All WFS Mat systems utilise our insulated, twisted dual core heating element, protected by an armour braid and our advanced tough heat resistant fluoropolymer outer jacket. All WFS cables have a high IP rating of 67 which is suitable for use in wet areas and in conjunction with wet room systems. The heating element is attached to a 100% fully self-adhesive fibreglass mesh for rapid and superior installation without any need for priming on a clean dust free floor, ensuring zero lift in self-levelling compounds and peace of mind, no messing around with the peeling of double sided tapes. WFS heating mats come with only one power lead wire making it easy to install without raising the floor level. All WFS cables are manufactured in Sweden, world leaders in underfloor heating process and quality. WFS Cable manufacture complies and surpasses all UK and European standards and requirements.
