Thermoflex underwood heating mat systems are perfect when there are strict budget constraints. This system has been designed specifically for under wood flooring & consists of a thin cable evenly spaced, contained within a 500mm wide foil matting which allows for quick & easy installation. Please choose an electric underfloor heating system that will cover 90% of your floor area. It is best to order slightly less than you need than have too much as the cables CAN NOT be cut or shortened. This kit comes with a 15 year manufacturer warranty.
