Why choose it

The thin-bed mat provides even heat distribution with minimal floor height increase, making it perfect for retrofit projects where raising the floor is not an option. The self-adhesive mesh backing speeds up layout and keeps the cable securely in place during installation. With a fully shielded twin conductor design, it ensures safe and reliable operation. The IPX7 rating means it is safe for use in wet areas like showers when installed according to regulations.

Ideal use cases

• Bathrooms and shower rooms
• Kitchens and utility rooms
• Hallways and living areas with tile or stone flooring
• Renovation projects with limited floor buildup
• New constructions where underfloor heating is planned

Good to know

Installation must be carried out by a qualified electrician in accordance with local regulations. The mat is designed for embedding in thin-bed adhesive; the mesh can be cut to fit around obstacles, but the heating cable itself must never be cut. A compatible thermostat (not included) is required to control the system. For best results, follow the adhesive manufacturer's instructions and ensure proper insulation beneath the mat to maximize efficiency.
