Factory-direct project supply Made-to-measure window systems for builders, developers, contractors, distributors and importers—configured around your window schedule, glazing, hardware and performance requirements. Simple, proven operation A single hung window has a fixed upper sash and a lower sash that slides vertically to provide controlled ventilation. Its straightforward mechanism suits repeatable specifications across residential developments, hospitality, modular and light-commercial projects. Fewer moving components support simple operation and repeatable project configurations. The sash moves vertically without projecting into walkways, balconies or interior spaces. Welded uPVC construction supports durable, easy-care window packages. Configure glass, reinforcement, hardware, screens and finishes around the project brief. Built for professional buyers ROPO coordinates the window package around the information each stakeholder needs to approve, purchase, install and reorder with confidence. Window schedule review, technical drawings, production updates, installation details and staged delivery coordination. Standardise profile, colour, glazing and hardware selections across multi-unit residential and commercial developments. Source repeat and bulk orders with controlled configurations, samples, technical information and export packaging. Coordinate sections, glazing, wind pressure, thermal, acoustic and installation requirements before specification.uPVC Single Hung Windows for Commercial Projects

| Operation | Fixed upper sash with a vertically sliding lower sash for ventilation. |
|---|---|
| Frame | Multi-chamber uPVC / PVC-U window profile systems selected to suit the project. |
| Sizes | Made to approved drawings, window schedules or confirmed opening dimensions. |
| Glazing | Single, double or triple glazing; Low-E, argon-filled, toughened, laminated, acoustic, tinted and solar-control options. |
| Reinforcement | Project-specific steel reinforcement based on window dimensions and structural requirements. |
| Hardware | Balance systems, locks, handles, restrictors and corrosion-resistant options subject to specification. |
| Screens | Fixed, sliding or retractable insect-screen options depending on the selected window system. |
| Colours | White, selected solid colours, woodgrain finishes and dual-colour options subject to profile availability. |
| Documentation | Shop drawings, glass build-ups, installation information and applicable performance documents. |
| Packing | Protective export packaging planned around product configuration and shipping method. |
Availability, maximum sizes and performance values depend on the complete window configuration. Final details are confirmed during technical review.
Performance engineering
Glass, profile, reinforcement, seals and hardware work as one system. Performance claims should always be tied to the exact tested or rated configuration.
Review insulated glazing, Low-E coatings, argon filling, frame configuration and solar control against the project energy brief.
For noise-sensitive projects, assess laminated layers, asymmetric glass, air spaces and sealing against the required target.
Window size, mullion design, reinforcement, gaskets and hardware are selected with reference to wind pressure and water resistance.
Specify safety glazing, locking, sash restrictors and insect screens according to building use and the destination requirements.
Project applications
Specify consistent openings across a project, then tailor glazing, hardware and finishes to environmental, architectural and commercial requirements.

Procurement workflow
Early confirmation of sizes, glass, hardware and performance requirements reduces quotation delays, rework and specification gaps.
Share drawings, window schedule, quantities, destination and performance targets.
ROPO checks the brief, identifies missing details and proposes a suitable configuration.
Confirm sizes, profile, glass, colour, hardware, packaging and commercial terms.
Production follows approved documents, with inspection before protective packing.
Receive agreed shipping documents, installation information and after-sales support.
Specify with confidence
Ask for the documents relevant to your selected profile, glass, hardware and destination. Test reports and ratings apply only to the configurations stated in each document.
Request Technical DataBuyer questions
The fastest quotations start with clear project information.
Yes. Sizes are manufactured to approved project dimensions. Feasible sash and frame sizes depend on the profile system, glazing weight, reinforcement, hardware and required wind pressure.
Provide the project location, window schedule or dimensions, quantities, glazing requirements, colours, hardware preferences, performance targets and delivery destination.
A single hung window has a fixed upper sash and an operable lower sash. A double hung window generally allows both sashes to move, which changes operation, hardware and cost.
Options may include single, double or triple glazing, Low-E coatings, argon filling, toughened or laminated glass, acoustic build-ups, tinting and solar control. Availability is confirmed by project.
ROPO can review the target pressure together with window size, mullion layout, reinforcement, glass and hardware. Any published rating must match the exact tested or assessed configuration.
Technical drawings can be prepared for approval before production. Product samples, colour samples or material swatches can be assessed according to the project and shipping requirements.
MOQ and lead time depend on the selected profile, finish, glass, hardware, quantity and delivery programme. Send the project schedule for a confirmed commercial proposal.
Packaging is selected according to product configuration, quantities and transport method. ROPO can review loading and protection requirements as part of the quotation.
