  • Heavy gauge fully extruded handle on bottom sash.
  • Fiberglass mesh half screens standard on all windows.
  • Available in Replacement and New Construction applications.


Full 3¼" Depth Welded Mainframe with beveled colonial exterior features curves that are not only beautiful, but also allow for maximum weld surface resulting in strength and years of long lasting performance.
Optional foam-filled insulated extrusions add energy efficiency in Deluxe version only.
(Insulation type may vary during the manufacturing process)
The sill dam wall is mortised into the jamb on our 505 Series, virtually eliminating any leaks that may occur at corner seals.
Recessed tilt latches on the 505 Series give the window a streamlined appearance as well as holding the sash securely in place. 
The slim sash lock and tamper-proof keeper of the 505 Series not only adds beauty to your window but also ensures smooth operation.
The Bulb Gasket Seal improves thermal performance, lowers drafts, and provides better acoustic insulation.
The 505 Series is a single hung window where only the bottom sash is operational. The only screen option for this window is a stationary half screen.
