If such defects occur, R. Lang will provide a replacement unit under the outlined terms and conditions above. Condensation on windows which may occur as the natural result of humidity within the house or building and interior/exterior temperature differentials does not indicate a defect in the window and is not included in the warranty. Additional information concerning condensation is available upon request. Not Supplied With Window...R. Lang assumes no responsibility, implied or otherwise, with sealed insulating glass units, or any other glass unit, used with any window unless that sealed insulating glass unit is supplied by R.

2. Any damage to the product caused by impact of foreign objects, acts of God, or by fire, explosion or other casualty.
3. Windows that have been painted, varnished or similarly coated over the original vinyl surface by anyone other than R. Lang.
4. On some installations caulking is used to seal the frames or trim package against water or air penetration. Caulking is not considered a part of the window, and, therefore, is not covered under this warranty. Caulking is normally considered a maintenance responsibility of the homeowner.
5. R. Lang reserves the right to discontinue or modify any of its products, including the color thereof, without notice, and shall not be liable as a result of such discontinuance or modification, nor shall R. Lang be liable in the event replacement material may vary in color or gloss in comparison to the original product as a result of normal weathering. If R. Lang replaces any product under this warranty, it may substitute products designated by R. Lang to be of comparable quality or price range in the event the product initially installed has been discontinued or modified.

How To Make A Claim

The property owner must promptly notify in writing the contractor/builder/dealer who installed the window in order to provide an opportunity to investigate the claim and examine the product claimed to be defective. R. Lang and/or its local fabricator who manufactured the window will be notified of the claim by copy of the contractor/builder/dealers report. R. Lang or its local fabricator will then investigate the claim. If a defect covered by this warranty is confirmed, R. Lang shall, within a reasonable amount of time after inspection, either repair or replace the defective window as outlined in the terms and conditions above.

Window Maintenance

The factory recommends the use of warm soapy water to clean all surfaces, including vinyl components. DO NOT USE Petroleum, Aromatic, Aliphatic, Acetone, or Ammonia based cleaners or solvents on any surface of the Tru-Frame® Vinyl Greenhouse Window. The use of these cleaners or solvents on any surface will void the warranty on the window and components. As with any window in a resedential installation, all joints and surfaces should be checked at least once a year for gaps/points where caulking should be added for the best seal or performance. As mentioned above, caulking will shrink and move, is not considered a part of the window, and is not covered in the warranty.
