WIKĘD KÖMMERLING 76 AD PVC Window System

WIKĘD KÖMMERLING 76 AD is a uPVC window system built around a 76 mm profile with five chambers and two external seals. Those details give a buyer a clear starting point for comparing the profile construction and its glazing allowance. The system is listed for two- or three-pane glazing units from 24 to 50 mm thick. Rather than using the profile label to infer a complete window performance, use these published limits to check whether the proposed unit can accept the specified glass and whether the selected sash layout suits the opening.

The AD configuration has two external seals. This is the specific sealing arrangement documented for this model; the description should not be read as a promise of a particular air, water, or sound result. Those outcomes depend on the finished window and installation. When reviewing a quote, ask which glazing package sits within the stated 24–50 mm range and whether the quoted measurements refer to the complete window or only the profile system. Confirm also the frame dimensions, reinforcement, hardware, color, and opening configuration on the order so the delivered assembly matches the project schedule.

Use the opening plan to decide where the operating sash belongs and how it will clear the interior. A two-pane or three-pane unit may be selected within the stated thickness range, but the final glass make-up should be chosen for the building’s needs and checked against the system limits. For adjoining windows, coordinate mullion positions and sightlines before ordering so the profile depth and sash divisions support the intended elevation. In a replacement, make a careful site measurement and agree on the frame-to-opening detail; in new work, align the window schedule with the rough openings and finish layers. The published profile data are useful as a filter during early comparison: 76 mm depth, five chambers, two external seals, and a defined glazing interval. They do not replace a calculation for the whole window or establish a regulatory class for the finished unit. Before approval, compare the glass thickness and sash design against the same project opening, then check what installation and finishing work the quote includes. If a supplier proposes a different glass package later, confirm again that it fits within the system range and that any quoted performance remains valid for the revised assembly. For a reliable comparison, make sure the competing offers describe the same opening size and glass make-up. A price or profile depth on its own will not show whether the quoted unit uses the same sash divisions. Keep those details with the selected AD model in the approved window schedule.
