Features and Benefits

  • Is highly resistant to cracking, denting and tearing
  • Helps prevent warping and delamination
  • Provides a solid, flat surface for new siding installation
  • Does not crumble and clutter the jobsite
  • Cuts cleanly and evenly for tighter installation

Platinum Series Fanfold Re-Siding Underlayment

This extruded polystyrene underlayment provides improved R-value and a solid, level base for new siding. A clear plastic film laminate provides strength at the “cut and fold” hinge so that the panel lays flat against the wall.

  • Low moisture absorption
  • Flexible — bends easily around corners without cracking
  • Pre-printed grid lines ensure accurate installation
  • Available in 1/4” and 3/8” thicknesses
  • Available in 3/8“ thickness with reflective facer to deflect solar energy

Platinum Series Insulation Board with Interlocking Edges

This extruded polystyrene foam insulation board features shiplap edges for a tight fit and improved energy-efficiency – up to 3.8 R-value. The interlocking sheets provide a continuous layer of thermal and air infiltration protection.

  • Reduces energy costs
  • Resists air and moisture
  • Does not hold water
  • Retains R-value long-term
  • Cuts easily and cleanly
  • Doesn’t crumble
