window seal
Pane perimeter barrier
A window seal is the weatherproofing material or gasket that prevents air, water, and drafts from entering around a window frame.
When seals deteriorate, windows become drafty and less energy-efficient: The old window seals need replacing—you can feel cold air coming through.
Sometimes confused with window sill, the horizontal ledge at the bottom of a window.
