Sliding sash windows in Chipping Norton
The highest town in Oxfordshire, built in stone, and exposed to whatever the weather is doing.
What is built in Chipping Norton
Chipping Norton stands high on the Cotswold edge, with a market square and streets of stone buildings from the seventeenth century onward, a significant listed core, and the former tweed mill on the edge of the town. Around the historic centre there are Victorian stone and brick terraces built with the mill trade, and twentieth century housing on the slopes below, giving a mix of protected frontage and ordinary suburban stock within a short distance.
What that means for your windows
Height and exposure make this a place where the performance figures are worth taking seriously rather than skimming. Wind resistance is Class C4 at 1600 Pa under BS EN 12211, equivalent to gusts of around 115mph, with air permeability Class 4 and water tightness Class 7A. On the stone frontages the survey does the other half of the work, because those openings are individual and a standard size will neither fit nor look right in them.
Two ways to buy in Chipping Norton
Chipping Norton is inside the area our own fitting teams cover, so you can have the whole job done by one company. You can also buy the windows on their own if you have a builder already, which is how most trade customers order.
- Supplied and fitted. We survey your openings before anything is ordered, so the sizes are our responsibility rather than yours. Our own teams fit, take the old windows away and make good the plaster line, and you get a FENSA certificate and an insurance-backed guarantee on completion.
- Supplied only. You send a schedule of sizes, choose the colour, glass, hardware and glazing bar layout, and the windows are delivered kerbside for your own fitter. Popular with builders, developers, self-builders and landlords. On a supply-only order the sizes are yours, because nobody from our side has seen the openings.
1.3 W/m²K as standard, 1.2 with enhanced glazing.

Questions we get asked in Chipping Norton
Are these windows tested, or are those figures typical values?
They are test results, and the Declarations of Performance are downloadable from the homepage without a form. BS EN 14351 covers the windows, BS EN 1279 the sealed units and BS EN 12150 the toughened glass, all dated 28 November 2025, with production certified to ISO 9001 and ISO 45001.
Do stone terraces need anything different from brick ones?
The specification is the same but the measuring is not. Stone openings are deeper, less regular and rarely identical along a terrace, so each is measured individually at survey rather than assumed from the one next door. That is what allows a made to measure frame to fill the opening rather than being packed into it.
