When your floor space isn't a neat, regular shape, Cosytoes Loose Cable lets you put underfloor heating exactly where you need it. It's ideal for awkward or irregular areas such as small bathrooms, en suites and oddly shaped rooms, as the cable can be laid around obstacles and into corners that a fixed mat can't reach.
Available in six sizes and just 3mm thick, the cable sits neatly beneath your floor finish without raising levels, and it is compatible with the Cosytoes Cable Carrier Decoupling Mat. Tough PVC outer insulation guards against damage, an aluminium earth wrap adds protection, and the IPX7 rating makes it suitable for wet rooms and bathrooms. A 4m cold lead is included, and every cable comes with a lifetime guarantee.
