Triple glazed fixed and picture windows in Truro
From the first measure to the handover pack, we handle triple glazed fixed and picture windows for homes in Truro and the rest of Cornwall.

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 Truro
Winter days in Truro are short: about 8 h 02 min of daylight on 21 December, with the sun peaking near 16°. 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 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.
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
The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.
- 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 Truro
Do fixed windows need trickle vents?
The room still needs ventilation. If the fixed window replaces one with vents, ventilation must be provided another way, for example a vented frame or an adjacent opener.
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 Truro?
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.
