GND Warranty Doors

Guaranteed GND
GND has been setting the standard for quality doors for 35 years.

GND is a foundation to which the top Dutch interior and exterior door manufacturers are affiliated. GND has been setting the standard for quality doors and offering clients and buyers security for 35 years. Manufacturers affiliated with GND must meet the requirements as stated in the Statutes of the Foundation.

GND Guarantee
The member manufacturers guarantee the quality and functioning of wooden doors through the GND Guarantee. To benefit from the GND guarantee, each manufacturer has entered into an agreement with GND. The warranty is provided by the door manufacturer in accordance with uniform GND warranty conditions, which are set out in an agreement between GND and the member manufacturer.

What does GND do
The umbrella cooperation works integrally to promote the quality of the doors of GND's member specialized door factories, to promote trust between these door manufacturers and their customers and social issues such as safety and sustainability. For example, a special GND guarantee label has been developed to make the fire, smoke, noise and burglar resistance of a door or door-frame combination easily visible to everyone, and we strive to use FSC/PEFC certified materials.
