Installation Guide
To select the proper size heating mat(s) for your application, measure the area to be heated and determine the heating
mat widths and lengths to fit the clear inside dimensions (wall to wall, etc). It is important to allow up to 5” of clearance
around the perimeter of the room and from any baseboard heating or permanent fixtures to allow the mats to fit without
touching adjacent vertical surfaces or overlapping. Accurate dimensions are required for the proper size selection.
For installations over wooden subfloors, check floor thickness and
for any deflection. Do not install QuietWarmth Peel and Stick direct-
ly over the top of OSB subfloors. At least 1/4” thick cement backer
board should be used over wooden subfloor.
Sketch the System Layout
A sketch of the area to be warmed, including the mat locations and
associated wiring, is recommended to make installation and order-
ing as smooth as possible. See the example sketch below.
Multiple Unit Installations
Installations with multiple heating mats will require a junction box to gang the connections together. If a junction
box is required, it should be located directly beneath the thermostat, 12” to 18” above the floor. The total number
of mats used in a single circuit is limited to 15 amps
When specifying multiple width heating mats for the same area, make sure that the total power required does not
exceed the total power of a single circuit. Add additional 20 amp circuits as required for proper electrical supply
to the installation.

NOTE:
The heating mats can only be cut
to fit length. Do not cut or notch
to fit around any obstructions or
penetrations such as door openings
or floor registers.
