INNOVATIVE SOLUTIONS FOR CERAMIC AND STONE TILE

ELECTRIC FLOOR WARMING SYSTEM WITH INTEGRATED UNCOUPLING TECHNOLOGY

Application and Function

6.4 Schluter

-DITRA-HEAT and DITRA-

HEAT-DUO integrate customizable,

comfortable electric floor warming with the

functions of DITRA: uncoupling, waterproofing,

vapor management and support to ensure a

long lasting installation. DITRA-HEAT-DUO

features an integrated thermal break to reduce

impact sound transmission through floor-ceiling

assemblies, reduce heat loss to the substrate,

and improve floor warming response time.

Floor Warming

DITRA-HEAT and DITRA-HEAT-DUO combine

the flexibility of loose heating cables with the

ease of installation of mat systems. Cables

can be placed wherever heat is desired,

without creating height differences in the floor.

Self-leveling compounds are not required to

encapsulate the cables, significantly reducing

installation time and effort.

Sound Control

Controlling impact sound transmission

through floor-ceiling assemblies in multi-story

construction can present challenges, particularly

when ceramic and stone tiles are used. Sound

control materials tend to be compressible and

not all provide adequate support for tile covering

in thin-set applications. DITRA-HEAT-DUO

reduces sound transmission, while supporting

the covering to ensure a lasting installation.

Uncoupling

Tile has been successfully installed for thousands

of years by incorporating an uncoupling layer, or

forgiving shear interface, within the tile assembly.

DITRA-HEAT and DITRA-HEAT-DUO provide

uncoupling through their geometric configuration,

which allows for in-plane movement that

effectively neutralizes the differential movement

stresses between the substrate and the tile,

thus eliminating the major cause of cracking and

delaminating of the tiled surface.

Schluter

-DITRA-HEAT

Waterproofing

DITRA-HEAT and DITRA-HEAT-DUO provide

reliable waterproofing. Their polypropylene

composition protects the substrate from

moisture penetration, which is particularly

important in today’s building environment where

most substrates are moisture-sensitive.

Vapor Management

The free space on the underside of

DITRA-HEAT and DITRA-HEAT-DUO provide a

route for excess moisture and vapor to escape

from the substrate that could otherwise cause

damage to the tile covering above. Thus, DITRA-

HEAT and DITRA-HEAT-DUO effectively manage

moisture beneath the tile covering.

Support/load distribution

When placed on a solid foundation, columns

or pillars can support tremendous loads. The

same physical principle applies to DITRA-

HEAT and DITRA-HEAT-DUO installations.

Column-like mortar structures are formed

in and between the studs on the surface

of the matting. Loads are transferred from

the tile covering through these column-like

mortar structures to the substrate. Since

DITRA-HEAT and DITRA-HEAT-DUO are virtually

incompressible within the tile assembly, the

advantages of uncoupling are achieved without

sacrificing point load distribution capabilities.

S c h l u t e r ®- D I T R A - H E A T Material Properties and Areas of Application DITRA-HEAT is a polypropylene membrane with a cut-back stud structure and an anchoring fleece laminated to the underside. The thickness of the mat, including the stud structure is 1/4" (5.5 mm). DITRA-HEAT-DUO is a polypropylene membrane with a cut-back stud structure and a thermal break anchoring fleece laminated to the underside.

S c h l u t e r ®- D I T R A - H E A T Note: Type, thickness, and format of the tile or stone surface covering must be suitable for the intended application. Minimum tile format is 2" x 2" (5 cm x 5 cm). Due to airspace within the assembly, tile or stone coverings installed over DITRA-HEATDUO membranes may have a hollow sound when they are walked upon with hard shoes or tapped with a hard object.

S c h l u t e r ®- D I T R A - H E A T Testing and Certifications Uncoupling Membrane The method used to establish the overall performance of a tile assembly under loading is the ASTM C627 “Standard Test Method for Evaluating Ceramic Floor Tile Installation Systems Using the Robinson Type Floor Tester.” The assembly is tested in cycles using a loaded, revolving carriage. Load, wheel hardness, and number of revolutions vary with each cycle. Once a specified level of damage is exceeded, the test is stopped.

S c h l u t e r ®- D I T R A - H E A T IIC Impact Insulation Class (IIC) is a rating that characterizes the levels of impact noise transmitted through different floor-ceiling assemblies. It can be used by architects, builders, and specification and code authorities for acoustical design purposes in building constructions. The rating increases as the impact sound attenuation of the floor-ceiling assembly increases. IIC is determined according to ASTM E492 and ASTM E989.
