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 Dorchester

By midsummer Dorchester has about 16 h 30 min of daylight, but in December only around 7 h 58 min, with the noon sun at about 16°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for fixed and picture windows in England

The rules for replacement windows in England are set by Approved Document L (2021 edition, with 2023 amendments): 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.

Questions from Dorchester

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.

How heavy is a large triple glazed pane?

Roughly 30 kg per square metre with 4 mm glass, more with thicker or laminated panes. A 3 m by 2 m unit can weigh around 180 kg.

How long does it take to get triple glazed fixed and picture windows fitted in Dorchester?

After the survey, typical manufacture time is 4 to 8 weeks, and most homes are fitted in 1 to 4 days.

Do I need permission for triple glazed fixed and picture windows in Dorchester?

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.
