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 Kettering
Winter days in Kettering are short: about 7 h 40 min of daylight on 21 December, with the sun peaking near 14°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

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
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.
- Free survey and a written quote fixed for the specification
- Glass build-up and whole-window U-value on every quote
- Written handover pack at the end of the job
- Guarantees on frames, units and fitting in writing
Questions from Kettering
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.
Are timber windows warmer than uPVC?
They can be. Timber insulates well, and a deep timber frame with triple glass reaches whole-window U-values around 0.8 to 1.1, similar to good uPVC.
Do you fit triple glazed timber windows in Kettering?
Yes. We arrange surveys and fitting in Kettering and across Northamptonshire. Send your postcode and the windows or doors you want replaced, and we will book a free survey.
How long does it take to get triple glazed timber windows fitted in Kettering?
After the survey, typical manufacture time is 6 to 10 weeks, and most homes are fitted in 1 to 4 days.
