Schluter®-DITRA-HEAT-DUO

Used as an underlayment for tile and stone floors where electric underfloor heating is desired, providing uncoupling, heating cable support, and moisture control in residential and commercial installations.

Schluter®‑DITRA‑HEAT‑DUO is a multifunctional uncoupling membrane designed to serve as both a stable substrate for tile and stone coverings and a dual‑purpose underfloor heating system. It combines the proven uncoupling benefits of a tile membrane with integrated channels for electric heating cables, allowing for efficient and reliable heat distribution beneath finished floors. The design supports moisture management and minimizes stress between the substrate and tile covering, making it suitable for a wide range of residential and commercial applications where heated floors and long‑term performance are desired.

Features and benefits:

• Integrated uncoupling function – Helps separate the tile covering from substrate movement to reduce cracking.
• Built‑in heating channels – Supports placement and secure retention of electric heating cables.
• Enhanced heat distribution – Promotes even warmth across the finished floor surface.
• Moisture management – Assists in controlling water vapor to protect underlying substrates and finishes.
• Thermal efficiency – Designed to work with underfloor heating systems to enhance comfort and energy use.
• Durable surface support – Provides a stable base for ceramic, porcelain, and natural stone floor coverings.
• Ease of installation – Cable channels and membrane integrate with standard thin‑set mortar techniques.
• Versatile application – Suitable for both new construction and renovation projects.
