Triple glazed timber windows in Powys
Homes across Powys, including Newtown, Brecon and Ystradgynlais, can have triple glazed timber windows measured, made to order and fitted.

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.

Rules in Wales
Wales 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. As in England, replacement windows are a controlled fitting: a competent person scheme installer self-certifies the work, or building control approves it.
Before ordering: Householder permitted development rules do not cover flats, and councils can remove rights with Article 4 directions. Listed buildings need listed building consent. Check with your council before changing the style or material.
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.
- 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
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.
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 timber windows need planning permission?
Replacing like-for-like windows on a house is normally permitted development, but conservation areas, Article 4 directions and listed buildings have their own rules. See our planning guide.
Do you cover all of Powys?
We arrange surveys and fitting across Powys.
Do I need permission for triple glazed timber windows in Wales?
In Wales, householder rules do not cover flats, councils can use Article 4 directions, and listed buildings need consent.
