Fenêtres Jalmo warrants, for a period of 10 years, under normal conditions of use and installation, sealed glass units against film formation or dust deposits between the panes of glass, caused by seal failure and resulting in a substantially obstructed view (see tolerance grid), excluding spontaneous glass breakage. In such a case, JALMO will provide a new sealed unit and cover the labour costs for the first year only. As of the second year of coverage, JALMO undertakes only to replace defective units. Installation and transportation costs are the responsibility of the customer.
