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

The best energy performance of any window type: no opening gaps. 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 Nelson
In Nelson, midday sun in late December sits around 13° high, with roughly 7 h 24 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
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.
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.
