White uPVC windows in Morden
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.
uPVC frames need washing a few times a year with warm soapy water and a drop of light oil on hinges and locking points. Drainage slots along the bottom of the outer frame let rainwater escape, so keep them clear of dirt and leaves to stop water collecting in the cill.
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.
uPVC window frames are made from extruded profiles with several internal chambers that trap air and slow heat loss. Larger frames, and those on exposed elevations, are usually reinforced with steel or aluminium inside the profile so they stay straight and the locks keep engaging properly over the years.

- Coast
- Morden is well inland, around 40 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Morden the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. uPVC frames are bulkier than aluminium, so they take a little more glass area from small windows. On south and west elevations, solar-control or neutral low-E glass limits overheating, while north-facing rooms benefit from high light-transmission glass and warm-edge spacers that reduce condensation.
- Access and setting
- 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.
- Rules in England
- 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.

Approved Document Q applies to new homes in England, where doors and windows are expected to meet PAS 24 or an equivalent standard. It does not apply to replacements in existing homes, but PAS 24 products are still a sensible choice.
Options to choose between
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.
Obscure and acoustic glass
Patterned or satin glass for bathrooms and street-facing rooms, and laminated acoustic glass to reduce traffic noise.
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.
uPVC Windows in Morden: questions
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.
Do I need building regulations approval for replacement uPVC windows?
Yes. In England, replacement windows are controlled fittings, so the work must meet building regulations. An installer registered with a competent person scheme such as FENSA or Certass can self-certify the work and you receive a certificate; otherwise approval comes from building control. Wales, Scotland and Northern Ireland run their own systems, and we explain which route applies before work starts.
Are uPVC windows secure?
Modern uPVC windows can be very secure when they have multi-point locks, internal glazing beads, key-locking handles and laminated glass where needed. PAS 24 is the security standard expected for easily accessible windows in new homes in England. Ask for ground-floor windows tested to it, and avoid frames where the glass is beaded from outside.
Will fitting new windows damage my plaster or decor?
Some disturbance is normal, but it is usually limited to the edges of each opening. The glazier cuts out the old frame, fits the new one and finishes the inside with trims, sealant or filler. Older frames set deep into plaster may need some plaster repair, and we flag that at survey so it is covered in the quote.
