A System, Not Just a Frame
Custom work starts with how the building will use each opening
A custom aluminum window or door should be selected as a complete assembly. Opening direction, sash weight, frame depth, glass thickness, drainage, locking, seals and installation interfaces affect how the finished unit performs on site.
DER Building organizes these decisions around your elevation drawings and window-door schedule. This helps keep visually related openings consistent while allowing different rooms, façades and exposure zones to use the configurations they need.
- Match operating styles to ventilation, access, furniture layout and available opening space.
- Coordinate thermal-break frames and glazing where comfort and condensation control matter.
- Review glass safety, hardware load, drainage and installation details before production release.
- Use schedule-based labels and packing marks to support site sorting and installation.
Window and Door System Planning
Select opening types around movement, view, airflow and façade intent
A coordinated package can combine several operating types while maintaining a consistent project language for finish, glazing and hardware.
Sliding Windows & Doors
A practical choice where panels should move parallel to the wall and interior or exterior swing clearance is limited.

Bi-Fold & Folding Doors
Designed for wide openings where the project calls for a larger connection between indoor and outdoor areas.
View bi-fold door systemsWhy Package Coordination Matters
Reduce avoidable changes between design intent and factory output
The most useful customization is not the longest option list. It is a controlled decision process that connects drawings, performance requirements, approved samples and manufacturing information.
01
Consistent façade appearance
Coordinate sightlines, mullion positions, colors and glass appearance across windows and doors that share the same elevation.
02
Clearer hardware schedules
Define handles, hinges, rollers, locks, restrictors and accessory requirements by opening reference instead of relying on generic descriptions.
03
Better installation preparation
Review frame dimensions, fixing zones, sill conditions, drainage paths and perimeter gaps before units arrive at the construction site.
04
More useful quality checks
Inspect units against approved drawings, dimensions, operation, glass, finish and labeling rather than checking appearance alone.
05
Schedule-based packing
Plan protective materials, crate grouping and labels around product size, glass risk, floor, room or elevation references.
06
Fewer quotation assumptions
A complete request helps suppliers compare like-for-like scope and makes exclusions or optional upgrades easier to identify.
Custom Configuration
Define the assembly from frame system to packing mark
Options are reviewed as compatible combinations. Final availability depends on opening size, selected series, glass make-up, hardware capacity and destination requirements.
Opening Size & Shape
Width, height, transoms, sidelights, combined frames and approved project-specific shapes.
Frame System
Project-selected aluminum series, including thermal-break options where required.
Opening Method
Fixed, casement, tilt-turn, sliding, hinged, folding and coordinated combinations.
Glass Make-Up
Tempered, laminated, insulated, Low-E, tinted, obscure or other reviewed configurations.
Surface Finish
Project-confirmed colors, textures and indoor/outdoor finish coordination.
Hardware
Handles, locks, hinges, rollers, friction stays and accessories matched to unit type.
Seals & Screens
Gaskets, brush seals, insect-screen options and other compatible accessories.
Labels & Packing
Opening references, floor or room marks, protection and order-specific export packing.
Specification Framework
Build a quotation that can move into shop drawings without starting over
The table below shows the information commonly reviewed for custom aluminum windows and doors. It is a planning framework, not a substitute for project-specific engineering or local code review.
| Item | Typical Choices | Information to Confirm |
|---|---|---|
| Unit Type | Window, sliding door, hinged door, bi-fold door or combined assembly | Reference number, elevation location, quantity, handing and operation |
| Overall Size | Project-specific width and height within the selected system range | Structural opening, finished opening, tolerances and installation gap |
| Frame | Standard aluminum or thermal-break aluminum configuration | Series, frame depth, sash arrangement, mullions, transoms and sill detail |
| Glazing | Single, insulated, tempered, laminated, Low-E, tinted or obscure glass | Thickness, make-up, safety location, spacer, coating surface and appearance |
| Finish | Powder-coated or other project-reviewed surface options | Color code, gloss, texture, interior/exterior match and sample approval |
| Hardware | Locks, handles, hinges, rollers, restrictors and compatible accessories | Function, finish, keying, opening force, corrosion exposure and load |
| Performance | Air, water, wind, thermal, acoustic or impact scope where applicable | Required standard, rating, test report scope and unit-size limitations |
| Packing | Protective film, corner protection, cartons, crates and loading plan | Shipment method, unloading equipment, site sequence and label format |
For an accurate quotation, send the window-door schedule together with drawings and stated performance requirements.

Frequently Asked Questions
Custom aluminum windows and doors: project questions
What can be customized on aluminum windows and doors?
Typical options include overall size, frame series, opening method, thermal-break configuration, glass make-up, color, hardware, insect screen, drainage details, installation interface and export packing. Available combinations depend on the selected system and project requirements.
Which drawings should I provide for a quotation?
A window and door schedule is the most useful starting point. It should show opening dimensions, quantities, types, handing, glass requirements, color, hardware, location and any required performance or market standard. Plans, elevations and detail drawings help reduce assumptions.
When should a thermal-break aluminum system be considered?
Thermal-break frames are commonly considered where indoor comfort, condensation control or energy performance is important. The final selection should be coordinated with climate, glass configuration, frame size, installation and applicable project requirements.
Can windows and doors be supplied as one coordinated package?
Yes. Coordinating windows, sliding doors, hinged doors and bi-fold doors within one package can simplify color matching, glass selection, hardware schedules, drawing review, labeling and packing.
How is product performance confirmed?
Performance should be confirmed against the selected frame system, glass, dimensions, hardware, installation method and the required test or documentation scope. State wind, water, air, thermal, acoustic or impact requirements during the inquiry stage.
How are custom windows and doors prepared for export?
Packing can be planned around product size, glass risk, unloading method and shipment route. Typical measures may include protective film, corner protection, labels, reinforced cartons or crates and loading plans confirmed for the order.
