A natural, traditional look with modern heat-loss figures. 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 Heston

On the shortest day, Heston 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

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

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 Heston

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 I need permission for triple glazed timber windows in Heston?

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.
