Floor System Boasts Moisture, Impact Protection


Schluter Systems (Plattsburgh, New York) recently unveiled its DITRA-HEAT-DUO floor system, which the company says is the first system to not only serve as a protective moisture membrane, but also as impact insulation and an electric floor-warming system.

Aimed for use in multi-story, multi-home buildings that come with challenges of concrete construction, the company says that the DUO produces an increase in impact insulation class of 20 to a concrete slab floor, according to ASTM E2179 testing.

The thermal break on the underside of the membrane allows the system to warm a tiled floor up to 70 percent faster over concrete substrates, the company says, attributing this to the uncoupling properties of the membrane.

The company notes that both functions would normally require the installation of multiple layers, and notes that the DUO system is 5/16-inch thick to minimize construction height.

The same uncoupling that aids in the heating element also prevents cracking in the tile by allowing differential movement stresses between the tile and the substrate, the company says.

DUO is composed of polypropylene, effectively protecting the substrate from moisture, according to the company, and the free space on the underside of the system allows for excess vapor to escape.
