Bow WindowBay and Bow Window Glazing

Choose from a range of glazing styles to finish your new bay window.

All our windows are fitted with the super efficient Planitherm glass, but in addition you can opt for:

  • double or triple glazing,
  • Georgian bars*
  • Astragal bars*
  • Leaded effect

Bay WindowYou can also choose the handles you’d prefer to suit your window frame choice.

 * Astragal bars are planted on to the window glazing internally and externally giving the effect of traditional period features. Astragal bars are applied to one single piece of glazing, but give the effect of multiple panes of glass.

Georgian bars are set inside the sealed unit, which means that they are sandwiched in between layers of glazing. Rather than being added to the glazing, they are sealed within the unit interior.
