The product warranty is valid exclusively for factory-painted elements and presupposes continuous surface treatment and maintenance concerning damages and paint degradation. The product warranty covers either repair or compensation. Discontinued products are replaced by similar ones. The warranty does not cover indirect damages, installation, or related expenses.

• Klar's warranty does not cover indirect damage caused by incorrect installation, lack of lubrication or maintenance.

• The warranty does not cover after-sales services such as adjustment of hinges and frames, varnishing, repair of small cracks in the wood, removal of knots, or repair of blisters or bubbles in the paint.

• The warranty does not cover elements installed in particularly exposed areas with strong climate and environmental influences, such as coastal areas or similar.

Thermal break

A thermal break/explosion is a crack that develops from the edge of the pane. This can occur when there are different temperatures on the glass due to, for example, partial shade, furniture, textiles or heat sources too close to the glass surface. Our warranty does not cover thermal breakage of any kind.

Regulation of atmospheric pressure

Insulating glass contains a certain amount of air and gas that can vary depending on the barometric air pressure. Our standard warranty covers glass panes at 650 metres above sea level. For installation above this altitude, please get in touch with our customer service before ordering

There is no warranty for insufficient waterproofness or water penetration on door elements with a 1-point lock, inward-opening doors or inward-facing double doors.

The visual defect must be assessed from the inside at a distance of at least 2 metres and from the outside at a distance of at least 3 metres, and the assessment must be made in diffuse daylight (e.g. cloudy sky) without direct sunlight or artificial light. Irregularities that are not visible are not considered defects. The warranty does not cover products with visible wood structures due to the natural grain pattern.
