Corner Seal Pad (Left and Right)


Without precision engineering in this critical area, wind pressure can push moisture-laden air through the corner and up the frame, leaking into the home and rotting the frame.


  • Fit securely behind the weatherstrip to help block wind-driven moisture infiltration.
  • Designed to mate with our inswing sills to complement weathersealing performance. (Not required for outswing sills.)
  • Flexible, foam-filled material holds its shape over time, protected by a durable jacket to resist moisture and wear.
