Decoupling Membranes for Underfloor Heating & Tiled Floors
Decoupling membranes play a key role in protecting both tiled floors and underfloor heating systems. They isolate tile layers from the subfloor, preventing cracks and improving overall floor stability.
Types of Decoupling Membranes
For Underfloor Heating: These membranes are designed to pair with electric or water-based systems. They help distribute heat evenly, reduce heat loss, and add a thermal break between the heating cables and tile surface—boosting efficiency and performance.
For Standard Tiled Floors: These membranes offer crack isolation by uncoupling the tile layer from the subfloor. They prevent movement in the substrate from damaging your tiles, extending the life of your flooring.
Material Options
Polyethylene: Lightweight, waterproof, and highly flexible.
Polypropylene: Durable and stable—ideal for high-traffic areas.
Rubber-based: Adds both crack resistance and sound insulation.
Why It Matters
The right decoupling membrane increases floor lifespan, improves heating performance, and protects your investment.
Whether you’re installing tiles with underfloor heating or simply updating a tiled space, a quality membrane is essential for long-term success.
