Classic Style Meets Modern Performance

Coastal Single and Double-Hung windows blend classic style with modern performance, exceeding industry standards for strength and reliability with timeless appeal. Single-hung windows have bottom sashes that are operable while the tops are fixed in place. Double-hung windows have two operable sashes. The design of these windows means less opportunity for air infiltration and better energy efficiency.

Features of Our 500 Series High-Performance Single & Double-Hung Windows:

Ideal for commercial and residential applications, larger window units, high wind-loads, and structures over two stories.

  • 5 1/16″ frame depth eliminates the need for a drywall return on standard double-wall construction
  • Solid vinyl frame, thermal-welded for strength and sealed to provide a lifetime of attractive, low-maintenance beauty and performance
  • Superior stainless steel strap balance and fasteners to resist corrosion and provide smooth, reliable operation
  • Exclusive heavy-duty frame design “captures” the sash for exceptional structural integrity against high wind loads and water infiltration
  • Exclusive non-metallic, sill-overlap handle engineered for security and performance
  • All sashes internally reinforced for superior strength
  • Durable die cast cam locks provide a high level of security
  • Tilt-in movable sash for easy cleaning
  • Sloped sill for positive water drainage
  • Triple-seal weatherstripping provides superior protection against air and water infiltration
  • Superior wet-glazed system and a co-extruded flexible seal on the exterior of the sash prevent leaks and greatly enhance structural integrity
  • Ventilating night latch hardware allows the window to be secured in a partially open position
  • Exterior flush mounted screen available in both full and half screen option
