Why Aluminium? The Comprehensive Comparison
Objective technical analysis comparing Aluminium, Natural Wood, and WPC composite decking.
AVA Aluminium
- ✓ 100% Watertight with perimeter guttering
- ✓ 30-Year warranty against rotting & corrosion
- ✓ Maintenance-free: Never sand, oil, or seal
- ✓ Non-combustible Fire Rating Class A1
- ✓ R11 Slip-resistance safe for bare feet
- ✓ 100% Dimensionally stable in sun & frost
Natural Timber
- ✗ Not watertight (water drips through)
- ✗ Decays, cracks, splinters with age
- ✗ Requires annual sanding and chemical oils
- ✗ Slippery when damp due to algae
- ✗ Combustible fire hazard
- ✗ Short service lifespan (8–12 years)
WPC Composites
- ✗ Not watertight (open board joints)
- ✗ High thermal expansion in summer sun
- ✗ Prone to stains from grease & BBQ oils
- ✗ Can swell, warp, and become brittle
- ✗ Heavy structure, cannot self-support spans
- ✗ Chalks and fades under UV radiation

“We replaced our decaying timber deck after 8 years with AVA Deck Board S. The boards clicked together seamlessly and are 100% waterproof. Finally our ground-floor patio underneath stays completely dry!”
“Outstanding engineering! Thanks to AVA Deck Board L (40 mm), we bridged over 2 metres between cantilever beams without intermediate joists. Saved thousands on steel substructure.”
“Located right by the North Sea, salt air ruins conventional decking. Our AVA aluminium deck has stood through 4 harsh coastal winters without a trace of corrosion. Still looks brand new.”
