Characteristics & Benefits

The Melodium hybrid windows come with the following features:

  • 5’’, 5 5/16” and 6 9/16” rigid multi-chamber PVC fusion welded frames with extruded aluminum exterior
  • The welded PVC sash with aluminum extrusion is located well inside the warm portion of the wall
  • Sash opens 90° for easy cleaning from inside
  • Structural assembly and integrated brickmould improve water tightness
  • Warm-edge glazing unit
  • Multipoint locking mechanism
  • Standard overlap screen

Optional features

  • High-performance glass
  • Virtually unlimited grille and SDL patterns
  • Various brickmould options
  • Selection of jamb extensions
  • Wide array of colours (interior and exterior)

Multipoint locking hardware provides desirable aesthetics and a more consistent seal with the frame. Alweather’s locking systems pass the toughest forced-entry tests, giving you increased security and peace of mind. Options are available to add laminated glass. In addition, for extreme situations, stainless steel reinforcement can be added to sash profiles. We can recommend a solution to any challenging environment.
