Caravan foil heating is specially designed to be installed directly under the flooring. It is ideal for installation on the base layer of the floor of the caravan or camper van. The top layer of flooring is then laid on top. An insulating layer is laid underneath the foil, improving efficiency still further. The heating effect builds up gradually and will raise the temperature of the caravan floor by approximately 8 to 10 degrees Celsius compared with a non-heated floor. The foil is supplied with a safe, 42-volt electrical system and with a capacity of 100 watts per m2.
