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.

For claim to be reviewed following must be provided:

• clear photographs showing the level alignment of the frame (using the longest possible spirit level),

photographs of the frame fixings,

• confirmation that fixings of the correct type and length have been used for the specific building structure (e.g. masonry or stone buildings).

• 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.

During the installation of doors and windows, the functionality and level alignment of the products are checked at the time of installation. If, during this inspection, the product opens and closes correctly, the installation is considered to be compliant with the requirements.
Due to the natural behavior of building structures and timber materials, seasonal changes in humidity and temperature may cause the frame, structural elements, or surrounding wall materials to expand or contract. As a result, post-installation adjustment may become necessary, including but not limited to:

• hinge adjustment,

• adjustment of the strike plate (lock keeper),

• inspection and, if necessary, correction of frame fixings.

Such post-installation adjustment is considered normal maintenance and is not covered by the warranty and is not treated as a warranty claim, provided that the product was functioning correctly at the time of installation acceptance.

Products must not remain packed on pallets for more than two (2) months. Extended storage in packed condition may cause material stress or deformation and is therefore excluded from warranty coverage.

 Upon arrival of the goods, the customer must immediately inspect the shipment, including verification that all fittings and accessories are included on the pallet.

 Any missing items must be clearly noted on the transport document (CMR / delivery note) at the time of delivery.

 Complaints submitted later than two (2) months after delivery will not be accepted, as products must be unpacked and inspected within this period.

 Internal duplex movement within the insulated glass unit is a natural physical phenomenon and is not considered a defect and therefore not subject to warranty claims.

The warranty period for fittings is five (5) years from the date of delivery.
The warranty is valid only under the condition that the fittings have been correctly used and maintained on an annual basis, in accordance with the manufacturer’s maintenance instructions.

The warranty covers hidden manufacturing defects only.
Any incorrect handling, improper installation, lack of regular maintenance, or mechanical damage immediately voids the warranty.
