WIKĘD Procural Aluline PE78N Aluminum Window System

WIKĘD Procural Aluline PE78N is an aluminum window profile system with a 78 mm frame depth. The manufacturer publishes a reference-window Uw value of 0.88 W/(m²K) for this system. That figure belongs to a specified reference assembly; it is a comparison point, not a guarantee for every custom window made with PE78N. The selected dimensions, glass, hardware, and construction need to be reviewed together whenever a project has a required thermal target. This keeps the profile’s published reference information useful without assigning it to an uncalculated unit.

The sash depth is 86 mm with a 42 mm thermal break. WIKĘD lists maximum sash dimensions of 1,700 × 2,200 mm or 1,200 × 3,000 mm and a maximum sash weight of 200 kg. These are system limits to check during design coordination, not a promise that every size combination or glass package will work in every opening. Confirm the exact opening direction, sash dimensions, selected infill, and fittings with the fabricator. If a design approaches the listed limits, request confirmation for the specific assembly before fixing the surrounding construction.

PE78N is a window system, so the window schedule should distinguish it from similarly named door or HI variants. Review which parts of the façade are fixed and which should operate, then coordinate the required clear opening with the frame divisions and room use. The manufacturer’s page lists system performance and dimensions, while the actual unit still needs a project-specific configuration. Use the reference thermal value only when its test or reference conditions are relevant to the comparison; for a different size or glazing package, ask for the corresponding calculation. This makes the specification understandable to the designer, buyer, and installer. When the project uses a large sash, verify the stated width-and-height pair and weight together with the selected glass, frame combination, and opening hardware. The published system maximum is not a guarantee for every possible proportion, so have the fabricator check the exact dimensions before the opening is built. The reference Uw also depends on a reference window and glass make-up; ask for the method and unit details if that figure is used in a comparison. Keep the approved drawing and performance information tied to the same PE78N assembly to prevent a later configuration change from being mistaken for the original specification. Document the final glass and sash arrangement together with the reference conditions used for comparison. That makes it clear which published system limits apply and which values belong only to a calculated project unit, especially if the design changes after the initial quote.
