    or other non-corrosive materials compatible with aluminum such as zinc-plated steel
    properly treated for corrosion  resistance.
  • All 4 frame corners and meeting rail connections are sealed with Polyseamseal to keep
    the weather out and reduce air infiltration.
  • Sash members are interlocked for additional strength at corners and locking rail.
  • Two positive sash locks reduce air infiltration. (should remain locked when installing)
