Built around the buying decision

One project can involve hundreds of details

The difficult part is rarely finding a window shape. It is coordinating the product, performance, documentation, finish, hardware, quantities and logistics without losing control of the project brief.

Unclear system selection

Match frame depth, drainage, operation, glazing and hardware to the opening and environment.

Documentation gaps

Connect the selected series with drawings, configuration details, test information and destination requirements.

Multi-product coordination

Coordinate casement windows, fixed glazing, sliding, folding and swing systems under one finish and schedule.

Quotation uncertainty

A useful quotation depends on dimensions, configurations, quantities, glass, hardware, destination and scope.

Aluminum window and door systems

A coordinated range for different openings

Start with the operation your project needs, then confirm the series, configuration and performance documentation. Aluminum casement windows are the featured window category, supported by sliding, picture, folding and swing systems.

Casement configurations can be reviewed around opening direction, frame depth, glazing, sealing, hardware and the applicable project documentation.

Featured category

Custom aluminum casement windows, specified by series

Casement windows combine controlled ventilation with a compression-sealed operation. DERCHI's catalogue includes outward-opening and awning configurations across multiple frame depths. The correct series depends on the opening, glazing and performance brief.

  • Thermal-break configurations

    Selected systems use insulated aluminum profiles and series-specific frame widths.

  • Glazing built around the system

    The catalogue lists double-tempered, argon-filled insulating glass configurations for featured series.

  • Sealing and locking details

    EPDM sealing and multi-point locking configurations vary by model and should be confirmed before specification.

Representative system data

Compare catalog-reported specifications by series

These values come from the supplied DERCHI product catalogue. They are included to support early comparison—not to imply that one result applies to every size, glass build-up, configuration or destination.

Specification note: Confirm the selected model, dimensions, configuration, glazing and matching test documentation with the project team before design approval or purchase.

Customization and OEM support

Configure the system around the project—not the other way around

Share the opening schedule, drawings or early requirements. The review can then connect product type, size, operation, finish, glazing, hardware and packaging with the intended use and destination.

Dimensions and configurations

Review opening sizes, panel divisions, handing, tracks, fixed/operable combinations and project tolerances.

Glass and performance targets

Align glass build-ups and the selected series with thermal, solar, acoustic, wind, air and water requirements.

Finish and hardware

Coordinate frame color, surface finish, handles, hinges, locks, rollers and other system-dependent hardware.

Labeling, packaging and logistics

Confirm project references, package requirements, shipping destination and the handoff information needed by the buyer.

Documentation by product and market

Request the document that matches the selected system

The official catalogue presents authorization certificates, conformity documents or test reports referencing the following programs and standards. Their presence in the catalogue does not mean every document applies to every product or destination.

  • NFRC product authorizations
  • AS 2047 documentation
  • CSA documentation
  • CE conformity and test reports
  • ISO 9001 quality management
  • ENERGY STAR Canada document

Project photographs help buyers evaluate scale, sightlines, color and opening configurations. Use them as visual references, then confirm the product series and requirements for your own project.

From inquiry to delivery

A clear path from project brief to order support

The exact workflow varies by order, but a structured review reduces assumptions before drawings, configuration and production are confirmed.

  1. Send inquiry

    Share product types, quantities, dimensions or drawings, destination and target timing.

  2. Confirm requirements

    Review opening operation, series, glazing, finish, hardware and performance requirements.

  3. Receive quote and specification

    Align the quotation and technical scope before the order and production information are approved.

  4. Production and inspection

    Manufacture against the confirmed scope and complete the agreed quality-control checks.

  5. Delivery and support

    Coordinate shipment information, documentation and applicable installation or after-sales guidance.
