Triple glazed uPVC windows in Windsor
If you live in Windsor (SL4) and want triple glazed uPVC windows, start with a free survey: every opening measured, then a written quote that fixes the price.
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 Windsor
Winter days in Windsor are short: about 7 h 50 min of daylight on 21 December, with the sun peaking near 15°. 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
In England, replacement windows must meet 1.4 W/m²K, or a Window Energy Rating of band B or better. 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
After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.
