Triple glazed timber windows in Calne
If you live in Calne (SN11) and want triple glazed timber windows, start with a free survey: every opening measured, then a written quote that fixes the price.
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 Calne
By midsummer Calne has about 16 h 38 min of daylight, but in December only around 7 h 50 min, with the noon sun at about 15°. 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 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.
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
We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.
