Yes, uPVC windows can be installed in older homes, and doing so is actually a popular renovation choice for improving energy efficiency, reducing noise, and lowering maintenance.

Key Considerations:

Customization for Fit and Style:

uPVC windows can be custom-made to fit non-standard or irregular window openings often found in older homes.

They’re available in various styles (sash, casement, tilt-and-turn) and can be finished in wood-effect textures or traditional colours to match the aesthetic of a period property.

Improved Insulation:

Older homes often have single-pane windows. Replacing them with double or triple-glazed uPVC units dramatically improves thermal efficiency.

Preserving Historic Character:

In conservation areas or listed buildings, restrictions may apply. You might need permission to replace traditional timber windows with uPVC. Some manufacturers offer heritage uPVC designs specifically for these cases.

Installation Expertise:

A skilled installer is crucial for older homes, where walls and openings may not be perfectly square or may have settled. Proper sealing and fitting are important to avoid drafts and moisture ingress.

Pros:

Lower maintenance than wood

Resistant to rot and corrosion

Cost-effective compared to timber or aluminium

Long-lasting with proper care

Cons:

Might not be allowed in heritage buildings

If you're considering uPVC for an older property, it's wise to consult a specialist who has experience with retrofitting in historic homes.
