Triple glazed bay and bow windows in Thame
Triple glazed bay and bow windows for homes in Thame: measured on a free survey, made to order and fitted by installation teams working for us across Oxfordshire.
Three- and five-light bays, structure checked and supported. A bay window projects out from the wall in angled sections; a bow window curves in more, shallower sections.
Winter light and glass choice in Thame
By midsummer Thame has about 16 h 41 min of daylight, but in December only around 7 h 47 min, with the noon sun at about 15°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for bay and bow windows in England
England requires replacement windows to achieve 1.4 W/m²K, or a Window Energy Rating of band B or better, which good triple glazing passes comfortably. Replacement windows are a controlled fitting. A competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council within 30 days; otherwise a building control body approves it.
Before ordering: Replacing windows on a house is normally permitted development if the new ones look similar. New upper-floor windows in a side wall must be obscure glazed and fixed, or open only above 1.7 m. Flats and maisonettes have no householder permitted development rights, so a change that alters their appearance needs planning permission. An Article 4 direction in a conservation area may mean permission is needed, and listed buildings need listed building consent.
How it works
We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions from Thame
Will the bay be warmer?
Yes. Replacing old double or single glazing in a bay with triple glazing cuts heat loss through the glass and makes the glass surface warmer, so the room feels less draughty.
Do bay windows need bay poles?
If the old frames carry load from above, yes. We check on survey and include support in the quote where needed.
