Platinum Series Insulation®

Two Ways to Improve Your Energy-Efficiency

All Platinum Series Insulation® is made from extruded polystyrene foam. When properly installed over old siding, it provides a continuous layer of thermal and air infiltration protection.

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.

  • Perforations eliminate trapping of water vapor behind the panel
  • Highly resistant to cracking, denting and tearing 
  • Low moisture absorption
  • Flexible -- bends easily around corners without cracking
  • Pre-printed grid lines ensure accurate installation
