Warmup DCM-PRO Fleece Backed Decoupling Mat V3

Product Description

The Warmup DCM-PRO Fleece Backed Decoupling Mat V3 is an advanced electric underfloor heating system designed to protect tiled floors while delivering efficient, controllable radiant heat. Using decoupling membrane technology, it separates the subfloor from the floor finish, preventing stress transfer and significantly reducing the risk of cracked tiles or grout.

This makes DCM-PRO one of the most reliable systems for tiled installations, particularly in areas where movement, moisture, or subfloor instability may otherwise cause long-term issues.

The fleece-backed version is designed for installation using traditional adhesives, creating a strong bond with the subfloor while still allowing flexibility during positioning and installation.

For a full system overview and comparisons, see our DCM-PRO Underfloor Heating Guide and Electric Underfloor Heating Systems Collection Guide.
