Triple glazed fixed and picture windows in Thamesmead
Triple glazed fixed and picture windows for homes in Thamesmead: measured on a free survey, made to order and fitted by installation teams working for us across Greater London.

Large fixed panes in triple glazing, with the lift planned. A fixed or picture window does not open; it is one large pane in a slim frame, used to frame a view or bring in light.
Winter light and glass choice in Thamesmead
In Thamesmead, midday sun in late December sits around 15° high, with roughly 7 h 50 min of daylight. For windows facing north or shaded by neighbours, cutting heat loss matters more than solar gain; on open south-facing glass, ask about a higher solar-gain unit.

Rules for fixed and picture 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
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.
- 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 Thamesmead
Is a picture window worth triple glazing?
Big panes lose a lot of heat and can feel cold to sit near. Triple glazing keeps the inner pane warmer, which makes the space by the window more comfortable.
Can a fixed window be the escape window?
No. An escape window must open. We keep or add an opening window where one is needed.
Do I need permission for triple glazed fixed and picture windows in Thamesmead?
In England, like-for-like replacements on a house are normally permitted development; flats need permission if the change alters their appearance, Article 4 areas may need permission, and listed buildings need listed building consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
