This improved design delivers dramatically better protection against air infiltration, wind, moisture intrusion, and temperature loss compared to older OEM seals.

The Flex‑Leg profile is compatible with a wide range of window “profiles” built from 1977 through 2010, making it one of the most versatile and effective replacement sash seals available.

Why Replace Old Weatherstripping?

Even if older seals “look fine,” they lose flexibility, compression strength, and sealing ability over time. Replacing them restores:

  • Proper sash compression

  • Reduced drafts

  • Better energy efficiency

  • Improved comfort

  • Enhanced window performance
