Round Tops & Custom Shapes


Make an ordinary room extraordinary. Adding a quarter-round, half-round or elliptical window above any standard Integrity unit immediately adds light and drama to a space. To top it all off, the rugged Ultrex exterior as well as an optional integral nailing fin actually adds to our round tops stability and strength.


  • Low-maintenance Ultrex exterior with rich pine interior
  • Standard Low E II insulated glass with Argon gas
  • An integral Ultrex nailing fin makes round top windows extremely weather-tight
  • Add Simulated Divided Lites, Grilles-between-the-Glass or Wood Interior Grilles for a classic touch
  • A choice of exterior colors, interior colors, hardware finishes, divided lites and standard sizes
