Bay and bow windows
Windows that step out from the wall to bring in light from three directions and give a room a little more space to breathe.
Windows
The best seat in the house
A bay window is made of three or more frames joined at an angle so that it projects from the face of the building. A bow does the same with a gentler curve, usually four to six equal panes. Both catch light from the sides as well as the front, and both make a room feel larger than its floor area suggests.
Bays are also among the most demanding windows to replace, because on many houses they help to carry the structure above. That is why we survey, manufacture and fit them as one job, with the right structural poles and a proper understanding of what the window is holding up.
Light from three sides
Side panes catch morning and evening sun that a flat window never sees.
Properly supported
Load-bearing bay poles and jacks are specified at survey for the structure above.
Warm where it matters
A-rated glazing and insulated cill boards deal with a traditional cold spot.
Angles made to fit
Frames are manufactured to the angles of your existing bay, not forced into them.
Bay or bow?
A bay has a flat centre section with angled returns, typically at 90, 135 or 150 degrees. It is the familiar shape of Victorian terraces and 1930s semis, and usually comes with a deep internal cill or a window seat.
A bow is a shallow arc of equal-width panes. It projects less than a bay and gives a softer, more elegant line, which suits cottages and wider openings. If you are replacing an existing window we will normally match what is there; if you are forming a new projection we will advise on what the wall, and the planners, will allow.
Replacing a bay the right way
Older bays were often built with timber or masonry corner posts doing structural work. When the old frames come out the load has to go somewhere, so we fit steel-reinforced bay poles sized for the job and support the structure while the work is done.
We also take care of the parts around the glass: new internal cill boards, insulated and sealed junctions, and tidy finishing inside and out so the bay looks as if it has always been there.

Questions
Good things to ask
Straight answers to the questions we hear most about this product.
Does a bay window need structural support?
Frequently, yes. Many bays support the wall, floor or roof above. We assess this at survey and fit load-bearing bay poles where needed. It is the main reason a bay should be replaced by an experienced installer.
Can you replace a flat window with a bay?
It can be done, but a new projection needs a base and a roof or canopy and may need planning permission, particularly at the front of a house. We will tell you honestly whether it is practical for your property.
Will a new bay be warmer?
Yes. Old bays lose heat through thin glass, uninsulated cills and gaps at the corner posts. New A-rated frames with sealed, insulated junctions make a noticeable difference to comfort in the room.
