About 1 cm under your rug. No wires to overheat, no fan, no glowing element: a film that warms evenly over its whole surface.
Any ordinary rug: wool, cotton, jute. It covers the underlay completely and radiates the warmth.
1 mm, 250 g/m². Protects the film and spreads the warmth evenly.
Carbon stripes between copper busbars turn electricity into far-infrared warmth at 220–260 W per m². Laid in strips so the underlay rolls up without cracking.
Sends the warmth up into the rug instead of into cold tiles.
We cut the underlay to the rug’s measurements, so the edges line up and nothing shows. Three standard sizes; any other size on request.
Certificates and test reports are available on request.
Household appliance electrical safety: insulation, leakage, temperature limits.
No interference with Wi-Fi, TV or anything else at home.
Free of restricted hazardous substances.
Every underlay is switched on, measured and checked before it leaves Cascais.
The underlay barely self-regulates: while it is on, it draws close to full power. That is why we quote costs at full power, and why a plug-in thermostat (not included) is the way to cap temperature and consumption.
Store it rolled at 20 cm or more across. A sharp fold breaks the film.
Your rug, yes. Mattresses, duvets or foam on top trap the heat.
Sofas and desks are fine; heavy furniture on thin pointed legs is not.
No bathrooms, balconies or steam cleaners.
Plug straight in; no coiled cable reels.
Built for continuous use. Unplug when away for days.
