Reduce procurement uncertainty
Review the Project Before Releasing It to Production
For imported custom windows and doors, the key commercial risk is rarely the frame alone. It is the gap between drawings, selected configuration, documented performance, site openings and the final production order.
- Review opening schedules, elevations and key dimensions
- Match operating types to access, ventilation and spatial needs
- Confirm finish, glazing, hardware and accessory selections
- Align available documentation with the selected configuration
- Prepare order, labelling and packing information for delivery

Start with Documented Reference Data—Then Confirm the Exact Build-Up
Performance values can change with size, glass, hardware, opening type and test method. DERCHI reviews the selected system and configuration before it is treated as project data.

Technical documentation
Confirm Certificate Scope for the Selected System
The DERCHI catalogue displays CE certification and CE test-report documentation, ISO 9001 quality-management certification and additional international programmes. For a German project, the project team should verify which documents apply to the exact product, configuration and intended use.

Factory export to Germany
Plan More Than the Product
An international package should account for how units are approved, identified, protected and handed over—not only how they look in the elevation.
- Agree Incoterms, destination and responsible parties
- Coordinate production and delivery milestones with the programme
- Confirm protective packing for unit size and transport route
- Prepare product identification against the approved schedule
- Review installation information and site responsibilities
Selected international projects
Aluminium Windows and Doors Across Different Building Contexts
Use completed-project imagery to discuss proportions, opening formats and façade relationships. Project-specific details should be confirmed separately.
Multi-unit residential
Repeated openings across façades
Consistency in schedule references, finishes and opening types becomes critical when multiple unit layouts share one package.
Urban apartment
Frame rhythm and material contrast
Profile colour, mullion positions and visible sightlines contribute directly to the architectural reading of the elevation.
Residential development
Coordinated exterior openings
A shared finish and design language can connect windows, entrance doors, wide openings and garage access.

Procurement questions
FAQs About Custom Aluminium Windows and Doors for Germany
Yes. Send elevations, opening schedules, dimensions, quantities and performance priorities for review. The project team can then discuss suitable product families, configurations and the information needed before quotation or production.
Include opening sizes, product types, handing, quantities, finish, glazing intent, hardware requirements, performance targets, destination, programme and any available drawings. Clear inputs allow a more useful technical and commercial review.
Yes. DERCHI lists inward-opening tilt-and-turn systems among its aluminium window options. The appropriate series depends on opening size, glass build-up, design preferences and required documentation.
The DERCHI catalogue displays CE certification and CE test-report documentation. Because scope can differ by product and configuration, request the documents relevant to the exact system and intended use instead of assuming one document covers every product.
Customisation is available within the engineering and production limits of the selected system. Dimensions, finish, glazing and hardware should be confirmed together because one choice can affect the others.
The 2026 catalogue describes a 100% full-inspection process before shipment. For your order, confirm the agreed inspection scope, approval records, packaging method and any project-specific verification requirements.
Export and delivery requirements can be discussed for the project. Confirm the destination, Incoterms, schedule, access constraints and division of responsibility so the proposed route matches the commercial agreement.
