About uPVC windows in County Durham
Low-level glass needs safety glazing. In England, Approved Document K treats any glazed panel within 800mm of the floor as a critical location, so a full-height pane, a low picture window or glass beside a door usually needs toughened or laminated glass, permanently marked to show its classification.
Some upstairs windows are escape routes in a fire. In England, the Approved Document B guidance for an escape window is a clear openable area of at least 0.33 m², at least 450mm high and 450mm wide, with the bottom of the opening no more than 1100mm above the floor.
In England, Approved Document L sets the standard for a replacement window in an existing home: a U-value of 1.4 W/m²K or better, or a Window Energy Rating of band B or above. The new window should also be no worse than the one it replaces. The other UK nations set their own figures.
Bay windows need extra care. Some older bays carry load from the wall or roof above, so the glazier checks the support before removal and may fit bay poles or ask for structural advice. Replacing a window in the same opening is different from widening it, which needs a new lintel.

What applies in County Durham
Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.
Listed buildings in England need listed building consent for most changes to historic windows or glass, and conservation areas can restrict changes visible from the street. Speak to the council's conservation officer before ordering.
County Durham has its own coastline, so for homes and businesses near the sea, salt air and wind-driven rain are part of the brief. Near the coast, salt spray and wind-driven rain test seals, drainage and hardware. uPVC itself does not corrode, but stainless or coated locking parts, well-sealed joints around the frame and clear drainage slots matter, and exposed elevations may need frames with higher weather ratings.
Older rural cottages often have irregular openings, thick walls and timber lintels, so every frame is measured individually and the support above each opening is checked. Exposed hillside and open-field sites benefit from reinforced frames and careful sealing against driving rain.

Choosing your uPVC windows
Tilt and turn
Opens inwards from the side for cleaning or escape, or tilts from the top for secure ventilation; practical for flats and upper floors.
uPVC sliding sash
Vertical sliders that mimic traditional box sashes, using spring balances instead of weights, where planning rules allow uPVC.
Woodgrain and colour foils
Grey, black, cream or woodgrain foils on one or both faces, so the frames can match a door or suit an older house.
Double or triple glazing
Low-E double glazing suits most homes; triple glazing adds a third pane for lower heat loss and quieter rooms, but units are heavier.
uPVC Windows in County Durham: questions
How much do uPVC windows cost?
The cost of uPVC windows depends on the size and number of windows, how many sashes open, the frame colour, the glass and the access. White casements with standard double glazing sit at the lower end, while foiled colours, triple glazing and bay windows cost more. See the guide prices for typical ranges; the written quote fixes the price for your specification.
Should I choose double or triple glazing?
Well-specified double glazing with low-E glass and warm-edge spacers can meet the energy standard for replacement windows, and the certified rating confirms it. Triple glazing adds a third pane, which helps on cold, noisy or north-facing elevations, but the units are heavier and need frames designed for them. We can quote both so you can compare.
Can uPVC windows be fitted in a conservation area or listed building?
Sometimes, but consent may be needed first. Listed buildings need listed building consent for significant works, and conservation areas or Article 4 directions often restrict changes to front windows. Woodgrain foils or uPVC sliding sashes can occasionally satisfy a planning officer. Check with your council before ordering; the council can tell you what an application needs, and we can provide product details and specifications to support it.
Do new uPVC windows need trickle vents?
In England, usually yes. Approved Document F expects ventilation after window replacement to be no worse than before, which normally means trickle vents in the new frames. Our glaziers record the existing ventilation at survey and specify vents to suit each room. Rules in the other UK nations differ, so the detail is confirmed for your address.
