Karndean Designflooring is suitable for installing over underfloor heating systems, providing they have been insulated so that the surface temperature does not exceed 27°C (80°F). Designflooring is warmer and softer underfoot than stone and ceramic tiles so is a popular choice for bathrooms, kitchens and sunrooms. Karndean's floors can be laid over underfloor heating systems for extra warmth. When visiting your local retailer, do remember to mention underfloor heating when selecting your floor. If you are arranging for installation of underfloor heating or have an existing system, we recommend making a note of the manufacturer and model. Your Karndean installer will need to ensure that your heating system is compatible with our flooring. We provide full guidance to our flooring installers about sub floor and adhesive preparation when laying Karndean floors over underfloor heating systems.
