The measured width (W) and height (H) of the opening are not the dimensions directly ordered. Adjustments must be made for the installation gap:
Installation Gap: Space for foam adhesive and leveling. Conventional value is 10mm-20mm per side, depending on wall flatness and profile requirements.
Example: For a 1498mm x 1598mm opening with a 15mm required gap per side, the order size would be 1468mm x 1568mm.
