The usual choice for period homes and conservation areas. Triple glazed timber windows are made from engineered (laminated) timber, which resists warping, and glazed with a three-pane sealed unit.

Winter light and glass choice in Richmond

On the shortest day, Richmond gets about 7 h 50 min of daylight and the midday sun reaches only about 15° above the horizon. Low winter sun means north-facing rooms here gain little solar heat, which is where triple glazing’s lower heat loss helps most.

Rules for timber 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

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.

  • 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 Richmond

Can I get triple glazed timber sash windows?

Yes, though not every sash design can take a full-thickness triple unit. Where the box and sash sizes limit the unit, we tell you the U-value you will actually get.

How long do timber windows take?

Usually 6 to 10 weeks from survey because each window is made to order and finished in the factory. We never quote less than 5 weeks for timber.

Do you fit triple glazed timber windows in Richmond?

Yes. We arrange surveys and fitting in Richmond and across Greater London. Send your postcode and the windows or doors you want replaced, and we will book a free survey.

Do I need permission for triple glazed timber windows in Richmond?

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.
