When combined with a proper water-resistive barrier, wall sheathing panels and stucco finish system, Stytek’s DripWave system provides a cost-efficient, uncomplicated solution to complex exterior building wall issues.

DripWave Plus insulation panels are fully tested for resistance to water penetration, UV degradation, thermal resistivity and fire performance properties and comply with Type II of ASTM C578, “Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation.” Certified test results are available upon request.

The DripWave Plus insulation system has 4 major components:

  • Water-managed rigid foam board insulation with tongue-and-groove joint design
  • Low “E” metalized radiant barrier
  • Self-adhering board joint tape
  • Galvanized metal weep screed
