Safety through quality

We are convinced about our products and our services. We want to share this with our customers. We therefore give warranties above and beyond the normal warranties.

Every Internorm product is custom-manufactured according to individual wishes and documented seamlessly via the "identity number".

Furthermore, Internorm issues a commitment that Internorm products can be repeatedly serviced by our experts in such a fashion (original parts not obligatory) as to retain their full function for a period of 30 years. However, this presupposes that the frame construction (frame and sash) is not damaged. The 30-year period starts from the production date. The services required to maintain the functionality, including the necessary materials, labour etc., will be invoiced according to the currently valid rates.
