A way to triple glaze a whole house without the timber or aluminium premium. Triple glazed uPVC windows are plastic-framed windows fitted with a sealed unit of three glass panes and two gas-filled cavities.

Winter light and glass choice in Durham

Winter days in Durham are short: about 7 h 13 min of daylight on 21 December, with the sun peaking near 12°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

Rules for uPVC 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.

Planning: 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

You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.

  • Free survey and a written quote fixed for the specification
  • Glass build-up and whole-window U-value on every quote
  • Written handover pack at the end of the job
  • Guarantees on frames, units and fitting in writing

Questions from Durham

Will triple glazed uPVC windows look bulky?

The frames look much the same as good double glazed uPVC. The glass unit is thicker, but that sits inside the frame, so from outside the difference is hard to spot.

Do I need trickle vents?

In England and Wales, if your old windows had trickle vents, the new ones must have vents at least as big, and if they did not, the room must be no less ventilated than before. Scotland and Northern Ireland also require that replacement windows do not make ventilation worse. We size vents on the survey.

How long does it take to get triple glazed uPVC windows fitted in Durham?

After the survey, typical manufacture time is 4 to 6 weeks, and most homes are fitted in 1 to 4 days.
