SunTouch UnderFloor is a safe and efficient radiant electric floor heating system retrofitting an existing cold floor with heat without disturbing the existing floor covering.
UnderFloor is for interior applications only and is intended only for installation under an existing wood subfloor (accessed from underneath via crawl space, basement, or garage ceiling) in residential and light commercial installations.
Insulation is essential after mats are installed into joist spaces.
We recommend SunTouch UnderFloor Mats be installed in all areas where floor warming is desired; the floor is only warm directly over an installed mat.
If UnderFloor is being installed to heat the space, first perform a heat loss calculation to determine the amount of BTUs required to heat the space.
