeping the glass clear without excessive heat or energy use.
For larger mirrors, multiple pads can be installed together to ensure full coverage across the reflective surface.
Simple Installation for New or Existing Mirrors
The self-adhesive backing allows installation on both new mirror projects and existing bathroom mirrors. Pads are typically connected to the lighting circuit or a switched spur so they operate only when required.
Important safety notes:
- Mirrors with metallic or conductive foil backings must be earthed due to potential capacitance effects.
- Keep pads away from holes or cut-outs to avoid mirror stress cracking.
- Grounding pads are available at minimal cost if required.
