Recommended Applications

Cool Cover™ Reinforced TPO Perimeter Strip is designed for non-penetrating securement of the TPO membrane in ballasted, fully adhered, and mechanically fastened roof systems.

Application Methods
  1. Place the Cool Cover™ Reinforced TPO Perimeter Strip horizontally or vertically in the angle change with the pre-applied tape in the horizontal position and facing up.
  2. Installll seam fastening plates and screws, a maximum of 12” (30.48cm) o.c. Use fastener placement markings on TPO sheet as a guide.
  3. Clean portion of TPO field membrane that will be adhered over Cool Cover™ Reinforced TPO Perimeter Strip.
  4. Apply Millennium Single-Ply Primer or Millennium Primer 240 on portion of TPO field membrane that will be adhered to the Perimeter Strip utilizing the supplied pad. Scrub the membrane in a circular motion.
  5. Allow the primer to dry to the touch (no material transfer), typically less than 20 minutes. Dry time will vary depending on ambient temperature and humidity.
  6. Once the primer is dry immediately installll TPO membrane. Remove release liner and set the TPO membrane onto the Cool Cover™ Reinforced TPO Perimeter Strip and press in by hand.
  7. Once the release liner has been removed, reinforce the field membrane to tape bond by rolling with a 2”(5.08cm) wide silicone roller. NOTE: The adhesive tape will continue to build bond strength to the primed TPO for several hours after installation.
  8. Gently pull the TPO field membrane back to the adhered tape line to expose the un-adhered portion of the TPO field membrane. Install TPO membrane manufacturer’s recommended bonding adhesive to the parapet wall, the exposed mechanically fastened portion of the Cool Cover™ Reinforced TPO Perimeter Strip, and to the underside of the field membrane.
  9. Once adhesive has dried roll the field membrane in place for 100% adhesion through the elevation transition.

Surface Preparation

All work surfaces should be clean, dry, and free of dirt, dust, debris, oils, un-adhered coatings, deteriorated membrane and other contaminants that may result in a surface that is not sound or is uneven.

  • Not to be used without mechanical fasteners.
  • Not for use with PVC membrane.
  • Talc dust, oil, ice, snow or wet conditions inhibit good adhesion to the pressure sensitive tape. Clean and dry surfaces are necessary for proper Installation of this product.
