Note: Full payment is due upon order. The grant refund and tax deduction are applied progressively over a 12-month period.

To receive a deduction, an energy certificate before and after the work is required.

1 Production times may be increased under certain circumstances (e.g., special design, company holiday periods, etc.). For technical reasons, we cannot account for these extensions when calculating production times. Due to external circumstances in the procurement of raw materials such as steel, PVC, and wood, the production time of your order may be increased. Please keep this in mind. This does not give you the right to demand changes in contractual prices or the possibility of terminating the sales contract.
