Welcome to SunTouch!
The SunTouch Mat: The heating wire is woven into a spe-
cial orange fiber to make rectangular mats. These mats are
manufactured for 120 VAC and 240 VAC, in 1-, 2-, and 3-ft.
widths. Mats range from 10 sq.ft. to 160 sq.ft., depending on
width, length, and voltage. Mats of different dimensions must
be wired together in parallel (not series) to fill larger areas.
However, they must be the same voltage. For example, to
warm an 80 sq.ft. area, many combinations are possible: two
1’ x 40’ mats; or even a combination of one 2’ x 20’ and one
1’ x 40’. Never combine 120 VAC mats with 240 VAC mats.
SunTouch is a safe and efficient electric floor-warming
product for interior applications. It cannot be used for exterior
snowmelting applications. It is generally intended for installa-
tion below tile, stone, and other masonry flooring materials in
residential and moderate commercial installations. SunTouch
can be used to heat a room, as well as warm the floor, provided
the heat loss of the room falls below the mat’s capabilities.
Please refer to specific design information provided for heat-
ing applications, especially when installing non-masonry
flooring materials. The designer must determine if the output
of the SunTouch is enough heat to match the heat loss of
the structure.
SunTouch is designed to deliver 12 W/sq.ft. The floor tem-
perature attainable is dependent on how well the floor is insu-
lated, the temperature of the floor before start up, and in the
case of uninsulated slab applications, the thermal drain of the
underlying materials. Please refer to your designer if you have
further questions regarding the surface temperature you can
expect from SunTouch in your particular construction.
NOTE: SunTouch has been tested to the American Standard
Test Method ASTM C627, a standard test method
for evaluating ceramic floor tile
installation systems using the
Robinson-Type Floor Tester.
This test was performed by
The Tile Council of America
for installation above a concrete
slab and above a framed floor.
This testing resulted in a rating
of “Moderate Commercial”
for normal (non-vehicular) com-
mercial and light institutional
use. This would include all
(non-vehicular) residential use
as well.
Never install SunTouch directly below vinyl, carpet,
or wood flooring. SunTouch must be embedded in mortar,
per UL requirements. Do not use glues or adhesives.
Non-masonry flooring materials such as carpet, vinyl, or
hardwood can be installed over SunTouch if the mat is
installed in a cement-based or gypsum-based material.
