-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.
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
