Kasson & Keller Windows

Vinyl  Door Warranty

The rigid extrusions shall not, under normal atmospheric conditions, chip, crack, blister or peel for a period of fifteen years from date of purchase. This warranty does not cover the possible fading of the PVC extrusions.
Kasson & Keller Window Systems will warrant the insulating glass to be free from material obstruction which restricts vision resulting from film formation, moisture or dust collection between the interior glass surfaces for a period of ten years from date of purchase.
Parts such as rollers, handles, locks and latches shall be free of defects for a period of five years from date of purchase.
Condensation (or sweating) on either the glass or frame section of window units is determined by the difference in temperature between the exterior and interior sections of the unit along with the level of humidity present in a house. Due to the variability of temperature/humidity conditions from house to house, Kas-Kel Window Systems is unable to give a consumer warranty regarding condensation.
