The innermost part of the Black Aluminum Warmset hank consists of company patented technology plus a polypropylene sheath with an aluminium covering specially designed to heat floors installed by dry-laying.

This underfloor heating product cannot be installed in cement screeds or covered with glue, but gives its best with parquet and laminated wood floors installed by dry-laying or with floating floors, vinyl floors or carpet. These materials can be installed in direct contact with Warmset technology, thus guaranteeing that the system is fully up and running fast and providing uniform heat distribution.
