What Makes uPVC Bay Windows Different from Standard Windows?

Bay windows are a timeless architectural feature that, instead of sitting flat against the exterior wall, projects outward from the main walls of a property, forming a “bay” shape and creating a small internal ledge or extra floor space.

Bay windows never go out of style because of their unique structure, impressive from the outside and spacious from the inside, giving you an extra nook without a full extension.

  • Two Side Windows (angled back)
  • Projecting Frame (extending outwards)

Opening Styles of Bay Windows

You can have your bay windows in the following opening styles, or let us know if there are specific requirements, and we will meet your expectations:

  • Casement: The sash overlaps the frame, forming a lipped edge.
  • Flush Casement: The sash sits completely level with the outer frame.
  • Sliding Sash: The sash slides vertically rather than opening outwards.

FAQ's

Do uPVC bay windows need Planning Permission approval?

You do not require Planning Permission if you are replacing the bay window or installing them on the side or back of the house; however, installing a new bay window at the front of the house will be treated as an extension and will require a permit.

These are the bay window shapes:

  • A window with a flat front pane with the two side sections set at a 45° angle, forming a tapered shape (splayed bay window).
  • A window with a flat front and two sides at 90°, forming a rectangular box (box bay window).
  • A window with a curved bay made up of 4 or 5 equal panes set at gentle angles, forming a smooth arc rather than sharp corners (bow bay window).

If you are looking for affordable, energy-efficient, low-maintenance windows, uPVC bay windows are the best option, fitting any architectural style.

Yes, a damaged or sagging uPVC bay window can often be repaired, depending on whether the issue is with the window components or the underlying structural support.
