LAYING THE INSULATION & THERMOFILM
The Thermal Insulation/Noise Reduction Pads
Use of plain (not foil faced) underlayment padding,
minimum thickness (1/4”) with a minimum thermal
resistance value of 0.97 ft².hr.°F/BTU is recommended
(R=1). Thermosoft offers Cerazorb™ synthetic cork and
Insulayment™ compressed fiber underlayment pads, which
work fine for that purpose. The THERMOFILM™ Film
should be placed on top of the underlayment.
Thoroughly clean the existing floor area removing any
sharp objects.
Lay the underlayment padding on the sub-floor (fig.3).
Note: The moisture barrier may be required to be placed
directly on concrete sub-floors, below the underlayment
padding, to prevent moisture accumulation in the floor.
Always remember to cover the total floor area with
insulation even unheated areas. Tape along the edges
using duct tape. Carefully cut a channel in the insulation at
the position of the sensor conduit channel using a sharp
knife and straight edge. Tape over the sensor or conduit
using duct tape.
The THERMOFILM heating system is available for use
with 120V or 240V supply.
Power output is 11 W/Sq.Ft.
Widths: 1.5ft and 3.0ft overall.
