Aluminium Windows in Thornbury
Contemporary and heritage-style aluminium windows fitted in Thornbury. Slim sightlines, powder-coated finishes. Free survey and insurance-backed guarantee.
Wondering whether aluminium windows are worth the extra cost over uPVC? The honest answer is that it depends what you are after — if slim, contemporary sightlines and a powder-coated finish that holds its colour for years matter to you, aluminium delivers something uPVC simply cannot match in the same frame thickness.
We fit aluminium windows across both, matching frame style and finish to the property rather than offering a single contemporary look for every job.
Aluminium versus uPVC on price
Beyond the window itself, price is influenced by opening size, glazing specification, powder-coat colour and any structural work needed for larger openings. These are typical guide ranges — your exact price comes from a free, no-obligation survey.
| Aluminium window, standard size | typically £700–£1,300 supplied and fitted |
|---|---|
| Equivalent uPVC window, standard size | typically £400–£850 supplied and fitted, for comparison |
| Aluminium premium for slim sightlines and larger openings | typically 30–70% above equivalent uPVC, varying by project |
Aluminium versus uPVC windows
uPVC windows are generally more cost-effective and perform well thermally, but the frame sections need to be thicker to achieve the same strength as aluminium, which reduces glass area and visible sightlines. Glazing units are fitted within that frame to an energy-rated specification, and the whole frame is finished with a powder coat in the chosen colour.
Longer term, the powder-coated finish should hold its colour without fading or chipping, and a properly specified thermal break should keep the frame's internal face close to room temperature, minimising cold spots and condensation around the window even in winter.

Do aluminium windows corrode or rust?
No — aluminium is naturally corrosion-resistant, which combined with a quality powder-coated finish makes it well suited to exposed positions without the maintenance timber or lower-grade materials would need.
Do aluminium windows help reduce outside noise?
Energy-rated glazing fitted within aluminium frames performs similarly to equivalent glazing in uPVC frames for noise reduction, with the actual glazing specification being the main factor rather than the frame material.
Should I choose aluminium or uPVC windows?
It depends on the project — uPVC is generally more cost-effective and performs well thermally, while aluminium suits larger openings, contemporary designs and heritage-style replacements where slim sightlines and a powder-coated finish matter most. We're happy to talk through which suits your property at survey.
