WIKĘD KÖMMERLING 76 MD PVC Window System

WIKĘD KÖMMERLING 76 MD is a uPVC window system with a 76 mm profile, six chambers, and three seals including a central seal. It accepts two- or three-pane glazing units 24–50 mm thick. These specific construction details help define the model: the 76 mm depth is shared with the 76 AD system, while this MD version has one additional chamber and a central seal. If a project is comparing both names, check the exact model suffix on the quotation and order; similar profile depth does not make the two builds interchangeable.

The central seal is part of the system’s three-seal arrangement. Treat that as a description of the profile, not as a standalone rating for the completed window. The selected glass, sash dimensions, fittings, and installation affect the final unit. During specification, confirm that the proposed glazing package falls between 24 and 50 mm and that it is appropriate for the opening’s documented needs. Ask the supplier to identify the tested or calculated performance for the exact configuration if the project has a numerical requirement. This preserves the distinction between published profile construction and a result assigned to one finished window.

A 76 mm platform can be useful in comparing frame depth and glass options across a window schedule, but each opening still needs its own layout. Decide whether a sash is fixed or operable, where its handle and movement will sit, and how it relates to adjacent frames. For a multi-window elevation, review sightlines and mullion alignment so the repeated units look deliberate. For a replacement, measure the rough opening and settle the perimeter finishing detail before manufacture. The combination of those project decisions with the confirmed MD profile gives the fabricator a complete basis for preparing the unit. The central seal is the clearest distinguishing detail when a buyer compares this model with another profile of the same depth. Keep that distinction explicit on the window schedule, because the number in the name alone does not identify the sealing layout. Then pair it with the 24–50 mm glazing range to review whether the intended glass package fits. For a repeat order, preserve the exact model suffix and glass description on the specification so a similar-looking alternative is not substituted without review. This is a practical way to retain the selected profile details through design, quotation, and installation. A clear schedule should name the MD version, show the chosen glazing thickness, and identify each fixed or operable section. That gives the manufacturer a consistent basis for a configured-unit calculation and helps prevent the shared 76 mm depth from obscuring the important difference in seal construction.
