Fascia Board Materials Compared: uPVC vs Aluminium vs Composite vs Timber

Updated 14 September 2026 · 5 min read

“uPVC or timber” is the comparison most articles stop at, but two more options - aluminium and composite - show up regularly in quotes for period, coastal and higher-end properties across the North West. Here’s how all four actually compare.

uPVC

The default choice for most homes: low cost, no maintenance, 25-30 year typical lifespan, wide range of woodgrain finishes that satisfy most planning requirements outside conservation areas. Its main weakness is that it can look slightly plasticky up close compared with the alternatives, and colour options beyond white and woodgrain are more limited.

Timber

Still required in some conservation areas and on listed buildings where the original was timber. Needs repainting or treating every 3-5 years to prevent rot - a genuine ongoing cost, but the only option that fully replicates a period property’s original appearance.

Aluminium

Increasingly common on coastal and highly exposed properties (Blackpool, Southport, Lancaster’s coastal fringe) because it doesn’t corrode the way steel fixings can, and holds paint finishes extremely well over decades. It costs more than uPVC - often 30-50% more - but for a genuinely exposed site the extra durability is a real factor, not just a premium finish.

Composite

A newer option blending recycled materials with a wood-fibre look. Sits between uPVC and timber on cost, doesn’t need repainting like timber, and gives a more convincing “real wood” appearance than most uPVC woodgrain finishes - a common compromise where a property isn’t listed but the owner wants a period look.

A quick comparison

Which one for your property?

Listed or conservation-area properties: check planning requirements before choosing (see our listed building consent guide). Coastal or highly exposed sites: aluminium or fibre-composite tends to outlast uPVC. Everything else: uPVC remains the sensible default on cost and maintenance alone.
