Warranty

DOWNLOAD PDF button-icon

All PermaTherm products are warranted to be free from defects in materials and workmanship for a period of two years from the date of shipment.

A certain amount of “waviness,” or “oil canning,” is inherent in any product made from sheet metal. Installation of large areas of metal panels, or installation of panels to misaligned structures, will cause unnatural stresses, increasing the likelihood of oil canning.

A stucco-like embossed texture in a pre-coated material will reduce the visual effect of oil canning. Oil canning does not affect the structural or thermal integrity of the panel. Minor waviness of the panel does not indicate a defective panel, and is not cause for product refusal.

Minor blisters can sometimes occur when the panel’s exterior face is exposed to the sun. This is caused by the thermal expansion of a blowing agent, which is trapped under the panel face. This is a common phenomenon and is easily repaired, and is not cause for product refusal.

Finished panels free of surface imperfections (dents, mars, scratches, etc.) visible with panel in position of intended use and view under good light from intended installed distance or 8 ft., whichever is greater.

  • Install sealants where indicated to clean dry surfaces only without skips or voids, to ensure weather tightness and integrity of the vapor barrier.
3.3 FIELD QUALITY CONTROL
  • Installer shall make periodic inspections and issue report to architect regarding compliance with manufacturer’s installation recommendations developed for the project.
3.4 ADJUSTING AND CLEANING
  • Repair damage caused during construction.
    • Touch-up mars, scratches, and cut edges to match original finish.
    • If repairs cannot be made to comply with architect’s requirements, remove damage and install new materials.
