Why Helps

ProMelt Mats install faster and easier than any snow melting system in 3 easy steps once you have read all instructions, planned the electrical details, designed a layout and prepared your jobsite:

  1. Roll out the mats onto prepared base surface or wire mesh/rebar
  2. Make turns by cutting tape and fitting mat to any shape area and around obstacles or up steps
  3. Secure to base or mesh using mat tape, nails or zip ties

The ProMelt radiant heating mats are built tough for Permanent installation within virtually any surface to provide efficient melting of snow and ice automatically. They must be completely embedded and at least 1.25 inches below the top of the new layer.

  • New Concrete Surfaces install in top 2 inches secured to rebar or wire mesh on supports/chairs
  • New Asphalt on top of base layer. ProMelt's polyurethane outer insulation layer withstands 300 Degrees F
  • Pavers or brick set in compacted sand beds or in mortar
  • Stone or tile set in thickset mortar. Building Code requires all outdoor systems to be 1.25 inches below the top of the new surface
  • Not for use in gravel or dirt - must be embedded as described above
